The 5% Scheme, Help to Buy, and what you can actually combine.
Two federal home-buying schemes that look like they do the same thing. Most people I've talked to assume they stack. They don't, and the choice is worth tens of thousands of dollars.
The 5% Deposit Scheme, after 1 October 2025
For eligible first home buyers: 5% deposit, no Lenders Mortgage Insurance, nationwide. The federal government removed income caps and place limits.1 You apply through a participating lender; the government acts as guarantor for the missing 15%.
- Waives the LMI premium (often five figures on a sub-20% deposit).
- On a $700,000 home, that's a $35,000 deposit instead of the $140,000 a standard 20% loan asks for.
- Available in every capital city and growth corridor, subject to property price caps.
Help to Buy, opened 5 December 2025
In participating states and territories, the federal government takes a shared-equity stake of up to 40%. You contribute as little as 2% deposit. You make repayments on the share you own; the government's share sits behind it.3
- Lower deposit and lower loan than the 5% Scheme.
- You don't fully own the property. The government's share moves with the property's value.
- Conditions apply to what you can do with the property over time.
Why they don't combine
The two schemes are mutually exclusive.4 You pick one path:
- 5% Scheme: smaller deposit, full ownership, full mortgage, no LMI.
- Help to Buy: smallest deposit, partial ownership, smaller mortgage, government share of capital gain.
What does stack
- 5% Scheme + FHSS. Super contributions boost your deposit; the 5% Scheme handles the loan.6
- 5% Scheme + FHOG (new builds). Where state FHOG eligibility applies, both can sit together.
- FHOG + state stamp duty concession. State schemes generally stack with each other.
The bottom line
As a general rule, the 5% Scheme is the cleaner structure when you can save the deposit and want full ownership. Help to Buy can reduce the upfront cash and loan size, but you are accepting a shared-equity trade-off. Your state, income, property price, and lender approval still decide what is actually available.
