The True Cost of Lenders Mortgage Insurance (and How to Avoid It)

Lenders Mortgage Insurance (LMI) is one of the largest hidden costs in property purchasing. Here's what it actually costs, when it applies, and five legitimate ways to avoid paying it.
What Is LMI?
LMI protects the lender (not you) if you default on your loan. It's required when you borrow more than 80% of the property value — in other words, when your deposit is less than 20%.
What Does It Cost?
LMI is calculated based on your loan amount and Loan-to-Value Ratio (LVR). On an $800,000 property with a 10% deposit ($80,000), LMI typically costs between $15,000 and $25,000. On a $1.2M property with 5% deposit, it can exceed $40,000.
5 Ways to Avoid LMI
1. Save a 20% Deposit
The most straightforward approach. On an $800,000 property, that's $160,000.
2. Use the First Home Guarantee
If you're eligible, the government guarantees the gap between your deposit and 20%, eliminating the need for LMI.
3. Family Guarantee (Security Guarantee)
A parent or family member can offer their property as additional security, covering the LMI gap without gifting cash.
4. Use a Lender That Doesn't Charge LMI
A small number of lenders waive LMI for certain professions (doctors, lawyers, accountants, engineers) or for borrowers with strong income profiles.
5. Capitalise LMI Into the Loan
While this doesn't avoid LMI, it removes the upfront cash requirement. You'll pay interest on the capitalised amount, but it preserves your savings for other costs.
Is LMI Always Bad?
Not necessarily. If property prices are rising faster than you can save, paying LMI to enter the market sooner may cost less than the capital growth you'd miss by waiting another 2-3 years to save 20%.
We model both scenarios — paying LMI now vs. waiting to save more — so you can make an informed decision with real numbers.
