The Basics
What Is Lenders Mortgage Insurance?
Lenders Mortgage Insurance (LMI) is a one-off insurance premium that Australian lenders charge when a borrower's deposit is less than 20% of the property's purchase price. The policy protects the lender — not the borrower — against financial loss if the borrower defaults and the property sells for less than the outstanding loan balance.
LMI exists because loans with smaller deposits carry higher risk for the lender. Without this insurance, most banks and non-bank lenders would not approve home loans above 80% of the property value. In practice, LMI enables hundreds of thousands of Australians to enter the property market earlier than they otherwise could — but at a significant cost that many borrowers don't fully understand before they commit.
The insurance is provided by specialist underwriters regulated by APRA rather than the lenders themselves. Australia's three LMI providers are QBE Lenders' Mortgage Insurance, Helia (formerly Genworth Financial), and Arch Lenders Mortgage Insurance. Each lender has arrangements with one or more of these insurers, and borrowers cannot choose their provider.
Who Does LMI Actually Protect?
LMI protects the lender against the risk of borrower default. If a borrower stops making repayments and the lender sells the property at a loss, the insurer reimburses the lender for the gap between the sale price and the remaining loan balance.
This is the most commonly misunderstood aspect of LMI. Despite paying the premium, the borrower receives no protection from the policy. If the property sells for less than what is owed, the borrower may still be pursued by the insurer for the remaining shortfall — a concept known as shortfall debt.
Key takeaway
Despite paying the premium, the borrower receives no protection from LMI. If the property sells for less than what is owed, the insurer can pursue the borrower for the remaining shortfall.
When Is LMI Required?
LMI is triggered when the loan-to-value ratio (LVR) exceeds 80%. LVR is calculated by dividing the loan amount by the property's value, then multiplying by 100.
LVR = (Loan Amount ÷ Property Value) × 100
For example, borrowing $720,000 against an $800,000 property gives an LVR of 90%. Since this exceeds the 80% threshold, LMI applies.
20%+ deposit — No LMI required
Less than 20% deposit — LMI applies
| Deposit | LVR | LMI Status |
|---|---|---|
| 20% or more | 80% or below | No LMI required |
| 15% | 85% | LMI applies |
| 10% | 90% | LMI applies — higher premium |
| 5% | 95% | LMI applies — highest premium |
Some lenders apply LMI at slightly different thresholds. The 80% LVR rule is the industry standard, but borrowers should confirm the exact threshold with their lender or broker.
The Real Cost
How Much Does LMI Cost?
LMI premiums range from a few thousand dollars to more than $50,000 depending on the loan amount and LVR. The premium is a one-off charge calculated at the time of loan approval, not an ongoing monthly fee. You can use our LMI calculator to estimate your exact cost.
| Property Price | Deposit | Loan Amount | LVR | Estimated LMI |
|---|---|---|---|---|
| $600,000 | 10% ($60K) | $540,000 | 90% | $8,200 |
| $600,000 | 5% ($30K) | $570,000 | 95% | $21,400 |
| $800,000 | 10% ($80K) | $720,000 | 90% | $12,400 |
| $800,000 | 5% ($40K) | $760,000 | 95% | $33,600 |
| $1,000,000 | 10% ($100K) | $900,000 | 90% | $16,800 |
| $1,000,000 | 5% ($50K) | $950,000 | 95% | $45,200 |
| $1,500,000 | 5% ($75K) | $1,425,000 | 95% | $52,000+ |
Indicative costs based on typical QBE and Helia premiums for owner-occupied, principal & interest loans. Actual costs vary by lender and insurer.
What Factors Affect the LMI Premium?
Five variables determine the exact LMI cost for a given loan:
Loan-to-Value Ratio
The primary driver. Each LVR band (80–85%, 85–90%, 90–95%) has a different premium rate. The jump from 90% to 95% LVR is particularly steep — often doubling or tripling the premium.
Loan amount
Higher loan amounts attract higher absolute premiums. A $1M loan at 90% LVR costs significantly more in LMI than a $500K loan at the same ratio.
Loan purpose
Owner-occupied loans generally attract lower premiums than investment property loans. Some insurers apply a loading of 10–20% for investment lending.
Loan type
Principal and interest loans receive standard pricing. Interest-only loans may attract a loading because they don't reduce the loan balance during the interest-only period.
LMI insurer
QBE, Helia, and Arch each have their own premium schedules. The difference between insurers can be several thousand dollars on the same loan — but borrowers don't get to choose.
How Do You Pay for LMI?
Borrowers typically have two options for paying the LMI premium. Each approach has different long-term cost implications.
Upfront at Settlement
Pay the full premium as a lump sum. No interest accrues on it. This is the cheaper option over the life of the loan, but requires additional cash at settlement.
Capitalised onto the Loan
Added to your loan balance. Avoids the upfront cash outlay but means paying interest on the LMI premium for the entire loan term.
The hidden cost of capitalising LMI
A capitalised premium of $16,800 at 6.5% interest over 30 years adds approximately $21,400 in interest charges alone. The true cost of that LMI premium becomes $38,200 — more than double the original amount.

Refunds
Is LMI Refundable?
LMI refunds are possible in limited circumstances, typically when the loan is discharged within the first few years. The refund is partial and decreases over time.
- Timeframe: Refunds are usually only available if the loan is repaid or refinanced within the first 12 to 24 months.
