Most first home buyers have heard of Lenders Mortgage Insurance. Fewer still understand what it actually does — or that despite paying for it, it offers them zero protection. Here's everything you need to know about LMI in 2026, including the exact costs and how to avoid paying it altogether.
What Is Lenders Mortgage Insurance?
Lenders Mortgage Insurance is a one-off insurance premium that protects your lender — not you — if you default on your home loan and the property sells for less than what you owe.
That's the most important thing to understand about LMI: the borrower pays for it, but the bank is the one who benefits.
If you default and your property is sold at a loss, the LMI insurer (either Helia, formerly Genworth, or QBE) compensates your lender for the shortfall. You, however, are still fully liable. The insurer can — and often does — pursue the borrower to recover what it paid out.
LMI is not income protection. It is not mortgage protection insurance. And it is not optional once you trigger the threshold.
When Does LMI Apply?
LMI is triggered when your loan-to-value ratio (LVR) exceeds 80%. In plain terms: if your deposit is less than 20% of the purchase price, you will almost certainly need to pay LMI.
LVR is calculated as: Loan Amount ÷ Property Value × 100
So on a $750,000 property:
- 20% deposit ($150,000) → LVR 80% → No LMI
- 10% deposit ($75,000) → LVR 90% → LMI applies
- 5% deposit ($37,500) → LVR 95% → LMI applies (higher premium)
Some lenders also require LMI on investment properties at lower LVRs than for owner-occupiers. A handful of lenders waive LMI for certain professions (doctors, lawyers, accountants) at up to 90% LVR — but these are exceptions, not the rule.
How Much Does LMI Cost?
LMI is not a flat fee. It's calculated as a percentage of your loan amount, and that percentage rises sharply as your LVR increases. The smaller your deposit, the more expensive LMI becomes — both in dollar terms and as a percentage.
Here's what borrowers typically pay in 2026:
LMI Cost Estimates by Deposit Size
| Property Value | Deposit | LVR | Loan Amount | Est. LMI |
|---|---|---|---|---|
| $600,000 | $90,000 (15%) | 85% | $510,000 | ~$5,600 |
| $600,000 | $60,000 (10%) | 90% | $540,000 | ~$10,400 |
| $600,000 | $30,000 (5%) | 95% | $570,000 | ~$25,300 |
| $750,000 | $75,000 (10%) | 90% | $675,000 | ~$13,000 |
| $750,000 | $37,500 (5%) | 95% | $712,500 | ~$31,600 |
| $900,000 | $90,000 (10%) | 90% | $810,000 | ~$15,600 |
| $900,000 | $45,000 (5%) | 95% | $855,000 | ~$37,900 |
Note: LMI applies at any LVR above 80% — including the 85% row above. Figures are estimates based on industry premium rates from Helia/QBE and may vary by lender, loan type, and insurer used. Always obtain a quote specific to your situation.
The jump from 10% to 5% deposit is dramatic. On a $750,000 property, dropping from a 10% deposit to a 5% deposit more than doubles your LMI cost — from roughly $13,000 to over $31,600.
Can LMI Be Added to Your Loan?
Yes. Most lenders allow you to capitalise LMI — meaning the premium is added to your loan balance rather than paid upfront. This is common because buyers are already stretched covering their deposit, stamp duty, and purchase costs.
But capitalising LMI carries a real long-term cost. You pay interest on the LMI amount for the life of the loan.
The True Cost of Capitalising LMI
- $13,000 LMI capitalised into a 6.0% loan over 30 years
- Total cost including interest: approximately $27,800
- That's more than double the original premium
Capitalising LMI solves a cash flow problem at settlement but increases your total cost significantly. It also increases your LVR slightly, which is worth checking before you proceed.
How to Avoid Paying LMI
There are four main ways to avoid LMI. Each has trade-offs.
1. Save a 20% Deposit
The traditional approach. Get your deposit to 20% of the purchase price and you clear the LMI threshold entirely. The downside is time — in Sydney, where the median house price is around $1.5 million, saving 20% ($300,000) can take a decade or more for many households. See our guide on how much deposit you need to buy in Sydney.
