How does the 5% deposit First Home Guarantee work?

Under the First Home Guarantee, Housing Australia guarantees up to fifteen per cent of the property value to a participating lender, so you can buy with a five per cent deposit and pay no lenders mortgage insurance. You still borrow ninety-five per cent and still need to service the loan; what you save is the LMI premium, which on a $700,000 purchase at 95 per cent can be $25,000 or more.

From 1 October 2025 the scheme was expanded: the income caps were removed, the annual place limits were removed, and the price caps were lifted (for example $1.5 million in Sydney and $950,000 in Melbourne). You need to be a first home buyer (or not have owned property in the last ten years), an Australian citizen or permanent resident, and live in the home.

The catch is that a five per cent deposit still has to cover stamp duty and costs unless a concession applies, and at 95 per cent LVR your borrowing power, not your deposit, is usually the binding constraint. The check below runs both.
