Home Loan Refinance Guide | Costs, Equity & Break-Even

THE SHORT ANSWER

A refinance succeeds only when the new loan works through every approval gate.

What does a lender really assess when you refinance?

A lender does not simply check that you already have a mortgage and have been making repayments. It assesses a new credit application. The proposed loan must fit the lender’s refinance purpose rules; your income must be recognised under its policy; the loan must pass its serviceability model; your credit and repayment conduct must be acceptable; the property and valuation must fit security policy; any cash-out, debt consolidation or borrower change must be permitted; and the benefit, documentation and settlement path must make sense.

That is why two lenders can see the same borrower, balance and property value but produce different outcomes. One may recognise more variable or self-employed income. Another may use a different expense treatment, assessment rate, rental-income percentage, cash-out rule, credit score or property restriction. A third may offer a streamlined pathway only if the transaction is genuinely like-for-like.

PRICE

The rate must be real for the scenario

Advertised pricing can depend on occupancy, repayment type, loan amount, LVR, features and product conditions. The lowest public rate is not automatically available or suitable.

POLICY

The borrower and purpose must fit

Income recognition, conduct, property rules, cash-out, debt consolidation and borrower changes can narrow the product set before price is compared.

OUTCOME

The change must improve the full position

Repayment, total interest, remaining term, fees, offset value, risk and future plans should be compared—not just the first-month payment.

Intent boundary: this guide explains the mechanics and policy in depth. The separate Refinance & Rate Review service page is where you run the stay/reprice/switch decision and request a personalised review.

AUSTRALIAN REFINANCE DATA

Refinancing is a major market—and a large share happens without changing lenders.

The Australian Bureau of Statistics separates internal refinancing, where the borrower remains with the same lender, from external refinancing, where the loan moves to a different lender. That distinction matters because a useful review should compare negotiation and internal restructuring with a full external move.

Internal refinancing is not a minor pathway

Internal owner-occupier and investor refinancing totalled about 64,000 commitments in the quarter. A current-lender solution can therefore be a serious option, not merely a negotiating tactic.

External switching still dominates by number

External moves represented about 62% of all refinance commitments and about 64% of their value in the quarter, showing that many borrowers still found a reason to change lenders.

The data does not show suitability

Commitment data records transactions, not whether the borrower improved total interest, retained useful features or selected the best policy path. Those questions require a loan-level review.

What the market data means for one borrower

Do not start with “Which lender should I move to?” Start with “What problem must the next loan solve?” The answer may be a lower price with the same lender, an internal product change, a full refinance, or a decision to wait while equity, conduct or documentation improves.

REFINANCE MECHANICS

“Refinance” can describe five very different transactions.

The amount of reassessment, documentation and settlement work depends on what is actually changing. A clean rate-only move is not the same credit event as releasing equity, consolidating debts or changing borrowers.

Common refinance transaction types and the policy issues they create.
Transaction	What changes	Typical assessment intensity	Key questions
Repricing	The existing lender changes the rate while the loan and security remain substantially the same.	Often the lightest path because there is no new lender or mortgage settlement.	Is the new rate genuinely competitive? Are fees or features still weak? Is there a better internal product?
Internal product switch	The borrower remains with the lender but changes product, repayment type, fixed/variable mix, offset or package.	Can range from administrative to a fuller reassessment, depending on the change.	Does the switch alter repayments, loan purpose, term, interest-only status or available credit?
External like-for-like refinance	A new lender pays out the old loan with similar borrowers, security, balance and repayment structure.	Usually a full new application unless a narrow streamlined policy applies.	Does the borrower pass current income, conduct, servicing, valuation and security rules?
External restructure	The refinance changes term, loan splits, repayment type, borrower mix, security or guarantees.	Usually a full assessment because the new risk is not like-for-like.	Why is the structure changing? Does it remain suitable? Are title, tax or legal consequences involved?
Refinance with additional lending	The new loan includes cash-out, renovation funds, an investment deposit or debt consolidation.	Full assessment with purpose and evidence requirements that vary by amount and LVR.	What are the funds for? How will they be controlled? Is total debt and long-term interest increasing?

What happens at settlement?

For an external refinance, the new lender advances enough to pay out the agreed balance of the old loan and approved costs or additional lending. The old mortgage is discharged and the new mortgage is registered. Existing offset accounts, direct debits and salary credits do not automatically transfer, so the operational changeover matters as much as the approval.

Why an existing loan is not proof that a new loan will be approved

The original loan may have been approved under different interest rates, income, expenses, dependants, debts, property values and policy. A refinance is assessed at the new application date. A borrower can have perfect mortgage conduct yet fail a new lender’s serviceability model, or pass serviceability but fail a cash-out, security, credit-score or documentation rule.

THE SEVEN-GATE MODEL

Think of refinance approval as seven linked decisions—not one credit score.

A strong application is designed so the transaction can move through all seven gates. Passing six does not compensate for failing the seventh.

GATE 1

Purpose and benefit

The lender and broker need to understand what the refinance is intended to achieve. A rate-only switch, equity release, consolidation and borrower change are different purposes with different risks.

GATE 2

Income recognition

The lender decides which income sources are acceptable, how much of each source is used, which history period applies and what evidence is sufficient.

GATE 3

Serviceability

Recognised income is tested against sensitised loan repayments, existing liabilities, living expenses, dependants and the proposed term and repayment type.

GATE 4

Credit and conduct

Credit enquiries, repayment history, arrears, hardship arrangements, defaults and the conduct of debts being refinanced or retained can all affect the path.

GATE 5

Property and valuation

The accepted valuation sets LVR, while property type, location, size, title, condition, marketability and use determine whether the security is acceptable.

GATE 6

Structure and policy

Borrower names, loan splits, fixed/variable mix, interest-only terms, cash-out, guarantees and security links must fit the lender’s policy and the borrower’s objective.

GATE 7

Execution, conditions and settlement

Approval can still stall if documents expire, valuation access fails, discharge forms are delayed, payout figures change, conditions are not satisfied or the new accounts and repayments are not set up correctly. A refinance is complete only when the old loan has been paid out and the new structure is operating as intended.

Important: no online guide can tell you that all seven gates will be passed. The value of this detail is that it helps you identify the right questions before an application is lodged. It cannot turn a public guide into an approval prediction.

WHY LENDERS DIFFER

The same refinance can fit one type of lender far better than another.

A large bank is not automatically stricter, and a smaller lender is not automatically more flexible. What matters is whether that lender’s systems, pricing and credit rules suit the particular issue in your application.

MAJOR-BANK MODEL

Strong when the file is clean and standard

Major lenders can be fast and sharply priced for straightforward PAYG, well-documented self-employed and standard-property refinances. Automated scoring and set workflows can make unusual exceptions harder to accommodate.

SECOND-TIER / MUTUAL MODEL

Mainstream lending with different niches

These lenders can combine competitive pricing with more manual assessment or different rules for income, property and loan structure. Membership, location, channel or security limits may still apply.

NON-BANK MODEL

Useful where mainstream policy is a poor fit

Non-banks can provide extra options for some self-employed, credit, cash-out or property scenarios. The rate, fees, valuation approach and longer-term exit plan need to be compared carefully.

SPECIALIST MODEL

More complex situations, usually at a higher cost

Specialist lending may consider adverse credit, alternative documents or structures that standard channels will not. The refinance should include a clear improvement plan and a realistic route back to lower-cost lending where possible.

Flexibility is specific to the problem

A lender may accept a borrower on probation but be conservative on small apartments. Another may work well with one year of self-employed figures but restrict cash-out. A third may use more rental income but apply a tougher credit score. The useful question is not “Which lender is easiest?” It is “Which policy fits the actual issues in this refinance?”

Four trade-offs worth comparing

Policy flexibility versus price: a niche solution may carry a higher rate or fee.
Automation versus human assessment: automation can speed up a standard file but leave less room for an exception.
Product features versus simplicity: offsets, splits and package benefits can be valuable, but only when you will use them.
Approval today versus the next review: a higher-cost solution should include a realistic plan for what improves and when the loan will be reviewed again.

