Lenders Mortgage Insurance—often shortened to LMI—is one of the biggest question marks for first-time buyers and anyone who hasn’t saved a full 20% deposit. The question is simple: do you have to pay it, and if so, how much?
Here’s the short answer. When your deposit is less than 20% of the property’s value, most Australian lenders will require LMI. It protects the lender if you can’t meet your repayments and they need to sell the property at a loss. You pay the premium, but the cover is for the lender’s benefit, not yours.
How LMI costs are calculated
LMI isn’t a flat fee. The premium depends on your loan amount, the size of your deposit, and the lender’s risk settings. As a general guide, the smaller your deposit, the larger the premium. For example, on a $700,000 property:
- With a 5% deposit (95% LVR), the LMI may add roughly $28,000 to your loan.
- With a 10% deposit (90% LVR), the cost might be around $14,000.
- At 15% deposit (85% LVR), it could drop to about $6,500.
- Once you reach a 20% deposit (80% LVR), no LMI applies.
These figures are indicative only. The actual cost varies between lenders and states, and factors like your employment type or whether you’re a first home buyer can influence the final number. Most lenders let you add the LMI premium to your loan balance rather than paying it upfront, which reduces your immediate cash burden but increases your overall loan size.
Ways to reduce or avoid LMI
A 20% deposit isn’t the only way to avoid LMI. Here are practical paths that many Australian buyers use:
- Family guarantee – a parent or close family member uses equity in their own property as partial security for your loan, effectively reducing the lender’s risk without requiring a larger cash deposit.
- First Home Guarantee – a government scheme that allows eligible first home buyers to purchase with a deposit as low as 5% without paying LMI, subject to property price caps and income limits.
- Professional exemptions – some lenders waive LMI for certain professions, including medical practitioners, lawyers, and accountants, even with a deposit below 20%.
- Regional First Home Buyer Guarantee – a similar government scheme for buyers in regional areas, designed to help with a lower deposit and no LMI.
These alternatives can significantly reduce your upfront costs, but each comes with its own eligibility rules. Checking whether you qualify can help you structure your loan more efficiently.
What LMI isn’t
It’s important to understand that LMI is not mortgage protection insurance, which covers you if you can’t work. LMI covers the lender’s risk, not your personal circumstances. Even if you pay the premium, you won’t receive a payout if you default—the insurance simply reimburses the lender.
Making your decision
For many buyers, especially in Australia’s competitive housing market, waiting to save a 20% deposit can mean watching property prices move further out of reach. In that scenario, paying LMI might be a calculated trade-off: the premium lets you enter the market sooner. But it’s equally sensible to explore whether a family guarantee or government scheme applies to your situation.
Comparing options is key. LMI premiums vary between lenders, and a difference in interest rate or loan features can outweigh a slightly lower LMI quote. Looking at the total cost over the loan term—not just the premium figure—gives you a clearer picture.

LMI is a cost that many buyers face, but it doesn’t have to be a surprise. By understanding how it works and what alternatives are available, you can decide whether to pay it, reduce it, or avoid it altogether.
