Private Mortgage Insurance (PMI) can feel like one of those frustrating home-buying costs nobody mentions until you are ready to apply for a mortgage. You save a deposit, find the right house and start comparing home loan rates. Then you discover that borrowing with a smaller deposit may come with an extra charge worth thousands of dollars.
The good news is that Private Mortgage Insurance may be avoidable. Even if you cannot save a 20% house deposit, you may qualify for a government guarantee, professional home loan, family guarantor loan or another low-deposit mortgage option. In Australia, Private Mortgage Insurance is normally called Lenders Mortgage Insurance, or LMI. The names are different, but the basic purpose is similar: the insurance protects the home loan lender, not the borrower.
What Is Private Mortgage Insurance (PMI) in Australia?
Private Mortgage Insurance, commonly known as PMI, is insurance that protects a mortgage lender if a borrower cannot repay their house loan. In Australia, the equivalent product is called Lenders Mortgage Insurance. LMI may be required when you borrow more than 80% of a property’s lender-assessed value. This is known as having a loan-to-value ratio, or LVR, above 80%.
For example, imagine you want to buy a $700,000 home with a $70,000 deposit. You would need to borrow $630,000, giving you an LVR of 90%. Because the LVR is above 80%, the lender may require LMI. According to the Australian Government’s Moneysmart, LMI is usually a one-off cost payable when the amount borrowed exceeds 80% of the property’s value.
Does Private Mortgage Insurance protect the homeowner?
No. Private Mortgage Insurance and Lenders Mortgage Insurance protect the lender rather than the homeowner. That distinction catches many buyers by surprise. You pay the premium, but the insurance is designed to cover the lender if you default and the property is sold for less than the outstanding mortgage debt. Even if an insurer pays the lender for a shortfall, the borrower may still be responsible for that debt. LMI should not be confused with income protection, life insurance or mortgage protection insurance.
How Much Does Private Mortgage Insurance Cost?
There is no single PMI or LMI price that applies to every Australian home loan. The cost can vary according to your deposit, mortgage amount, LVR, property type and the lender’s requirements. A larger loan and higher LVR will generally result in a higher premium. Commonwealth Bank says LMI can generally range from 1% to 5% of the loan amount. It gives the example that LMI on a $500,000 house loan with a 10% deposit could cost more than $10,000. Actual costs will depend on the application and lender.
LMI is often paid at settlement or added to the home loan. Adding it to the mortgage can reduce the amount of cash needed upfront, but it may also mean paying interest on the premium for years.
What affects the cost of PMI or Lenders Mortgage Insurance?
Your loan-to-value ratio is one of the biggest factors. Someone borrowing 85% of a property’s value may pay less LMI than a borrower seeking a 95% home loan.
The total loan amount also matters. A high-LVR mortgage of $900,000 will usually carry a greater insurance cost than a smaller house loan with the same LVR.
The property, loan purpose and lender can also affect the result. Investment home loans, unusual properties and some high-risk locations may be treated differently.
Your eligibility for a lender’s special policy can be important too. Some banks offer LMI waivers to eligible medical, legal, accounting or other professionals.
How Do I Avoid Private Mortgage Insurance on a Home Loan?
The simplest way to avoid Private Mortgage Insurance is to keep your LVR at 80% or below. However, saving a 20% deposit is not the only strategy available. The right option will depend on your income, occupation, eligibility, family support and how quickly you want to buy.
1. Can I avoid Private Mortgage Insurance with a 20% deposit?
In most cases, a deposit of at least 20% of the lender-assessed property value will help you avoid LMI. Remember to budget for stamp duty, conveyancing, inspections and other purchasing costs as well. Using part of your deposit to cover these expenses could push your effective LVR above 80%.
There is also an important trade-off. Waiting until you have a 20% deposit may save you from paying LMI, but property prices could rise while you are saving. Sometimes paying LMI and entering the market earlier may produce a better overall result. I believe LMI should be treated as a buying cost to compare, not automatically as “wasted money”. The smarter question is whether buying now or waiting is likely to put you in the stronger position.
2. Can the Australian Government 5% Deposit Scheme help me avoid LMI?
Eligible buyers may be able to purchase a home with a deposit as small as 5% without paying LMI through the Australian Government 5% Deposit Scheme. Eligible single parents or legal guardians may be able to buy with a deposit as low as 2%. Housing Australia guarantees part of the loan, reducing the lender’s exposure.
Income caps were removed and property price caps increased when the expanded scheme began on 1 October 2025. Applicants must still satisfy the scheme requirements and the participating lender’s credit criteria. You can review the current rules through Moneysmart’s house deposit guide before comparing participating lenders and home loan rates.
3. Can a family guarantor home loan avoid Private Mortgage Insurance?
A family guarantor may use part of the equity in their property to support your mortgage. This can reduce the lender’s effective exposure to 80% or less and may allow you to avoid LMI without providing the full 20% deposit yourself.
Guarantor home loans are offered by lenders including Westpac and other Australian banks, subject to their individual policies. This is not a casual favour. A guarantor takes on a real financial and legal risk if the borrower cannot make the repayments. Both parties should obtain independent legal and financial advice before proceeding.
4. Do professional home loans offer an LMI waiver?
Some lenders provide LMI waivers or reduced-deposit home loans for eligible professionals. Doctors, dentists, pharmacists, lawyers, accountants, nurses and other healthcare professionals may qualify with selected banks. Eligibility can depend on the profession, professional registration, income, property, loan size and LVR.
