What is LMI and how do you avoid it?

What is LMI?

LMI protects the lender, and the premium is usually paid by the borrower. It is commonly required above 80% of the lender-assessed property value, subject to the lender’s product and any approved guarantee or waiver.

LMI is usually a one-off premium. Confirm payment timing and whether the lender allows it to be added to the loan; financing the premium also creates interest costs.

Your lender arranges cover or another product-specific risk charge. Ask which insurer or arrangement applies and request an itemised quote. Calcy does not compare or quote insurer-specific premiums.

Who does LMI protect?

This is the most important thing to understand about LMI: it protects the lender, not you.

If you default on your loan and the bank repossesses and sells your property for less than the outstanding loan balance, LMI covers the lender's loss. You, as the borrower, remain liable for any shortfall even after an LMI claim is paid — the insurer may still pursue you for the difference.

The borrower usually bears the premium. The requirement and amount depend on the lending arrangement, not deposit percentage alone.

When does LMI apply?

LMI is commonly required above 80% LVR, but the lender’s valuation, government guarantees and product-specific waivers can change the requirement. LVR is calculated as:

LVR = Loan amount ÷ Property value × 100

A $595,000 loan against a lender-valued $700,000 home has 85% LVR. This does not, on its own, determine whether the lender requires LMI.

Within Calcy’s illustrative bands, a higher LVR can increase the premium estimate. An actual quote also depends on the lender, insurer, loan size, product and any waiver.

Maximum LVR depends on the lender, property, security and borrower. Higher-LVR products do not establish automatic approval or eligibility for a waiver.

How much does LMI cost?

LMI is not a fixed fee — it varies based on:

• Your loan amount
• Loan-to-value ratio and the product’s pricing bands
• The lender and insurer they use
• Whether you are an owner-occupier or investor

Calcy uses illustrative premium bands, a model allowance of 10% and rounding to the nearest $100. These are not insurer quotes or verified state insurance-duty rates. Actual premiums, charges, capitalisation limits and waivers depend on the lender and insurer. First-home-buyer status alone does not remove the model premium.

How LMI is calculated — real examples

At a $650,000 lender valuation, a 10% deposit is $65,000, leaving a $585,000 loan and 90% LVR. A 15% deposit is $97,500, leaving $552,500 and 85% LVR.

Calcy’s owner-occupier model returns $7,700 and $4,000 respectively, using its published illustrative bands, 10% allowance and nearest-$100 rounding. The $3,700 difference is a model comparison, not an insurer quote or guaranteed saving.

Calcy uses illustrative premium bands, a model allowance of 10% and rounding to the nearest $100. These are not insurer quotes or verified state insurance-duty rates. Actual premiums, charges, capitalisation limits and waivers depend on the lender and insurer. First-home-buyer status alone does not remove the model premium.

Can LMI be added to your loan?

Some lenders permit capitalisation: adding the premium to the loan. Check the written conditions and maximum lending limit rather than assuming the premium can always be financed.

While this means you don't need to pay the premium in cash at settlement, it does increase your total loan balance and the total interest you'll pay over the life of the loan. A $12,000 LMI premium capitalised into a 30-year loan at 6% will cost you significantly more than $12,000 by the time the loan is paid off.

Four strategies to avoid LMI

1. Save a 20% deposit

A 20% deposit commonly avoids LMI if the lender valuation supports 80% LVR. Confirm the actual requirement and allow for purchase costs separately.

The trade-off is time. Saving a 20% deposit on a $700,000 home ($140,000) takes considerably longer than a 10% deposit ($70,000), and property prices may rise in the interim.

2. Use a guarantor loan

A family guarantee can provide additional security that may avoid LMI. It does not change the loan divided by the value of the purchased property. A guarantor puts their own assets at risk; seek independent legal advice and written lender conditions.

A lender must assess the proposed guarantee, security and servicing before confirming whether LMI is waived. Do not assume a guaranteed portion creates automatic approval.

