What Exactly Is LMI?
Lenders Mortgage Insurance (LMI) is an insurance policy that protects the lender (not you) in the event that you default on your home loan and the property is sold for less than the outstanding loan balance. It is typically required when your loan-to-value ratio (LVR) exceeds 80%, which means you are borrowing more than 80% of the property value.
To put it plainly: if you buy a $600,000 property with a $48,000 deposit (8%), your LVR is 92% and you will need to pay LMI. This insurance is paid by you but exists solely to protect the lender. If you default and the bank cannot recover the full loan balance from the sale of the property, the LMI insurer compensates the lender. You, the borrower, are still liable for any remaining debt.
LMI is calculated as a percentage of the loan amount and varies based on your LVR and the total loan size. The premium is typically capitalised (added to) your home loan rather than paid upfront, meaning you also pay interest on the LMI premium for the life of the loan, increasing the total cost.
LMI does NOT protect you. It protects the lender. If you default and your property is sold for less than the loan balance, the LMI insurer pays the lender, then the insurer can pursue you for the shortfall. LMI is entirely for the lender benefit.
How Much Does LMI Cost in Australia?
LMI costs vary depending on your lender, insurer, loan amount and LVR. The two major LMI providers in Australia are QBE and Helia (formerly Genworth). The table below gives rough indicative costs for a $600,000 loan (figures are indicative and vary by lender).
| LVR | Approximate LMI Premium (on loan) | What It Means |
|---|---|---|
| 85% (10% deposit + costs) | Approximately $8,000 to $12,000 | 15% equity, modest LMI |
| 90% (10% deposit, no costs covered) | Approximately $12,000 to $18,000 | 10% equity, significant LMI |
| 95% (5% deposit) | Approximately $20,000 to $28,000 | 5% equity, maximum LMI bracket |
The LMI premium is typically added to your loan balance. On a 30-year loan at 6%, a $15,000 LMI premium added to your loan costs approximately $27,000 in additional interest over the life of the loan, making the true cost of a 95% LVR significantly higher than the premium alone suggests.
You can get a specific LMI estimate through your broker or directly from the QBE LMI estimator. Note that different lenders use different LMI insurers, and the premium may vary between lenders even for the same LVR.
Who Pays LMI and When?
The borrower pays LMI, despite it being for the lender benefit. The premium is calculated at loan settlement and is typically capitalised (added to) your loan amount rather than paid as an upfront cash expense. This is why many borrowers do not feel the impact immediately, though they pay interest on the added amount for the life of the loan.
LMI is a one-off premium, not an ongoing annual payment. If you refinance your loan while your LVR is still above 80%, you will generally need to pay LMI again with the new lender (though some lenders may waive or reduce the premium in certain circumstances, and a small credit may apply if you switch within the same insurer network).
Once your LVR falls below 80%, through a combination of repayments, property value increases and additional contributions, you are no longer required to pay LMI on future loans or refinances. You do not receive a refund on previously paid LMI premiums in most cases, though some insurers offer partial refunds in the early years if you repay the loan quickly.
5 Ways to Avoid Paying LMI
1. Save a 20% Deposit
The most straightforward way to avoid LMI is to save a deposit of at least 20% plus enough to cover buying costs (stamp duty, conveyancing, etc.). This is the traditional approach, though in expensive markets like Sydney and Melbourne it can take many years to accumulate a 20% deposit on a median-priced property.
2. Use a Guarantor Loan
A family guarantor (typically a parent) can use the equity in their property as additional security, allowing you to borrow up to 100% of the purchase price without paying LMI. The guarantor does not make repayments, but their property is at risk if you default. Once your own equity reaches 20%, the guarantee can be removed. Independent legal advice for the guarantor is strongly recommended before proceeding.
3. First Home Guarantee Scheme
The federal government First Home Guarantee allows eligible first home buyers to purchase with just a 5% deposit and no LMI. The government guarantees the remaining 15% to the lender. From October 2025, places are uncapped and income caps have been removed. Property price caps that vary by location still apply. Check current eligibility and caps at Housing Australia.
4. Seek Lenders With Lower LMI Thresholds
Some lenders offer LMI-free lending up to 85% LVR, or have negotiated discounted LMI rates for certain borrower profiles. A mortgage broker can identify which lenders on their panel offer the best LMI terms for your specific situation and loan size. This is one area where using a broker rather than going direct to a single lender can result in significant savings.
5. Professions Waiver
Certain professions receive LMI waivers from many lenders, allowing these borrowers to purchase at up to 90% LVR without paying LMI. Qualifying professions typically include medical practitioners, dentists, lawyers, accountants and other high-income professionals. Requirements vary by lender, usually including minimum income levels and specific professional credentials. Ask your broker whether your profession qualifies.
Is LMI Ever Worth Paying?
Despite its reputation, LMI is not always the worst option. In some circumstances, paying LMI and entering the market sooner is financially preferable to waiting years to save a larger deposit, particularly in markets where property prices are growing faster than your savings rate.
For example: if you have a $45,000 deposit (7.5% on a $600,000 property) and would need three more years to save the additional $75,000 to reach 20%, but property prices in your target suburb are growing at 5% to 8% per year, waiting could mean the property costs $695,000 to $756,000 by the time you have enough saved. You may end up worse off despite avoiding LMI.
The decision depends on: local market conditions and expected price growth, how long it will take to save the additional deposit, the actual LMI premium cost for your loan, and whether you qualify for any LMI avoidance schemes. A broker can model both scenarios with real numbers.
If you decide to pay LMI, consider it the cost of entry into the property market rather than a waste of money. It is a one-off cost that may be outweighed by years of capital growth, building equity through repayments, and the stability of owning your own home.
Comparing LMI Cost vs Continuing to Rent
The alternative to paying LMI is often continuing to rent while saving a larger deposit. Rent represents money that leaves your household permanently. Every dollar of rent builds no equity, generates no capital gain and provides no long-term financial security. If you pay $2,500 per month in rent while saving an additional $75,000 over three years, your total rent expense is $90,000. Compared to a $15,000 LMI premium paid now, the maths often favours entering the market earlier.
That said, renting allows flexibility, avoids the risk of buying at the top of a market cycle, and preserves optionality if your personal circumstances are likely to change. The rent versus buy decision is personal and depends on far more than just LMI costs alone.