ANZ, Westpac, NAB, Commonwealth Bank and specialist mortgage lenders may have different professional home loan policies. A profession accepted by one lender may not qualify with another, so comparing more than the advertised home loan interest rate is essential. These policies can change. Always confirm the current eligibility rules before relying on an LMI waiver.
5. Can I negotiate or compare lenders to avoid LMI?
Different mortgage lenders may assess the same borrower and property differently. Commonwealth Bank may apply LMI or its Low Deposit Premium to some low-deposit applications. ANZ, Westpac, NAB and non-bank lenders may use different insurers, valuation methods, lending limits and waiver policies.
A lender’s valuation can also affect your LVR. If you agree to pay $700,000 but the bank values the property at $680,000, it may calculate the LVR using the lower figure. That could increase the LMI cost or change your approval. Comparing lenders can uncover a better policy, but avoid making several home loan applications at once. Too many credit enquiries may affect your credit profile. Compare your likely options first, then apply with purpose.
6. Can a gifted deposit or extra savings help me avoid LMI?
A financial gift from a family member may help increase your deposit and reduce your LVR. However, lenders may ask where the money came from and whether it must be repaid. Some also require evidence of genuine savings, particularly for high-LVR house loans.
An extra few thousand dollars can sometimes move an application into a lower LVR tier. That may reduce the mortgage insurance premium, even if it does not remove LMI entirely. Before signing a property contract, ask how much additional deposit would be needed to reach the next pricing tier. The difference may be surprisingly small.
7. Can I avoid LMI when refinancing my mortgage?
You can generally avoid new LMI when refinancing if your mortgage is no more than 80% of the new lender’s property valuation. If you have less than 20% equity, the new lender may charge LMI even if you paid it when you first purchased the home. LMI is generally not transferred from one lender to another.
A higher property valuation or a lower loan balance could help bring your LVR below 80%. You might also reduce your loan before refinancing. Moneysmart warns that paying LMI again can outweigh the savings from switching to a lower home loan rate. That is why a refinance comparison should include fees, insurance costs, repayments and total interest—not just the headline rate.
Is Paying Private Mortgage Insurance Always a Bad Idea?
Not necessarily.
Avoiding a large extra cost sounds appealing, but waiting years to build a 20% deposit can have its own cost. House prices may rise, rent payments continue and the home you want may move further out of reach. Suppose LMI allows you to buy sooner and the property increases in value. In that case, paying the premium could turn out to be financially worthwhile. If buying stretches your budget or leaves you with no emergency savings, waiting may be safer. The answer should come from the numbers, not fear or frustration. Compare the cost of LMI with the likely cost of waiting, while allowing for interest, rent, purchasing expenses and your repayment comfort.
PMI vs LMI: What Is the Difference?
PMI is the common American term, while LMI is the standard Australian term. In the United States, borrower-paid PMI is often charged through monthly mortgage repayments and may be cancelled after sufficient equity is reached under applicable rules. Australian LMI is generally a one-off premium paid upfront or added to the home loan. It does not automatically disappear when the property reaches 20% equity because the premium has already been charged.
US strategies such as an 80/10/10 piggyback mortgage, VA loan or USDA loan do not directly apply to Australian borrowers. Australians should instead consider the Australian Government 5% Deposit Scheme, guarantor home loans, professional LMI waivers and lower-LVR mortgage options.
Frequently Asked Questions About Private Mortgage Insurance
What is Private Mortgage Insurance in simple terms?
Private Mortgage Insurance protects a mortgage lender if a borrower defaults. In Australia, it is usually called Lenders Mortgage Insurance. It protects the lender, not the homebuyer.
When do I have to pay LMI in Australia?
LMI is commonly required when you borrow more than 80% of the lender-assessed property value. The exact requirement depends on the home loan provider, borrower and property.
Can I avoid LMI with a 10% house deposit?
Possibly. You may qualify for a government-backed deposit scheme, family guarantor loan or professional LMI waiver. Otherwise, a 10% deposit will commonly result in an LVR above 80% and may attract LMI.
Is LMI added to monthly mortgage repayments?
LMI is generally a one-off cost in Australia. It may be paid at settlement or capitalised into the mortgage. If it is added to the home loan, your repayments and total interest may increase.
Can first home buyers avoid Lenders Mortgage Insurance?
Eligible first home buyers may avoid LMI through the Australian Government 5% Deposit Scheme. Other options may include a guarantor mortgage or occupation-based LMI waiver.
Do I get an LMI refund when I refinance?
You should not assume you will receive a refund. LMI is generally non-refundable and cannot be transferred to a new mortgage. Refund arrangements can vary, so check the terms of your existing loan and insurance premium.
Which lenders offer home loans without LMI?
ANZ, Commonwealth Bank, NAB, Westpac and other lenders may offer no-LMI options for eligible government scheme participants, guarantor borrowers or selected professionals. Policies, limits and eligibility requirements vary.
Compare Home Loans Before Paying More Than You Need To
Private Mortgage Insurance or LMI can add thousands of dollars to a home purchase, but it does not always have to stand between you and the front door. The right lender, deposit strategy or government-backed option could reduce the cost—or help you avoid LMI completely.