- Loan discharge required: The original loan must be fully repaid through sale, refinancing, or lump sum repayment.
- Application process: Refunds are not automatic. The borrower or broker must apply through the original lender.
- Administration fees: Some lenders charge a processing fee that reduces the net refund amount.
As a general guide, a loan discharged within 12 months might receive a 40–50% refund, while one discharged at 18–24 months might receive 10–25%. Beyond 24 months, refunds are rare.
If you're considering refinancing an existing loan that had capitalised LMI, the savings from removing mortgage insurance through a professional waiver will typically outweigh any potential LMI refund — particularly if the original loan is more than two years old.
Your Options
How to Avoid Paying LMI
There are five main strategies for purchasing a property without paying Lenders Mortgage Insurance. Each has different trade-offs.
Save a 20% deposit
The most straightforward approach: if your LVR is 80% or below, LMI does not apply. On an $800,000 property, this means saving $160,000. You can compare deposit options to understand the trade-offs. The practical challenge is time — at $2,000 per month, reaching a $200,000 deposit takes more than eight years, during which property prices may rise faster than the deposit grows.
Use a family guarantee
A guarantor — typically a parent — uses equity in their own property to secure a portion of the borrower's loan. This reduces the lender's risk below the LMI threshold without the borrower needing a full 20% deposit. The risk: if the borrower defaults, the guarantor's property may be used to cover the shortfall.
First Home Guarantee (government scheme)
The Australian Government's First Home Guarantee allows eligible first home buyers to purchase with as little as 5% deposit without paying LMI. Eligibility is limited to first home buyers under an income threshold ($125,000 for individuals, $200,000 for couples) purchasing below regional price caps.
Professional LMI waivers
Certain Australian lenders waive the LMI requirement entirely for borrowers employed in approved professional occupations — allowing them to borrow up to 90% LVR without paying LMI. More than 30 professions qualify, including:
- Medical: Doctors, dentists, veterinarians, optometrists, pharmacists
- Legal & financial: Lawyers, accountants, actuaries, financial planners
- Engineering & IT: Engineers, IT professionals, surveyors, architects
- Government & emergency: Police officers, paramedics, public servants, defence personnel
- Education & health: Teachers, nurses, physiotherapists, psychologists
Lender risk fees as an alternative
A small number of lenders offer their own alternative to LMI — sometimes called a lender's risk fee. Rather than purchasing external insurance, the lender self-insures and charges a smaller fee directly. These fees are typically lower than traditional LMI premiums but are only available through select lenders.
Common Confusion
LMI vs Mortgage Protection Insurance
Lenders Mortgage Insurance and mortgage protection insurance are entirely separate products that serve different purposes. Confusing the two is common among first-time borrowers.
| LMI | Mortgage Protection | |
|---|---|---|
| Protects | The lender | The borrower |
| Triggered by | Borrowing above 80% LVR | Illness, injury, or job loss |
| Premium | One-off (paid by borrower) | Ongoing monthly |
| Mandatory? | Yes, if LVR exceeds 80% | No — entirely optional |
| Provider | QBE, Helia, Arch | General insurers |
| Benefit | Covers lender's loss on default | Covers borrower's repayments |
Other insurance products borrowers sometimes confuse with LMI include home and contents insurance (protects the physical property), life insurance (pays a lump sum on death), and income protection insurance (replaces a percentage of income during incapacity). None of these interact with or substitute for LMI.
The Trade-Off
Pros and Cons of Paying LMI
Potential Benefits
- Enter the market sooner — buying earlier in a rising market can result in greater equity growth
- Preserve savings — keep cash in reserve for renovations, moving costs, or emergencies
- Opportunity cost — money in a larger deposit could earn returns elsewhere
Drawbacks
- Significant cost with no borrower benefit — $10,000–$50,000+ for insurance you can't claim on
- True cost doubles when capitalised — interest compounds over the life of the loan
- Non-refundable after 12–24 months
- Shortfall liability remains — the insurer can pursue you for remaining debt
For borrowers who qualify for a professional LMI waiver, the decision is straightforward: the waiver provides the same benefit of entering the market with a smaller deposit, without the premium cost.
Worst Case
What Happens If You Default on Your Loan?
If a borrower defaults — meaning they cannot meet their repayment obligations — the lender follows a structured recovery process. LMI plays a specific role in this sequence.
Hardship and arrears
The lender first attempts to work with the borrower through hardship provisions, repayment modifications, or temporary forbearance. Default doesn't happen overnight — it typically involves months of missed payments.
Possession and sale
If the borrower cannot resume repayments, the lender may exercise its right to take possession of the property and sell it. The sale proceeds are applied to the outstanding loan balance.
Shortfall claim
If the sale price is less than the amount owed (including accrued interest, fees, and selling costs), the lender lodges a claim with the LMI insurer for the shortfall.
Insurer pays the lender
The LMI policy compensates the lender for the difference. At this point, the lender's loss is covered.
Subrogation — insurer pursues the borrower
The insurer now holds the right to recover the shortfall amount from the borrower. This is called subrogation. The borrower's debt doesn't disappear — it transfers from the lender to the insurer.
Important
LMI does not remove the borrower's liability. In the worst-case scenario, the borrower is left with no property and a remaining debt to the insurer. The borrower may face legal action, debt collection, or bankruptcy proceedings.
