Buying a first home in Australia often stalls at one hurdle: saving a big enough deposit to avoid LMI. The First Home Buyer Guarantee helps eligible buyers enter the market sooner by reducing, and often removing, LMI at lower deposit levels.
This guide explains how the scheme works, how it changes LMI outcomes, and what first home buyers should check before applying.
What is the First Home Buyer Guarantee and who is it for?
The First Home Buyer Guarantee is a federal program that lets eligible first home buyers purchase with a low deposit while the government guarantees part of the loan. It is designed for Australians with limited savings who can service a mortgage but cannot reach a 20% deposit.
In plain terms, it helps buyers get into a home sooner, and it often changes whether LMI applies at all.
How does Lenders Mortgage Insurance work in Australia?
Lenders Mortgage Insurance protects the lender, not the borrower, when the deposit is under 20% and the loan-to-value ratio (LVR) is high. Many Australian lenders charge LMI when a borrower has less than a 20% deposit, though pricing varies by lender and risk profile.
LMI can be paid upfront or capitalised into the loan, which increases repayments and interest over time.
Why do lenders charge LMI when the deposit is under 20%?
A smaller deposit increases the lender’s risk because there is less equity buffer if property prices fall or if the loan goes into default. LMI shifts some of that risk to an insurer, which is why lenders often require it for high-LVR loans.
For many first home buyers, LMI becomes a major cost right at the point they are already stretched.
How does the First Home Buyer Guarantee reduce LMI?
The First Home Buyer Guarantee reduces LMI by allowing eligible buyers to borrow with as little as a 5% deposit while avoiding LMI in many cases. It works because the government guarantee covers part of the lender’s risk, similar to how a larger deposit would.
When the scheme applies, the loan can be treated more like a lower-risk loan, so LMI may not be charged.
Does the First Home Buyer Guarantee remove LMI completely?
In many cases, yes. If they are approved under the scheme through a participating lender and meet the requirements, LMI is typically not payable even with a deposit below 20%.
That said, outcomes depend on lender policy, the specific loan structure, and whether the loan remains within the scheme rules through settlement.
What deposit is needed to avoid LMI under the scheme?
Eligible buyers can often avoid LMI with a 5% deposit under the First Home Buyer Guarantee, provided they meet serviceability and other conditions. Without the scheme, avoiding LMI usually requires a 20% deposit.
This is the core reason the First Home Buyer Guarantee reduces LMI for buyers who are otherwise ready to repay a mortgage.
How does the government guarantee change the lender’s risk?
The guarantee effectively reduces the lender’s exposure if the borrower defaults and the sale proceeds do not clear the debt. With the scheme, the lender may be comfortable offering a high-LVR loan without using LMI as the risk offset.
This is why the First Home Buyer Guarantee reduces LMI in practice, even though the borrower is still borrowing at a high LVR.
What are the main eligibility rules buyers should know?
Eligibility can change over time, but the scheme generally focuses on first home buyers who meet income caps and plan to live in the property as an owner-occupier. There are also property price caps that vary by state and region, including metro and non-metro areas.
Buyers also need to fit the definition of a first home buyer, which usually means they have not owned property in Australia before.
How do property price caps affect access to the scheme?
Price caps limit which properties can be purchased under the program, and they differ across Australia. A home that is suitable for a buyer’s budget might still fall outside the cap in some higher-priced suburbs, especially in Sydney and parts of Melbourne.
If a property is above the cap, the buyer cannot use the First Home Buyer Guarantee on that purchase, so LMI may return to the table.
Which lenders offer the First Home Buyer Guarantee?
The program is only available through participating lenders, which include a mix of major banks and smaller lenders, depending on the year’s panel. Buyers typically apply through a lender just like a standard home loan, then the lender assesses whether a guarantee place is available.
It matters because even if they are eligible, they cannot use the scheme with a non-participating lender.
How does the First Home Buyer Guarantee compare to paying LMI?
Paying LMI can sometimes be worth it if it helps them buy earlier and property prices rise, but it is still a real cost. Avoiding it can keep upfront funds lower and reduce the total loan cost if LMI would otherwise be capitalised.
For many borrowers, the simple benefit is cashflow: the First Home Buyer Guarantee reduces LMI and leaves more savings for moving costs, furnishings, and a buffer.
What costs remain even if LMI is avoided?
They still need to budget for loan fees, conveyancing, building and pest inspections where relevant, and lender valuation costs. They may also face lenders’ fees tied to the specific loan product they choose.
In some states and territories, stamp duty concessions for first home buyers may apply, but that is separate from the First Home Buyer Guarantee.
Can they use the First Home Buyer Guarantee with other first home incentives?
Often, yes, provided they meet each program’s rules. Some buyers combine the guarantee with state-based first home owner grants or stamp duty relief, depending on the property type and location.
They should confirm compatibility because each incentive has different thresholds, and the strictest rule usually becomes the limiting factor.
What types of properties can be bought under the scheme?
The scheme usually supports owner-occupied homes, which can include existing homes and, in some cases, new builds depending on the specific guarantee stream. Buyers must generally move in within a required timeframe and continue to occupy the home for a minimum period.
This owner-occupier focus is part of why the scheme is not aimed at investors.
What happens if they refinance later?
Refinancing may be possible, but the guarantee usually does not automatically transfer to a new lender. If they refinance while still above 80% LVR, the new lender might require LMI unless another exemption applies.
This is a key detail: the First Home Buyer Guarantee reduces LMI at purchase, but it does not always protect them from LMI later if they refinance early.
What if they want to buy with a deposit smaller than 5%?
A deposit under 5% is generally outside the standard First Home Buyer Guarantee settings. At that point, they may need to consider other options, such as saving longer, using an acceptable gift strategy where permitted, or reassessing the purchase price.
If they proceed without the scheme at a very high LVR, LMI can be substantial and approval may be harder.

How does the scheme affect interest rates and loan features?
Rates depend on the lender and product, not the guarantee itself. Some participating lenders may offer competitive owner-occupier rates, while others may have fewer features or tighter credit policy.
They should compare offset accounts, redraw, package fees, and repayment flexibility, because avoiding LMI is only one part of the total cost.
What should buyers prepare before applying?
They will need proof of income, savings history, liabilities, and identity documents, just like any Australian mortgage application. Lenders will also assess genuine savings requirements, living expenses, and whether the buyer can service repayments if rates rise.
Being pre-approved first can help them shop within the price cap and act quickly when they find a suitable property.
What are common misconceptions about avoiding LMI?
Some buyers assume any 5% deposit means no LMI, but that is only true when the loan is approved under the scheme or another exemption applies. Others think LMI protects them, when it actually protects the lender.
A clearer rule of thumb is this: without an exemption, high-LVR loans in Australia often attract LMI.
How can they decide whether the First Home Buyer Guarantee is the right fit?
It is usually a strong fit when they have stable income, limited deposit, and want to buy within the relevant price cap. If they are close to a 20% deposit, they may compare the benefit of waiting versus buying sooner, especially in fast-moving markets like Brisbane, Perth, and Adelaide.
For many first-time purchasers, the First Home Buyer Guarantee reduces LMI enough to make buying achievable without draining their emergency savings.
What is a simple takeaway for first home buyers?
The main point is straightforward: the First Home Buyer Guarantee reduces LMI by replacing what a larger deposit would normally do, which is reduce lender risk. For eligible Australians buying an owner-occupied home within the caps, that can remove one of the biggest upfront barriers to entry.
If they want certainty, they should speak with a participating lender or an Australian mortgage broker and confirm how the First Home Buyer Guarantee reduces LMI for their exact loan scenario.
