LMI — you pay it, but it protects someone else.
If your deposit is under 20%, your lender will probably make you pay an insurance premium that runs into the tens of thousands of dollars. The strange part: the insurance protects them, not you. Here's why it exists, when it's worth paying, and how to avoid it if you can.
What LMI actually is
Lenders Mortgage Insurance is a one-off insurance premium that covers the lender against you defaulting on your loan. If you stop making payments and the bank sells the property for less than it lent you, the insurer pays the lender the shortfall. The bank stays whole. You still owe the insurer.
Here's the part most people miss: you pay the premium, but you're not the one being insured. The bank is. You're paying for insurance that protects them. If you ever do default, the insurer can then pursue you for the loss.
The reason it exists is that lenders treat loans with deposits under 20% as higher-risk. They're willing to lend, but only if the extra risk is covered. The premium passes that cost back to you, the borrower.
Why borrowers accept this
If LMI sounds unfair, that's because the framing is. The economic logic is straightforward though: without LMI, banks would simply refuse to lend to borrowers with small deposits. The product exists to make those loans possible.
For most first home buyers in Australia, the choice isn't "pay LMI or get the same loan cheaper" — it's "pay LMI or wait several years to save more deposit". And waiting has its own cost: rent paid in the meantime, plus a moving target if house prices rise.
The widget below makes that trade-off concrete. Pick your scenario and see whether paying LMI to buy now actually wins.
How is the premium calculated?
LMI premium is roughly a percentage of your loan amount, with the rate driven by two things: your LVR (how high a deposit you have) and your loan size (bigger loans get charged a higher percentage). Premium rates are not publicly standardised — each lender negotiates them with insurers like Helia and QBE — but the broad shape is consistent.
A few patterns to know:
- Just over 80% LVR is much cheaper than 90%+. A push to get to 80% (even with a small gift or extra savings) can save you thousands.
- The premium can be paid upfront at settlement OR capitalised — added to your loan balance and paid off over the loan term. Capitalising means you also pay interest on the LMI itself.
- LMI is a one-off cost, not annual. Once paid, it's done — even if your equity later changes.
When is paying LMI actually worth it?
The real ways to avoid LMI
If LMI is genuinely the wrong move for your scenario, there are several legitimate paths around it. Each works for some people, not others.
1. Get to 20% somehow
The simplest path. Save more, wait longer, or close the gap with a gift or contribution from family. A gifted deposit (usually requires a statutory declaration that it's not a loan) counts toward your deposit calculation.
2. First Home Guarantee (formerly First Home Loan Deposit Scheme)
An Australian Government scheme that lets eligible first home buyers purchase with just a 5% deposit — no LMI. The government guarantees the gap (effectively acting as your insurer). Places are limited each year; income and property price caps apply, and they vary by location. Worth checking the current details on the government's housingaustralia.gov.au site before assuming you qualify.
3. Profession-based waivers
Several lenders waive LMI for borrowers in certain professions — typically medical (doctors, dentists, vets), accounting, and legal. These borrowers are considered low-risk because of high, stable income. The list of qualifying professions varies by lender. If you're in one of these fields, ask your broker specifically about a "professional package" or "no-LMI loan."
4. Guarantor loans
A family member (typically parents) uses their own property as additional security on your loan. The bank's risk is reduced because they can fall back on the guarantor's equity, so they don't require LMI. This is a real obligation on the guarantor — if you default, they're on the hook. Common, but worth getting legal advice before going this route.
5. Look at slightly cheaper property
Sometimes the cleanest fix. If you're at 85% LVR on a $700k purchase, your deposit covers 20% of a $525k property. Trading down by 25% (or up the deposit ladder) avoids LMI entirely. Not always desirable, but always an option.
The honest summary
LMI is not a scam, but it's not free money for the bank either — it's a real risk-pricing product that makes lending to higher-LVR borrowers economically possible. The framing that frustrates people ("I'm paying insurance that protects someone else") is accurate, but the alternative (banks simply not lending below 20% deposit) would be worse for most first home buyers.
For most Australians in a growing housing market, paying LMI to buy earlier mathematically beats waiting to save a 20% deposit. That's not because LMI is cheap — it's because price growth typically outpaces savings growth. The widget above lets you check whether that holds in your specific scenario, because it doesn't hold for everyone.
If you do pay LMI, do it eyes-open: it's a one-off cost of getting in, not a recurring tax on your loan. Don't pretend it's painless — but don't pretend it always loses, either.
