How can I avoid Lenders Mortgage Insurance?

The main ways to avoid Lenders Mortgage Insurance are: save a 20 per cent deposit so your loan to value ratio is 80 per cent or less, use an eligible government guarantee that replaces the need for insurance, use a family guarantor who secures part of the loan, or qualify for a profession based waiver that some lenders offer to certain occupations.

Lenders Mortgage Insurance is one of the larger costs a buyer with a smaller deposit can face, and it protects the lender, not you. It is worth understanding what it is and the legitimate ways to avoid it, because the right approach can save a meaningful amount.

What Lenders Mortgage Insurance is

Lenders Mortgage Insurance is a one off premium a lender charges when you borrow with a deposit below 20 per cent, meaning a loan to value ratio above 80 per cent. It insures the lender against loss if you cannot repay. It does not protect you, and it is usually added to the loan, so you pay interest on it over time.

Save a 20 per cent deposit

The most direct way to avoid it is to reach a 20 per cent deposit, which puts your loan to value ratio at 80 per cent or below. At that level most lenders do not charge insurance. The downside is the time it takes to save, and the risk of prices moving while you save, so it is a trade off rather than an automatic win.

Use a government guarantee

Eligible first home buyers may use a government guarantee, under which the government guarantees part of the loan so the lender treats it as lower risk and does not require insurance. This can let you buy with a deposit as low as 5 per cent without paying a premium. Eligibility rules and property price caps apply, and you apply through a participating lender or broker.

Use a family guarantor

A family guarantor, often a parent, can secure a portion of your loan against their own property. This effectively lifts your security to the equivalent of a larger deposit, so the lender may not require insurance. The guarantor takes on a real obligation for the guaranteed portion, so they should get independent legal advice, and the guarantee can often be released later once you have built enough equity.

Profession based waivers

Some lenders waive Lenders Mortgage Insurance for borrowers in certain occupations they consider lower risk, such as some medical, legal, accounting and other professional roles. The eligible occupations, the maximum loan to value ratio and the conditions vary by lender, so this is worth checking if your profession may qualify.

Weigh the cost of waiting against the premium

Avoiding insurance is not always the best financial outcome. Paying a premium to buy sooner can sometimes beat waiting years to save a larger deposit while prices and rent rise. The premium is a real cost, but so is staying out of the market. The right call depends on your circumstances and the market.

Insurance does not transfer

It is worth knowing that Lenders Mortgage Insurance generally does not transfer between lenders or loans. If you refinance, you may face a fresh premium with the new lender if your loan to value ratio is still above 80 per cent. That is one reason building equity past the 80 per cent mark before refinancing can matter.

Find the cheapest path for you

Because the options differ in cost and eligibility, the useful step is to compare them for your situation. A broker can tell you whether a guarantee, a guarantor or a waiver applies to you, and whether avoiding the premium or paying it and buying sooner is the better move, usually at no cost to you.

In our experiencePeople often assume avoiding the premium is always right, but sometimes paying it and getting in sooner beats saving for years while prices climb. The smart move is to compare the real cost of each path, not to treat the premium as something to dodge at any price.

Frequently asked questions

What is Lenders Mortgage Insurance?▾

A one off premium a lender charges when you borrow with a deposit below 20 per cent, insuring the lender, not you, against loss if you default. It is usually added to the loan, so you pay interest on it over time.

What deposit avoids Lenders Mortgage Insurance?▾

Generally a 20 per cent deposit, giving a loan to value ratio of 80 per cent or below. At that level most lenders do not charge the premium.

Can a guarantor help me avoid the insurance?▾

Yes. A family guarantor can secure part of your loan against their own property, lifting your effective security so the lender may not require insurance. The guarantor takes on a real obligation and should get independent legal advice.

Does Lenders Mortgage Insurance transfer if I refinance?▾

Generally no. It usually does not transfer between lenders, so refinancing while still above an 80 per cent loan to value ratio can trigger a fresh premium with the new lender.
