Lender’s Mortgage Insurance (LMI) is an insurance policy, which protects your bank if you default on the loan (i.e. stop paying your loan). While the bank takes out the policy, you pay the premium. Generally you can ‘capitalise’ the premium – meaning that instead of paying it upfront in one hit, you roll it into the total amount you owe, and it becomes part of your regular mortgage repayments.

This additional cost is typically required when you have less than 20 per cent savings, or a loan with an LVR of 80 per cent or higher, and it can run into thousands of dollars. The policy is not transferrable, so if you sell and buy a new house with less than 20 per cent equity, then you’ll be required to foot the bill again, even if you borrow with the same lender.

Some lenders, such as the Commonwealth Bank, charge customers with a small deposit a Low Deposit Premium or LDP instead of LMI. The cost of the premium is included in your loan so you pay it off over time.