How to read the ranges in this guide: when a section says a policy can run from 70% to 90%, it does not mean every lender offers every point in that range. It shows the broad window you may encounter. Your actual result still depends on the product, LVR, income evidence, credit history, property and loan purpose.

SERVICEABILITY

Paying your current mortgage on time helps—but a new lender still rebuilds your budget.

Your repayment history shows what you have paid. Serviceability tests whether the proposed loan works after the lender adjusts your income, loads your debts, checks your expenses and applies a higher assessment rate.

What is the mortgage serviceability buffer?

APRA-regulated banks must use at least a three-percentage-point buffer above the loan rate when assessing new mortgage borrowing. Some tightly controlled refinance-exception pathways use a smaller buffer of roughly one to two percentage points, but they usually require a clean like-for-like transaction, moderate LVR, strong repayment conduct and other strict conditions. A reduced buffer is therefore a narrow policy pathway—not a general shortcut around serviceability.

Not every dollar of income is used

Base salary is usually the simplest. Overtime, bonus, commission, rent, foreign income and self-employed profit can be averaged, shaded, capped or excluded. The later income sections show the common ranges.

Debt limits can matter more than current balances

Credit cards and lines of credit are often loaded at about 1.5%–5% of the approved limit each month, with roughly 3%–3.8% common. BNPL may be treated as a living expense, the actual payment or a card-style commitment. Total debt can also attract extra scrutiny around five to six times gross income, with practical limits often emerging around six to eight times.

Expenses are checked, not simply accepted

Lenders generally use the higher of declared spending, verified spending and a household benchmark. Bank-statement review often covers about one to three months, with a longer period requested when the pattern is unclear or materially different from what was declared.

Common serviceability differences that can change the answer

Input	How the assessment can change	What it means for a refinance
Assessment rate	Standard assessment commonly starts with the product rate plus at least three percentage points or a floor rate. A narrow refinance exception may use roughly one to two points instead, while still applying a floor and credit conditions.	A lower advertised rate helps, but it does not automatically create more borrowing capacity. The assessment method must also fit.
Credit cards and lines of credit	The monthly commitment can be based on about 1.5%–5% of the limit rather than the balance, with 3%–3.8% a common range.	Reducing or closing an unused limit can improve the result more than simply paying the latest statement.
BNPL and short-term credit	It may be treated as declared spending, an actual repayment, a personal-loan commitment or a card-style loading—often around 3.8% of the facility limit.	Several small facilities can materially reduce the surplus even when each balance appears modest.
HECS/HELP	Most lenders model the statutory repayment from taxable income. Some may treat it differently when full repayment is clearly close—often within about one year and sometimes within a defined one-to-five-year period.	The payslip deduction is not always the final commitment used in the calculator.
Rental income	Standard residential rent is often recognised at about 70%–90%. A lender may use up to 100% only when vacancy and property expenses are loaded elsewhere.	Investors with the same rent and debts can receive quite different servicing results.
Existing mortgages	The lender may use the actual repayment, a sensitised repayment, the facility limit or the future principal-and-interest payment after an interest-only period.	Retained investment loans can be the main reason one refinance works and another does not.
Living expenses	Declared expenses are checked against bank statements and a benchmark, commonly using about one to three months of transaction history.	A lender with the lower rate can still produce the weaker serviceability result.
Loan term and age	A longer term reduces the modelled repayment, but most mainstream loans still centre on 30 years and longer terms can trigger retirement or exit-strategy questions.	Extending the term can improve the calculator while increasing long-term interest and future risk.

Do not treat serviceability as borrowing capacity: these ranges explain why results move. Exact capacity requires complete borrower data, current lender calculators and a full policy check.

PAYG & NON-STANDARD INCOME

The income shown on a payslip is only the start of the lender’s decision.

Lenders do not treat every dollar of employment income the same way. Time in the job, probation, the stability of hours, how often an allowance is paid and how much history is available can all change the amount used in the refinance assessment.

How common employment and income types are usually checked during a refinance.
Income type	What the lender will look at	Where the answer can move	What to prepare
Permanent PAYG	Employment status, time in role, base pay, payslip quality and year-to-date consistency. Current-employer requirements can run from no minimum through to about six months; where the role is new, around 12–24 months of continuous work in the same occupation or industry can provide extra comfort.	Some lenders will use the income immediately. Others want more evidence where the role, employer, hours or remuneration have recently changed.	Current payslips, salary credits and a short explanation of any recent change. If the role is new, keep evidence of prior same-field employment.
Probation / recent job change	How long probation has left to run, whether the role is permanent and whether the borrower has continuous experience in the field. Some lenders accept income while probation remains; others want it completed, particularly without roughly 12–36 months of same-field history.	A move to a similar role can be treated very differently from a complete occupation change.	Employment contract, commencement date, role description and prior same-field work history.
Casual	Time in casual employment, average hours, year-to-date income and seasonal variation. Around three to 12 months in the current role is common, while stricter settings can look for 12–24 months of industry continuity.	A strong recent run of shifts may be averaged or shaded if it is not supported by a longer pattern.	Multiple payslips, income summaries, bank credits and an explanation of stable hours or industry continuity.
Fixed-term contract	Contract expiry, renewals, remaining term, occupation and the likelihood of continued work. Current-role evidence often falls around three to 12 months, with 12–24 months of contracting continuity useful on a weaker file.	A long career built through contracts can be viewed more favourably than a first short contract close to expiry.	Current contract, renewal history and evidence of continuous work in the field.
Overtime	History, consistency, whether it is regular or essential to the role, and the recent trend. Recognition can range from about 50% to 100%, with 80% common, using roughly three to 24 months of evidence.	One lender may use an average, another a fixed percentage, and another the lower of two periods. Essential-services overtime may receive different treatment.	Separate base income from overtime and provide enough history to show that the pattern is repeatable.
Bonus / commission	Frequency, discretion, historical average, year-to-date amount and the latest-year direction. Recognition can range from about 50% to 100%, with 80% common, and 12–24 months of history is often required.	A strong latest year can be pulled back by a lower prior year; some calculations cap growth at around 120% of the previous year.	Two years of evidence where available, current year-to-date figures and the remuneration plan.
Parental leave	Return date, return income and hours, the paid and unpaid leave periods and how commitments are met during the gap. Return-to-work windows commonly sit around three to 12 months, with roughly 50%–100% of return income considered depending on the evidence and savings buffer.	Some lenders work from confirmed return income; others rely more heavily on current income, particularly where the leave period is longer or the buffer is thin.	Employer confirmation, paid-leave details and evidence of savings or other resources covering the leave period.
Foreign income	Currency, country, tax status, conversion, evidence and payment history. Accepted income can range from about 50% to 100% after currency and tax treatment, with 70%–90% common and around three to six months of evidence often expected.	Accepted currencies and shading differ materially; more restricted pathways frequently cap LVR around 70%–80%.	Contracts, payslips, bank credits, tax evidence and translations where required.

A practical rule for variable income

Build the refinance around income that is evidenced and reasonably repeatable—not the best recent month. Then check whether the loan still works if the lender uses only 80%, averages a longer period or caps a strong latest year.

SELF-EMPLOYED REFINANCING

A profitable business can produce several different “usable income” answers.

A new lender has to turn business accounts into a sustainable personal-income figure. The answer can change depending on how long the business has traded, which financial years are used, whether growth is capped, which add-backs are accepted and which business debts remain after settlement.

Why self-employed refinance assessment is different

Full-document assessment commonly uses one or two completed financial years and often works best once the business has around 18–24 months of history. Selected alternative-document paths can start from about six months of trading, but they normally require stronger credit, a clearer purpose and more equity. Those paths often use about three to six months of business bank statements or six to 12 months of BAS, with maximum LVRs ranging broadly from about 65% to 90% and 75%–80% more common.

