What Is Lenders Mortgage Insurance (LMI)?
Lenders Mortgage Insurance is a one-off insurance premium that protects the lender, not you, if you default on your home loan and the property sells for less than the outstanding balance. Despite the name, LMI does not cover the borrower. You pay the premium, and if anything goes wrong, the lender claims against the policy.
LMI is required when you borrow more than 80% of the property value, in other words, when your loan-to-value ratio (LVR) exceeds 80%. The smaller your deposit, the higher your LVR, and the higher the LMI premium.
It's a one-off premium that can range from $5,000 to $40,000+ depending on your loan amount and deposit size. Most Australian lenders let you add LMI to your loan balance (capitalise it) rather than paying it upfront at settlement, which spreads the cost over the life of the loan, but means you pay interest on the LMI amount too.

How Much Is LMI in Australia in 2026?
Lenders Mortgage Insurance protects the lender, not you, if you default on your home loan. It's required when your deposit is less than 20% of the property value (LVR above 80%). The cost varies dramatically based on your deposit size and property value.
Typical LMI Cost Ranges
Based on Westpac's LMI calculator and current 2026 industry rates (Money.com.au, Canstar):
| Property value | 5% deposit | 10% deposit | 15% deposit |
|---|---|---|---|
| $400,000 | about $16,300 | about $8,100 | about $4,600 |
| $500,000 | about $20,400 | about $10,100 | about $5,700 |
| $600,000 | about $24,500 | about $12,200 | about $6,900 |
| $750,000 | about $30,600 | about $15,200 | about $8,600 |
| $1,000,000 | about $40,900 | about $20,300 | about $11,500 |
| $1,500,000 | about $61,300 | about $30,400 | about $17,200 |
These are estimates based on a first home buyer profile, owner-occupier, 30-year loan, NSW property. Your actual LMI may vary by plus or minus 20% based on lender, insurer, employment status, and loan product. Use the calculator above for your specific scenario.
LMI typically costs 1 to 5% of the loan amount, with NAB capping their LMI at up to 6.5% of the loan. The two main LMI providers in Australia are Helia (formerly Genworth) and QBE, though some lenders self-insure (e.g. Pepper Money) or have alternative arrangements.
The Expanded First Home Guarantee: A Game Changer for FHBs
The Federal Government's expansion of the First Home Guarantee scheme has fundamentally changed the LMI landscape for first home buyers in 2026.
Under the expanded scheme, all eligible first home buyers can purchase with as little as 5% deposit and zero LMI, with no income caps and no place limits, within the state property price caps. The government guarantees the additional 15% needed to reach a notional 20% deposit.
This is a meaningful shift. Previously, FHBG had income caps ($125K single / $200K couple) and a yearly cap on places. From 1 October 2025 both were removed and the price caps were raised, but property price caps still apply (e.g. NSW $1.5M, Melbourne $950K, Brisbane/Canberra $1M).
For a first home buyer purchasing a $600,000 property with a 5% deposit, the saving is approximately $24,500 in LMI that would otherwise apply.
Eligibility check:
- You must be a first home buyer (never owned property in Australia)
- You must intend to live in the property as your primary residence
- You must hold Australian citizenship or permanent residency
- The property must be a residential dwelling (not vacant land alone)

How to Avoid LMI Without a 20% Deposit
Beyond the expanded First Home Guarantee, four other paths to skip LMI exist:
- Family guarantor. A parent or family member uses equity in their home as additional security. This can eliminate LMI entirely with as little as 0 to 5% deposit. The guarantor is partially responsible for the debt, and a caveat may apply to their property until release. Common, but consider the family relationship implications carefully.
- Professional waivers. Some lenders waive LMI for medical, legal, accounting, and certain financial professionals, typically allowing up to 90 to 95% LVR with no LMI. Eligibility is profession-specific and lender-specific.
- Family Home Guarantee (single parents). Eligible single parents can buy with as little as 2% deposit and no LMI under this distinct government scheme. Read the full Family Home Guarantee guide.
- Lower the property price. Sometimes the most overlooked option: if a slightly cheaper property pushes your existing deposit above 20% of value, LMI vanishes entirely.
Not sure which option applies to you? Ask a broker about LMI waivers. A good broker knows which lenders offer profession waivers, which accept the First Home Guarantee, and how to structure a guarantor loan.
One other cost to factor in before settlement: your lender will require proof of building insurance on the property before they release the loan. Premiums typically run $1,200 to $2,500 per year, so compare home insurance early so the certificate of currency is ready the moment your broker locks in your loan.
LMI Strategy: Pay Now, Capitalise, or Avoid?
If you can't avoid LMI, three structural choices remain:
| Approach | Pro | Con | Best for |
|---|---|---|---|
| Pay LMI upfront | Lower total interest paid over loan life | Larger cash drain at settlement | Buyers with cash buffer beyond deposit |
| Capitalise into loan | Preserves cash at settlement | Pay interest on LMI for 25 to 30 years | Most FHBs (cash usually tight) |
| Wait + save 20% | Zero LMI, smallest loan | Property prices may rise faster than savings | Stable price markets only |
The "wait and save" path lost favour during the 2020 to 2022 property boom, when buyers who waited paid significantly more in higher prices than they saved in LMI. In flatter 2026 markets, the calculus is closer. Talk to a broker before deciding.
LMI for Investment Properties
Investment property LMI typically costs 20 to 30% more than owner-occupier LMI for the same LVR. Some lenders also cap maximum LVR at 90% for investment loans (vs 95% for owner-occupier).
The upside: LMI on investment loans is tax-deductible, claimed over five years (or the loan term, whichever is shorter). On a $25,000 LMI premium, that's roughly $5,000/year in deductions; at a 37% marginal rate, about $1,850/year tax saved.
For first home buyers considering rentvesting (buying an investment property instead of primary residence), the tax-deductibility softens the LMI cost meaningfully, but you also forfeit the expanded First Home Guarantee, which is FHB primary-residence only.

