Lenders Mortgage Insurance guide
This guide explains how LMI works, the real costs at different deposit levels, when paying LMI makes sense versus waiting to save more, and the government schemes and other alternatives that can help you avoid it altogether.
Quick summary: LMI is a one-off fee you pay when your deposit is less than 20% of the property value. It protects the lender (not you) if you default. On a $500,000 property with a 5% deposit, LMI can cost $15,000 to $25,000. It is typically added to your loan, meaning you pay interest on it over 25 to 30 years. Alternatives include the Home Guarantee Scheme (5% deposit, no LMI), the Help to Buy Scheme (2% deposit, no LMI), and guarantor loans.
What is Lenders Mortgage Insurance?
Lenders Mortgage Insurance (LMI) is a one-off fee paid when a borrower's deposit is less than 20% of the property's value. The borrower pays the fee, but the insurance protects the lender, not you. If you default on your loan and the property is sold for less than what you owe, the lender's LMI provider covers the shortfall. However, the insurer may then pursue you to recover that amount.
LMI is typically capitalised onto your loan, meaning it is added to the total loan amount rather than being paid out of pocket at settlement. This means you pay interest on the LMI premium over the entire life of your loan, which can effectively double the real cost of the insurance. Understanding your Loan to Value Ratio (LVR) is the key to understanding when LMI applies and how much it costs.
How does LMI work?
When you purchase a property with a deposit smaller than 20%, the lender requires LMI to protect against potential loss if you default. The insurance premium is calculated based on your loan amount and your LVR, and it is typically added to your loan at settlement. You then pay interest on this premium over the entire duration of your loan.
It is critical to understand that if you default and your property is sold for less than the outstanding loan amount, the lender claims the shortfall from the LMI provider. The insurer may then pursue you personally for that amount. LMI does not protect you as the borrower or any guarantor. It only protects the lender. If you want protection for yourself in case of illness, injury, or job loss, you need separate mortgage protection insurance or income protection insurance. Understanding your options when choosing the right finance includes considering these personal protection products alongside your loan structure.
Understanding LMI costs
The cost of LMI depends on your loan amount and your deposit size. The lower your deposit, the higher the LMI fee. This single fee is added to your loan and capitalised, meaning you pay interest on it throughout your loan term.
On a $500,000 property with a 5% deposit ($25,000), LMI can cost between $15,000 and $25,000 depending on your lender and circumstances. On the same property with a 10% deposit ($50,000), LMI drops to approximately $8,000 to $15,000. With a 15% deposit ($75,000), it reduces further to approximately $5,000 to $9,000. On an $800,000 property with a 10% deposit, LMI can reach $13,000 to $24,000.
Because these amounts are capitalised onto your loan, you pay interest on them over 25 to 30 years, which can effectively double the real cost. On a $20,000 LMI premium at 6% interest over 30 years, you would pay approximately $23,000 in additional interest, making the true cost closer to $43,000. Use our mortgage repayment calculator to see how LMI affects your monthly repayments, and our property deposit calculator to compare different deposit scenarios.
Paying LMI versus saving a larger deposit
This is one of the most important financial decisions for prospective homeowners. Both options have genuine advantages.
Advantages of paying LMI and buying sooner
You can enter the property market years earlier than if you waited to save a full 20% deposit, allowing you to start building equity immediately. If property values increase while you are saving, the additional growth may outweigh the cost of LMI. Owning sooner means you stop paying rent, potentially saving thousands over the years you would have waited. Every mortgage payment contributes to building equity in your property, creating a tangible asset for your future.
Advantages of waiting to save 20%
Saving a 20% deposit eliminates LMI entirely, potentially saving thousands across your loan term. A larger deposit means borrowing less, reducing your overall interest payments over 25 to 30 years. Loans with lower LVRs often qualify for more competitive interest rates. And larger deposits mean smaller monthly repayments, providing financial flexibility for unexpected expenses. Our budgeting guide helps you assess what you can realistically afford.
The right choice depends on your personal circumstances, financial goals, current rent costs, and the property market in your area. In a rising market, the cost of waiting can exceed the cost of LMI. In a flat or declining market, saving a larger deposit may be the better strategy. A consultation with our team can help you analyse these factors using real numbers from your situation. Start by securing pre-approval to understand your borrowing capacity.

Alternatives to Lenders Mortgage Insurance
Before committing to LMI, explore these alternatives that may better suit your circumstances.
Home Guarantee Scheme (5% deposit, no LMI)
The Home Guarantee Scheme allows eligible first home buyers to purchase with just a 5% deposit without paying LMI. The government guarantees up to 15% of the property value to your lender. This can save you $15,000 to $65,000+ in LMI depending on the property price. Check the benefits and risks to see if you qualify, and review the genuine savings requirements to prepare your deposit.
