How Australian home loans work

Most Australian home loans run for 25–30 years, with 30 the most common. Rates come as variable, fixed (1–5 years), or split. The RBA cash rate — currently 4.10% (April 2026) — is the main driver of variable home loan rates. Offset accounts and redraw facilities let you reduce interest while keeping access to savings.

Typical Australian home loan rates (May 2026)

ProductTypical rate
Variable (owner-occupier, <60% LVR)~5.1–5.5%
Variable (owner-occupier, 80% LVR)~5.8–6.3%
3-year fixed~5.5–6.0%
Average new mortgage~5.50%

LVR, LMI and the 20% deposit

Loan-to-Value Ratio (LVR) is the loan as a share of the property value. Below 20% deposit (LVR above 80%), you typically pay Lenders Mortgage Insurance (LMI) — a one-off premium insuring the bank against your default. It can run into tens of thousands. The lowest rates are reserved for LVR of 60% or less.

Other costs to budget for

On top of your deposit and monthly repayment: stamp duty (state-based, often 4–5% of the property price, though first-home-buyer concessions apply), conveyancing, building and pest inspections, strata or body corporate fees for apartments, and council rates.

Worked example

Borrowing A$700,000 at 5.85% over 30 years gives a monthly repayment of about A$4,125. Total interest across the term is roughly A$785,000 — more than the loan itself. Adding A$200/month in extra repayments shortens the loan by about 4 years and saves ~A$140,000 in interest.

Frequently asked questions

How much can I borrow in Australia?
Banks assess income, expenses, deposit and a serviceability buffer (currently 3% above the loan rate). Typical borrowing capacity is 5–7× annual income for owner-occupiers.
Should I fix or go variable?
Fixed rates offer certainty for 1–5 years but limit extra repayments and offset use. Variable rates are flexible and historically tend to come out cheaper over long horizons.
What is an offset account?
A linked transaction account where every dollar reduces the interest charged on your home loan, while remaining fully accessible.
How does LMI work?
Lenders Mortgage Insurance is a one-off premium charged when your deposit is below 20%. It can usually be added to the loan rather than paid upfront.
