Saving a 20% deposit can be one of the biggest barriers to buying property in Australia.
For many buyers, especially first home buyers, waiting until they have a full 20% deposit may mean spending years on the sidelines while property prices, rent and borrowing conditions continue to change.
This is where lenders mortgage insurance, commonly called LMI, becomes part of the conversation.
LMI can allow some borrowers to buy with a smaller deposit. But it is also one of the most misunderstood costs in home lending.
The key point is this: LMI protects the lender, not the borrower.
That does not mean LMI is always bad. In some cases, paying LMI may help a buyer enter the market sooner. In other cases, it may be better to keep saving, reduce debts, use a guarantor structure, or consider whether a government scheme is available.
The right answer depends on your deposit, borrowing capacity, property price, lender options and long-term plans.
What Is Lenders Mortgage Insurance?
Lenders mortgage insurance is an insurance policy that protects the lender if a borrower defaults on their home loan and the lender suffers a loss after selling the property.
It does not protect the borrower.
If the lender makes a claim under the LMI policy, the insurer may pay the lender for the shortfall. However, the borrower may still remain liable for the loss, plus any costs, fees and charges.
This is why LMI should not be confused with mortgage protection insurance, life insurance, income protection or any type of cover that protects the borrower personally.
LMI exists because low-deposit loans are considered higher risk for lenders. The smaller the borrower’s deposit, the less equity buffer there is if the property value falls or the loan falls into arrears.
When Is LMI Required?
LMI is generally required when a borrower has less than a 20% deposit.
In lending terms, this usually means the loan-to-value ratio, or LVR, is above 80%.
For example:
| Purchase price | 20% deposit | 80% loan |
|---|---|---|
| $800,000 | $160,000 | $640,000 |
If the borrower needs to borrow more than $640,000 on an $800,000 purchase, the LVR is above 80% and LMI may apply.
However, LMI rules vary by lender, borrower type, property type and loan purpose.
Some lenders may offer limited promotions allowing certain borrowers to borrow above 80% without LMI. Some lenders may also waive LMI for selected professionals, such as eligible doctors, dentists, accountants, lawyers or other high-income professional categories, depending on their policy.
First home buyers may also be able to avoid LMI through an eligible government guarantee scheme.
LMI and the Australian Government 5% Deposit Scheme
Eligible first home buyers may be able to buy with a lower deposit under the Australian Government 5% Deposit Scheme.
From 1 October 2025, the expanded scheme allows eligible first home buyers to purchase with no LMI, no income caps and no waitlists, subject to scheme rules, property price caps and lender approval.
This can be significant because it may reduce the upfront cost of buying and allow eligible buyers to enter the market sooner.
However, the scheme does not mean everyone is automatically approved. Buyers still need to meet lender credit policy, borrowing capacity, savings and property requirements.
For NSW first home buyers, transfer duty support may also be relevant. Revenue NSW confirms eligible first home buyers may receive a full exemption or reduced rate of transfer duty under the First Home Buyers Assistance Scheme.
How Much Does LMI Cost?
The cost of LMI varies.
It is usually calculated based on factors such as:
- the loan amount
- the loan-to-value ratio
- the property value
- whether the loan is owner-occupied or investment
- whether the borrower is employed or self-employed
- the lender and mortgage insurer
- the borrower’s overall application strength
As a general rule, the higher the LVR and the larger the loan, the higher the LMI premium is likely to be.
LMI can cost thousands of dollars and, in some cases, tens of thousands of dollars.
It may be paid upfront or added to the loan, depending on lender policy. When LMI is added to the loan, this is called capitalising the LMI premium.
Capitalising LMI can reduce the cash needed at settlement, but it also means you are borrowing more and paying interest on that amount over time.
How LMI Affects Borrowers
LMI can affect borrowers in several important ways.
1. It Can Help You Buy Sooner
The main benefit of LMI is that it may allow you to buy with a smaller deposit.
For example, instead of waiting until you have a 20% deposit, you may be able to purchase with 10%, 8% or even 5% deposit, depending on lender policy and your circumstances.
This can be valuable in a rising market where the cost of waiting may be significant.
2. It Increases the Cost of Buying
LMI is an additional cost.
Even when added to the loan, it still increases the total amount borrowed. This can affect repayments, interest cost and your overall loan position.
The question is not simply, “Can I avoid LMI?”
The better question is, “Does paying LMI make strategic sense in my situation?”
3. It May Affect Loan Structure and Lender Choice
Not all lenders treat LMI the same way.
Different lenders use different mortgage insurers, pricing models, LVR limits and approval rules. Some may be more flexible for certain borrowers, property types or professions.
A broker can compare lenders and help identify whether there are better options available.
4. It Can Influence Future Refinancing
If your property value increases or you pay down the loan, your LVR may fall below 80%.
Once the LVR is below 80%, you may be able to refinance without paying new LMI, subject to lender approval and valuation.
However, if you refinance while your LVR is still above 80%, LMI may be payable again with the new lender.
In limited circumstances, a partial LMI refund may be available if a loan is repaid or refinanced early, but this depends on the lender, insurer, policy wording and timing. It should not be assumed.
Is Paying LMI Worth It?
Sometimes, yes.
LMI can be worth considering if it helps you buy a suitable property sooner, avoid years of extra rent, or enter the market before prices move further away.
But LMI is not automatically a good idea.
It may be better to keep saving or change strategy if:
- repayments would be too tight
- your job or income is uncertain
- you have unstable spending patterns
- you are relying on every dollar to settle
- the property is likely to be hard to value or refinance
- you could qualify for a no-LMI scheme soon
- reducing debts would improve your approval position
The decision should be based on numbers, not emotion.
How Can LMI Be Avoided?
There are several ways LMI may be avoided, depending on your circumstances.
Save a 20% Deposit
The most straightforward way is to contribute a deposit of at least 20%, plus purchase costs.
This usually keeps the LVR at or below 80%.
Use a Government Guarantee Scheme
Eligible first home buyers may be able to buy with a lower deposit and no LMI through the Australian Government 5% Deposit Scheme, subject to rules and lender approval.
Use a Family Guarantee
Some buyers may avoid LMI by using a family guarantee structure, where a family member provides additional security using equity in their property.
This can reduce the effective LVR for the lender, but it creates risk for the guarantor and should be considered carefully.
Use Additional Property Security
If you already own another property, additional security may help reduce LVR and avoid LMI.
However, using multiple properties as security can reduce flexibility, so the structure needs to be planned properly.
Use an LMI Waiver Policy
Some lenders offer LMI waivers for certain professionals, depending on income, occupation, membership or qualification requirements.
These policies vary significantly between lenders and can change over time.
LMI Is Not the Only Cost to Consider
A common mistake is focusing only on LMI.
When buying property, you also need to consider:
- deposit
- transfer duty or stamp duty
- conveyancing and legal costs
- building and pest inspections
- lender fees
- government registration fees
- moving costs
- insurance
- rates, strata or body corporate fees
- post-settlement cash buffer
A buyer with a lower deposit and no buffer may be exposed, even if the loan is technically approved.
The goal is not just to get into the property. It is to buy with a structure you can sustain.
How Evolve Lending & Finance Can Help
At Evolve Lending & Finance, we help buyers understand whether LMI should be avoided, accepted, or worked around with a better strategy.
We can help you:
- calculate your likely LVR
- estimate whether LMI may apply
- compare lenders and LMI policies
- assess government scheme eligibility
- review family guarantee options
