It tends to show up right around the moment you realise how big a deposit you actually need, and it’s one of those costs that catches a lot of buyers off guard.

So let’s break it down in plain terms.

Lenders Mortgage Insurance is a one-off insurance premium that most lenders charge when you borrow more than 80% of a property’s value. In lending speak, that’s a loan-to-value ratio (LVR) above 80%.

Here’s the part that surprises people: LMI doesn’t protect you. It protects the lender. If you can’t repay your loan and the property sells for less than what’s owed, the insurance covers the lender’s loss. You’re paying for a policy that benefits someone else.

That might sound unfair, but there’s a reason it exists. A smaller deposit means more risk for the lender, and LMI is what lets them say yes to buyers who haven’t saved the full 20%. Without it, a lot of people would be waiting years longer to buy.

In most cases, the borrower pays it. If your deposit is less than 20% of the purchase price, expect LMI to be part of the conversation.

The cost isn’t fixed. It depends mainly on:

• How much you’re borrowing. Bigger loans mean bigger premiums.
• Your LVR. The smaller your deposit, the higher the premium. Borrowing at 95% costs considerably more than borrowing at 85%.
• The lender and insurer. Different lenders use different insurers and pricing.

On a large loan with a small deposit, LMI can easily run into the tens of thousands of dollars. Most lenders let you add it to your loan rather than paying it upfront, which helps with cash flow but means you’ll pay interest on it over the life of the loan.

Sometimes, yes. The most common ways are:

• Saving a 20% deposit. The simplest route, though not always realistic in today’s market.
• Using a guarantor. A family member uses equity in their own property to secure part of your loan.
• Profession-based waivers. Some lenders waive LMI for certain occupations they see as lower risk.

That last one is worth knowing about, and we’ll come back to it.

1. Is LMI the same as mortgage protection insurance?
No, and it’s a common mix-up. LMI protects the lender if you default. Mortgage protection insurance is a separate, optional policy that protects you, covering repayments if you lose your income due to illness, injury or job loss.

2. Do I get my LMI back if I sell or refinance?
Usually not. LMI is generally a one-off, non-refundable cost. If you refinance to a new lender and still owe more than 80% of your property’s value, you may even have to pay it again. Worth factoring in before switching loans.

3. Can I pay LMI in instalments?
Not really in the traditional sense, but adding it to your loan amount (called capitalising) spreads the cost across your repayments. Just remember you’ll pay interest on it too.

4. Is LMI tax deductible?
For investment properties, it can be. It’s generally treated as a borrowing expense and claimed over five years or the term of the loan, whichever is shorter. For your own home, it’s not deductible. Check with your accountant for your situation.

5. Is paying LMI ever a smart move?
It can be. If property prices in your area are rising faster than you can save, paying LMI to get in sooner might cost less than waiting. It’s a personal calculation, and a good broker can help you run the numbers both ways.

If you work in certain professional or essential roles, you may not need to pay LMI at all.

WLTH offers 0 LMI home loans for eligible workers buying an established home to live in.

Professional Workers can borrow up to 95% of the property’s value with no LMI. This applies to university-qualified professionals working in medical and allied health, law, accounting and audit, engineering or IT. TAFE or certificate-qualified professionals working in IT are also eligible.

Essential Workers can borrow up to 90% with no LMI. This covers permanently employed nurses, paramedics, state and federal police officers, firefighters, and primary and secondary school teachers in public or private schools.

In both cases, the main income earner needs to work in one of the eligible roles, and borrowing above 80% is subject to approval and the property’s location.

It won’t be the right fit for everyone, but if you’re in one of these professions and the deposit gap has been holding you back, it’s worth a conversation. Speak to your broker or call 13 WLTH to find out if you’re eligible.
