How Much Deposit Do You Really Need for a Home Loan — and How to Get There Faster

If you’re asking how much deposit you really need and wondering whether saving it is even realistic, you’re in the right place.

The short answer is that many home buyers still aim for a 20% deposit because it helps you avoid Lenders Mortgage Insurance (LMI). But that number isn’t set in stone — and for a growing number of Australians, a much smaller deposit is now an option, particularly if you can tap into one of the government-backed schemes designed to get people into homes sooner.

At OzLoan, we spend our time tracking lender policy, government program changes and practical ways to move closer to a home loan — all researched carefully and written in plain English. We don’t lend money, we don’t promise approval or a particular rate, and we can’t give you personal financial advice. What we can do is walk you through how the deposit rules work, what genuine savings look like, and where to look for help so you can shape a plan that fits your own situation.

What counts as ‘enough’ in today’s market

For most standard home loans, lenders set a deposit threshold at 20% of the property value. When you borrow more than 80% of the value — in other words, when your deposit is smaller than 20% — the lender typically requires LMI. LMI is a one-off cost that protects the lender if you can’t repay the loan; it does not protect you.

That’s why a 20% deposit has become the default savings target. But it’s not the only path. A growing number of government-supported options let you buy with a lower deposit without taking on that extra LMI cost. Those options are worth understanding, because they can bring your home-buying timeline forward by years.

Government schemes that can lower your deposit requirement

The Australian Government’s First Home Buyers hub brings together three programs that can meaningfully reduce the deposit you need:

• Australian Government 5% Deposit Scheme. Formerly known as the Home Guarantee Scheme, this lets eligible first home buyers purchase with a minimum 5% deposit and no LMI. Single parents can buy with a minimum 2% deposit. There are now no income caps and unlimited places. You can use it to buy a house, townhouse or unit, whether new or existing.
• Help to Buy Scheme. This newer shared-equity scheme opens applications from 5 December 2025. You can buy with as little as a 2% deposit, and the government contributes up to 30% or 40% towards your purchase. It’s open to both first and previous homeowners, and you can repay the government contribution when you’re able to or when you sell.
• First Home Super Saver Scheme. This is designed to help you build a deposit faster by making voluntary contributions into your super fund — up to $50,000 plus associated earnings — and accessing them later under lower tax rates. You can use it alongside the other government schemes, and you can buy with a partner, sibling or friend.

State and territory governments also offer the First Home Owner Grant, a one-off payment that started in 2000. The grant amount and eligibility vary depending on where you’re buying, so it’s worth checking the details for your state or territory.

Genuine savings: what lenders are looking for

Even if you’re aiming for a smaller deposit through a scheme, lenders still want to see that you can manage money. Many ask for evidence of ‘genuine savings’ — funds you’ve accumulated over time rather than a sudden lump sum.

Genuine savings can typically be shown through:

• a pattern of regular deposits into a savings account over at least three to six months
• shares or managed funds held for a reasonable period
• rental payment history, where the lender accepts it as a proxy for savings discipline (policies vary)

Gifts from family, inheritances or proceeds from selling a car usually need to sit in your account for a while before a lender treats them as genuine. Each lender has its own policy here, so it’s an area where doing your homework early can save you a setback later.

Everyday ways to grow your deposit

Government schemes are incredibly helpful, but you still need to accumulate the funds for your deposit and buying costs. Small, consistent moves tend to add up more than radical but short-lived changes.

• Track where your money actually goes. Before cutting anything, spend a month watching your transactions. You’ll often find a handful of recurring costs that don’t match the value they deliver.
• Make saving automatic. Set up a separate high-interest account and have a fixed amount land there the day after payday. Even $100 a week adds up to $5,200 in a year — and the habit is what lenders notice.
• Use your tax return and windfalls intentionally. A tax refund, a bonus or a cash birthday gift can shave months off your timeline if you direct it straight into your deposit fund rather than letting it fall into everyday spending.
• Check if you’re leaving money on the table. The First Home Super Saver Scheme is often overlooked. If you’re in a position to salary-sacrifice extra into super, you may be able to grow your deposit faster thanks to the concessional tax treatment.
• Keep credit cards and other debts lean. When a lender calculates your borrowing capacity, existing credit card limits — even if unused — reduce how much you can borrow. Keeping limits low or cancelling cards you don’t need can strengthen your profile.

Putting the pieces together

The deposit you need isn’t a single number — it’s shaped by property prices where you’re buying, the lender’s policies and the government programs you’re eligible for. A 20% deposit remains the benchmark that avoids LMI, but a well-chosen scheme can bring that figure down to 5% or even 2%, without the extra insurance cost.

What matters most is building a savings record that shows consistent, genuine effort. Lenders want to see you can sustain the commitment, not just that you’ve hit a number once.

OzLoan’s calculators — including our borrowing power estimator and stamp duty tool — are free to use and can help you model different deposit sizes and purchase prices. They don’t ask for your email, and they don’t represent an offer of credit.

When you’re ready to explore whether a particular scheme or lender might work for your numbers, the next step is typically a conversation with an authorised credit representative who can look at your full financial picture. Until then, the most valuable thing you can do is keep adding to that deposit and keep asking questions — because the market changes often, and the right answer today might look different six months from now.
