What’s the minimum deposit required to buy a house in Australia?
Most lenders (including the big four banks) will accept a minimum deposit of 5% of the property’s value, if you pay for lender’s mortgage insurance (LMI) or are eligible to use the First Home Guarantee (FHG) scheme.
In practical terms, you would need a minimum deposit of $30,000 to buy a $600,000 home and borrow $570,000 from the bank.
Here’s an overview of the common house deposit amounts and when they typically apply:
- 20% deposit: You generally need a deposit of at least 20% of the property’s value to avoid LMI if you don’t otherwise qualify for an exemption. This means a maximum loan-to-value ratio (LVR) of 80%. Lenders usually consider loans with an LVR over 80% of the property value to be a higher risk.
- 10% deposit: Some lenders may require a minimum 10% deposit with LMI. You’ll need a strong application for this type of loan, which means having a good credit score, a steady income and solid employment history.
- 5% deposit: A 5% deposit is the minimum for a lot of lenders in most situations (with LMI added to your loan). It’s also the minimum deposit needed for the more widely available government schemes, such as the First Home Guarantee (FHBG) and the Regional First Home Buyer Guarantee (RFHBG). These schemes allow you to buy a home with a 5% deposit and avoid LMI.
- 2% minimum deposit: If you qualify, you may be able to buy a home with as little as a 2% deposit through the Family Home Guarantee (FHG), and avoid paying LMI. However, this scheme is only available to single parents who meet specific eligibility criteria.
- 0% deposit: It is possible to buy a property using the equity in your home without needing a deposit. Existing homeowners often access their equity for various reasons, such as purchasing a second home or an investment property.

BIG NEWS!
The Federal Government expanded the First Home Guarantee scheme on 1 October 2025. Under the new rules, any first home buyer can get a home loan with as little as a 5% deposit, without paying LMI or needing a guarantor. The expansion also removes income caps, introduces unlimited places, and raises the property value caps significantly.
Another option is rent-to-own homes, which typically require a smaller upfront amount, but this can end up being more expensive in the long run due to the additional fees charged.
