Between the state and federal governments there has never been more support for building a new home in WA, and almost none of it applies to buying established. Here is what is available right now.
A $10,000 grant for first home buyers who build or buy a brand-new home. It does not apply to established homes at all. The property cap was lifted to $800,000 in the 2026–27 state budget, and grant eligibility is now separate from the stamp duty concessions.
From 7 May 2026, first home buyers pay no stamp duty on vacant land up to $450,000, with concessional rates up to $550,000. When you build, duty is only ever assessed on the land, not the house, so the government puts the combined saving at up to $25,390 for a land-and-build.
WA’s own low-deposit lender: get into a new build with a deposit as low as 2% and no lenders mortgage insurance, then refinance to a mainstream bank when you are ready. The 2026–27 budget added a further $375 million for affordable Keystart homes.
Buy or build your first home with a 5% deposit and no lenders mortgage insurance, the federal government guarantees the rest to the lender. Since late 2025 there are no income caps and places are no longer limited.
In the Albanese Government’s 2026–27 budget, Treasurer Jim Chalmers announced that from 1 July 2027, negative gearing will be restricted to newly built properties. Investors buying established homes will no longer be able to offset rental losses against their personal taxable income, while those who build (or buy new) keep the full benefit.
The capital gains tax discount is changing at the same time, moving from the blanket 50% discount towards an indexation model, with new housing supply treated most favourably.
In short: the tax breaks now go to people who add a new home to the supply, not to people bidding on existing ones. (The changes were announced in the budget and still need to pass parliament.)