The seven-step income reconstruction

Identify the structure

Sole trader, partnership, company and trust income flow differently. Related entities can also create hidden income, debt or ownership links.

Confirm ownership and control

Your ownership percentage, director role, beneficiary position and control affect which profit may be used and whether retained earnings are genuinely available.

Select the evidence period

The lender may use the latest year, a two-year average, the lower year or a latest-year figure constrained by sustainability rules. One strong year does not create the same result everywhere.

Read the trend

Growth, stability and decline matter. Where the latest year jumps sharply, some lenders cap the usable result at about 120% of the prior year rather than taking the full increase.

Test add-backs

Depreciation may be fully added back in one assessment and capped—sometimes around 20% of profit—in another. Interest, director wages and one-off costs also need evidence and must not be counted twice.

Include business commitments

Vehicle finance, tax debts, working-capital facilities, leases and guarantees can reduce or remove the benefit created by an add-back.

Choose the evidence path

Full financials, a latest-year assessment, BAS/interim evidence or an alternative-document path must fit the current business, loan purpose, credit profile and LVR.

CHECK

Reconcile to current cash flow

High accounting income that is not supported by current trading, tax payments or bank conduct may not provide a durable refinance answer.

Common add-backs—and why they are not automatic

Potential item	Why it may be considered	Why the amount can be reduced or rejected
Depreciation	It is a non-cash accounting expense and may be added back.	Some assessments accept the full supported amount; others cap it, including settings around 20% of profit, or restrict property-related depreciation.
Interest expense	Interest on debt being refinanced may cease or change after settlement.	The underlying business debt may remain, only part may be refinanced, or the new repayment still needs to be included.
Director salary	Salary can be added back to company profit when it has already reduced that profit.	It cannot then be counted again as separate PAYG income without removing the duplication.
One-off expense	A genuine non-recurring legal, relocation, repair or abnormal cost may not repeat.	The expense may actually be part of normal operations, may recur or may not be adequately evidenced.
Excess superannuation	Contributions above compulsory levels may be discretionary in some structures.	They may be required by an employment arrangement, cash-flow need or the owner’s retirement plan.
Retained profit	Profit retained in a controlled company or trust may support the owner’s position.	Working-capital needs, other owners, tax, dividends, solvency and access to funds can limit reliance.

What can make a strong business fail a refinance?

An incomplete financial year, falling revenue, unresolved tax debt, large business commitments, inconsistent BAS, unsupported add-backs, multiple related entities or cash-out that is not clearly separated from business use.

What can improve the file?

Current financials, a clear structure chart, a reconciled tax position, evidence of recurring income, a reasoned add-back calculation, separated business and personal debts and a loan purpose documented before the lender is selected.

CREDIT & REPAYMENT CONDUCT

A new lender checks the whole credit story—not only the mortgage being refinanced.

The lender may use your credit report, open-banking data, loan statements or a combination. How far it looks back and what it will tolerate depends on the type of refinance, the seriousness of any issue and how long the position has been stable since then.

REPAYMENT HISTORY

Most checks cover months, not just the latest statement

Mortgage and liability conduct is commonly checked over about three to 12 months. Six months is common; streamlined or exception pathways often want a full 12-month picture.

CREDIT FILE

Recent and older events can both matter

A clean period of roughly six to 12 months is often important, while defaults, judgments and other adverse events may be considered over about 24 months or longer.

EXPLANATION & RECOVERY

A limited issue is not treated the same as repeated stress

Some policies require no late events. Others may consider one payment up to 29 days late when the cause is documented. After hardship, a stable recovery period of roughly six to 24 months may be needed, depending on the circumstances.

What appears on an Australian credit report?

Repayment history information can show whether payments were made on time and remains on a credit report for two years. A payment more than 14 days late can be recorded as missed. Financial hardship information remains for one year, while defaults generally remain longer. The report shows the event, but it may not explain why it happened or what has changed since.

Evidence	What it can show	Why more information may still be needed
Comprehensive credit report	Facility limits, repayment history, enquiries and certain adverse information.	Not every provider reports every field equally. Business, trust or non-reporting debts may still need statements.
Home-loan statements	Balance, interest, redraw, arrears and the actual payment pattern. The requested period commonly runs from about three to 12 months.	Statements are often required when credit-report data is incomplete, a late event needs context or a streamlined path requires a full 12 months of clear conduct.
Open-banking data	Current account and debt transactions supplied through a consented data connection.	It can speed up verification, but it does not remove a lender’s document or policy requirements.
Hardship history	That repayment obligations were temporarily or permanently varied.	The new lender may want the current contractual repayment, completion evidence and a stable period after the arrangement—often somewhere around six to 24 months.
Written explanation	Cause, timing, resolution and what is different now.	An explanation supports the facts; it does not override a hard rule or ongoing poor conduct.

Do not hide repayment difficulty. If repayments are becoming hard to meet, contact the existing lender early and consider free financial counselling. A rushed refinance is not a reliable substitute for hardship assistance, and repeated applications can make the position more difficult.

STREAMLINED REFINANCE

A streamlined refinance is a narrow lane for a very specific type of application.

Some lenders have an alternative assessment for a clean, like-for-like refinance where the new loan lowers or does not increase the repayment. It is not an automatic low-doc approval and it is not available simply because the proposed rate is lower.

LIKE-FOR-LIKE PATH

What the application commonly needs to look like

the same borrowers and substantially the same security;
an LVR at or below about 80% and no new mortgage insurance;
the existing loan held for roughly 12 months, with up to 12 months of clean mortgage and other debt conduct;
principal-and-interest to principal-and-interest, or another specifically permitted repayment type;
a new contractual repayment that is the same or lower;
little or no additional borrowing—some paths allow only costs or a small increase of about $5,000–$50,000, while others use a limit such as $10,000 or 1%;
no material adverse change expected in the borrower’s circumstances.

FULL-ASSESSMENT PATH

Changes that usually move the file out

meaningful cash-out or a large increase in the loan limit;
debt consolidation, especially where conduct is weak;
adding or removing a borrower or changing the title;
moving from principal-and-interest to interest-only;
a guarantor, company, trust or more complex security structure;
recent arrears, hardship or other financial stress;
a property or valuation issue requiring a wider credit decision;
total debt around five to six times income or above the pathway’s DTI limit.

Question	Streamlined-style assessment	Full assessment
Purpose	Usually a clean refinance with an obvious financial benefit and minimal change.	Can consider broader restructures, cash-out and additional lending subject to standard policy.
Assessment rate	Some qualifying paths use a reduced buffer of roughly 1%–2% rather than the standard three-point reference. A floor rate and credit approval can still apply.	Current income, expenses and liabilities are assessed under the standard buffer, floor and servicing method.
LVR and loan history	About 80% LVR is the common ceiling, with the existing loan generally held for around 12 months.	Higher LVRs or shorter loan history may still be considered under ordinary policy, subject to insurance, pricing and risk.
Conduct	Clean conduct—often a full 12 months—is central to access.	Conduct is still assessed, but a broader explanation or specialist pathway may be available.
Extra lending	Can range from none to a small controlled amount, often around $5,000–$50,000 or only enough to cover refinance costs.	Larger documented amounts can be considered where purpose, serviceability and LVR all work.
Best use	A genuinely comparable loan where the repayment and overall risk are not increasing.	Cash-out, consolidation, complex income, borrower changes, interest-only or a tailored structure.

Why “mortgage prisoner” discussions need care

A borrower who does not pass standard serviceability may still have options to investigate, but a lower proposed rate alone does not create an entitlement to refinance. Conduct, LVR, benefit and transaction type must all fit the exact pathway. Where hardship exists, the current lender’s hardship team and free financial counselling should also be considered.

EQUITY, VALUATION & SECURITY

Your equity is usable only after the new lender accepts the property and its value.