LMI: Frequently Asked Questions
How much is LMI on a $500,000 property?
LMI on a $500,000 property typically ranges from $7,000 to $20,000 depending on your deposit size. With a 15% deposit ($75,000), LMI is around $3,000 to $5,000. With a 10% deposit ($50,000), it jumps to $7,000 to $10,000. With a 5% deposit ($25,000), LMI can reach about $20,000. The smaller your deposit, the higher the premium because the lender is taking on more risk.
Can I avoid paying LMI?
Yes, there are four main ways to avoid LMI in Australia. First, save a 20% deposit so your loan-to-value ratio stays under 80%. Second, use the Australian Government 5% Deposit Scheme (formerly the First Home Guarantee) to buy with just 5% deposit and zero LMI (government guarantees the rest). Third, use a family guarantor loan where a parent offers equity in their home as additional security. Fourth, check if you qualify for a profession-based LMI waiver: doctors, lawyers, accountants, nurses and some other professionals can borrow above 80% LVR without paying LMI at participating lenders.
Is LMI added to my loan?
Usually yes. Most Australian lenders let you capitalise LMI, meaning the premium is added to your loan balance rather than paid as a lump sum at settlement. This makes the upfront cost easier to manage but means you pay interest on the LMI amount for the life of the loan. You can also choose to pay LMI upfront if you have the cash, which works out cheaper long term.
Do first home buyers pay LMI in 2026?
Most do not. The Australian Government 5% Deposit Scheme (formerly the First Home Guarantee) eliminated LMI for the majority of Australian first home buyers from 1 October 2025: no income cap, unlimited places, raised property price caps (NSW $1.5M, Melbourne $950K, Brisbane/Canberra $1M, Adelaide $900K, Perth $850K, Hobart $700K, Darwin $750K). FHBs who buy under those caps with at least 5% deposit pay zero LMI because the federal government guarantees the remaining gap to the lender. FHBs above the price cap (e.g. a $1.6M Sydney purchase) still pay LMI on the standard rules.
Did the 5% Deposit Scheme make LMI obsolete?
For most Australian first home buyers, effectively yes, but only within the state property price caps. The 5% Deposit Scheme (formerly First Home Guarantee) is a federal LMI-replacement guarantee that became uncapped and income-cap-free from 1 October 2025. For buyers under the cap, LMI is no longer the right question, scheme eligibility is. For buyers above the cap (luxury suburbs, larger homes) or buying as investment property, LMI still applies on the standard 1-5% of loan amount sliding scale. Run both paths in the calculator above to see which applies.
How much LMI on a $600,000 loan?
LMI on a $600,000 loan ranges roughly from $4,000 to $25,000 depending on your LVR. At 85% LVR (15% deposit): approximately $6,000-$10,000. At 90% LVR (10% deposit): approximately $13,000-$18,000. At 95% LVR (5% deposit): approximately $20,000-$25,000. Some states also charge insurance duty on the LMI premium itself (VIC about 10%, QLD about 9%) which can add a few hundred dollars; NSW does not charge duty on LMI. The calculator above gives a state-specific estimate using the Helia (formerly Genworth) and QBE published rate bands. First home buyers under the 5% Deposit Scheme caps typically pay zero LMI instead, see the FHB callout in the result panel.
Is LMI tax deductible in Australia?
LMI is generally NOT tax deductible on your own home (owner-occupied property) because the underlying loan is for a private asset. LMI on an INVESTMENT property loan is tax deductible, but the deduction is spread over 5 years or the term of the loan, whichever is shorter, not claimed in one financial year. Capitalised LMI (added to the loan balance) follows the same rule, with the interest on the capitalised amount also deductible on investment loans only. Talk to your accountant before assuming a deduction; the treatment changed in 2017 to limit second-hand asset depreciation alongside LMI.
