LMI protects the lender, not you, but you pay for it. Here's how the premium is calculated, when it's charged, and how to legitimately avoid it.

Who does LMI actually protect?

It exists because Australian lenders are legally required to hold extra capital against high-LVR loans (above 80%). LMI lets them outsource that capital requirement.

How much does LMI cost?

Critically, LMI is non-refundable and non-portable. If you refinance to a new lender 18 months later, you pay LMI all over again at the new lender: the premium doesn't transfer.

As of 10 July 2026, the cheapest owner-occupier variable rate Ratesniffers tracks for loans up to 80% LVR is 5.89% p.a., against 5.94% p.a. for the 80%-95% LVR band where LMI applies, a gap of just 5 basis points. The LMI premium itself, not a materially higher interest rate, is what makes borrowing above 80% LVR expensive.

How can I avoid paying LMI?

20% deposit + costs is the cleanest path. A family pledge / guarantor loan uses a parent's property equity to top up your deposit on paper. The Home Guarantee Scheme (FHBG / FHG / RFHBG) gives eligible buyers a no-LMI loan with 5% (FHBG) or 2% (FHG) deposit, and since 1 October 2025 the First Home Guarantee has no income caps or place limits, with raised property price caps. Some professional packages (medical, legal) waive LMI up to 90% LVR.

LMI is a one-off insurance premium that protects the LENDER if you default and the property sells for less than the loan balance. You pay the premium; you don't get any coverage from it. If your house is repossessed, the LMI insurer pays the lender's shortfall and then chases you for it. It exists because Australian lenders are legally required to hold extra capital against high-LVR loans (above 80%). LMI lets them outsource that capital requirement.

How much does LMI cost?

Premium scales with both LVR and loan size. Indicative ballpark for a $600K loan: 85% LVR ~$8K, 90% LVR ~$15K, 95% LVR ~$25K. Some lenders let you capitalise the premium into the loan (pay it off over the loan term) rather than upfront. Critically, LMI is non-refundable and non-portable. If you refinance to a new lender 18 months later, you pay LMI all over again at the new lender: the premium doesn't transfer.
