What Is LMI? Lenders Mortgage Insurance Explained

🛡️ What LMI actually is🔗

Lenders Mortgage Insurance is a policy the lender takes out, that you pay for, to cover their potential loss if you default on the loan and the property doesn't sell for enough to cover the remaining balance. The name causes most of the confusion: it sounds like it protects you, the borrower, but it exists entirely to protect the bank.

It's required because a smaller deposit means a smaller buffer for the lender if property prices fall, so they pass the cost of insuring against that risk on to you.

📏 When you actually need it🔗

LMI is triggered by your loan-to-value ratio (LVR), the loan amount divided by the property's value. Once your deposit drops below 20% (an LVR above 80%), most lenders require LMI. Above roughly 95% LVR (a deposit under 5%), very few lenders will approve the loan at all, with or without LMI.

It's not just a first-purchase issue either. If you're refinancing your home loan and your LVR has crept above 80% since you bought, whether from a smaller property value or a larger loan balance, LMI can apply again with the new lender, sometimes wiping out the entire rate saving you were chasing.

🧮 How the cost is calculated🔗

LMI is priced as a percentage of your loan amount, and that percentage rises steeply, not evenly, as your LVR climbs. A borrower at around 85% LVR might pay somewhere near 1% of the loan amount, while a borrower at 95% LVR can pay 3-4% or more. The jump between bands is sharp: a small increase in LVR near the top end can meaningfully increase the premium, since the insurer's risk of a shortfall rises quickly once there's almost no equity buffer left.

Want an actual number rather than a general rule? Our LMI Calculator estimates your premium based on your own property value and deposit, and shows how much bigger your deposit would need to be to avoid it altogether.

In some states, stamp duty also applies to the LMI premium itself, on top of the premium, a detail worth checking with your lender or broker since it isn't always included in a quoted estimate. That's on top of the stamp duty owed on the property itself, our Stamp Duty Calculator will give you that number for your state and price.

⚖️ Who it actually protects🔗

This is the single most common misunderstanding: paying LMI doesn't protect you from anything. If the insurer pays out the lender after a default, the insurer can, and often does, still pursue you directly for the shortfall.

🏢 Who actually provides LMI, and why you can't shop around for it🔗

🎯 The essential: The lender chooses the insurer, not you, and there are really only two major providers in the entire Australian market.

Unlike car or home insurance, you don't get to compare LMI providers and pick one, your lender selects the insurer and effectively passes the premium on to you as a condition of the loan. It's also a genuinely concentrated market: Helia (formerly Genworth, Australia's original LMI provider since 1965) and QBE's mortgage insurance arm are the two main players, with Helia alone holding close to half the market by premium volume. Most major banks self-insure a portion of their low-deposit lending too, rather than using an external insurer for every loan, which is part of why the exact premium and provider can vary between lenders for what looks like an identical loan.

The practical implication is that "shopping around" for a cheaper LMI premium isn't really an option the way it is for most insurance, the premium is effectively set by whichever insurer your specific lender uses at your specific LVR band. What you can influence is the LVR itself, and which lender you borrow from in the first place, since different lenders' arrangements with their insurer can produce a genuinely different quoted premium for the same deposit and property value.

🪜 Ways to avoid or reduce it🔗

• Save a 20% deposit, the most straightforward way to avoid it entirely.
• Use a guarantor, whose equity can cover the gap that would otherwise trigger LMI.
• Check eligibility for the Home Guarantee Scheme, which lets eligible first home buyers purchase with a 5% deposit without paying LMI at all, the government guarantees the gap instead. See our First Home Guarantee guide.
• Ask about lender-specific waivers, some lenders offer reduced or waived LMI for certain professions or a slightly higher deposit band, worth asking a broker about directly.
