Most first home buyers spend months fixated on one number: 20%. That is the deposit threshold where lenders’ mortgage insurance disappears, and somewhere along the way, it became embedded in Australian property culture as the marker of a “proper” deposit. But for many buyers today — particularly in Sydney, Melbourne, Brisbane, and Perth, where property values have climbed faster than savings accounts — reaching that threshold takes years. In that time, rents keep rising, property prices keep moving, and the gap between where you are and where you need to be can actually widen rather than narrow.
The real question is not whether to avoid a lender’s mortgage insurance at all costs. Which strategy puts you into a home with the least overall downside, given your specific deposit, income, profession, family situation, and how long you realistically expect to hold the property?
This article cuts through the options and gives you a practical framework for making that call — not a list of products, but an honest comparison of strategies so you can understand what each one actually costs you, what it requires of you, and where the risks sit.
What “Low Deposit” and “No LMI” Actually Mean
These two phrases are often used interchangeably, but they describe different things.
A low deposit home loan simply means borrowing more than 80% of the property’s value — anything where your loan-to-value ratio (LVR) sits above 80%. Lenders generally permit this, but they require protection against the risk of you defaulting before they have recovered enough of the loan. That protection is lenders mortgage insurance, commonly called LMI. It is a one-off premium that protects the lender, not you, and it is typically added to your loan balance so you are effectively borrowing more to cover it.
A no-LMI pathway is any route that gets you into a property above 80% LVR without triggering that premium. These include government-backed guarantee schemes, family guarantor arrangements, profession-specific lender waivers, and certain lender pricing structures where the LMI cost is traded for a higher interest rate. “No LMI” does not automatically mean “no cost.” In several of these structures, you are still paying — just differently.
Understanding that distinction matters a lot before you decide which path to take.
The Five Ways Australian First Home Buyers Buy with Less Than 20%
Pay LMI and Buy Now
This is the most straightforward path and, despite its reputation, not always the worst one financially. If you buy with a deposit below 20%, the lender arranges LMI through a provider like Helia or QBE, and the premium is added to your loan. On a $700,000 purchase with a 10% deposit, LMI might cost roughly $12,000 to $18,000, depending on the lender and insurer, though exact figures vary. That amount capitalised into a loan at a standard variable rate does add to your interest over time — but if property values are rising in your market and you are renting while you save, the delay itself carries a cost that LMI sometimes does not.
First Home Guarantee and Government-Backed Schemes
Housing Australia administers several guarantee schemes that allow eligible buyers to purchase with a deposit as low as 5% without paying LMI. The government guarantees the difference between your deposit and 20% of the purchase price, removing the lender’s exposure and therefore the need for LMI. It is not a cash grant — the government does not hand you money. It is a guarantee document that satisfies the lender’s risk requirement.
The First Home Guarantee covers first home buyers purchasing as an individual or a couple. The Family Home Guarantee supports eligible single parents, including non-first-home buyers in some cases, with a 2% deposit. The Regional First Home Buyer Guarantee applies to properties in designated regional areas. All schemes operate through a list of participating lenders, which means not every lender or every loan product qualifies.
As of late 2025, Housing Australia expanded access to these schemes, including unlimited places for eligible first home buyers under the First Home Guarantee, and revised property price caps across most states and territories. Eligible property types include existing homes as well as new builds, house-and-land packages, land plus a separate building contract, and off-the-plan dwellings — a point that some articles in this space get wrong by implying only new properties qualify.
Guarantor Loan
A guarantor loan uses equity in a family member’s property — almost always a parent’s home — as additional security for your loan. This removes the LMI requirement even at very high LVRs, and in some structures allows you to borrow the full purchase price including purchase costs. The guarantee can be limited to a specific portion of the loan rather than the full amount, which reduces the family member’s exposure.
The benefit is real: you can buy sooner, avoid LMI, and potentially borrow enough to cover stamp duty. The trade-off is also real. If you default, the guarantor’s property is at risk. That is not a hypothetical — it is a legal obligation, and both the borrower and guarantor should obtain independent legal advice before signing. Most lenders will also assess the guarantor’s own financial position to ensure they could absorb the obligation.