Guarantor loans carry risks for the guarantor — if you default, the lender can pursue their property. This arrangement should be entered into carefully and with independent legal advice for all parties.

3. Use a profession-based LMI waiver

Occupation-based waivers are lender-specific. The occupations below are examples to ask about, not a verified eligibility list:

• Medical doctors and specialists
• Dentists and other healthcare professionals
• Lawyers and barristers
• Accountants (CPA/CA qualified)
• Some engineers and architects

Eligibility criteria, maximum loan amounts, and LVR limits vary by lender. If you work in one of these fields, it's worth specifically asking your lender or broker whether you qualify.

4. Access government schemes

From 1 October 2025, the Australian Government's 5% Deposit Scheme allows eligible first home buyers to purchase with as little as a 5% deposit without paying LMI, with no income caps and no waitlist. Housing Australia provides a guarantee over part of an eligible home loan; this is not a cash contribution to your deposit.

Key programs within the scheme include:

• Australian Government 5% Deposit Scheme: no annual place limit or income caps from 1 October 2025
• Regional buyers now use the expanded Australian Government 5% Deposit Scheme; the separate regional scheme closed on 1 October 2025
• Single-parent and legal-guardian pathway: minimum 2% deposit, subject to current scheme eligibility

Property price caps still apply and vary by state and by capital city vs. regional area — check the current cap for your area before relying on this scheme.

Is LMI ever worth paying?

In some situations, paying LMI makes financial sense rather than waiting to save a larger deposit. Consider the following scenarios:

Rising property market: If property prices in your target area are rising faster than you can save, waiting to avoid LMI may cost you more in additional property price appreciation than the LMI premium itself. For illustration only, 8% annual growth would turn a $700,000 home into $756,000 in twelve months. This is not a forecast.

Cost of waiting: Compare rent while saving with LMI, interest, ownership expenses and the savings buffer you would retain. Rent versus the premium alone is not enough to decide whether buying sooner is affordable.

In a stable market, waiting may reduce the premium and loan size, but additional rent and other costs still matter.

There is no universal answer — the right choice depends on your personal savings rate, local market conditions, and your timeline.

Key takeaways

• LMI protects the lender, not you — but you pay the premium
• LMI is commonly required above 80% LVR; guarantees and lender-specific exceptions can apply.
• Calcy premiums are illustrative model outputs, not insurer quotes; obtain a lender quote.
• LMI may be added to the loan subject to lender limits; borrowing it creates interest costs.
• Four main ways to avoid LMI: 20% deposit, guarantor loan, profession waiver, or government scheme
• In some market conditions, paying LMI and buying sooner can be the smarter financial decision

Frequently asked questions

Is LMI the same as mortgage protection insurance?

No. These are two completely different products. LMI protects the lender if you default. Mortgage protection insurance is a separate optional product. Any benefit depends on its policy wording, exclusions and claim conditions; it does not guarantee that every income interruption is covered.

Do I get my LMI refunded if I sell the property?

A refund is not automatic. Ask your existing lender whether a partial LMI refund is available when switching or repaying early; eligibility depends on the policy and lender. ASIC Moneysmart recommends asking about a refund when switching. A new lender may require a new premium.

Does LMI transfer to a new lender if I refinance?

Do not assume the old policy transfers. A new lender may require a new premium, depending on its valuation, product and any waiver. Obtain a written quote and ask the existing lender about a possible partial refund.

Can I claim LMI as a tax deduction?

LMI associated with an income-producing loan may be a borrowing expense. The deductible portion and timing depend on the loan’s use and ATO rules. Do not assume a personal home-loan premium is deductible; check the ATO borrowing-expenses guidance or obtain tax advice.

What happens to LMI if I pay down my loan below 80% LVR?

A refund is not automatic. Ask your existing lender whether a partial LMI refund is available when switching or repaying early; eligibility depends on the policy and lender. ASIC Moneysmart recommends asking about a refund when switching. A new lender may require a new premium.
