First home incentive estimator
Estimate the WA First Home Owner Grant, your stamp duty saving and the deposit gap on a new build in one place. WA is the only state where a building broker can show you these stacked. Figures use the WA first home owner rate in force now and are indicative. The announced 2026-27 budget increase is not yet legislated. Verify current as at June 2026.

Map your first home plan →The first home incentive estimator stacks every WA first home support on a new build. The Property Plug tool combines the $10,000 First Home Owner Grant, the stamp duty saving versus the general rate, and your deposit gap at a 5%, 10% or 20% target into one benefit figure. It is general information for 2025-26, not credit or tax advice.
What a WA first home buyer can draw on in 2026
No single program decides whether you can buy your first home. It is the stack. A grant, a duty saving and a low-deposit scheme together can move a build from out of reach to achievable. Here is the full set for a new build.
| Support | What it gives | 2025-26 cap |
|---|---|---|
| First Home Owner Grant | $10,000 cash toward a new build | Property to $800,000 |
| Stamp duty exemption | No duty on a home | Up to $500,000 |
| Stamp duty concession | Reduced duty | $500,001 to $700,000 |
| First Home Guarantee | 5% deposit, no LMI | Eligibility and price caps |
| Keystart | Low-deposit WA lending, no LMI | Income and price caps |
| Help to Buy | Shared equity, smaller loan | Rolling out, caps apply |

A $560,000 new build, first home buyer
On a $560,000 new build, an eligible first home buyer collects the $10,000 grant and pays a concessional stamp duty figure well below the roughly $20,000 an investor would pay on the general rate. Stacked, the grant plus the duty saving can total over $20,000 of benefit before a dollar of loan cost. Against a 5% deposit target of $28,000, that benefit closes most of the gap.
- Grant: $10,000 toward the build.
- Duty saving: the gap between the general rate and the first home concessional rate.
- Deposit target: 5%, 10% or 20% of the build value, your choice in the tool.
- Gap: what is left to save once savings and the grant are counted.
Building beats established for the grant
The $10,000 grant and the lower duty on a separate land-and-build contract both reward building new over buying established. That is structural, not a promotion. It is also why a building broker is the right person to map your first home: we line up the design, the block and the finance so the supports actually land, rather than leaving you to chase each program alone.

What incentives does this estimator combine?
It stacks the $10,000 First Home Owner Grant for new builds (up to the $800,000 cap), the WA first home stamp duty saving versus the general rate, and your deposit gap at a 5%, 10% or 20% target. It gives one combined first home benefit figure plus the deposit position, which most single-purpose calculators do not.
Do I get the $10,000 grant on an established home?
No. The WA First Home Owner Grant applies only to new builds, including building a new home or buying a brand-new one that has not been lived in. This is a core reason building can beat buying established for a first home buyer, and the estimator reflects it.
Can I use the grant as part of my deposit?
In practice the grant is usually paid at settlement or first progress draw on a new build, so it reduces the loan you need rather than the cash you must save first. Lenders still want to see genuine savings. The estimator counts the grant toward your funds to show the realistic gap.
What about the First Home Guarantee, Keystart and Help to Buy?
They sit alongside the grant. The First Home Guarantee removes LMI at a 5% deposit, Keystart offers low-deposit WA lending with no LMI, and Help to Buy is a shared-equity scheme rolling out that can cut the loan you need. We work out which you qualify for on a call, since eligibility depends on income and price caps.
