What is Lenders Mortgage Insurance (LMI)?

Lenders Mortgage Insurance is a type of insurance that protects lenders from financial loss in case a borrower is unable to meet their home loan repayments. In Australia, LMI is typically required when a borrower has a deposit of less than 20% of the property’s purchase price. This insurance allows lenders to offer loans to a broader range of borrowers who might not otherwise qualify for a home loan due to a smaller deposit.

How Does LMI Work?

LMI is a one-off, non-refundable premium that is usually paid at the time of loan settlement. The cost of LMI can vary significantly depending on the lender, loan amount, and the size of the deposit. Although it protects the lender, not the borrower, it can help borrowers access the property market sooner by reducing the necessary deposit.

How is LMI Calculated?

The calculation of LMI premiums is based on the loan-to-value ratio (LVR) and the amount borrowed. An LVR above 80% generally triggers the need for LMI. For example, if you're purchasing a $500,000 property with a $50,000 deposit, your LVR would be 90%, likely necessitating LMI.

Benefits and Drawbacks of LMI

Benefits

  • Access to the Property Market: LMI can be a gateway for buyers with small deposits to enter the property market sooner.
  • Flexibility: It allows borrowers to use their savings for other purposes, such as renovations or furnishing their new home.

Drawbacks

  • Cost: LMI can add thousands to your loan, increasing the overall cost of buying a home.
  • No Borrower Protection: LMI protects the lender, not the borrower, which means if you default, you still face financial repercussions.

Practical Tips for Managing LMI

1. Save a Larger Deposit: Aim for a 20% deposit to avoid LMI altogether. 2. Utilise Guarantors: Some lenders may waive LMI if a family member guarantees part of your loan. 3. Consider LMI Capitalisation: Some lenders allow you to add the LMI premium to your loan amount, spreading the cost over the loan term.

Common Mistakes to Avoid

  • Misunderstanding LMI Coverage: Remember that LMI doesn’t protect you, the borrower. It’s essential to have personal insurance to cover unforeseen events.
  • Ignoring LMI Costs: Failing to factor LMI into your budget can lead to financial strain. Always calculate the total loan cost, including LMI, early in your planning.