The property is not just background security. Its value, size, title, location, condition and marketability can change the maximum LVR, the price and whether the lender will accept the refinance at all.

How is refinance LVR calculated?

Loan-to-value ratio = proposed loan amount ÷ accepted property value. The important word is accepted. An online estimate, council value, agent appraisal or old valuation can help with planning, but the new lender decides which valuation method and figure it will rely on.

$600,000 proposed loan÷$800,000 accepted value=75.0% LVR

$600,000 proposed loan÷$740,000 accepted value=81.1% LVR

The loan did not change, but the lower valuation moved it from below 80% LVR to above it. That can affect pricing, mortgage insurance, cash-out limits and which policies remain available. Standard residential security can reach roughly 80%–95% LVR in some circumstances, but unusual property features often pull the maximum back.

Property issues that can change the lender shortlist

Apartment size and density

Minimum internal areas can run from about 25 m² at the flexible end to 50 m² at the stricter end, with 40–50 m² common. Units around 25–40 m² are often limited to roughly 60%–70% LVR or require a strong metropolitan location. High-density, serviced, student and short-stay properties can be narrower again.

Land, acreage and rural use

Standard residential-land settings commonly sit around 1,500 m² to two hectares. Selected rural-residential or lifestyle policies extend to roughly 10–50 hectares, often with a lower LVR around 60%–70% and tighter tests for zoning, access, services and marketability.

Title and tenure

Company title, leasehold, stratum, community title, multiple titles, crown lease and other title forms can require a narrower lender or a lower LVR. Short lease terms and unusual ownership structures can fall outside standard policy.

Condition and approvals

Incomplete works, unapproved structures, major defects, cladding, contamination or poor maintenance can reduce the value, create a retention or make the property unacceptable until the issue is resolved.

Marketability and location

A highly specialised dwelling, mixed-use property, very small unit or property in a thin regional market may attract a lower LVR. Postcode limits can also narrow the product or mortgage-insurance options.

Valuation method

An automated, desktop, kerbside or full inspection can produce different confidence and evidence. Cash-out, recent works or unusual security often requires a fuller valuation.

How to prepare for the valuation

Use a realistic value range rather than the highest online estimate.
Make the property accessible and present major improvements clearly.
Keep approvals, plans and building information for substantial works.
Identify unusual title, zoning, lease or use before choosing a lender.
Model the refinance at more than one value, especially around an LVR threshold.
Do not commit cash-out funds until the accepted value and approval are known.

CASH-OUT & EQUITY RELEASE

Equity release is new borrowing—even when the property has risen in value.

The amount, purpose, evidence, LVR and repayment history all matter. Maximum cash-out LVRs commonly sit somewhere around 70%–90%. A small release may need only a clear purpose, while amounts around $50,000–$100,000 often trigger more detailed evidence. Larger well-documented purposes can still be considered under a full assessment.

Purpose	Common evidence or structure	Main questions to answer
Renovation	Quotes, plans, invoices or a building contract. Cosmetic work may remain normal cash-out; structural, staged or incomplete work can move into renovation or construction policy.	Is the amount below the lender’s evidence threshold, or does it need controlled progress payments and an on-completion valuation?
Investment-property deposit	Separate loan split, purchase budget and evidence of the intended acquisition.	Can both debts be serviced? Is the use of funds clear for tax records? Is unnecessary cross-collateralisation being avoided?
Personal investment	Purpose statement, adviser documentation, account details or transaction evidence.	Does the amount fit the borrower’s position and risk tolerance? Is the home securing a volatile investment?
Business use	Business plan, invoice, accountant information, financials or a commercial-purpose review.	Is a consumer home loan the right product? Does the business risk place the home at greater risk?
Debt consolidation	Statements, payout figures, closure instructions and a separate split or repayment plan.	Will the old limits be closed? Does the lower payment simply stretch the debt over decades? Is the recent conduct acceptable?
Unspecified cash reserve	A clear declared purpose becomes increasingly important as the amount rises. Light-evidence releases can range from none or a few thousand dollars to roughly $50,000.	Open-ended “cash at bank” is harder to assess and can attract tighter limits or direct payment controls.

Five questions before releasing equity

What exact amount is required? Borrowing the maximum available equity increases interest. A higher requested LVR can also move the file from a broad 80%–90% lane into a much narrower one.
What will the funds be used for? Once the request reaches roughly $50,000–$100,000, quotes, contracts or purchase evidence commonly become more important. Larger documented renovations, investments or business purposes can extend beyond $100,000 under full assessment.
Should the funds be a separate split? Separate splits improve control, repayment tracking and record keeping, particularly where investment or business use may have tax consequences.
What is the repayment plan? The funds should not become permanent mortgage debt by accident. Some lenders also pay creditors or suppliers directly rather than releasing unrestricted cash.
What happens if the valuation is lower? The plan should include a smaller release amount or another source of funds.

Usable equity is not spending capacity. Property equity provides security, but serviceability and suitability still determine whether additional borrowing should proceed.

DEBT CONSOLIDATION

A lower monthly repayment can improve cash flow and still increase the long-term cost.

Debt consolidation is commonly assessed around 80%–90% LVR, with about three to 12 months of repayment history checked. Many lenders pay the creditors directly and require the old accounts to be closed. Some streamlined refinance paths do not allow consolidation at all; others cap it somewhere between nil and roughly $50,000.

ILLUSTRATIVE $25,000 DEBT

Short-term debt before consolidation

12% over 5 years: about $556 per month and about $8,367 total interest.

Rolled into a 25-year mortgage split

6% over 25 years: about $161 per month but about $23,323 total interest if only minimum repayments are made.

Same mortgage rate, disciplined 5-year payoff

6% over 5 years: about $483 per month and about $3,999 total interest.

What the example demonstrates

The 25-year structure creates the biggest immediate cash-flow relief, but it also creates the highest total interest because the debt remains for far longer. The right question is not simply whether to consolidate. It is whether the new structure fixes the cash-flow problem without quietly turning short-term debt into a 20- or 30-year mortgage.

A stronger consolidation structure

Use a separate split, pay the creditors directly, close or reduce the old limits, set a repayment target closer to the original debt term, prevent balances rebuilding and consider financial counselling or budgeting support where the debt pattern is ongoing.

Why the outcome can differ

LVR: the common range is roughly 80%–90%, but larger unsecured balances or weaker conduct can reduce the maximum.
Conduct: the lender may check about three to 12 months of statements and require a longer clean run where arrears, over-limit conduct or repeated short-term credit appears.
Payout control: direct payout and closure are common. If limits remain open, they may stay in serviceability or be rebuilt after settlement.
Number and type of debts: some policies cap the number or total value of facilities and exclude business or private debts.
Streamlined eligibility: a like-for-like refinance may exclude consolidation altogether or permit only a tightly controlled amount up to roughly $50,000.
Repayment term: the monthly payment can fall purely because the debt is stretched over 20–30 years, so the consolidated split should have its own faster repayment target.

INVESTOR REFINANCING

Investor refinancing is a portfolio and record-keeping decision—not only a rate decision.

The lender has to decide how much rent to use, how to assess every retained loan, what happens when an interest-only period ends and whether the new loan structure keeps investment and private purposes clearly separated.

RENT

Only part of the gross rent may be used

For standard residential property, about 70%–90% of gross rent is common. Some calculators use up to 100%, usually because vacancy and property expenses are loaded elsewhere. Holiday, specialist or commercial-style rent can range more widely—from about 45% to 90%, with 50%–80% a common working range.

DEBT

Every retained loan is reassessed

Interest-only expiry, facility limits, retained mortgages and sensitised repayments can make a portfolio look very different from its current cash flow. The future principal-and-interest payment often matters more than today’s minimum.

STRUCTURE

Loan separation protects future flexibility

Separately secured loans and clear splits can make a future sale or refinance simpler. Cross-collateralisation may be convenient today but give the lender more control over future security releases.

