Most Australian lenders require a minimum deposit before approving a home loan, and the amount you need depends on the lender, the loan type, and whether you qualify for government assistance schemes. Speaking with a licensed mortgage broker can help you understand your specific borrowing position and identify options suited to your circumstances.
What "deposit" actually means in 2026
When lenders and brokers talk about a deposit, they mean the portion of the purchase price you contribute yourself, separate from borrowed funds. The deposit is expressed as a percentage of the property's value, and the remainder you borrow is called the loan-to-value ratio (LVR).
A higher deposit generally means a lower LVR, which reduces the lender's risk. That risk assessment shapes your interest rate, your loan approval chances, and whether you must pay Lenders Mortgage Insurance (LMI). Understanding these relationships is the foundation of any serious home-buying plan.
Your deposit is not the only upfront cost. Stamp duty, conveyancing fees, building and pest inspections, and moving costs all come out of your savings separately. A mortgage broker can walk you through a realistic "total upfront cost" estimate so you are not caught short at settlement.

The standard deposit benchmarks lenders use
Australian lenders have traditionally used specific LVR thresholds to categorise borrower risk. While exact requirements vary between institutions and are subject to change, a few general principles remain consistent.
Most mainstream lenders consider a loan with an LVR above a certain threshold to carry elevated risk and require the borrower to pay LMI or meet additional conditions. LMI is insurance that protects the lender, not you, yet the premium is typically added to your loan balance or paid upfront. The Australian Securities and Investments Commission's MoneySmart resource explains how LMI works and when it typically applies.
If you can contribute a larger deposit, you may gain access to more competitive loan products and potentially negotiate better terms. Conversely, borrowers with smaller deposits may still proceed, but the overall cost of the loan across its lifetime tends to be higher.

Government schemes that can reduce the deposit you need
For eligible buyers, federal and state government schemes can allow a purchase with a substantially smaller deposit, sometimes without triggering LMI requirements.
The Australian Government's Housing Australia administers several programmes, including the First Home Guarantee, the Regional First Home Buyer Guarantee, and the Family Home Guarantee. Each scheme has eligibility criteria related to income, property price caps, and buyer status. Places are limited and allocated in annual rounds, so eligibility in one financial year does not guarantee availability the next.
State and territory governments also operate their own first home buyer grants and concessions, particularly on stamp duty. Because these vary significantly by jurisdiction, the most reliable approach is to check your relevant state revenue office website or ask a broker who operates in your state.
It is important to understand that these schemes can assist with the deposit size required, but they do not reduce the amount you need to repay over the life of the loan. Qualifying for a scheme does not mean a loan is affordable for your circumstances, and a licensed credit adviser can help you assess that distinction honestly.

How lenders assess whether your deposit is "genuine savings"
Many lenders, particularly for higher-LVR applications, want to see that your deposit has been accumulated over time rather than gifted or rapidly moved into your account immediately before application. This is often called a "genuine savings" requirement.
Genuine savings typically refers to funds held in your name for a sustained period, evidenced through bank statements. The Reserve Bank of Australia publishes regular reports on housing lending standards that contextualise how Australian institutions approach credit risk, which is useful background reading.
Gifts from parents or family members are increasingly common in Australian property markets, and many lenders do accept gifted funds, often with additional documentation. Some lenders require a portion of the deposit to be genuine savings even if a gift is also involved. A broker can match you with lenders whose policies align with how your deposit has been accumulated.
If you are using equity in an existing property as your deposit for a second purchase, the assessment process differs again. A broker experienced in investment lending or upgrader scenarios is worth consulting early.

The role of a mortgage broker in navigating deposit options
A mortgage broker does not lend you money. Instead, they access a panel of lenders and help you identify products that suit your deposit size, financial history, and borrowing goals. Under the National Consumer Credit Protection Act 2009, brokers are legally required to act in your best interests and must hold an Australian Credit Licence or be a credit representative of a licence holder. You can verify a broker's credentials using the ASIC Credit Licence Register.
The best brokers will be candid with you about what deposit size genuinely strengthens your application versus what is the minimum floor to proceed. They can also explain how your deposit interacts with serviceability assessments, which relate to whether your income is sufficient to meet repayments under the lender's stress-test rate.

Deposit strategies worth discussing with a broker
There is no single correct deposit strategy. Your timeline, income stability, rental situation, and risk tolerance all shape what makes sense. That said, a few approaches come up often in conversations between brokers and buyers.
Continuing to save can increase your deposit percentage, potentially crossing thresholds that unlock lower LMI costs or better loan terms. Alternatively, entering the market sooner with a smaller deposit, particularly if assisted by a government scheme, may suit buyers in markets where property values are rising.
Some buyers use a guarantor arrangement, where a family member's property equity partially secures the loan, reducing or eliminating the LMI requirement. The APRA banking statistics pages offer context on how Australian lending volumes and risk categories shift over time, which can inform how cautious lenders are currently being.
Reviewing your cost guide on mortgage broker fees is also worthwhile before you engage one, so you understand when brokers are paid by lenders versus charging you directly.

FAQ
Q: Is there a universal minimum deposit for all Australian home loans? A: No. Requirements vary by lender, loan type, and borrower profile. Government schemes may allow purchases with a smaller deposit for eligible buyers. A mortgage broker can outline what threshold applies to your specific situation. Q: Does paying LMI mean I have a bad application? A: Not necessarily. LMI is a normal part of the home-buying process for many Australians, particularly first home buyers. It represents an additional cost, but it does not signal that your application is weak. ASIC MoneySmart has a plain-English explanation of how LMI premiums are calculated. Q: Can I use a personal loan to top up my deposit? A: Some lenders prohibit borrowed funds from forming part of your deposit, or will factor the personal loan repayments into your serviceability calculation, which reduces your borrowing capacity. You should disclose all liabilities to your broker and lender honestly, as required under the National Consumer Credit Protection Act 2009. Q: How does a guarantor arrangement affect the deposit I need? A: A guarantor, usually a close family member, offers equity in their own property as additional security. This can allow you to borrow a higher proportion of the purchase price without paying LMI. However, the guarantor takes on real financial risk. Independent legal and financial advice for the guarantor is strongly recommended before proceeding.---