Profession-Based LMI Waiver
A number of lenders offer LMI waivers to borrowers in specific professions, recognising that certain careers correlate with lower default risk and strong income stability. Eligible professions typically include medical practitioners (GPs, specialists, dentists, veterinarians), lawyers, accountants, and some senior finance professionals. The LVR threshold for a waiver varies by lender — some extend it to 90% LVR, others to 95% — and the loan size may also need to fall within certain limits.
If you work in one of these fields and are not aware that this option exists, it is worth asking your broker specifically, because not all lenders advertise these policies publicly, and the criteria differ between institutions.
Nurses and teachers are two groups that often don’t realise they may qualify for profession-specific lending benefits. If you’re a nurse, some lenders treat your profession as lower-risk, given stable public sector employment and consistent income, which can open doors to more favourable loan structures. The same applies to teachers, where long-term job security and salary progression are viewed positively at assessment. Borrowers in these roles are worth exploring home loan options tailored for nurses or home loans designed for teachers before assuming standard LMI terms are their only option. For those who do qualify for a full waiver — whether through profession, income, or loan structure — LMI-waived loans can remove a cost that, depending on the purchase price, might otherwise run into the tens of thousands.
Lender-Specific No-LMI Pricing Model
Some non-bank lenders offer loans above 80% LVR without charging LMI, but instead apply a higher interest rate. The logic from the lender’s side is that the rate premium compensates for the additional risk rather than a separate insurance product. From a borrower’s perspective, this can be either better or worse than paying LMI, depending entirely on how long you hold the loan before refinancing.
If you buy, benefit from property value growth, and refinance to a standard lender within two or three years once your LVR drops below 80%, the rate premium over that period may cost less than the LMI you would have paid upfront. If you stay on that product longer than expected, the reverse can be true. This model requires you to run the numbers on your specific situation rather than assume it is the cheaper option.
No LMI vs Low Deposit: A Practical Comparison
Here is how the main strategies stack up across the factors that matter most to a first-home buyer making this decision:
Upfront cash required: Government guarantee and LMI-paid paths both work with 5% to 10% deposits, though you still need money for stamp duty, legal fees, inspections, and other purchase costs. A guarantor loan can reduce the cash requirement most dramatically, sometimes to very little beyond a holding deposit. Profession waivers typically require 10% at a minimum. The lender-pricing model generally wants 10% to 15%.
Monthly repayments: Capitalising LMI into your loan increases your loan balance and therefore your repayments. A rate-premium model will push your repayment up through a higher rate rather than a larger principal. A guarantor loan at standard rates keeps your repayments as low as possible for the amount borrowed.
Total cost over five years: This is where the answer becomes highly individual. LMI paid upfront and capitalised into a loan at a standard rate may cost less over five years than a rate premium product held for the same period. Government guarantee schemes, where available, tend to offer the best cost position because there is no LMI and no rate penalty — provided you qualify and can find an eligible property under the price caps.
Approval difficulty: Standard LMI-paid loans are the most widely available option and subject to the fewest additional eligibility criteria. Government schemes have income, citizenship, property type, and price cap requirements. Guarantor loans require a willing family member with sufficient equity and a lender willing to structure it that way. Profession waivers require verified employment in a qualifying role.
Refinancing flexibility: Once your LVR drops below 80% through a combination of repayments and property value growth, most pathways allow refinancing to a competitive standard product. With a guarantor loan, the goal is typically to reach the point where the guarantor can be released from the security, which usually requires your LVR to fall below 80% of the secured property’s value without the guarantee.
Family risk: The only pathway that introduces family risk is a guarantor loan. All other options keep your financial obligations and your family’s financial obligations separate.
When Paying LMI Is the Smarter Move
Paying LMI gets an unfairly bad reputation. For some borrowers, it is genuinely the right call.
If you have a 5% to 10% deposit, steady income, and you are buying in a market where prices have been rising faster than your savings rate, buying sooner with LMI can leave you better off than waiting. The LMI cost is fixed at the point of purchase. Property value growth (in markets where that applies) is not capped. If a property you buy today for $750,000 is worth $820,000 in two years, the $15,000 LMI you paid looks different in that context than it did on the day you signed.
LMI also makes sense when you do not have access to a guarantor, do not qualify for a government scheme, and do not work in a profession that attracts a waiver. In that case, it may simply be your only viable path to buying without an indefinite savings timeline.