Tax tracing follows the use of borrowed money

For Australian tax purposes, interest deductibility generally follows what borrowed funds are used for, not simply which property secures the loan. Refinancing the same investment debt may preserve the relevant character, while additional borrowing for private use can require apportionment. Mixed-purpose redraws make record keeping difficult. Obtain tax advice before restructuring or releasing equity.

Decision	What to check	Risk if ignored
Rental evidence	Evidence commonly covers about three to 12 months and may include a lease, statements, tax returns, valuation rent or a recent appraisal. Appraisals and agent statements are often expected to be no more than about 30–60 days old.	The lender may use a lower figure or disregard income that is not current or well supported.
Rental-yield cap	Some calculators cap usable rent at roughly 5%–7% of the property value unless stronger evidence supports the claimed amount.	An unusually high rent may not produce the servicing benefit expected.
Negative gearing	The benefit may be ignored, partly recognised or fully modelled depending on the policy and current rule set.	Two lenders can use the same rent and interest expense but produce materially different surplus income.
Interest-only renewal	Initial IO periods commonly run around one to five years. Check the assessed and actual repayment when the loan returns to principal-and-interest.	A lower current payment can hide a large future increase.
Equity release for a deposit	Use a separate split and document the next acquisition. Recognised rent generally follows the borrower’s ownership share.	Mixed purposes, poor tax records and unnecessary cross-collateralisation.
Portfolio or sale planning	Check whether one loan or security can move without re-assessing or disturbing the rest of the portfolio.	Multiple valuations, discharge complexity or a lender-controlled partial debt repayment when a property is sold.

TERM, FIXED RATES & FEATURES

The repayment can fall even when the long-term loan becomes more expensive.

Start by comparing the current and proposed loan over the same remaining term. Then show any intentional term extension separately, including the extra interest, future repayment changes and any retirement or exit-strategy questions.

TERM-RESET EXAMPLE

$500,000 with 20 years remaining at 6.40%

Estimated principal-and-interest repayment: $3,698 per month. Estimated remaining interest: $387,637.

Refinanced to 5.90% over a fresh 30 years

Estimated repayment: $2,966 per month. Estimated total interest: $567,646.

Refinanced to 5.90% while retaining 20 years

Estimated repayment: $3,553 per month. Estimated total interest: $352,809.

What changed?

The 30-year option created the largest monthly reduction, but the estimated interest was about $214,837 higher than using the same 5.90% rate over 20 years. A term extension can be appropriate for cash-flow reasons, but it should be an explicit decision rather than the hidden source of the “saving.”

The same-term comparison rule

Compare the current and proposed loan using the same remaining term first. Then model the longer-term option separately and show the extra interest and the repayment plan if cash flow improves.

Where policy enters: 30 years remains the common mainstream maximum. Some products extend to roughly 31–40 years, usually with tighter age, purpose and exit-strategy conditions. Extra retirement review often begins around age 45–55 or when the proposed maturity runs beyond roughly age 67–70.

Features that can be worth more than a small rate difference

Offset account

An average $50,000 held in a 100% offset against a 6% loan can avoid roughly $3,000 of interest in the first year, before fees and balance changes. Compare the balance you will actually keep—not the feature label alone.

Redraw

Redraw can provide access to additional repayments, but access rules can change and the tax treatment of redrawn funds may depend on their use.

Loan splits

Separate investment, private, fixed, variable or consolidation purposes. Too many splits can add administration and package complexity.

Fixed rate

Fixed rates provide payment certainty but can restrict extra repayments, offset access or early exit. Obtain a current break-cost estimate before relying on a projected saving.

Interest only

Initial IO periods commonly run about one to five years. Lenders normally assess the future principal-and-interest repayment over the shorter remaining term, so the payment after IO can be materially higher.

Package pricing

Annual fees may be worthwhile when rate discounts, offsets or linked products create real value. Compare the package over the period you expect to keep it.

COSTS & BREAK-EVEN

Calculate the cost of changing, the cost of staying and the cost of time.

Moneysmart identifies fixed-rate break fees, discharge fees, application fees, switching fees and possible government charges as items to check. The exact mix changes by lender, product, state, title and transaction.

Cost or value item	Where it arises	How to compare it properly
Current-lender discharge fee	Closing the existing mortgage and loan.	Use the current lender’s payout or fee schedule, not a generic estimate.
Fixed-rate break cost	Ending or changing a fixed loan before expiry.	Request a current estimate; it can change with wholesale rates and time remaining.
Government registration charges	Discharging and registering mortgage interests.	Use current state or territory fees and the actual title structure.
Application, settlement, legal or valuation fees	The proposed new loan.	Check which fees are charged, waived, capitalised or refundable.
Annual or monthly fees	Package, account or product administration.	Model them across the expected holding period, not just in year one.
LMI or risk fee	Often relevant when the accepted LVR is above a lender threshold.	Existing LMI generally does not simply transfer. Repricing or waiting may be stronger.
Cashback or incentive	Promotional offer from the new lender.	Check eligibility, minimum balance, timing, clawback and whether the underlying loan remains competitive.
Lost feature value	Offset balance, redraw access, linked benefits or repayment flexibility.	Estimate the likely dollar value and practical importance, not just the fee.
Delay cost	Time spent waiting on documents, valuation, discharge and settlement.	Include the interest-rate difference during the expected transition where material.

Total one-off switching costs÷monthly net saving=approximate break-even months

Break-even is necessary but not sufficient

A six-month break-even can still support a poor refinance if the loan resets to 30 years, removes a valuable offset, mixes deductible and private purposes, introduces an unsuitable interest-only term or is likely to be replaced again soon. A longer break-even may still be acceptable when the primary benefit is risk control, separation of securities or a structure needed for a future transaction.

Three-year view

Useful for testing whether the likely repayment difference exceeds one-off costs over a realistic review period.

Remaining-term view

Shows the total-interest effect when the rate and term are kept comparable.

Stress view

Tests a lower valuation, smaller rate gap, reduced income or earlier sale so the recommendation is not dependent on the best case.

DOCUMENTS & EVIDENCE

The fastest refinance file is the one with the right evidence first time.

Credit reporting and digital bank data can reduce paperwork, but they do not remove the need for evidence where the income, repayment history, property or cash-out purpose is not fully clear.

Prepare the baseline documents, then add the evidence that matches your situation.
Scenario	What is commonly needed	Timing and purpose
Every refinance	Identification, current loan balance and limit, rate, remaining term, repayment type, fixed expiry, property details, liabilities and living expenses.	Mortgage and liability conduct commonly covers about three to 12 months. The documents should all describe the same current position and proposed benefit.
Standard PAYG	Recent payslips, salary credits, employment details and sometimes an employment letter.	Payslips and employer letters commonly need to be no more than about 30–60 days old. Around three months of salary credits may be used to confirm the pattern.
Variable PAYG	Longer payslip history, income statements, prior-year evidence and remuneration terms.	Overtime, bonus and commission evidence can cover roughly three to 24 months, depending on how often it is paid and how it must be averaged.
Casual or contract	Multiple payslips, employment contract, renewal history, year-to-date income and prior employment.	Current-role history commonly sits around three to 12 months, with 12–24 months of wider industry continuity useful for stricter assessments.
Parental leave	Employer letter, return date and hours, paid-leave details, government payments and savings buffer.	The documents must show the income on return and how commitments will be met during any gap.
Self-employed	Personal and business tax returns, notices of assessment, financial statements, BAS, interim accounts, business bank statements and related-entity documents.	Full-doc assessment commonly uses one or two completed financial years. Alternative paths may use around three to six months of business statements or six to 12 months of BAS.
Investor	Lease, rental statements, tax returns, rates, property expenses and all investment loan statements.	Rental evidence commonly covers about three to 12 months. Agent statements and appraisals are often expected to be no more than about 30–60 days old.
Cash-out	Quotes, invoices, contracts, purchase evidence, adviser or accountant information and a clear purpose statement.	Purpose evidence commonly becomes more detailed once cash-out moves into roughly the $50,000–$100,000 range, with larger or unusual purposes requiring fuller contracts or controlled payment.
Debt consolidation	Statements for each debt, payout figures, repayment history and closure instructions.	Expect about three to 12 months of conduct evidence. The lender needs the exact payout and proof of which facilities will be closed.
Credit issue or hardship	Credit report, statements, arrangement details, completion evidence and a concise written explanation.	The lender will look at the cause, current obligation and the stable period since the event, which can range from roughly six to 24 months.
Property exception	Floor plan, title, lease, zoning, approvals, building report, insurance, tenancy or improvement evidence.	The evidence is used to confirm security type, size, condition, marketability and the assumptions behind the valuation.
Borrower or title change	Legal agreement, transfer documents, relationship-property advice, trust/company documents and relevant consents.	The lender needs to know who will own, borrow, guarantee or benefit after settlement and whether legal or tax advice is required.

