How it works

  • Lenders Mortgage Insurance (LMI) is a one-off, non-refundable, non-transferrable premium that's added to your home loan. It's calculated based on the size of your deposit and how much you borrow. The more you contribute to the purchase price of your property, the lower the cost will be. LMI protects the bank against any loss we may incur if you are unable to repay your loan.

    The circumstances of your home loan will determine whether LMI or a Low Deposit Premium (LDP) may apply. This includes when you restructure your home loan, top it up or refinance. This is because there may be an increased risk associated with each application.

    We require you to take out LMI where there is an increased risk associated with your loan. 


    • If you want to buy a house that’s worth $500,000, we would typically require you to have a deposit of $100,000 (20% of the property’s value). If you’ve only saved $50,000, but you have sufficient income to support the loan, you may be able to take advantage of Lenders Mortgage Insurance. We would then lend you the $450,000 needed to buy your new home. 

    Our Home Lending Specialists can help explain when Lenders Mortgage Insurance may apply to your home loan, how much it will cost and what happens if there is a shortfall debt.

Things you should know

    • LMI is designed to protect us (CommBank), not you (the borrower), against the risk associated with providing you with a low deposit home loan and the potential loss we may incur if you’re unable to repay your home loan
    • All premiums are capitalised (added) to the total home loan amount when your home loan is settled. This means you’ll pay more interest over the agreed contracted loan term   
    • If you're unable to repay your home loan, we may step in to assist with the sale of the property. If the proceeds from the sale are not enough to pay off the loan in full, our insurer, Helia, may seek to recover the remaining debt from any borrower(s) (you) and, where applicable, any guarantor(s) on the home loan
    • If we ask you to pay LMI we won’t ask you to pay a Low Deposit Premium
    • You can get indicative quotes for LMI using our stamp duty (upfront costs) calculator
