7 Common Home Loan Mistakes Australians Make (and How to Avoid Them)

4 August 2026 7 min readPublished by Asset Connect Australia

Mistake 1: applying with the wrong lender first

Every formal loan application leaves an enquiry on your credit file. Apply with a lender whose credit policy does not suit your situation — self-employed income, a small deposit, casual employment — and you risk a decline that makes the next lender look harder at you. Order matters, and it is exactly what a licensed broker is paid to get right.

Mistake 2: borrowing the maximum just because you can

A lender approving an amount does not make it a comfortable amount. Repayments are assessed at a buffered rate, but life is not: rates move, incomes change, and families grow. Borrowing to the absolute ceiling leaves no room for any of it. A good professional will pressure-test the number against your actual life, not just the lender's calculator.

Mistake 3: changing your finances mid-application

New car on finance two weeks before settlement, a job change during assessment, a few buy-now-pay-later accounts opened for the new house — each of these can change a lender's decision after approval. Until the loan settles, the safest move is to keep your finances boring.

Mistake 4: judging a loan on the headline rate alone

The advertised rate is the start of the story, not the end. Fees, offset account costs, revert rates after a fixed period, and how the lender treats extra repayments all change what a loan actually costs. Two loans with the same headline rate can differ by thousands over a few years. Comparison rates help, but a licensed broker can read the fine print in the context of your plans.

Mistake 5: forgetting the upfront costs

Stamp duty, lenders mortgage insurance, conveyancing, building and pest inspections, moving costs — buyers regularly underestimate these by tens of thousands. Knowing the true cash-to-complete figure before you make an offer prevents the scramble that derails settlements.

Mistake 6: missing grants and concessions you qualify for

First home buyer grants, stamp duty concessions, and low-deposit schemes differ by state and change often. Buyers who go it alone routinely miss entitlements worth thousands simply because nobody told them to ask. Professionals who work in this space every day know what is currently available and who qualifies.

Mistake 7: setting and forgetting for a decade

The loan that suited you at settlement is rarely the sharpest loan available five years later. Lenders count on inertia — it is why loyal customers so often pay more than new ones. A periodic review is not disloyalty; it is basic financial hygiene.

Why a professional is worth the conversation

None of these mistakes come from carelessness — they come from doing something once that professionals do every day. A licensed mortgage broker must act in your best interests by law, is typically paid by the lender rather than by you, and sees hundreds of applications a year, so they know where the traps are before you step in them.
