Lenders Mortgage Insurance (LMI) Explained: What It Costs and How to Avoid It

Lenders Mortgage Insurance catches many buyers off guard. You’re not the one who benefits from it, yet you’re the one who pays for it. Understanding LMI — what it costs, and how to avoid it — can save you tens of thousands of dollars before you even sign a contract.

What Is Lenders Mortgage Insurance?

LMI is an insurance policy that protects the lender — not you — if you default and the property sells for less than your outstanding loan balance. It applies any time you borrow more than 80% of a property’s value (LVR above 80%). The premium is a one-off cost, typically added (capitalised) onto your loan at settlement.

Despite the name, LMI provides you no personal cover or benefit. It exists purely to reduce the bank’s risk when lending at a high LVR. For first-home buyers, it’s often the cost of entry when a 20% deposit isn’t yet achievable. Before applying, it’s worth understanding how much deposit you actually need.

What Does LMI Cost? Real Examples on a $600k Property

LMI premiums are calculated by the insurer — most commonly Helia (formerly Genworth) or QBE — based on your LVR and loan size. Higher LVR means higher premium.

Example 1: $600,000 Property, 10% Deposit (LVR 90%)

Deposit: $60,000 | Loan: $540,000
Estimated LMI premium: approximately $10,000–$12,000
If capitalised, your loan becomes approximately $550,000–$552,000

Example 2: $600,000 Property, 5% Deposit (LVR 95%)

Deposit: $30,000 | Loan: $570,000
Estimated LMI premium: approximately $20,000–$23,000
If capitalised, your loan becomes approximately $590,000–$593,000

Moving from 10% to 5% deposit roughly doubles the LMI cost. These are estimates — exact premiums vary by lender and insurer. When we prepare your home loan assessment, we calculate your specific figure. A full home loan preparation guide helps you budget for all upfront costs, not just LMI.

Can You Capitalise LMI Into Your Loan?

Yes. Most lenders allow you to add the LMI premium to your loan balance at settlement rather than paying cash upfront. This reduces the cash you need on the day — but you’ll pay interest on that capitalised amount for the life of the loan. A $20,000 LMI premium capitalised into a 30-year loan at 6% costs closer to $43,000 in total.

LMI Refunds

LMI premiums are generally non-refundable. Some policies include a partial refund if the loan is repaid within the first year (roughly 40%) or second year (roughly 20%), but this varies. Don’t plan around a refund — in most cases, what you pay is permanent.

How to Avoid Paying LMI

Save a 20% Deposit

Bring your LVR to 80% or below, and LMI doesn’t apply. For many Sydney or Melbourne buyers, this takes time — but it’s the cleanest path.

First Home Guarantee (5% Deposit, No LMI)

The Federal Government’s First Home Guarantee allows eligible first-home buyers to purchase with just 5% deposit without paying LMI. The government guarantees the gap between your deposit and the 20% threshold, removing the lender’s risk. With no place caps in 2026, this is more accessible than ever — and one of the most valuable tools available to first-home buyers.

Guarantor Loan

A parent or close family member with equity in their property can act as guarantor, providing security that eliminates the LMI requirement. This is popular for buyers with strong incomes but modest deposits. Make sure you understand all the steps involved in buying before proceeding — a guarantor arrangement comes with real risk for the person providing security.

Professional LMI Waivers

Some lenders waive LMI for specific professions — doctors, dentists, lawyers, accountants, and others — at LVRs up to 90% or even 95%. Eligibility varies significantly by lender. If you’re in one of these fields, ask your broker specifically about LMI waivers.

Is Paying LMI Ever Worth It?

Sometimes. If property prices in your target area are rising faster than you can save, the cost of delaying to accumulate a 20% deposit may outweigh the LMI premium. Buying sooner with LMI and capturing capital growth can make financial sense. This is a calculation worth running with your broker for your specific market and timeline.

Frequently Asked Questions

Does LMI protect me if I can’t make repayments?

No. LMI protects the lender. If you default and the property sells for less than the outstanding balance, LMI covers the lender’s shortfall — and the insurer may then pursue you to recover what they paid. It provides you no personal cover.

Can I avoid LMI with a 15% deposit?

Not typically. LMI applies any time LVR exceeds 80%, so a 15% deposit (85% LVR) still incurs LMI. Your options are topping up to 20%, using the First Home Guarantee, or using a guarantor.

Is LMI tax-deductible on investment properties?

Yes, but it must be spread over five years or the loan term (whichever is shorter) — it’s not immediately deductible in full. Always confirm your specific position with your accountant.

Can I transfer LMI when refinancing?

No. LMI is non-transferable. If you refinance and your LVR is still above 80%, you may pay LMI again with the new lender. This is one reason why refinancing when equity is low can be costly.