A clean submission tells one consistent story

The application form, credit report, statements, payslips, tax documents and purpose explanation should reconcile. Unexplained differences—such as undeclared debts, income that does not match bank credits, a cash-out amount that changes between documents or a property use that conflicts with the loan purpose—create delay and can undermine confidence in the file.

Document age matters

Current payslips and employer letters commonly expire after about 30–60 days. Salary credits may need roughly three months, variable income can need three to 24 months, refinance conduct can need three to 12 months and self-employed evidence may span one or two financial years. Start early, but do not collect everything so far in advance that it must be obtained again before approval or settlement.

THE COMPLETE PROCESS

A good refinance is designed before the credit enquiry is created.

The process below separates investigation from application. That reduces unnecessary enquiries and helps ensure the lender is chosen for the complete file rather than the rate alone.

STEP 1

Define the problem

Write the objective in one sentence: lower total interest, improve cash flow, add an offset, end cross-collateralisation, release a defined amount of equity, consolidate debts or prepare for another transaction.

STEP 2

Audit the current loan

Record balance, limit, rate, remaining term, repayment type, fixed expiry, break cost, offset/redraw, fees, security links, guarantees and current lender pricing.

STEP 3

Request a reprice or internal option

Test whether the existing lender can improve the rate or product without a full move. Keep the result in writing where possible and compare it on the same assumptions.

STEP 4

Map the policy issues

Identify income type, serviceability sensitivities, conduct, LVR, property type, cash-out, borrower changes, exit strategy and evidence before lenders are shortlisted.

STEP 5

Model the structure

Set the proposed loan amount, remaining term, splits, repayment type, offsets, additional lending and security arrangement. Compare same-term and stress scenarios.

STEP 6

Compare realistic options

Use current rates and fees only after filtering for the broad scenario, then verify the product and policy. Do not treat the lowest row in a public table as the recommendation.

STEP 7

Prepare one complete application

Collect the evidence, reconcile inconsistencies, explain unusual items and confirm the purpose. A single well-selected application is usually better than several speculative ones.

STEP 8

Valuation and credit assessment

The lender verifies value, serviceability, conduct, property and documentation. Conditions may require updated evidence, debt closure, reduced limits or a revised loan amount.

STEP 9

Documents and discharge

Review the formal loan documents, return them correctly, arrange insurance where required and submit the old lender’s discharge authority early enough for settlement coordination.

STEP 10

Settlement and post-settlement check

Confirm the old loan is closed, payout is correct, splits and offsets are linked, salary and direct debits are redirected, consolidated facilities are closed and the first repayment is scheduled.

How long does refinancing take?

There is no reliable universal timeframe. A clean like-for-like file with digital valuation and complete documents can progress quickly; self-employed income, cash-out, property exceptions, borrower changes, manual valuations or discharge delays can add time. The correct starting point is the required settlement date and the slowest known dependency, not a generic promise.

Do not sign a discharge authority merely to create urgency. The replacement loan, costs and conditions should be sufficiently clear before the current lender is instructed to close the loan.

POLICY IN PRACTICE

Twelve refinance scenarios showing why the same facts can produce different lender answers.

These examples show how common refinance situations can play out differently. They are designed to help you prepare—not to confirm eligibility, exact capacity or approval likelihood.

Permanent PAYG borrower seeking a lower rate

Clean rate-only refinance with no additional lending.

Facts

Stable full-time employment, mortgage paid on time, 72% estimated LVR, principal-and-interest loan and no change to borrowers or security.

Why outcomes still differ

One lender may produce the sharpest price but a weaker valuation. Another may recognise the same income but use a higher expense benchmark. A streamlined pathway may exist only if the new repayment is lower and the conduct evidence meets its rules.

Preparation

Obtain current lender pricing, verify the accepted value range, compare the same remaining term and shortlist only products that fit the loan amount, LVR and required features.

Borrower on probation after moving to a better-paid role

Same occupation, new employer, three months into a six-month probation period.

Facts

The applicant has worked in the profession for eight years but recently changed employer. The new salary is higher and permanent employment is documented apart from probation.

Possible policy paths

One policy may require probation to be completed. Another may consider uninterrupted same-industry history and the permanent contract. A score-led path may accept or decline without the same scope for a manual explanation.

Preparation

Provide the employment contract, commencement date, prior-role evidence and a clean explanation of continuity. Compare “apply now” with “wait until probation ends” rather than assuming one is always better.

Casual employee with reliable hours but variable payslips

Eighteen months in the role with seasonal peaks.

Facts

Hours are broadly consistent across the year, but holiday periods create higher payslips. The borrower has clean conduct and wants a like-for-like refinance.

Why usable income changes

A lender may average a longer period, rely on year-to-date income, use a conservative annualisation or require a minimum tenure. The highest recent payslips may not be treated as sustainable.

Preparation

Provide enough history to show the full cycle, not only peak weeks. Explain continuity and compare the application using a conservative income figure before price is prioritised.

Base salary plus commission after a strong year

Latest commission is materially above the prior year.

Facts

The base salary covers most commitments, but the requested refinance and small equity release depend partly on commission income.

Possible policy paths

One model may use a two-year average; another may use a percentage of the lower period; another may accept recent year-to-date evidence with a cap. A strong latest year is not automatically used in full.

Preparation

Separate base and variable income, provide two years plus current year-to-date evidence, explain the remuneration plan and test whether the transaction remains workable under a lower recognised commission amount.

Self-employed borrower with one strong latest year

Profit recovered after a weaker prior year.

Facts

The business has traded for several years. The latest tax year is strong, the prior year was affected by a temporary disruption, and current BAS supports the recovery.

Why outcomes diverge

A latest-year pathway may recognise more income; a two-year average may reduce it; a lower-of or declining-trend rule may be conservative. The reason for the prior weakness and current evidence become decisive.

Preparation

Prepare complete latest financials, BAS or management accounts, bank conduct and a factual explanation of the disruption. Use a lender whose evidence period fits the file rather than trying to argue every lender into the same result.

Company owner with depreciation, director wages and business debt

Several apparent add-backs but a vehicle facility remains.

Facts

The company pays the applicant a wage, reports profit after depreciation and interest, and has a commercial vehicle loan that will not be refinanced.

Why add-backs do not equal income

Director salary may be added back to profit only if it is not double counted. Depreciation may be accepted or capped. Interest may be added back only where the related debt changes, while the retained vehicle commitment still reduces servicing.

Preparation

Reconcile wages, profit, depreciation and every business debt. Provide a clear related-entity and liability schedule so the assessment uses each income and commitment once.

Applicant on parental leave with a confirmed return date

Short unpaid period before returning part-time.

Facts

The employer confirms the return date and reduced hours. Paid leave ends before the return, but savings can cover the temporary shortfall.

Possible policy paths

Some lenders may use confirmed return-to-work income and test the leave-period shortfall; others may focus on current income or require a different return horizon. Childcare and dependant costs also change the serviceability picture.

