Top Strategies to Avoid First Home Buyer Mistakes

Most first home buyer mistakes happen before an offer is signed. The strongest move you can make is to confirm which schemes you qualify for, and what they cost you, before you fall for a property.

Upper Swan sits in the Swan Valley wine region, within the City of Swan. Whether you choose an established home or a new build changes which grants and concessions apply. Getting it right early keeps your purchase on track.

Which WA First Home Buyer Grants and Duty Concessions Apply?

In Western Australia, the first home owner grant (FHOG) is $10,000 and applies only to new homes. Stamp duty relief is separate and covers new homes, established homes and vacant land.

Since 7 May 2026, the first home owner rate of duty means no duty is payable on a home up to $600,000. A concessional rate applies between $600,001 and $800,000. For vacant land, no duty is payable up to $450,000, with a concession up to $550,000. One statewide threshold now applies, so the old Perth versus regional split no longer matters.

The duty concession follows the grant's eligibility rules even when no grant is payable. At least one applicant must be an Australian citizen or permanent resident. Neither you nor your spouse can have previously received the grant or the first home owner rate of duty in any jurisdiction. The trade-off is that the grant itself is not available for established homes, so a buyer choosing an established home gets duty relief only. Our first home buyer WA guide covers the detail.

Can You Buy With a 5% Deposit and Avoid LMI?

Yes, if you qualify for the Australian Government 5% Deposit Scheme, which lets eligible first home buyers buy with a 5% deposit without paying Lenders Mortgage Insurance (LMI). Housing Australia backs the lender for the portion of the loan between your deposit and 20% of the property value.

There are no income caps, but there are price caps. In Western Australia the cap is $850,000 for the capital city and regional centres category and $600,000 for other areas. The cap for a specific home depends on its suburb and postcode in Housing Australia's postcode search tool. Both the purchase price and the lender's assessed value must sit at or below it.

The main risk is occupancy. You must move in within six months of settlement and keep living there while the backing is active. If you don't, the lender may require you to pay LMI. Applications go through a participating lender only. Help to Buy is a separate scheme and cannot be combined with other government loan backing. Read more on the Home Guarantee Scheme.

Get Pre-Approval Before You Fall for a Property

Pre-approval tells you what a lender is prepared to offer before you commit to a contract. Without it, you risk bidding on a home your finances or your scheme can't support.

Consider a buyer who plans to use the 5% Deposit Scheme and signs a contract on a home priced just under the cap for its postcode. The lender's valuation then comes in above the cap, so the buyer no longer qualifies. The deposit is at risk and the buyer must scramble for another option.

The fix is to check the postcode cap first and speak with a lender before making an offer. A buyer who does this can negotiate, pick a home well inside the cap, or restructure the purchase with full knowledge. Start by understanding your borrowing capacity, then ask for pre-approval. Pre-approval is not a final loan approval, as the lender still values the property and reviews your circumstances.

First Home Super Saver Scheme: Time Your Release Carefully

The First Home Super Saver scheme lets you release eligible voluntary super contributions towards a first home, but only if you request a determination before ownership of any property transfers. Once settlement has happened, it is too late.

You can count up to $15,000 of voluntary contributions in a financial year, and up to $50,000 in total. The ATO states that release usually takes between 15 and 20 business days, so build that into your settlement timeline. The trade-off is that your money stays in super until released, and the assessable amount is included in your tax return, with tax withheld on release. Speak with your accountant about how this affects you.

Timing matters again after release. You generally need to sign a contract to buy or build within 12 months of requesting release, and tell the ATO within 90 days of signing. Consider a buyer who requests release, then delays house hunting past the deadline. The extra FHSS tax is 20% of the assessable released amount, on top of income tax. In an ATO illustration, a release of $26,100 with an assessable amount of $20,100 results in $4,020 of additional tax. The ATO can allow more time in some cases, so ask early rather than assuming.

Budget for Costs Beyond the Deposit

A realistic first home buyer budget covers more than the deposit. Duty, legal and conveyancing fees, inspections, valuation fees, mortgage registration and building insurance all sit on top, and Help to Buy does not cover them.

Your repayments need room too. Test your budget against a higher interest rate than today's, not just the one you are offered, and use our mortgage repayment calculator to see how repayments move. A lender will also assess your living costs and debts, so reduce credit card limits before applying.

If your deposit is under 20% and you are not using a government scheme, LMI may apply. It adds cost to the loan, though it can bring your purchase forward. Our local team on the Upper Swan mortgage broker page can walk you through which structure suits your goals.
