How to avoid or reduce lenders mortgage insurance

Lenders mortgage insurance catches a lot of first home buyers off guard, mostly because it protects the lender, not you, yet you are the one who pays for it. Understanding when it applies and how to reduce or avoid it can meaningfully change the total cost of your loan.

What triggers lenders mortgage insurance

LMI generally applies when you borrow more than around 80% of the property’s value, meaning your deposit is smaller than roughly 20%. The lender takes on more risk at a higher loan-to-value ratio, and the insurance premium covers that risk, not any loss to you personally.

The premium itself is usually calculated as a percentage of the loan amount, scaling up as your deposit shrinks relative to the purchase price. It can be paid upfront at settlement or capitalised into the loan, meaning it is added to what you borrow and repaid with interest over time.

Ways to avoid or reduce it

Reach the 20% deposit threshold. The most direct way to avoid LMI is saving a deposit at or above roughly 20% of the purchase price, though this takes longer and is not realistic for everyone given how quickly property prices can move.

Use a guarantor loan. A family member can offer equity in their own property as additional security, which can let you borrow above 80% without triggering LMI, since the lender’s risk is offset by the guarantee rather than the insurance.

Check eligibility for a low-deposit government scheme. Some government guarantee schemes let eligible first home buyers purchase with a smaller deposit, sometimes as low as 5%, without LMI, because the government guarantee covers the shortfall in security. These schemes usually have income and property price caps and limited places.

Ask about professional waivers. A small number of lenders waive LMI for certain occupations, such as some medical or legal professionals, as part of specific lending policies. This is lender-specific and not universally available.

Weighing LMI against waiting

Option	Deposit needed	Trade-off
Standard 20% deposit	~20% of purchase price	Longer to save, but no LMI cost
Pay LMI	As low as 5 to 10%	Buy sooner, added premium cost
Guarantor loan	Can be below 20%	Avoids LMI, but ties in a family member’s equity
Government guarantee scheme	Often ~5%	Avoids LMI, subject to caps and availability

Is it ever worth paying?

Paying LMI is not automatically a bad outcome. If property prices in your target area are rising faster than you can realistically save a larger deposit, paying the premium to buy sooner can end up cheaper overall than waiting years for a bigger deposit while prices climb. This is a genuinely personal calculation that depends on your income, savings rate, and the local market, so it is worth running the numbers with a broker rather than assuming either path is automatically right.

What the premium actually depends on

LMI premiums are not a flat fee. Insurers price them based on your loan-to-value ratio, the loan amount, and sometimes the type of property and how you intend to use it, such as owner-occupier versus investment. A borrower at 95% LVR pays noticeably more than one at 85%, since the gap to that 80% threshold is larger. This is one reason even a modest increase in your deposit, say from 10% to 15%, can meaningfully reduce the premium even if it does not eliminate it outright. Some lenders also price LMI slightly differently from one another for the same LVR band, which is another area where comparing across a broker’s panel can turn up a cheaper path to the same outcome.

A common misconception worth clearing up

LMI is sometimes confused with mortgage protection insurance, which covers your repayments if you lose income. They are entirely different products. LMI protects the lender if you default, not you, and it does not pay out any benefit to the borrower under any circumstance. Understanding this distinction matters because it explains why the premium can feel like an odd cost: you are paying for a safeguard that exists purely to make the lender comfortable extending a higher-risk loan, not to protect your own position.

This is general information about how lenders mortgage insurance typically works and is not personal financial advice. Premiums, thresholds and available waivers vary by lender and change over time, so confirm current details before deciding.
