Lenders Mortgage Insurance (LMI): Costs and Options
Understand lenders mortgage insurance (LMI), who it protects, how premiums affect borrowing and which deposit, guarantee or waiver options to compare.

Lenders mortgage insurance (LMI) protects the lender against a loss if a borrower defaults and selling the property doesn’t repay the debt. The borrower usually pays the cost, but the policy doesn’t cover their repayments or cancel what they owe.
LMI can help a buyer purchase with a smaller deposit. Its cost depends on the proposed loan and the lender’s insurance arrangements, so a deposit percentage alone can’t tell you the premium. Compare a dated quote with the cash, timing and security requirements of other purchase routes.
What Lenders Mortgage Insurance Covers
LMI covers the lender’s insured loss when a borrower defaults and the property sale leaves an unpaid balance, called a shortfall. The lender arranges the cover and makes any claim. Moneysmart’s LMI definition explains who the insurance protects.
The borrower’s debt can continue after an insurance claim. Helia’s LMI factsheet, available as at October 2026, explains that the insurer may recover the outstanding debt from the borrower. Paying for LMI doesn’t buy a right to stop repayments.
In a hypothetical example, the debt and sale costs total $520,000 and the property sells for $490,000. The $30,000 shortfall can become the subject of an insurance claim under the policy. The borrower can still face recovery of that debt.
Lender Approval and Insurance Approval
The lender decides whether the loan meets its lending criteria. Where insurance is required, the insurer also assesses whether the proposal qualifies for cover. An estimated premium is a cost calculation, not either party’s approval.
Helia’s underwriting guidance lists guidelines effective 10 August 2026 for submitting insurance proposals. An application outside those guidelines can receive an individual assessment. That possibility doesn’t guarantee an exception or approval.
Mortgage Insurance and Repayment Protection
In Australian home lending, “mortgage insurance” commonly means LMI. Mortgage protection insurance is a separate product that can cover the borrower for specified events, subject to its policy terms. Income protection and life insurance also have their own purposes and exclusions.
An incorrect explanation is, “LMI will pay your repayments if you lose your job.” The correct explanation is, “LMI covers the lender’s insured loss after default.” Use the separate mortgage protection insurance guide for questions about borrower cover.
When Mortgage Insurance Enters the Assessment
LMI commonly enters the assessment when the loan exceeds 80% of the property’s value. Moneysmart describes this as the usual threshold, so treat it as a starting point for assessment rather than a requirement for every loan.
The loan-to-value ratio (LVR) is the loan amount divided by the lender’s accepted property value, multiplied by 100. A larger deposit generally means a lower LVR. The maximum LVR guide explains how lenders assess the ratio and their lending limits.
This hypothetical table uses a $600,000 property, with the purchase price equal to the accepted value. It excludes buying costs and any premium added to the loan.
| Deposit | Cash deposit | Base loan | LVR before LMI |
|---|---|---|---|
| 5% | $30,000 | $570,000 | 95% |
| 10% | $60,000 | $540,000 | 90% |
| 15% | $90,000 | $510,000 | 85% |
| 20% | $120,000 | $480,000 | 80% |
A 5%, 10% or 15% deposit produces different borrowing ratios, but none fixes an LMI price. At 85% or 90% LVR, an eligible guarantee or waiver can change whether a premium is payable. Occupation alone doesn’t establish eligibility.
The lender’s valuation can also change the result. In a hypothetical purchase at $600,000, a $540,000 base loan is 90% of that price. If the lender accepts a value of $580,000, the same loan is about 93.1% LVR.
A broker assesses the proposed product alongside income, debts, credit history and evidence of the deposit. The insurer’s requirements can add conditions concerning the borrower or security. Paying LMI doesn’t overcome an unaffordable loan or an unacceptable property.
Estimate and Explain the Premium
Calculate LMI through the proposed lender’s quote or an insurer estimator using the actual loan assumptions. There isn’t one Australian mortgage insurance rate that you can multiply by every loan. A cheap premium also doesn’t establish the cheapest home loan once interest and other fees are included.
Helia’s fee estimator, as at October 2026, asks for property value, deposit, first-home-buyer status, loan term and occupancy type. Helia says the final premium can change with the loan purpose, borrower type, security type or updated application information.
Prepare the following information for a lender quote.
- Identify the lender, proposed product and purchase or refinance purpose.
- State the requested loan and the value the lender accepts for the property.
- Record the deposit amount, its source and the cash reserved for purchase costs.
- Include occupancy, borrower details and the proposed security.
- Specify the term and whether the premium will be paid separately or added to the loan.
- Identify any discount, guarantee or waiver being assessed.
Record what the quoted total includes. Helia’s estimator displays premiums including goods and services tax (GST), excluding stamp duty.
For property in New South Wales, Queensland, Victoria or Western Australia, use the relevant location and tax treatment in the quote. A quote prepared for one state isn’t a national premium table.