2. First Home Guarantee Scheme
The most practical option for many first home buyers right now. The federal government guarantees the difference between your deposit and 20%, so you can buy with just 5% down and no LMI. See our full guide to the First Home Guarantee and 5% deposit scheme.
As of October 2025, the scheme was significantly expanded:
- No place cap — all eligible first home buyers can access it (previously limited to 35,000 places per year)
- No income limit — removed entirely
- Property price cap raised — Sydney metro now $1,500,000 (up from $900,000)
You still own 100% of your property. The government provides no money — it simply guarantees the loan, which allows your lender to waive LMI. On a $700,000 purchase, this can save you $15,000–$25,000 in LMI costs.
3. Help to Buy Scheme
Launched December 2025, Help to Buy takes a different approach. The government co-purchases your home alongside you — contributing up to 30% for existing homes or 40% for new builds. You need as little as a 2% deposit and pay no LMI.
The trade-off: you don't own 100% of your home. The government's share is repaid when you sell, or you can buy it out over time. Income caps apply: $100,000 for individuals, $160,000 for couples.
4. Guarantor Home Loan
A parent or close family member pledges equity in their own property as additional security. This reduces your effective LVR below 80%, eliminating the need for LMI — without the guarantor providing any cash.
On a $700,000 purchase with a 5% deposit ($35,000), a guarantor covering the remaining 15% ($105,000) with their home equity means your loan effectively carries an LVR of 80% in the lender's eyes. The result: no LMI, and you entered the market with a much smaller deposit.
The risk sits with the guarantor — their property is on the line for the guaranteed portion. This needs careful family discussion before proceeding. Most lenders also require the guarantor to obtain independent legal advice.
Is Paying LMI Ever Worth It?
Sometimes, yes — particularly in a rising market.
If property prices increase while you spend 3–5 years saving a larger deposit, the gain in equity from entering the market earlier can far outweigh the LMI cost. In Sydney, where prices have grown significantly over the long term, a buyer who paid $15,000 LMI and entered the market in 2021 has typically come out ahead compared to one who waited to save a 20% deposit.
LMI also allows you to buy in a suburb you can afford now, rather than a cheaper suburb later because prices moved on.
That said, LMI does not make a bad loan good. If you are at the absolute limit of your borrowing capacity, adding $15,000–$30,000 to your loan and starting with minimal equity is a genuine risk — especially after two rate rises in 2026. Borrowers considering LMI should stress-test their repayments at a cash rate of 4.35% or higher before proceeding.
LMI vs Stamp Duty — Which Hits Harder?
For most Sydney buyers, stamp duty is the larger cost — but both need to be factored in before purchase.
LMI vs Stamp Duty: Sydney Comparison
| Property Value | Stamp Duty (NSW) | LMI at 90% LVR | LMI at 95% LVR |
|---|---|---|---|
| $600,000 | ~$22,000 | ~$10,400 | ~$25,300 |
| $750,000 | ~$29,000 | ~$13,000 | ~$31,600 |
| $900,000 | ~$36,000 | ~$15,600 | ~$37,900 |
NSW stamp duty estimates for owner-occupiers at the standard rate. First home buyers may be eligible for full exemption (properties up to $800,000) or a concession (up to $1,000,000) — verify current thresholds with your broker as these can change. LMI figures are estimates only.
Crucially, LMI can be avoided with the right strategy. Stamp duty generally cannot — unless you qualify for a first home buyer exemption.
Which Lender's LMI Is Cheapest?
LMI costs vary between lenders because they use different insurers — Helia (formerly Genworth) or QBE — and negotiate their own premium rates.
- Commonwealth Bank — uses Helia exclusively
- Westpac — self-insures loans between 80–90% LVR; uses an external insurer above 90%
- Most other major and non-major lenders — use either Helia or QBE
Because premiums differ, two identical loan applications at different lenders can attract different LMI costs. A mortgage broker can compare LMI costs across lenders as part of finding the right loan — not just the interest rate.
One more thing worth knowing: some lenders refund a portion of LMI if you pay off your loan early. Westpac has historically refunded 40% if repaid within Year 1, 20% within Year 2 — though refund policies change frequently, so confirm the current policy with your broker before you commit. CBA has not offered LMI refunds.
