Buy before selling only when the peak debt and exit still work.
A bridging loan temporarily carries the existing debt and the new purchase. The decision depends on property values, sale proceeds, settlement timing, interest, buffer and a credible exit — not only whether the new home can be bought.
General information only. The rate assumption in the quick check is entered by the user because bridging pricing is lender- and scenario-specific and is not represented by the standard daily home-loan feed.
Compare the sequence before choosing bridging.
The best option depends on contract certainty, available accommodation, equity, income, market conditions and risk tolerance.
Sell first
Lowest overlap risk and clearer sale proceeds, but may require temporary accommodation or a longer settlement.
Use bridging finance
Buy before sale with one temporary peak-debt position and a planned reduction when the existing home settles.
Negotiate timing or alternatives
Long settlement, simultaneous settlement, deposit bond, family help or another temporary structure may reduce the need for a full bridge.
Estimate peak debt, sale proceeds and end debt.
This calculator is deliberately transparent: you enter the interest-rate assumption. Standard daily mortgage pricing is not a reliable proxy for a bridging facility.
Peak debt first, end debt after the sale.
Different lenders use different terminology and structures, but the financial logic remains the same.
Peak debt
The existing debt plus new purchase and costs, less available cash, before sale proceeds are applied.
Capitalised or serviced interest
Interest may be paid monthly or added to the facility within policy and LVR limits.
Sale proceeds
Net sale proceeds after selling costs and payout of existing debt reduce the bridge.
End debt
The intended long-term loan remaining after the existing property settles.
Bridge term
The facility normally has a short maximum period, creating real time pressure if the property does not sell.
Exit strategy
Sale is the usual exit, supported by a realistic price, marketing plan, time allowance and fallback options.
Bridging approval is driven by the exit and security position.
A strong income alone does not solve a weak sale plan or an over-optimistic property value.
Sale status
Not listed, listed, under contract and unconditional sale positions can be assessed differently.
Peak and residual LVR
Lenders can apply separate maximums before and after sale.
Servicing method
Some assess peak debt, some focus on end debt with conditions, and interest capitalisation rules vary.
Valuations
Both properties are commonly valued and the lender may adopt a more conservative figure.
Acceptable security
Location, marketability, property type and title can affect whether the bridge is available.
Term and extensions
The maximum bridging period and extension policy matter if the sale takes longer than expected.
Bridging becomes dangerous when optimistic assumptions stack together.
Stress-test at least one weaker sale and longer timing case before committing.
Sale-price shortfall
A lower sale price leaves a larger end debt and can breach the intended LVR.
Sale delay
Interest, insurance, rates and maintenance continue while the bridge remains open.
Two-property costs
The borrower can temporarily carry two sets of ownership and transaction costs.
Unconditional purchase
Auction or unconditional contracts remove a finance escape if approval, valuation or sale assumptions fail.
Renovation before sale
Spending on the current property can increase peak debt without guaranteeing a higher sale price.
No fallback plan
A bridge should include actions if the property is not sold by key dates, not merely hope for an extension.
The property sale is part of the credit application.
Prepare sale evidence and timing with the same discipline as income and loan documents.
Market appraisal
Use realistic evidence from local agents and comparable sales, not the price needed to make the transaction work.
Marketing timing
Allow for preparation, campaign, negotiation, contract conditions and settlement.
Selling costs
Agent, marketing, legal, discharge and property-preparation costs reduce net proceeds.
Settlement coordination
The conveyancer, sale agent, purchase contract and lender discharge/settlement teams need aligned dates.
Fallback price
Know the lowest sale outcome that still leaves an acceptable end debt.
Fallback accommodation or finance
Consider what happens if the purchase or sale timing changes before settlement.
A bridge may not be the right solution.
Buying first can feel convenient, but convenience should not override the financial and contractual risk.
Pause when the sale value is uncertain
Highly unusual property, weak market evidence or reliance on one optimistic appraisal can make the end debt unreliable.
Pause when the end debt is not comfortably serviceable
The transaction should still work after sale without relying on immediate refinance or an unsustainable term.
Pause when there is no timing buffer
A very short purchase settlement combined with an unlisted existing home can create valuation, approval and sale pressure.
Pause when every dollar is required
Interest, duplicated ownership costs, sale shortfall and unexpected repairs require a real cash or equity buffer.
Build the exit before making the purchase unconditional.
Map both properties
Current value/debt, new price/costs, sale price, cash and settlement dates.
Calculate peak and end debt
Include interest, fees, sale costs and conservative timing/value assumptions.
Match lender policy
Security, LVR, serviceability, capitalisation, term and sale status.
Obtain valuations and approval
Submit income, property, sale and contract evidence before committing where possible.
Coordinate purchase and sale
Manage settlement, discharge, sale proceeds and conversion to the end-debt facility.
What a bridging review commonly needs.
The lender may request additional sale and property evidence beyond a standard home-loan application.
Income and liabilities
Identity, income, expenses, debts, current loan statements and serviceability information.
Current property
Rates notice, title/security details, valuation access, estimated sale value and marketing status.
New purchase
Contract, purchase price, costs, settlement date and valuation access.
Sale evidence
Agent appraisals, listing agreement, campaign or sale contract where available.
Cash and costs
Available cash, deposit, purchase costs, selling costs and interest buffer.
Exit plan
Expected sale and settlement timing, target end debt and fallback actions if delayed.

Clear lender policy, clean execution and a plan that survives the real application.
David Warburton combines commercial-banking experience with mortgage broking and a broad lender panel. The aim is not to force a lender change or maximise debt. It is to explain the trade-offs, match the file to workable policy and keep the transaction moving from the first review through to settlement.
Questions to answer before buying first.
What is peak debt?
Peak debt is the temporary total borrowing before the existing property sale proceeds are applied.
What is end debt?
End debt is the intended long-term loan remaining after the existing property is sold and net proceeds reduce the bridge.
Do I make repayments during the bridge?
This depends on the lender and structure. Interest may be serviced or capitalised within approved limits. Other debts and property costs still need to be managed.
How long can a bridging loan run?
Terms are short and lender-specific. The sale and fallback plan should not rely on an extension being granted.
Does my current home need to be sold first?
Not necessarily, but the sale status affects lender policy and risk. A property under an unconditional sale contract is generally a stronger exit than an unlisted property.
Can bridging be used to build a new home?
Potentially, but construction timing, progressive draws and the sale of the existing home create a more complex structure requiring specialist policy.
How is the existing property valued?
The lender normally orders its own valuation and may use a value lower than an agent appraisal.
What if the property sells for less than expected?
The end debt increases. If the shortfall is material, extra cash, sale of another asset or a different lending outcome may be required.
Can I bridge if I am retired or downsizing?
Potentially. The end debt, sale equity, income, age/term strategy and lender policy must all be considered.
Does the daily home-loan rate feed show bridging rates?
No. Bridging facilities are specialised and scenario-specific. The page therefore uses a transparent user-entered rate assumption and requires lender confirmation.
Test the sale, timing and end debt before buying first.
A bridging review should show the peak debt, conservative sale proceeds, interest buffer and a credible fallback — not merely the purchase price.
