Lenders mortgage insurance (LMI) is required when the value of a loan is more than 80% of a property’s purchase price, or property valuation if refinancing. In very basic terms, a lender considers a loan to carry a higher risk if the Loan to Value Ratio (LVR) is above 80%, in which case LMI is payable.

Not to be confused with mortgage protection insurance, which is designed to protect the borrower, LMI covers the lender’s risk within a residential mortgage transaction in case the borrower fails to make loan repayments. LMI is a fairly common practice within the industry, particularly for first home buyers who may struggle to save a 20% deposit.

Even though the actual property acts as security for the mortgage, the nature of the property market, like any investment class, means there is a chance that its value declines. This could result in a financial loss for the lender if the borrower is unable to repay the loan and the property is sold at a price below the value of the loan.

The cost of the LMI premium is dependent on several factors, such as the loan size and property value. Most insurers are flexible when it comes to the method of payment of LMI, it can either be a one-off upfront premium payment, or a premium could be included in the overall cost of the loan and included in the regular repayments.

It is not transferable, which means a new loan, for example if the borrower refinances the loan, may require a new LMI premium depending on how much equity the borrower has in the property.

Depending on your circumstances, you could save for a higher deposit – a higher deposit means a smaller loan amount and therefore a lower LVR thereby reducing the lender’s risk.

If you don’t have the financial capacity to meet a 20% deposit but still want to avoid LMI, you do have the option of getting a guarantor for your loan. A close relative, such as a parent, sibling or perhaps a grandparent, may be eligible to act as a guarantor, and they use the equity in their property to help you secure yours and keep your total loan below 80%. However, it’s important to remember that acting as a guarantor does come with some risks too.
