What Is Lenders Mortgage Insurance (LMI)?
Lenders Mortgage Insurance (LMI) is a one-off insurance premium paid by the borrower to protect the lender in case the borrower defaults on the home loan. It is typically required when the loan-to-value ratio (LVR) exceeds 80%, meaning the borrower has a deposit of less than 20% of the property’s value. LMI does not protect the borrower; it safeguards the lender against potential losses.
When Is LMI Triggered?
LMI is triggered when the LVR is above 80%. For example, if you are purchasing a property valued at $500,000 and your deposit is $50,000 (10%), your LVR is 90%, and LMI will apply. The exact threshold can vary slightly between lenders, but 80% LVR is the standard trigger point across the Australian mortgage market.

How Are LMI Costs Calculated?
LMI premiums are calculated based on the loan amount and the LVR. The higher the LVR, the higher the premium. For instance, a loan with a 95% LVR will incur a significantly higher LMI premium than one with an 85% LVR. The premium is usually a percentage of the loan amount and can be paid upfront or capitalised into the loan, meaning it is added to the total loan balance and repaid over the loan term.
Strategies to Reduce LMI Costs on High-LVR Loans

Can professional discounts help reduce LMI?
Yes, certain professionals may be eligible for LMI waivers or discounts. Some lenders offer LMI exemptions for specific occupations, such as medical professionals, lawyers, and accountants, even with an LVR above 80%. These professional packages can significantly reduce or eliminate the LMI cost, making it easier to enter the property market with a smaller deposit.
How can a larger deposit reduce LMI?
Increasing your deposit to lower the LVR is the most straightforward way to reduce LMI costs. Even a small increase in deposit can move you into a lower LVR bracket, reducing the premium. For example, going from a 90% LVR to an 85% LVR can result in noticeable savings on the LMI premium.
Are there other ways to minimise LMI expenses?
Some lenders offer LMI discounts for first-home buyers or through specific loan products. Additionally, using a guarantor, typically a family member who offers their property as additional security, can help you avoid LMI altogether by effectively reducing the LVR from the lender’s perspective. It’s important to compare different lenders’ policies, as LMI premiums and waiver conditions can vary.
Frequently Asked Questions
What is the difference between LMI and mortgage protection insurance?
LMI protects the lender if you default, while mortgage protection insurance is a separate policy that covers your loan repayments in case of illness, injury, or job loss. LMI is a one-off cost, whereas mortgage protection insurance typically involves ongoing premiums.
Can LMI be refunded if I refinance?
LMI is generally non-refundable. If you refinance your loan, you may need to pay LMI again if the new loan’s LVR is above 80%. However, some lenders may offer partial refunds if you refinance within a short period, but this is not common.
Is LMI tax-deductible for investment properties?
LMI premiums on investment property loans may be tax-deductible over the life of the loan or five years, whichever is shorter. It’s advisable to consult a tax professional for specific advice.
