LMI Explained. Avoid Paying It.

LMI confuses almost every first home buyer. It sounds like insurance that protects you — but it doesn't. Here's exactly what it is, what it costs, and how to think about it.

01
What LMI actually is
LMI is a one-off insurance premium that protects the lender — not you — if you default on your home loan and the property sale does not cover the outstanding balance. You pay the premium but the bank benefits from the protection.
02
When LMI applies
LMI applies when your deposit is less than 20% of the purchase price — meaning your Loan to Value Ratio (LVR) is above 80%. Almost all lenders require LMI in this situation, though costs vary significantly between lenders.
03
How much LMI costs
LMI is calculated as a percentage of your loan amount and varies based on your LVR and loan size. On a $600,000 loan with a 10% deposit, LMI typically costs $12,000–$18,000. It is usually added to your loan balance rather than paid upfront.
04
Three ways to avoid LMI
Save a 20% deposit. Use a guarantor — a parent who uses equity in their property to guarantee part of your loan. Or apply under the First Home Guarantee scheme which lets eligible first home buyers borrow with 5% deposit and no LMI.
05
Is LMI always worth avoiding?
Not necessarily. If saving an extra 10% deposit takes three more years and property prices rise by 5% per year in that time, the cost of waiting can far exceed the LMI premium. In rising markets, paying LMI to enter sooner is often the better financial decision.

Common mistakes to avoid

Thinking LMI protects you
LMI protects the lender. If you default and your home sells for less than your loan balance, the insurer pays the lender — then pursues you for the shortfall. You are still liable.
Automatically trying to avoid it at all costs
Waiting years to save a 20% deposit often costs more in missed property growth than the LMI premium itself. Model both scenarios before deciding.
Not checking First Home Guarantee eligibility first
Eligible first home buyers can purchase with 5% deposit and zero LMI. Many buyers pay LMI unnecessarily because they did not check their eligibility for the scheme.
Not comparing LMI costs between lenders
LMI premiums vary significantly between lenders because they use different insurers. A specialist knows which lenders offer the most competitive LMI rates for your loan size.

💡 The real LMI question

The question is not whether to avoid LMI at all costs — it is whether paying LMI to enter the market sooner makes better financial sense than waiting to save a larger deposit. In most Sydney markets over the last decade, paying LMI and buying sooner has been the better decision.

Frequently asked questions

In most cases, no. LMI is a one-off premium that is not refundable if you sell or refinance. Some insurers offer a partial refund within the first year — conditions vary. Always check before assuming.

Yes — most lenders allow you to capitalise the LMI premium into your loan balance rather than paying it upfront. This increases your loan amount and total interest paid over time but removes the need for cash at settlement.

For investment properties, LMI may be tax deductible over five years. For owner-occupied homes, it is generally not deductible. Always confirm with your accountant for your specific circumstances.

No — LMI rates vary between lenders because they use different insurance providers. A specialist compares LMI costs across lenders as part of finding you the right loan.

LMI protects the lender if you default. Mortgage protection insurance protects you — covering your repayments if you lose your job, become ill or die. They are completely different products and you can have both.