It is also worth noting that LMI can sometimes be partially refunded if you refinance or sell early, depending on the insurer and how much time has elapsed — though this is not guaranteed and the conditions vary.
When Avoiding LMI Is Clearly Better
There are situations where a no-LMI pathway is clearly worth pursuing.
If you qualify for the First Home Guarantee and can find a suitable property under the price cap for your state, this is generally the strongest starting point. You pay a 5% deposit, avoid LMI, and access standard market interest rates through a participating lender. The main constraints are eligibility and stock — finding a suitable property at a qualifying price in a competitive market is not always straightforward.
If you are a medical professional, lawyer, or accountant with at least 10% deposit and a strong income, a profession-based LMI waiver can save you a significant amount with no rate premium attached, depending on the lender. It is worth comparing two or three lenders to see what each offers.
If your parents have equity in their property and are willing to act as guarantor, and your relationship and financial position make that a viable conversation, a guarantor loan can eliminate LMI entirely and potentially help you buy with minimal cash. The structure can be unwound once you have enough equity, and a good broker can help you plan toward that milestone from the outset.
Real Borrower Scenarios
The 5% Saver with No Family Support
Maya is a 29-year-old teacher in Brisbane with $32,000 saved — roughly 5% of the property she wants to buy. She has no family who can act as guarantor and earns above the income threshold for the First Home Guarantee as a single applicant. Her most realistic path is a low-deposit loan with LMI, or waiting until she saves closer to 10% to reduce the LMI premium. A broker in this case would look at whether any participating lenders can make the First Home Guarantee work within her income, and if not, would model the cost of buying now versus delaying six to twelve months to reduce LMI exposure.
The 10% Saver Deciding Whether to Wait
James and Priya have $85,000 saved on a combined income of $160,000. They are close to 12% deposit on the home they want. LMI at this LVR would be lower than at 5% — around $6,000 to $9,000, depending on the lender — and they are considering waiting another six months to hit 15%. A broker would model whether the savings from reduced LMI (and potentially a better rate at lower LVR) outweigh the risk of the property increasing in value while they wait. In many markets, six months of price movement can outpace six months of additional savings.
The Professional Borrower
Dr. Chen is a GP in her early 30s, buying her first home in Melbourne. She has a 10% deposit and a high income. She qualifies for an LMI waiver through multiple lenders. Her broker compares three lenders offering the waiver to find the most competitive interest rate, because there is no standard rate attached to these products. The LMI saving is meaningful — potentially $20,000 or more at that purchase price — and she does not have to pay a rate premium to access it.
The Guarantor-Supported Buyer
Tom is 27 and has saved $25,000 — not enough for a deposit on his own. His parents own their home outright and are willing to provide a limited guarantee over a portion of his loan. The broker structures the loan so that the guarantee is limited to the amount needed to bring the LVR to 80%, rather than applying over the full loan balance. Tom buys without LMI. The goal is to grow his equity over three to five years so the guarantee can be released. The broker documents this timeline and the conditions for release from the outset.
The Single Parent
Sandra is a 38-year-old nurse with one child and $18,000 in savings. She does not meet the threshold for the First Home Guarantee as a first home buyer because she owned a property previously. However, she may qualify for the Family Home Guarantee with a 2% deposit, depending on her income and the property she is purchasing. A broker familiar with the current scheme settings would check her eligibility before she assumes she has no options — and might also look at whether a guarantor arrangement with a family member could complement or replace the scheme pathway.
The Hidden Costs That Catch First Home Buyers Off Guard
Every strategy in this article requires cash beyond your deposit, and this is where a lot of first home buyers get a shock at settlement.
Stamp duty is the biggest one. In most states, it is not included in your loan and cannot be capitalised — you pay it at or before settlement. Some states offer concessions or exemptions for first-home buyers below certain price thresholds, which can make a significant difference. A broker can help you understand what applies in your state, but you need to have that cash ready.
Legal and conveyancing fees typically run $1,500 to $3,000. Building and pest inspections cost $400 to $700, depending on the property. Lender application fees, valuation fees, and loan establishment fees vary by lender and product — a no-fee loan might not have these, but a packaged loan might. Mortgage registration fees are a government charge. And then there are moving costs, utility connections, and the practical costs of setting up a home.
