The deposit is often the number that makes buying a first home feel either possible or painfully far away. But a first home buyer deposit explained properly is more than a savings target. It is about understanding how your deposit affects your borrowing options, upfront costs, repayments and the level of financial breathing room you keep after settlement.
For many Australians, the goal is not necessarily to save a perfect 20 per cent before starting the conversation. The better goal is to build a deposit and buying plan that works for your income, the property you want and the life you want to live once you have the keys.
First home buyer deposit explained: what it actually is
Your deposit is the amount of the purchase price you contribute from your own funds. The remainder is generally covered by your home loan. If you buy a $600,000 property with a $120,000 deposit, you are borrowing $480,000, which is an 80 per cent loan-to-value ratio, or LVR.
The deposit is usually paid in two stages. After your offer is accepted, you may pay an initial deposit when contracts are exchanged. This is commonly 5 or 10 per cent, although the amount is negotiable and depends on the contract. The rest of your contribution is provided at settlement, alongside loan funds from your lender.
Importantly, your deposit is not the full amount of cash you need. You will also need to allow for buying costs such as stamp duty, conveyancing, building and pest inspections, lender fees, government registration charges and moving expenses. The right buffer can stop an exciting purchase becoming financially tight from day one.
How much deposit do first home buyers need?
A 20 per cent deposit is often treated as the benchmark because it can help you avoid lenders mortgage insurance, known as LMI. On a $600,000 home, that would be $120,000 before allowing for purchase costs.
However, many first home buyers purchase with less. Depending on the lender, your financial position and the property, it may be possible to buy with a 5 to 15 per cent deposit. A smaller deposit can help you enter the market sooner, but it usually means borrowing more and may mean paying LMI.
LMI protects the lender, not the borrower, if the property must be sold and the proceeds do not cover the loan. It is generally a one-off cost that may be added to your loan, although this increases the amount on which interest is charged. It is not automatically a bad outcome. For some buyers, paying LMI is a sensible trade-off if waiting several more years to save 20 per cent means prices or rents move further out of reach. For others, a longer saving period creates a more comfortable repayment and a stronger safety net. It depends on your circumstances.
A useful starting point is to consider three figures together: your deposit, your purchase costs and your post-settlement savings. Being able to contribute a deposit is valuable, but lenders also want to see that the home loan remains manageable when everyday bills, rate changes and unexpected expenses appear.
A simple deposit example
Say you are looking at a $700,000 home. A 10 per cent deposit is $70,000. Your loan would be $630,000, before any LMI that is added to the loan. You would then need funds for stamp duty and other transaction costs, unless you are eligible for a concession or exemption.
In Victoria, eligible first home buyers may receive stamp duty concessions or exemptions within certain property value thresholds. These rules, along with first home owner grants, are specific to the state and can change. The property type, its value and whether you plan to live in it all matter, so never build a budget around an assumed concession without confirming your eligibility.
What lenders look for beyond the deposit
A large deposit helps, but it is only one part of a home loan application. Lenders assess whether you can comfortably service the loan, not simply whether you can get the contract across the line.
They will look at your income, employment history, regular living expenses, existing credit limits, personal loans, car finance, dependants and repayment history. They also assess your application at an interest rate higher than the rate you will initially pay. This serviceability buffer is designed to test whether your budget could cope if rates rise.
The source of your deposit matters too. Lenders often prefer to see genuine savings, meaning funds you have built over time through regular saving. Rent paid consistently may be accepted as evidence of savings by some lenders, while gifts from family, bonuses, sale proceeds or an inheritance may be acceptable with the right documents. Each lender has its own policy.
This is why a buyer with a 10 per cent deposit and stable income may be in a stronger position than someone with 20 per cent saved but high ongoing commitments. A tailored loan strategy looks at the full picture.
Ways to build a stronger deposit position
Saving can feel slow when rent and living costs are already taking a large share of your pay. The most effective approach is usually practical rather than extreme: make the target visible, automate savings after payday and reduce expenses that do not add much value to your life.
It can also help to separate your deposit from your everyday account. A dedicated high-interest savings account makes progress easier to track and reduces the temptation to dip into it. If you receive a tax refund, commission payment or work bonus, deciding in advance how much goes to the deposit can build momentum without requiring a complete lifestyle overhaul.
Before applying, consider reducing high-interest debts and unused credit card limits where appropriate. Even a credit card you rarely use can affect borrowing capacity because lenders may assess the full limit as a potential commitment. Avoid taking on new finance for furniture, a car or holidays shortly before applying for a home loan. It may change your borrowing position at the wrong time.
Low-deposit options worth understanding
Low-deposit buying is not one single product. It may involve a standard loan with LMI, a lender-specific offer, family support or a government-backed guarantee program.
Eligible buyers may be able to access a government-backed 5 per cent deposit pathway, where the government guarantee can reduce or remove the need for LMI. Eligibility requirements, property price caps, participating lenders and places available can change, so it is essential to check the current rules before relying on a scheme.
A family guarantee is another option for some buyers. A parent or close family member may offer equity in their property as additional security, allowing you to borrow with a smaller cash deposit and potentially avoid LMI. This can be helpful, but it is a serious commitment for everyone involved. If repayments are not met, the guarantor’s property may be at risk. Clear conversations, legal advice and a defined plan to release the guarantee are vital.
First home owner grants can assist eligible buyers of new homes or substantially renovated homes, depending on the state or territory. They are not usually available for every first home purchase, particularly established properties, and should be treated as support rather than your entire deposit strategy.
Do not spend every dollar on settlement
It is tempting to put every available dollar into the deposit to reduce the loan amount. Yet keeping a sensible emergency buffer is often just as important. Appliances fail, moving costs add up, strata levies may arrive and new owners quickly find small jobs that need attention.
The right buffer differs for each household, but it should be enough to deal with a surprise without immediately relying on a credit card. Your mortgage repayment is only one part of home ownership. Council rates, insurance, utilities, maintenance and, where relevant, body corporate fees need a place in the ongoing budget.
A lender may approve a particular loan amount, but approval is not the same as affordability for your preferred lifestyle. You may choose to buy below your maximum so you can keep travelling, support children, grow your savings or simply sleep better at night. That is a financially sound decision, not a missed opportunity.
Turning a deposit target into a buying plan
Before inspecting properties seriously, work backwards from a realistic price range. Estimate your likely deposit percentage, add purchase costs, check potential concessions and assess the repayment at both current and higher interest rates. A pre-approval can then give you a clearer guide to your borrowing capacity, although it remains subject to the lender’s final assessment and the property itself.
At Lumbini Finance, we help first home buyers compare the real trade-offs across a broad lender panel, from deposit size and LMI to repayment flexibility and future refinancing options. The aim is not to force you into the biggest loan possible. It is to help you make a confident decision with a structure that supports your next chapter.
Your first deposit does not need to be perfect to be meaningful. With clear numbers, a realistic buffer and advice that reflects your goals, you can take the next step knowing what you are working towards and why.
