What Deposit Do You Need for a House in South Australia in 2026?
If you are planning to buy your first home in South Australia this year, one of the biggest questions you will have is how much deposit you actually need. Thanks to national and state programs, it is now possible for many first home buyers to get into the market with a deposit as low as 5%.
In this article, we will explain how the new 5% rule works, what lenders are looking for, and how you can take advantage of current government support to buy your first home sooner.
How the 5% Deposit Rule Works
Traditionally, home buyers needed a 20% deposit to avoid paying Lenders Mortgage Insurance (LMI). That meant saving $120,000 for a $600,000 home, which was a major barrier for many South Australians.
Now, through the Home Guarantee Scheme, eligible first home buyers can purchase a home with a 5% deposit and pay no LMI. The federal government acts as a guarantor for up to 15% of the property’s value, which reduces the risk for lenders and helps you qualify with a much smaller deposit.
For example:
- Property price: $600,000
- 5% deposit: $30,000
- Government guarantee: 15% ($90,000)
- Loan amount: $570,000
That is a saving of around $20,000 to $30,000 in avoided LMI costs for many borrowers.
Government Support for First Home Buyers in South Australia
If you are buying in South Australia, there are additional programs you can combine with the 5% deposit rule:
- First Home Owner Grant (FHOG): A $15,000 grant for first home buyers building or purchasing a new home valued up to $650,000.
- Stamp Duty Relief: First home buyers purchasing or building new homes under $650,000 pay no stamp duty, saving up to $30,000.
- Regional Home Guarantee: Available for eligible buyers purchasing in regional South Australia, allowing you to build or buy a new home with a 5% deposit.
These programs can significantly reduce your upfront costs, helping you buy your home faster than you might expect.
How Much Should You Aim to Save?
Even with the 5% rule in place, it is important to plan for more than just your deposit. You should still budget for:
- Stamp duty (if not eligible for concessions)
- Conveyancing and legal fees
- Building and pest inspections
- Loan application fees
- Moving costs and setup expenses
If your purchase price is $600,000, a 5% deposit equals $30,000. To be safe, aim for $35,000 to $40,000 total savings to cover all other costs and have some buffer for settlement.
Is It Better to Save 20% or Buy with 5%?
Saving a 20% deposit will always put you in a stronger financial position because you borrow less and avoid long-term interest. However, waiting years to save that amount could mean missing out on your ideal property as prices continue to rise.
The 5% deposit rule allows you to enter the market sooner, start building equity, and potentially refinance later once your property value grows. If you have stable income and can manage repayments comfortably, buying with 5% can be a smart move.
A broker can help you compare both paths and decide whether entering the market now or saving longer suits your situation better.
Tips to Reach Your Deposit Goal in 2026
If you are still building your savings, here are a few simple strategies to help you reach your target faster:
- Automate your savings: Set up a separate account just for your deposit and transfer funds automatically each payday.
- Track your expenses: Small adjustments in spending can make a big difference over time.
- Use government schemes: Apply early, as some have limited spaces available each financial year.
- Consider co-ownership or guarantor options: Family guarantees can help you enter the market sooner.
- Stay consistent: Regular savings, even small ones, build momentum faster than waiting for large lump sums.