A 5% deposit that just covers the purchase price is not enough to complete a purchase. For most buyers, having 5% deposit plus a further 3% to 5% in cash for costs is the minimum realistic starting point, and more is always better.
One of the most common misunderstandings is that government guarantee schemes or guarantor loans eliminate the need for cash entirely. They do not. They remove the LMI requirement, but you still need cash to complete the transaction.
Eligibility and Lender Rules That Matter
Each pathway has its own set of eligibility requirements, and many borrowers discover these constraints only after they have started the process.
For government guarantee schemes, you need to meet income caps (currently $125,000 for individuals and $200,000 for couples or co-buyers), be a first home buyer in most cases, intend to occupy the property as your principal place of residence, meet citizenship requirements, and purchase within the price caps for your state or territory. Participating lenders also apply their own serviceability and credit criteria on top of the scheme requirements.
For guarantor loans, the guarantor needs sufficient equity in their property, typically a good credit history, and the lender needs to assess that the guarantor could manage the obligation if called upon. Most lenders will not allow a guarantor arrangement if the guarantor themselves has an existing mortgage at high LVR.
For LMI-paid loans, lenders assess genuine savings, which generally means funds held in your account for at least three months. Gifts from parents, FHSS withdrawals, and government grants may or may not satisfy the genuine savings test depending on the lender. This is a specific area where broker advice matters, because lender policies on genuine savings differ significantly.
Your credit file matters across all pathways. Missed payments, defaults, and enquiries affect your assessment. Lenders assess your debt-to-income ratio, your living expenses, existing debts including HECS-HELP, credit cards, and car loans, and your employment stability. Casual and contract employees face additional scrutiny at higher LVRs, though many lenders have workable policies for these borrower types when structured correctly.
Mistakes Worth Avoiding
Assuming “no LMI” means no cost. In some structures, such as lender-specific rate-premium models, you pay for the absence of LMI through a higher rate over the life of the loan. Whether that is more or less than the LMI would have cost depends on how long you stay in that product.
Forgetting stamp duty. It is remarkable how often this happens. A 5% deposit with no buffer for stamp duty is not a 5% deposit — it is a deposit that will leave you short at settlement.
Assuming a government guarantee means government money. It is a guarantee document, not a grant. The government is not putting money toward your purchase. You are still borrowing the full amount from a lender.
Conflating the First Home Super Saver Scheme with a deposit pathway. The FHSS scheme allows you to withdraw voluntary superannuation contributions for a first home deposit, which is a tax-effective way to accelerate savings. But it is a savings mechanism, not a lender product. The funds may or may not satisfy the genuine savings test at every lender.
Involving a guarantor without proper legal advice. Both the borrower and the guarantor should obtain independent legal advice before entering a guarantor arrangement. It is not a formality — it is important that the guarantor fully understands what they are committing to.
Borrowing to your maximum. Lenders will approve you for more than you should borrow in some cases. Just because a lender will extend 95% LVR does not mean your cash flow can comfortably absorb that loan. Factor in rate rises, maintenance costs, and life events before taking the absolute maximum a lender will offer.
A Decision Framework: Which Option Fits You?
Rather than prescribe a single answer, here is a practical way to work through the decision.
Start with eligibility. Can you access the First Home Guarantee? If yes, and you can find a suitable property under the price cap, this is typically the strongest starting point because it removes LMI with no rate penalty. If not, move to the next question.
Do you work in a qualifying profession? If yes, speak to a broker who can identify which lenders offer a waiver and at what LVR. This may be better than LMI-paid even if the scheme is not available to you.
Do you have family support available? If a parent or close family member has equity and is willing to assist, a guarantor structure can eliminate LMI entirely and potentially reduce the cash you need upfront. This needs careful legal and financial consideration, not just a casual agreement.
If none of the above applies, you are likely choosing between paying LMI now and buying, or waiting to accumulate a larger deposit. At that point, the question becomes whether the cost of LMI is less than the cost of delay in your market. That is a modelling exercise a broker can help you run with real numbers.
The lender-pricing no-LMI model is worth considering if you have a clear plan to refinance within two to three years and the rate premium over that period is less than the LMI cost. Run the maths before committing.
Frequently Asked Questions
Is it better to pay LMI and buy sooner, or wait and save a bigger deposit?