Preparation

Document the return income and hours, paid-leave schedule, savings buffer and revised household expenses. Do not model the refinance using the old full-time salary if the confirmed return is part-time.

Equity release for a substantial renovation

Strong equity, but the scope may cross into construction-style finance.

Facts

The borrower wants to refinance the existing loan and release funds for structural work, with staged payments to a builder.

Why transaction classification matters

One policy may allow documented cash-out; another may require controlled progress payments, a fixed-price contract and an on-completion valuation. The current value and proposed completed value are different concepts.

Preparation

Finalise scope, quotes, contract, approvals and contingency. Decide whether the correct product is a cash-out refinance, renovation split or construction facility before choosing the lender.

Debt consolidation after repeated credit-card use

Clean mortgage, but revolving debts have remained near their limits.

Facts

The proposed refinance would repay several cards and a personal loan, materially reducing the minimum monthly outgoings.

Why lender and suitability outcomes differ

A lender may cap unsecured debt, require direct payout and closure, or decline because conduct shows continuing stress. Another path may consider the file at a higher price. Even if approved, a 25-year consolidation term can increase total interest.

Preparation

Collect statements and payout figures, close unused limits, separate the consolidated debt, set a shorter payoff target and address the budget behaviour that created the balances.

Investor releasing equity for another deposit

Multiple properties, interest-only debt and mixed redraw history.

Facts

The borrower has adequate equity but relies on rent and wants a new split for the next purchase. One existing loan has private redraw transactions.

Why outcomes diverge

Rental shading, negative-gearing treatment, sensitised existing debts, interest-only expiry and mixed-purpose tax records vary. A lender can accept the security but produce a weaker serviceability result.

Preparation

Build a property-by-property schedule, identify every loan purpose, obtain tax advice on mixed redraw, isolate the new deposit split and test the portfolio under principal-and-interest repayments.

Hardship arrangement completed ten months ago

Repayments have been current since the arrangement ended.

Facts

A temporary income shock led to a formal arrangement. The cause has ended, income is stable and recent conduct is clean.

Possible policy paths

Some mainstream or streamlined pathways may not be available because the hardship is recent. A manual or specialist path may examine cause, resolution, current obligations, LVR and recovery. Waiting can materially change the available evidence period.

Preparation

Obtain the credit report, arrangement and completion evidence, current statements and a concise explanation. Compare an immediate specialist option with a later mainstream review rather than focusing only on today’s rate.

Older borrower refinancing into a long new term

Low LVR, strong current income and retirement within the proposed term.

Facts

The refinance lowers the rate but extends the loan beyond expected retirement. The borrower has superannuation and plans to downsize later.

Why exit-strategy policy matters

One lender may accept a shorter term based on current income; another may consider a documented asset-sale or downsizing strategy; another may require retirement income to service the debt without asset sale.

Preparation

Model the loan at retirement, document superannuation and assets, use a realistic property and timing assumption, and avoid an exit strategy that would create hardship or depend on an uncertain windfall.

How to use these scenarios: identify the facts that resemble your position, then turn them into questions for a broker or lender. Do not convert a scenario into a claim that a particular lender will approve, recognise a specific income amount or lend a specific sum.

WHEN NOT TO REFINANCE

Sometimes the best refinance decision is to improve the file, reprice internally or wait.

Not refinancing is not the same as doing nothing. It can be a deliberate strategy while a fixed term, equity position, credit history, employment period or set of financials reaches a stronger point.

The current loan is already competitive

After realistic fees and features, the available saving may be too small to justify a move.

Break costs dominate the benefit

A fixed-rate break cost can make waiting until expiry stronger even when the future revert rate is unattractive.

The loan may be sold or repaid soon

A long break-even period is difficult to recover if the property or loan will not be retained.

The accepted value may trigger LMI or tighter policy

A small debt reduction, more time or a stronger valuation position may open materially better options later.

Income evidence is between stronger dates

Waiting for probation to end, a contract renewal, return from leave or completed self-employed financials can improve policy fit.

Recent conduct needs time to recover

Clean current repayments and reduced limits can be more useful than creating another credit enquiry immediately.

The refinance depends on stretching the term

If the only benefit comes from restarting a shorter loan at 30 years, compare a reprice, budget change or temporary term decision separately.

The purpose or tax structure is not ready

Investor equity release, borrower changes, separation and business use should be structured with appropriate legal or tax advice before the loan is lodged.

Financial hardship is the real issue

Contact the existing lender’s hardship team and a free financial counsellor. An expensive or rushed refinance can transfer the problem rather than solve it.

Useful alternatives while you wait

Ask the current lender to reprice or change products internally.
Reduce unused credit limits and close facilities that are no longer needed.
Keep all repayments on time and correct errors on the credit report.
Build equity through repayments or a planned lump-sum reduction.
Prepare the next set of self-employed financials or variable-income history.
Obtain the fixed-rate expiry and break-cost information early.
Separate mixed-purpose debt and improve record keeping.
Set a future review date with the exact policy milestone required.

DETAILED REFINANCE FAQS

Questions borrowers commonly ask before changing home loans.

Each answer is intentionally general. A lender-specific rule or personal conclusion still requires current policy and a complete application.

What is home loan refinancing?

Refinancing replaces or restructures an existing home loan. It may involve a new lender paying out the old loan, or an internal refinance or product change with the existing lender. The purpose can be price, features, term, equity release, consolidation or a change in borrowers or security.

Is repricing the same as refinancing?

No. Repricing generally means the existing lender reduces the rate on the current loan without a full lender change. Refinancing usually involves a new credit decision and may involve new loan documents, valuation, mortgage registration and settlement. Repricing should often be tested before an external move.

How much lower must the new rate be before refinancing is worthwhile?

There is no universal rate gap. Loan balance, remaining term, switching costs, ongoing fees, offset value, break costs and expected holding period determine the result. Calculate the monthly net saving and break-even, then compare total interest using the same remaining term.

Does a perfect mortgage repayment history guarantee refinance approval?

No. Clean conduct is valuable, but a new lender still assesses current income, expenses, liabilities, serviceability, credit score, property, valuation, structure and purpose. Conduct is one approval gate rather than a substitute for the others.

Can I refinance if my income has fallen since the original loan?

Potentially, but the new lender will assess the income it can currently recognise. A lower balance, stronger equity, reduced debts, a co-borrower or a narrow alternative refinance pathway may help in some cases. The result cannot be inferred without a full assessment.

Can I refinance while on probation?

Potentially. Lenders differ on probation, permanent status, time in role and same-industry continuity. A borrower with a long occupational history and a documented permanent role may have different options from someone new to both the employer and occupation.

Can casual or contract income be used?

It may be usable where policy, history and evidence are satisfied. Lenders can differ on minimum tenure, remaining contract term, renewal history, average hours, year-to-date income and how seasonal or variable earnings are annualised.

How are overtime, bonus and commission assessed?

They are commonly treated as variable income. The lender may use a percentage, average, lower-of periods, current year-to-date result or an occupation-specific rule. A strong recent period may not be used in full if the longer history is lower or inconsistent.

Can I refinance while on parental leave?

Potentially. The key evidence can include the return-to-work date, hours and income, paid and unpaid leave, dependants, childcare costs and resources covering any temporary shortfall. Policies differ on whether and how confirmed return income is used.

Can self-employed borrowers refinance using one year of financials?

Some policies provide a latest-year or simplified path, while others require two years or more evidence. Trading history, profit trend, BAS, current bank conduct, LVR, loan purpose, entity structure and the quality of the financials still matter.

What self-employed add-backs can be used?

Potential items can include depreciation, interest on debt being refinanced, director wages already deducted from profit, some one-off expenses and certain discretionary contributions. Acceptance, caps and evidence vary, and no item should be added back automatically or counted twice.

What is a streamlined refinance?

