A home loan deposit is the upfront amount you contribute toward a property purchase, and it directly determines how much you borrow, what rate you pay, and whether you need Lenders Mortgage Insurance (LMI). Home loan deposit options in Australia range from as low as 2% under the Queensland Housing Finance Loan to the standard 20% that lenders prefer. Knowing which pathway suits your situation can save you tens of thousands of dollars and get you into your first home sooner than you think.
1. What are the main home loan deposit options available?
The deposit you bring to a home loan sets the terms of almost everything that follows. Lenders measure your deposit as a percentage of the property's value, which produces your loan-to-value ratio (LVR). A lower LVR signals less risk to the lender, which typically means better rates and fewer conditions attached to your loan.
Here is a quick comparison of the most common deposit pathways available to first-time buyers in Australia:
| Deposit size | LVR | LMI required? | Government scheme available? |
|---|---|---|---|
| 20% or more | 80% or below | No | Not needed |
| 10% | 90% | Usually yes | Possible |
| 5% | 95% | Yes, unless scheme applies | First Home Guarantee |
| 2% | 98% | Scheme-dependent | Queensland Housing Finance Loan |
Each option carries a different cost profile and eligibility requirement. The right choice depends on your savings, income, and how quickly you want to buy.
2. The standard 20% deposit and why lenders love it
A 20% deposit equals an 80% LVR, which sits in the preferred lending band for most Australian banks and credit unions. At this level, lenders consider the loan lower risk, so they typically offer sharper interest rates and more flexible loan features. You also avoid LMI entirely, which is a meaningful saving on a $500,000 purchase.
The downside is time. Saving $100,000 on a $500,000 property while paying rent is a long road for most first-time buyers. That reality is exactly why the alternatives below exist. Still, if you are close to the 20% mark, it is worth pausing to consider whether a few more months of saving could eliminate thousands in insurance costs.
Pro Tip: Your deposit size shapes the rate you are offered. Even moving from 5% to 10% can shift you into a better rate tier with some lenders.
3. Low deposit loans: the 5% and 10% pathways
Low deposit loans let you buy with as little as 5% or 10% saved, but most lenders attach LMI to any loan above 80% LVR. LMI protects the lender, not you, if you default on the loan. That distinction matters because you pay the premium but receive none of the protection.
On a $500,000 purchase with a 5% deposit, LMI can add $16,832 to your loan balance. That amount is typically capitalised into the loan, meaning you pay interest on it for the life of the mortgage. The total cost over 30 years is considerably higher than the headline figure suggests.
Low deposit loans are still a legitimate path into the market, particularly when property prices are rising faster than you can save. First-time buyers with low deposits have historically built equity quickly in growth markets, which can offset the initial LMI cost within a few years.
4. Government schemes that reduce your deposit burden
The Australian Government's First Home Guarantee (formerly the First Home Loan Deposit Scheme) allows eligible buyers to purchase with a 5% deposit without paying LMI. The government guarantees up to 15% of the loan value, so the lender treats it as an 80% LVR loan. This is one of the most practical forms of home loan deposit assistance available to first-time buyers today.
Eligibility criteria apply. You must be an Australian citizen or permanent resident, meet income thresholds, and intend to live in the property. Places are limited each financial year, so timing your application matters. More lenders have been signing up to the scheme over recent years, which gives buyers more choice in who they borrow from.
The First Home Owner Grant (FHOG) is a separate state-based payment that can supplement your deposit. In Queensland, for example, eligible buyers receive $30,000 toward a new home. This does not replace your deposit but can reduce the gap between what you have saved and what you need.
Pro Tip: Government scheme places are allocated on a first-come, first-served basis each financial year. If you are close to eligible, speak to a broker before 30 June to avoid missing out.
5. The Queensland Housing Finance Loan: a 2% deposit option
The Queensland Housing Finance Loan is one of the lowest deposit home loan products available anywhere in Australia. It allows eligible buyers to purchase with as little as 2% deposit, with repayments capped at 35% of gross household income. The application fee in 2026 is $817.56.
This loan is administered by the Queensland Government and targets low-to-moderate income earners who cannot access standard bank finance. Eligibility is strict. You must be a Queensland resident, meet income and asset limits, and be unable to obtain a loan from a mainstream lender. The property must also fall within set price caps.
For buyers who qualify, this is an extraordinary option. A 2% deposit on a $400,000 property is just $8,000. That is achievable for many renters who have been unable to save a standard deposit while covering living costs. The Help to Buy Scheme, set to expand in 2024 and beyond, offers another shared equity pathway worth watching.
6. Using a guarantor to meet deposit requirements
A guarantor arrangement lets a family member, usually a parent, use the equity in their own property as additional security for your loan. This can bring your effective deposit up to 20% without you needing to save that amount yourself, which means you avoid LMI entirely.
The benefit is clear: you buy sooner and pay less upfront. The risk, however, sits with your guarantor. If you cannot meet repayments, the lender can pursue your guarantor's property to recover the debt. Guarantors carry real legal risk and should obtain independent legal and financial advice before agreeing to this arrangement.
"Guarantors must fully understand their potential legal and financial exposure before committing. This is not a favour to be taken lightly." — Canstar financial advisory insights
Lenders also scrutinise the source of your deposit funds carefully. Bank statements confirming genuine savings of at least 5% are typically required, even when a guarantor is involved. A gift from a family member may be accepted by some lenders, but it is treated differently from savings you have accumulated yourself.