It depends on your market and your savings trajectory. In a market where property values are increasing, the cost of delay can exceed the cost of LMI. In a flat or declining market, waiting to reduce LMI makes more sense. A broker can model both scenarios with current data for your target area.
Is “no LMI” actually cheaper than a low-deposit loan with LMI?
Not always. Government guarantee schemes offer no-LMI access without a rate penalty, which is usually the cheapest path where available. But some no-LMI structures — particularly rate-premium products — shift the cost into your interest rate. Whether that ends up cheaper depends on how long you hold the loan before refinancing.
Can I buy my first home with 5% deposit and no LMI in Australia?
Yes, through the First Home Guarantee if you are eligible. You need to meet the income caps, citizenship requirements, and find a property within your state’s price threshold. The scheme is administered through participating lenders only, so not every bank offers it.
What is the difference between the First Home Guarantee and a guarantor loan?
The First Home Guarantee is a government-backed scheme where Housing Australia guarantees part of your loan to the lender. A guarantor loan uses a family member’s property as additional security. Both can remove LMI, but they involve completely different eligibility criteria, risk profiles, and structures. One relies on a government policy; the other relies on a family member’s property.
Does a guarantor loan mean my parents are on the mortgage?
No. A guarantor is not a co-borrower. Your parents do not appear on the loan as borrowers, but their property is used as security for part of your loan. If you default, the lender can make a claim against that security. They are not legally responsible for your repayments day to day, but they are exposed if things go wrong.
Can I use the First Home Super Saver Scheme and the First Home Guarantee together?
In most cases, yes. The FHSS scheme helps you accumulate savings within superannuation, which can be withdrawn as a deposit contribution. The First Home Guarantee is a separate lender scheme that removes the LMI requirement. They operate independently and can be used at the same time, though you need to check that your FHSS withdrawal satisfies the genuine savings requirements of your chosen lender.
How much cash do I actually need beyond the deposit?
For most purchases, you should budget at least 3% to 5% of the purchase price on top of your deposit to cover stamp duty (where applicable), legal fees, inspections, and other purchase costs. Stamp duty varies significantly by state and property price, and first home buyer concessions or exemptions may reduce or eliminate it depending on where you are buying.
Will paying LMI reduce my borrowing capacity?
If LMI is added to your loan balance, your total loan amount increases, which means higher repayments. Lenders assess your ability to service the total loan, including any capitalised LMI. In some cases this can reduce the purchase price you qualify for, though the effect depends on your income and the lender’s assessment criteria.
Which professions can get an LMI waiver?
Eligibility varies by lender, but typical qualifying professions include medical doctors, dentists, specialists, veterinarians, lawyers, barristers, solicitors, accountants, and some finance executives. Some lenders extend waivers to other allied health professionals and engineers. The LVR limit and loan size cap for the waiver also differ between lenders, so it is worth comparing options.
Can I refinance later to remove a guarantor or access a better rate?
Yes, and this is often the plan from the start with guarantor loans. Once your LVR falls below 80% — through a combination of repayments and property value growth — you can typically apply to release the guarantor from the security. Refinancing to a different lender at that point may also give you access to a more competitive rate. A broker can help you build a timeline toward that goal.
What happens if property values fall after I buy with a small deposit?
If your property value falls below your loan balance, you are in negative equity. This does not affect your loan repayments directly, but it does mean you cannot refinance to a different lender or sell without a potential shortfall. This risk is higher at 90% to 95% LVR and is why buying in a stable area with sound fundamentals matters, not just whether LMI is payable.
Conclusion
The question of whether to pay LMI or pursue a no-LMI pathway does not have a universal answer. What it has is a framework — and the right answer depends on your deposit size, income, profession, access to family support, target market, and how long you plan to hold the property before refinancing or selling.
Government guarantee schemes offer the cleanest no-LMI option where available, and are worth pursuing first if you qualify. Profession-based waivers are genuinely underused by eligible borrowers who simply do not know they exist. Guarantor loans are powerful but require careful structuring and honest family conversations. And paying LMI — the option that carries the most social stigma — is sometimes the most rational choice when the cost of waiting outweighs the cost of the premium.
Before you decide, sit down with a broker who will model the actual numbers for your situation rather than defaulting to generic advice. The difference between strategies can be tens of thousands of dollars over five years, and the right path for you is not the same as the right path for the borrower next door.
