Lenders Mortgage Insurance Explained

Lenders mortgage insurance, usually called LMI, is one of the most misunderstood costs in Australian property buying.

Many buyers first hear about LMI when they are told their deposit is under 20%.

LMI can help some buyers purchase sooner, but it can also add a significant cost to the loan or purchase.

This guide explains what LMI is, who it protects, when it may apply and what buyers should consider.

What is lenders mortgage insurance?

Lenders mortgage insurance is insurance that protects the lender if the borrower defaults on the loan and the lender suffers a loss after selling the property.

The key point is this:

LMI protects the lender, not the borrower.

Even though the borrower usually pays the LMI premium, the insurance is for the lender's benefit.

Why does LMI exist?

Lenders take more risk when a borrower has a smaller deposit.

If a buyer borrows a high percentage of the property value, there is less equity protecting the lender if the property needs to be sold.

LMI helps reduce the lender's risk when approving higher loan-to-value ratio loans.

What is loan-to-value ratio?

Loan-to-value ratio, or LVR, compares the loan amount to the property value.

Example:

• Property value: $750,000
• Loan amount: $600,000
• LVR: 80%

Another example:

• Property value: $750,000
• Loan amount: $675,000
• LVR: 90%

The higher the LVR, the smaller the buyer's deposit compared with the property value.

Use the PurchaseWise Property Purchase Calculator to test different deposit and LVR scenarios.

When might LMI apply?

LMI is commonly associated with loans above 80% LVR.

For example, a buyer with a 10% deposit may have a 90% LVR before costs. That buyer may need to pay LMI, depending on the lender and loan structure.

However, rules can vary.

LMI may depend on:

• The lender
• The loan amount
• The property value
• The borrower type
• The property type
• The location
• Whether the buyer qualifies for a special scheme
• Whether a guarantor is involved
• Whether the borrower is in an eligible profession

Buyers should always check with their lender or broker.

How is LMI paid?

LMI may be paid in different ways depending on the lender.

It may be:

• Paid upfront at settlement
• Added to the loan amount
• Partly paid upfront and partly capitalised

If LMI is added to the loan, the borrower may pay interest on it over time because it becomes part of the loan balance.

This can make the long-term cost higher than the upfront premium alone.

A simple LMI example

Imagine a buyer wants to purchase a property for $750,000.

Scenario A: 20% deposit

• Deposit: $150,000
• Loan amount: $600,000
• LVR: 80%

LMI may not apply, depending on lender policy.

Scenario B: 10% deposit

• Deposit: $75,000
• Loan amount before costs: $675,000
• LVR: 90%

LMI may apply because the loan is above 80% LVR.

This does not mean Scenario B is always wrong. It simply means the buyer needs to understand the extra cost and risk.

Why some buyers accept LMI

Some buyers choose to pay LMI because it may allow them to buy sooner.

This can be attractive if:

• They have stable income
• They are confident in their budget
• They want to enter the market earlier
• They expect prices to rise
• They do not want to wait years to save a larger deposit

However, paying LMI is still a cost and should be considered carefully.

Why some buyers avoid LMI

Other buyers prefer to avoid LMI by saving a larger deposit.

This may help them:

• Reduce upfront or capitalised costs
• Borrow less
• Reduce repayments
• Improve loan options
• Lower financial pressure
• Start with more equity

The trade-off is that it may take longer to buy.

LMI is not the same as mortgage protection insurance

LMI should not be confused with mortgage protection insurance or income protection insurance.

LMI protects the lender.

Mortgage protection or income protection may help the borrower in certain circumstances, depending on the policy.

Always read insurance documents carefully and seek advice if unsure.

Can LMI be refunded?

In many cases, LMI is not refundable if you refinance, repay the loan early or sell the property.

Some lenders or insurers may have specific rules, but buyers should not assume they will get LMI back.

Ask the lender before proceeding.

Can a guarantor help avoid LMI?

Some buyers use a family guarantee or limited guarantee to reduce the lender's risk and potentially avoid LMI.

This can help some buyers enter the market sooner, but it also creates risk for the guarantor.

A guarantor may be putting part of their own property or financial position at risk.

Guarantor arrangements should be considered carefully with legal and financial advice.

Can first home buyer schemes help?

Some government or lender schemes may help eligible buyers purchase with a smaller deposit and reduced or no LMI.

Eligibility rules can change and may depend on income, property price, location, buyer type and whether the buyer has owned property before.

Buyers should check current rules before relying on a scheme.

How LMI affects repayments

If LMI is added to the loan, the loan balance increases.

A higher loan balance generally means higher repayments and more interest over time.

Questions to ask your broker or lender

• Will LMI apply to this loan?
• How much is the estimated LMI premium?
• Can the premium be added to the loan?
• What will the final loan amount be?
• How will this affect repayments?
• Can I avoid LMI with a larger deposit?
• Are there any eligible first home buyer schemes?
• Would a guarantor structure be suitable?
• Is the property type acceptable at this LVR?
• What happens if I refinance later?

Common mistakes to avoid

Mistake 1: Thinking LMI protects the borrower. LMI protects the lender, not the borrower.

Mistake 2: Comparing only the deposit. A smaller deposit may allow you to buy sooner, but the total cost may be higher.

Mistake 3: Forgetting interest on capitalised LMI. If LMI is added to the loan, it can cost more over time.

Mistake 4: Assuming every lender charges the same LMI. Different lenders and insurers may calculate LMI differently.

Mistake 5: Ignoring the risk of buying with a very small buffer. A high-LVR purchase can leave less room for unexpected repairs, rate rises or changes in income.

Final thoughts

Lenders mortgage insurance can help some buyers purchase property sooner, but it is important to understand what it does and what it does not do.

It protects the lender, not the borrower.

Before accepting LMI, compare the cost, repayment impact, deposit options and alternatives with a qualified broker or lender.
