Buying in Caroline Springs as a first-home buyer — a real 5% vs 10% vs 20% example

1) Caroline Springs in 2025 — who this example fits

Caroline Springs (VIC 3023) is an established “west corridor” suburb that appeals to first-home buyers who want space, parks, schools and a family feel, without pushing into inner-suburb price tags. The challenge for many buyers in 2025 isn’t desire — it’s the maths: deposit size, scheme eligibility, LMI trade-offs, and repayments that still feel comfortable after stress testing.

Our Caroline Springs VIC 3023 Property Report 2025 covers the broader market picture. This case study zooms into the most common first-home buyer question we hear in the west: “Do we wait for 20%, buy at 10% with LMI, or try a 5% option using a scheme?”

If you want to run your own eligibility and scenario checks before you talk to a broker, start with the First Home Buyer Scheme Calculator, the Max Borrowing Calculator, and our plain-English First Home Buyer Guide.

2) Meet the couple and their starting point

Jess (27) works full-time in allied health and Callum (30) works in logistics. Their combined pre-tax income is around $156,000 per year. They rent in the western suburbs for $560 per week (about $2,430 per month).

They’ve saved $62,000 so far. They want a home in Caroline Springs around the $755,000 mark (give or take) — a realistic working budget for a family-style home in the area.

We model three practical paths (20%, 10% and 5%), then sanity-check what each one means for cash buffers, repayments and approval likelihood. For a quick “rate and savings” sense-check, we also reference the Rate Review Calculator and the Mortgage Repayment Calculator.

3) Scenario A — wait for a 20% deposit in Caroline Springs

First we model the classic “no LMI” approach: buy a $755,000 Caroline Springs home with a full 20% deposit.

Target budget for a 20% path

• Purchase price: $755,000.
• 20% deposit: $151,000.
• Allow roughly $30,000–$35,000 for Victorian transfer duty and buying costs (legals, inspections, adjustments) as a working figure.
• Keep at least $15,000 aside as a post-settlement buffer.

That puts a practical savings target around $196,000–$201,000. With $62,000 today, they would need to find another $134,000–$139,000 — often a multi-year journey depending on rent, living costs and income stability.

Loan size and repayments — 20% deposit

• Loan amount at 80% LVR: $604,000.
• Illustrative owner-occupied P&I rate: around 6.3% p.a. (indicative only).

At 6.3% over 30 years, repayments on $604,000 are roughly $3,740 per month. The upside is no LMI and often sharper pricing bands once you’re at (or under) 80% LVR.

The downside is time: you may spend years renting while aiming at a deposit target that can shift if prices rise. If you’re trying to decide “buy sooner vs wait longer”, it’s worth stress-testing both paths with the Rentvesting Calculator and reading the Rentvesting Guide.

4) Scenario B — buy sooner with 10% deposit + LMI

Next we test a 10% path. This is very common in west Melbourne first-home buyer journeys: it’s often achievable sooner, but includes LMI.

Working with $62,000 savings

At $755,000, a true 10% deposit is $75,500, so Jess and Callum aren’t quite there today. But many buyers don’t go from “not ready” to “fully ready” overnight — the real question is whether a short runway (e.g., 6–12 months) gets them to 10% plus costs plus buffer.

Loan size, LMI and repayments — 10% path

• Base loan at 90% LVR: $679,500.
• Indicative LMI: roughly 1.8% of base loan (varies widely), about $12,200.
• Assume LMI is capitalised: total loan roughly $691,700.

Using a slightly higher illustrative rate of 6.5% p.a. (indicative only) to reflect higher-LVR pricing, repayments on ~$691,700 are roughly $4,370 per month.

This path can work well if the budget stays comfortable after stress testing, and if there is still a meaningful cash buffer after settlement. It can also be a stepping stone: many buyers refinance once they build equity (see Refinance Caroline Springs).

5) Scenario C — buy with 5% deposit using a first-home buyer scheme

Now we test the option most first-home buyers ask about: buying with a 5% deposit while reducing or avoiding LMI via a government-backed guarantee scheme (where eligible).

The important nuance: schemes have rules (income caps, property price caps, participant limits, availability windows, lender participation), and they’re not a guaranteed entitlement. That’s why we always start with an eligibility sense-check using the First Home Buyer Scheme Calculator and then confirm details lender-by-lender.

What 5% looks like on $755,000

• 5% deposit: $37,750.
• Loan at 95% LVR: $717,250.

If a scheme reduces or removes LMI (subject to eligibility and lender policy), the big benefit is time: you may buy earlier with a smaller deposit. The trade-off is higher repayments and tighter serviceability tests.

Using an illustrative owner-occupied rate of 6.7% p.a. (indicative only) to reflect higher LVR bands, repayments on ~$717,250 are roughly $4,630 per month.

6) 5%, 10% and 20% deposits — side-by-side on a $755k Caroline Springs home

Below is a simplified snapshot to make the trade-offs clearer. Numbers are indicative only and rounded for readability.

*Savings targets assume a mix of deposit, buying costs and a modest buffer. **Repayments use rounded owner-occupied P&I rates between 6.3% and 6.7% p.a. over 30 years. Actual lender pricing, scheme eligibility, duty and LMI vary by lender, product and your exact situation.

In practice, we run these through multiple lenders, then sanity-check them against your real budget and buffers. For a quick “are we paying too much?” sense-check (now or later), use the Rate Review Calculator.

7) What they chose (and why)

After running the numbers and doing a scheme eligibility sense-check, Jess and Callum decided to aim for a 5% scheme pathway first — but only if repayments still left a comfortable buffer.

Their plan

• Use the First Home Buyer Scheme Calculator to narrow down realistic scheme pathways.
• Build savings from $62,000 to $85,000 over the next 6–10 months to increase buffers and improve approval odds.
• Get a broker-led pre-approval and keep the search inside a tight price bracket that suits repayments even if rates rise.

If the scheme path didn’t stack up at the time (availability/eligibility), their fallback was a short runway to a true 10% deposit instead of committing to a multi-year wait for 20%.

8) Next steps, calculators and Caroline Springs help
