What is lenders mortgage insurance (LMI)?

Sergio Stefano

By Sergio Stefano, CEO & Head Broker

Lenders Mortgage Insurance is one of the most misunderstood costs in Australian home buying, starting with its name. Here is the plain-English version: LMI is insurance that you pay for but that protects the lender, not you.

Who LMI actually protects

If a borrower defaults and the property sells for less than the loan owing, LMI covers the lender’s shortfall. The borrower who paid the premium gets no protection from it at all, and can even remain liable to the insurer for the shortfall it paid out. It is, bluntly, a fee for being allowed to borrow with a smaller deposit.

When it applies

The common trigger is borrowing more than 80% of the property’s value, what lenders call a loan-to-value ratio, or LVR, above 80%. Buy a $600,000 home with $60,000 down and you are borrowing at 90% LVR: LMI territory at most lenders. The premium scales with both the loan size and how far above 80% you go, which is why the last few percent of deposit can be worth a surprising amount.

What it can cost

Premiums range from a few thousand dollars to tens of thousands on larger loans at high LVRs. Most borrowers capitalise the premium, add it to the loan, which softens the upfront sting but means paying interest on it for up to 30 years. Neither choice is wrong; they are trade-offs to make with open eyes.

The legitimate ways to reduce or avoid it

Is paying LMI ever the right call?

Sometimes, yes. Waiting 2 more years to save the full 20% has its own cost if the market moves while you save. For some buyers, paying LMI to buy years earlier is a rational, deliberate trade. The mistake is not paying LMI; it is paying it accidentally, without knowing the alternatives existed.

The best LMI decision is an informed one, and informed is free: our advice costs you nothing.

LMI questions

Does LMI protect me?

No, and this is the most misunderstood part. LMI protects the lender if you default and the sale of the property does not cover the debt. You pay the premium; the lender gets the protection. You may still owe the insurer any shortfall.

When does LMI apply?

Typically when you borrow more than 80% of a property's value, though the threshold varies by lender and borrower profile. The higher above 80% you go, the more the premium climbs.

Can LMI be added to the loan?

Usually yes, which spreads the cost but means paying interest on it for the life of the loan. Whether that trade-off makes sense depends on your situation and how long you keep the loan.

Is paying LMI always bad?

No. For some buyers, paying LMI to enter the market years earlier is a rational trade, especially in a rising market. It is a cost to be weighed, not a monster to be feared. The point is choosing it deliberately.

How do profession waivers work?

Some lenders waive LMI at higher borrowing ratios for eligible professions such as medical practitioners and, at some lenders, other professionals. Policies differ and change; our medico and professional lending page covers the concept.