7. Alternative deposit sources: gifts, personal loans, and second mortgages
Some buyers look beyond savings to fund their deposit. A cash gift from a parent or relative is the most common alternative, and many lenders accept it provided you can document the source and confirm it does not need to be repaid. A genuine gift is treated more favourably than a loan because it does not add to your debt obligations.
Personal loans used as a deposit are viewed negatively by most lenders. The borrowed amount increases your total debt, reduces your borrowing capacity, and signals to the lender that you have not demonstrated the savings discipline they want to see. Second mortgages carry similar concerns and are rarely a practical path for first-time buyers.
Some lenders offer LMI waivers for certain professions, including medical professionals, lawyers, and accountants. If you work in one of these fields, you may be able to borrow up to 90% LVR without paying LMI at all. This is a significant advantage that many eligible buyers are simply unaware of.
8. How deposit size affects your total loan cost
The size of your deposit does not just affect your LMI obligation. It shapes your interest rate, your monthly repayment, and the total amount you repay over the life of the loan. LMI enables earlier home ownership for many Australians, but it comes at a real cost that compounds over time.
Consider a $600,000 property. A 20% deposit of $120,000 means you borrow $480,000 with no LMI. A 5% deposit of $30,000 means you borrow $570,000 plus LMI, potentially adding over $20,000 to your loan balance. Over 30 years at a standard variable rate, the difference in total repayments is substantial.
A higher deposit also gives you a buffer against falling property values. If the market drops shortly after you buy, a 20% deposit means you are less likely to find yourself in negative equity, where you owe more than the property is worth. That buffer matters most in the early years of a loan.
9. How to choose the right deposit option for your situation
Choosing between deposit options comes down to three things: what you have saved, what you are eligible for, and how long you are willing to wait. There is no single right answer, but there is usually a best answer for your specific circumstances.
Work through these questions before you decide:
- How much have you genuinely saved? Lenders want to see at least 5% in genuine savings, separate from any gift or grant.
- Do you meet the income thresholds for government schemes? The First Home Guarantee and Queensland Housing Finance Loan both have income caps.
- Can a family member act as guarantor? If yes, have they received independent legal advice?
- Are you in an eligible profession for an LMI waiver? Medical, legal, and accounting professionals should check this first.
- Is the market moving faster than you can save? If so, a low deposit option now may cost less than waiting another two years.
A mortgage broker can run the numbers across all of these scenarios for you in a single conversation. That comparison is genuinely difficult to do on your own, particularly when lender policies change frequently.
Key takeaways
The best deposit option for your first home depends on your savings, income, profession, and eligibility for government schemes, not on a single universal rule.
| Point | Details |
|---|---|
| Standard 20% deposit | Avoids LMI and secures better rates, but requires significant upfront savings. |
| Government schemes | The First Home Guarantee allows a 5% deposit without LMI for eligible buyers. |
| Queensland 2% option | The Queensland Housing Finance Loan is the lowest deposit pathway in Australia for eligible low-income buyers. |
| Guarantor arrangements | A guarantor can eliminate LMI but carries serious legal risk that requires independent advice. |
| LMI as a trade-off | LMI adds thousands to your loan but can allow you to buy years earlier in a rising market. |
What I have learned from working with first-time buyers on deposits
After years of working with first-time buyers across Queensland and beyond, the thing that surprises people most is how many options actually exist. Most buyers walk in thinking they need 20% or they cannot buy. That belief keeps a lot of people renting for years longer than necessary.
The government schemes are genuinely useful, but they are not magic. The First Home Guarantee works well for buyers who are financially stable and ready to commit. The Queensland Housing Finance Loan is a lifeline for buyers who cannot access mainstream finance, but the eligibility criteria are tight and the application process takes time. I have seen buyers miss out because they did not apply early enough in the financial year.
What I caution people about most is the guarantor path. It works, and I have seen it help many families get into their first home. But I have also seen it create serious strain when repayments become difficult. Your parents putting their home on the line for your mortgage is a significant act of trust. Treat it that way. Get the legal advice. Have the honest conversation about what happens if things go wrong.
The buyers who make the best decisions are the ones who compare all their options side by side before committing. That means understanding the true cost of LMI, checking scheme eligibility early, and knowing what a lender actually sees when they assess your deposit. A good broker does not just find you a loan. They show you the full picture so you can choose with confidence.

FAQ
What is the minimum deposit for a home loan in Australia?
The minimum deposit for a home loan is typically 5%, though the Queensland Housing Finance Loan allows as little as 2% for eligible buyers. Most standard lenders require at least 5% in genuine savings plus costs.
Can I use a gift as my home loan deposit?
Many lenders accept a cash gift from a family member as part of your deposit, provided it is genuinely non-repayable and properly documented. Some lenders still require you to hold a portion in genuine savings alongside the gift.
What is LMI and do I always have to pay it?
LMI is Lenders Mortgage Insurance, a premium charged when your deposit is below 20% of the property value. You can avoid it through the First Home Guarantee, a guarantor arrangement, or an LMI waiver available to certain professions such as doctors and lawyers.
How does the First Home Guarantee work?
The Australian Government's First Home Guarantee allows eligible buyers to purchase with a 5% deposit without paying LMI, because the government guarantees the remaining 15% to the lender. Places are limited each financial year, so early application is recommended.
Does deposit size affect my interest rate?
A larger deposit generally results in a lower LVR, which lenders reward with sharper interest rates and more favourable loan conditions. Even increasing your deposit from 5% to 10% can move you into a better rate tier with some lenders.