Help to Buy Scheme (2% deposit, no LMI)
The Help to Buy Scheme allows eligible buyers to purchase with just a 2% deposit, with the government contributing up to 40% equity on new homes. This dramatically reduces your loan amount and eliminates the need for LMI entirely.
Guarantor loans
A family guarantor can use their property equity as additional security for your loan, effectively reducing your LVR in the eyes of the lender. This can eliminate the need for LMI even with a small deposit of your own.
Government grants and concessions
While these do not directly replace LMI, programmes like the NSW First Home Owner Grant ($10,000 on new homes), stamp duty concessions, and the First Home Super Saver Scheme can help you build a larger deposit faster, potentially reducing or eliminating the need for LMI. Our deposit options guide covers every pathway available.
Professional LMI waivers
Some lenders waive LMI for borrowers in certain professions such as medicine, law, and accounting. If you work in a recognised profession, this can save you the entire LMI cost while still allowing you to purchase with less than 20% deposit.
How LMI applies to different property types
LMI requirements and premiums can vary depending on the type of property you are purchasing. High-density strata apartments, particularly those under 40 square metres, may attract higher LMI premiums or stricter LVR requirements because lenders consider them higher risk. Freestanding houses typically receive standard LMI treatment. Rural properties and vacant land with construction contracts may have different LMI requirements depending on the lender's risk assessment of the location.
Whether you buy through private treaty, auction, or off the plan, LMI applies in the same way based on your LVR. The bank valuation determines the property value used to calculate your LVR, and our property purchase and valuation guide explains how this process works. Our guide on how to buy the right property and location, condition, and vibes can help you choose a property that meets both your lifestyle needs and your lender's requirements.
Frequently asked questions
Can I negotiate the cost of LMI?
The LMI premium itself is generally non-negotiable, as it is set by the insurer based on your loan amount and LVR. However, you may be able to have the premium reduced or waived under certain circumstances, such as having a strong borrowing profile or qualifying for professional packages. A mortgage broker can identify which lenders offer the best LMI terms for your situation.
Is LMI tax deductible?
For owner-occupiers, LMI is not tax deductible. If you are purchasing an investment property, the LMI premium may be tax deductible over a number of years. Tax laws are complex, so always consult with a tax professional for advice specific to your situation.
Can I pay LMI upfront instead of capitalising it?
Yes. Most lenders give you the option to pay the LMI premium upfront rather than adding it to your loan amount. Paying upfront means you will not pay interest on the premium over the life of your loan, potentially saving you significant money. Use our mortgage repayment calculator to compare the cost of capitalising LMI versus paying upfront.
Does LMI cover me if I cannot make my repayments?
No. LMI only protects the lender, not the borrower. If you are concerned about meeting repayments due to illness, job loss, or other circumstances, you should consider separate mortgage protection insurance or income protection insurance instead.
Will I need to pay LMI again if I refinance?
If you refinance and your LVR is still above 80%, you will typically need to pay LMI again with your new lender. Some lenders may offer LMI portability or transfer options, but these are not widely available. This is an important cost to factor in when deciding whether to refinance.
How does the Home Guarantee Scheme compare to paying LMI?
The Home Guarantee Scheme allows eligible first home buyers to purchase with a 5% deposit without paying LMI, potentially saving $15,000 to $65,000+. The scheme has eligibility requirements and property price caps. Read the benefits and risks to compare with paying LMI for your specific situation.
Can I avoid LMI with a guarantor loan?
Yes. A guarantor loan uses the equity in your guarantor's property as additional security, effectively reducing your LVR in the eyes of the lender. This can eliminate the need for LMI even with a small deposit. Guarantor arrangements are a popular strategy, particularly when family members want to support each other's property purchase.
Does LMI apply to all property types?
LMI requirements can vary based on property type. Some high-density apartments, rural properties, or unique property types may have stricter LVR requirements or higher LMI premiums due to perceived higher risk. Your lender and broker can advise on how the property you are considering affects your LMI costs.
Will a higher income help me avoid LMI?
A higher income does not directly exempt you from LMI. LMI is determined by your LVR, not your income. However, a higher income may help you qualify for professional packages that include LMI waivers if you work in recognised professions such as medicine, law, or accounting.
How can I calculate my potential LMI costs?
Most major lenders provide online LMI calculators based on your deposit amount and property value. For the most accurate assessment, a mortgage broker can provide quotes from multiple lenders and help you understand the true cost of LMI across your entire loan term. Use our home equity calculator and property deposit calculator to explore different scenarios.