Upfront Payment or Capitalisation
Paying an upfront premium uses cash at settlement. Capitalisation adds the premium to the loan, if the lender approves that structure. Helia’s payment information describes both options, as at October 2026, and says availability depends on the lender.
For the hypothetical $600,000 property with a 10% deposit, the base loan is $540,000. If you pay the quoted premium separately, that premium adds to the cash needed at settlement. If the lender permits full capitalisation, the starting balance is $540,000 plus the quoted premium.
The larger balance increases repayments and interest paid over the time the premium remains borrowed. The lender must assess that balance against its LVR limit and repayment-affordability rules.
Ask for the comparison on the same interest rate, term and repayment basis so the extra borrowing cost is visible.
LMI is usually charged once for the loan. A capitalised premium is repaid through the mortgage and incurs interest while outstanding. Helia also describes monthly payment arrangements for some lenders, so a one-off payment isn’t the only possible structure.
Early Repayment, Refunds and Refinancing
An early payout can qualify for a partial refund under the applicable policy and lender terms. Helia’s general information, as at October 2026, shows potential refunds of 40% within the first year and 20% during years one to two. Eligibility depends on the policy, and missed repayments or default can exclude a refund.
Helia’s cancellation guidance also says some arrangements exchange refund rights for a larger upfront discount. Direct a cancellation or refund request to the lender, which can identify the arrangement for the actual loan.
National Australia Bank (NAB) publishes a different rule for newer loans, as at October 2026. For settlement or drawdown on or after 10 June 2024, NAB’s refund terms provide 40% when the loan is repaid and closed within 12 months. After 12 months, those loans receive no premium refund.
NAB lists different refund terms for loans settled from 25 November 2019 to 9 June 2024. The settlement date therefore matters as well as the insurer’s name.
NAB also says its LMI isn’t transferable to another financial institution. A refinance can require a new premium if the new lender requires insurance. Include any confirmed old-loan refund and the new-loan premium separately in the switching calculation.
Compare Paying LMI With Other Routes
A larger deposit, an eligible government scheme, family security support or a verified lender waiver can change the cost of purchasing. The useful choice depends on when the buyer needs to purchase and which risks they can accept.
| Route | Effect on purchase funding | Constraint to weigh |
|---|---|---|
| Pay LMI | Can support a smaller deposit where the loan qualifies | Premium, interest if capitalised and a higher debt balance |
| Save a larger deposit | Reduces the loan and can avoid a premium | Time spent saving, housing costs during the wait and cash left after purchase |
| Eligible government guarantee | Can remove LMI for a qualifying scheme loan | Eligibility, property price cap, participating lender and ongoing obligations |
| Family guarantee | Uses additional family security under the lender’s rules | The guarantor’s financial exposure and requirements for later release |
| Verified waiver | Removes the premium under the lender’s eligibility rules | Borrower, product and lending-limit conditions |
As at October 2026, the Australian Government 5% Deposit Scheme allows eligible buyers to purchase with a minimum 5% deposit without LMI. The first-home-buyer route requires owner-occupation, a property within the location price cap and a participating lender. The buyer must still meet that lender’s credit criteria.
A government guarantee reduces the lender’s risk while the borrower remains responsible for the loan. It doesn’t pay the buyer’s deposit or mortgage repayments. Loss of ongoing scheme eligibility can also create additional costs.
A family guarantor can use property or savings to support the loan. Moneysmart’s guarantor guidance explains the risk to that person’s finances and security. Compare the proposed guarantee amount and release conditions through the home loan guarantor guide.
A waiver needs a separate eligibility assessment. Job title, professional registration, income and the proposed loan can affect the result, depending on the lender. The LMI waiver guide explains that assessment without treating an occupation as automatic approval.
Brokers can use Bulma’s Policy Advisor to compare lender-specific LMI and guarantee rules across 52+ lenders. Bulma quotes the policy behind each answer, so the broker can retain the wording with the comparison. The lender supplies the premium quote and final loan decision.
Record the Explanation in the Credit File
Keep the dated premium quote with the assumptions and the borrower’s chosen funding route. The record must show why the quoted cost applies to this loan and what the client understands about the cover.
Use a file note that another broker can follow without reconstructing the conversation.
- Record the lender, insurer where known, product and quote date, including its validity period if supplied.
- Keep the accepted valuation, deposit source, base loan and LVR calculation.
- State the premium, included taxes, settlement cash requirement and any capitalised balance.
- Retain the comparison of available alternatives, including repayment and total-cost assumptions.
- Record the client’s questions and the explanation that LMI protects the lender and doesn’t remove the borrower’s debt.
- Keep the refund terms for this loan and any guarantee or waiver approval relied on.
Recalculate and obtain an updated quote if the loan amount, accepted valuation, product or lender changes before settlement. Reassess any waiver or guarantee if the borrower or security changes. Where capitalisation changes the starting balance, confirm that the approved amount covers settlement before the client relies on the funding plan.