It is a lender-specific alternative assessment for a narrow type of refinance, often involving the same borrowers and security, clean conduct, moderate LVR, little or no additional lending and a lower or comparable new repayment. It is not a universal product and does not guarantee approval.

Can I refinance if I recently used hardship assistance?

Potentially, but recent hardship can restrict mainstream or streamlined options. The cause, current contractual repayment, time since the arrangement, recent conduct, LVR and evidence of recovery may be relevant. If repayments remain difficult, hardship support should be addressed before a new application.

Does refinancing affect my credit score?

Using a calculator or obtaining general advice does not itself create a lender credit enquiry. A formal application usually involves credit checks. Multiple speculative applications can add enquiries and may complicate assessment, so lenders should be shortlisted before lodging.

How much equity do I need to refinance?

There is no single equity requirement for every lender or product. Lower LVR generally broadens options and can improve pricing. Above 80% LVR, mortgage insurance or other costs may apply and the range can narrow. The lender’s accepted valuation determines the actual LVR.

Can I refinance above 80% LVR?

Potentially, depending on the lender, property, borrower, loan purpose, mortgage-insurance position and serviceability. Existing LMI does not simply transfer to the new lender, so the cost can make repricing or waiting more attractive.

Can I refinance and release equity at the same time?

Potentially. The proposed value, resulting LVR, serviceability, amount, purpose and evidence all matter. Larger, open-ended or higher-LVR releases can require stronger evidence or a different product and assessment path.

Can refinancing be used to consolidate debts?

It can, subject to policy and suitability. The new lender may require direct payout and closure. A lower monthly repayment can still create higher total interest if short-term debt is extended over a mortgage term, so a separate split and faster payoff plan are often important.

Should I refinance a fixed-rate loan before expiry?

Obtain a current break-cost estimate first. Compare moving now, waiting until expiry and arranging the next loan before the revert rate applies. Break costs can change, so a historical or rough estimate is not enough for the final decision.

Does refinancing reset the loan to 30 years?

Not automatically. The new term is a structural choice subject to lender policy. Compare the new loan using the remaining term first. If a longer term is chosen for cash flow, show the extra total interest and set a repayment strategy.

Is an offset account always worth paying for?

No. Its value depends on the balance likely to remain in the offset, the rate difference, account and package fees, and how consistently the borrower uses it. A useful offset can outweigh a small rate premium; an empty offset may not justify the cost.

How is rental income treated when an investor refinances?

Lenders may use only part of gross rent and can rely on different evidence. Property expenses, negative gearing, existing loan repayments, interest-only expiry and other portfolio debts also affect the serviceability result.

Does refinancing change the tax deductibility of investment debt?

Tax treatment generally follows the use of borrowed funds. Refinancing the same investment debt may preserve its character, but additional borrowing for private use can require apportionment. Mixed redraw and loan purposes should be reviewed with a tax adviser.

Can I remove a borrower or former partner during a refinance?

Potentially, but the remaining borrower usually needs to qualify for the new debt and the ownership or title change may require legal, tax and settlement work. A relationship-property agreement does not itself force a lender to release a borrower.

Can I add a spouse, trust or company to the new loan?

Potentially, but changing borrower or entity structure is not like-for-like. Income, liabilities, beneficial ownership, guarantees, title and tax consequences may all require full assessment and professional advice.

Can an older borrower refinance into a new long term?

Potentially, where the repayment position and any required exit strategy are credible. Lenders may consider retirement income, superannuation, assets, downsizing and age at maturity differently. The strategy should not depend on hardship or an unrealistic property value.

How long does a refinance take?

Timing depends on document readiness, valuation, lender assessment, loan complexity, formal documents, discharge processing and settlement coordination. A clean like-for-like refinance can be faster than self-employed, cash-out, property-exception or borrower-change transactions.

What happens to my offset and direct debits at settlement?

They do not automatically transfer. Confirm when the old offset stops reducing interest, move salary and bill payments, link the new offset to the correct split, keep enough funds in both systems during transition and verify the first new repayment.

Should I choose the lowest advertised refinance rate?

Not without checking eligibility, comparison rate, fees, LVR tier, loan amount, features, policy and remaining term. The lowest public rate can be attached to a narrow product or may not provide the best total outcome.

When should I ask my current lender to reprice?

Before lodging an external refinance is often sensible, especially when the existing structure still suits. Compare the repriced rate and product against realistic external options, then decide whether the remaining gap justifies the move.

REFINANCE GLOSSARY

Key terms used in refinance policy and loan comparisons.

Assessment rate

The interest rate used to test serviceability, which is usually higher than the proposed product rate.

Break cost

A possible cost for ending or changing a fixed-rate loan before its fixed period expires.

Cash-out

Additional borrowing above the amount needed to pay out the existing loan and approved costs.

Comparison rate

A standardised rate including certain fees and assumptions. It may not reflect the borrower’s actual loan amount, term or feature use.

Comprehensive credit reporting

Credit-report information that can include current credit obligations and repayment history, not only adverse events.

Cross-collateralisation

More than one property securing the same lending structure, which can affect future releases, sales and refinancing.

Discharge authority

The instruction that starts the current lender’s process to release its mortgage and accept payout.

Equity

The difference between property value and debt, before selling costs and subject to the lender’s accepted value.

Exit strategy

A credible plan for repaying debt where the proposed term extends beyond sustainable income or retirement.

Interest-only

A repayment arrangement where scheduled payments do not reduce principal during the interest-only period.

Like-for-like refinance

A refinance with substantially the same borrowers, security, balance, purpose and repayment structure.

LMI

Lenders mortgage insurance, generally protecting the lender rather than the borrower when higher-LVR lending is approved.

LVR

Loan-to-value ratio: proposed loan amount divided by the lender’s accepted property value.

Offset account

A linked transaction account whose balance reduces the loan balance on which interest is calculated, subject to product rules.

Repricing

A rate change offered by the existing lender without a full external refinance.

Serviceability

The lender’s assessment of whether recognised income can support sensitised debts, expenses and the proposed loan.

Streamlined refinance

A lender-specific alternative assessment available only when a narrow set of transaction and conduct rules is met.

Usable equity

The amount potentially available after applying an accepted value, maximum LVR, existing debt, serviceability and purpose rules.

ABOUT THIS GUIDE

Where the information comes from—and how to use it.

This page combines official Australian information with a broad, anonymised comparison of lender policy. The aim is to show the real questions that can change a refinance answer without publishing individual lender rules or suggesting that a general range proves your eligibility.

Why the policy detail is included

Rate Challenge compared around 50 lender policy sets across more than 120 areas, including income, debts, repayment conduct, property, cash-out, investor lending and loan structure. Thousands of individual policy points were then translated into plain English and rounded so the guide explains the practical differences rather than reproducing a lender rulebook.

The ranges show what may be possible at the flexible and conservative ends of the market. No single lender necessarily offers every point in a range, and the applicable setting can change with the product, LVR, documentation, credit profile, property and date.

What this guide cannot tell you

It cannot calculate your exact borrowing capacity, tell you which lender will approve the application or confirm that a particular policy applies to you. Those answers require complete borrower information, current lender calculators and a current policy check.

Products, pricing, insurer settings and lender rules can change. Use this guide to prepare the right questions, then confirm the current details before acting.

AUTHOR & REVIEWER

David Warburton — Mortgage & Finance Broker

David combines commercial-banking experience, mortgage broking and detailed lender-policy comparison to explain how a refinance moves from headline rate to a workable application. The aim of this guide is not to push every borrower toward a lender change. It is to make the policy, evidence, cost and structural trade-offs understandable before an application is lodged.

General information and important limits: this guide does not take your objectives, financial situation or needs into account. It is not an offer of credit and does not constitute personal credit, financial, tax or legal advice. Lender policies and pricing change, and every refinance remains subject to current assessment, responsible-lending obligations, valuation, documentation and individual circumstances. Obtain appropriate professional advice before changing ownership, tax, investment or business structures.
