Buying your first home: how a home loan works

A home loan lets you buy a property with a deposit plus borrowed funds, repaid with interest over an agreed term of commonly 25 to 30 years. As a first home buyer your focus is usually the deposit you need, the rate you can secure, and the upfront help available. The property is used as security, so the lender can recover the debt if repayments stop.

Deposits, LVR and Lenders Mortgage Insurance

Your deposit sets your loan-to-value ratio (LVR). A 20% deposit gives an 80% LVR, the level at or below which most lenders do not charge Lenders Mortgage Insurance (LMI). Borrow more than 80% of the value, with a deposit under 20%, and LMI is usually added, though several government schemes can reduce or remove it. The smaller your LVR, the lower the risk to the lender, which can mean a sharper rate.

Government schemes for first home buyers

First home buyers may be able to buy with a 5% deposit and no LMI through the Australian Government 5% Deposit Scheme (the First Home Guarantee), which since 1 October 2025 has no limit on places and no income cap, though property price caps apply by location. Since 5 December 2025, the Help to Buy shared equity scheme also lets eligible buyers purchase with a 2% deposit while the government takes a share of the property. They can also save a deposit faster inside super via the First Home Super Saver scheme, or access state and territory stamp-duty concessions and grants. The rules change, and Housing Australia, the ATO and state revenue offices publish the current versions.

How first home buyer loans compare

The comparison rate sits alongside the headline rate, and features such as redraw and extra repayments matter for getting ahead early. Low-deposit options matter most here. Loans can be compared side by side, and the full market is on the home loans hub.
