Understanding PMI (LMI): the basics

Lenders Mortgage Insurance (LMI) is a mandatory cost for many Australian borrowers and protects the lender if you default. It’s typically required when your Loan to Value Ratio (LVR) exceeds 80% (deposit under 20%), allowing lenders to approve higher-risk loans.

Key points:

  • LVR threshold: Triggered when LVR > 80%.

  • One-time premium: Usually paid upfront and often added to your loan (meaning interest applies).

  • Cost varies: Based on loan size and LVR, the smaller your deposit, the higher the premium.

  • Not transferable: You may pay LMI again if you refinance above 80% LVR.

A HeyNest-connected broker can calculate LMI costs across lenders and help you factor this major expense into your strategy.

How to reduce your LMI cost

While often unavoidable for buyers with small deposits, smart planning can minimise or eliminate LMI.

Strategies:

  • Save 20%: The most reliable way to avoid LMI.

  • Guarantor loan: A family member’s equity can remove the need for LMI.

  • Government schemes: Programs like the First Home Guarantee allow eligible buyers to avoid LMI with smaller deposits.

  • Increase your deposit: Even 1% more can lower the premium.

  • Compare lenders: LMI fees differ widely.

HeyNest brokers compare lenders, LMI providers and schemes to structure your loan for the lowest possible LMI, often saving thousands.

Is paying LMI worth it?

Whether LMI is “worth it” depends on your finances and how quickly property prices are rising in your area.

Considerations:

  • Faster market entry: Enter the market sooner instead of waiting years to save 20%.

  • High upfront cost: Premiums can range from thousands to tens of thousands.

  • Cost of waiting: In fast-growing markets, delaying may cost more than LMI.

  • Emotional/financial relief: Owning sooner can offer stability and peace of mind.
