To see how much you could borrow first, use the borrowing power calculator, and for stamp duty on its own, the stamp duty calculator.
The deposit is not the whole number
Those costs do not come back. The deposit buys part of the home. The costs are spent. Stamp duty is charged on the price, not on your deposit, so a smaller deposit does not make it smaller.
= deposit + stamp duty + registration fees + lender fees + lenders mortgage insurance (if paid upfront) + conveyancing, inspections and other costs
Use the contract price for the deposit and for stamp duty. If you can add lenders mortgage insurance to the loan, your upfront cash falls, but your loan is bigger.
First, most of these costs have to come from your own savings. Lenders mortgage insurance is the one that some lenders allow you to add to the loan.
Second, and this is where most published advice goes wrong, a smaller deposit does not mean smaller costs. It usually adds lenders mortgage insurance, and a bigger loan. ING notes that a lender might let you borrow more so you can cover stamp duty with less deposit, and that this usually brings lenders mortgage insurance with it.

Worked example: $650,000, four ways to buy it
Take a $650,000 home in South Australia. Stamp duty on an established home is $29,580, registration fees are about $6,666 and other costs are $3,500, so the costs on top of the deposit are $39,746.
1. Established home, 20 per cent deposit
Deposit $130,000. No lenders mortgage insurance. Cash to settle $169,746. Loan $520,000.
2. Established home, 10 per cent deposit
Deposit $65,000, so cash before insurance is $104,746. Loan $585,000. Lenders mortgage insurance at 1 to 3 per cent of the loan is about $5,850 to $17,550, which some lenders let you add to the loan.
3. Established home, 5 per cent deposit through the Australian Government 5% Deposit Scheme
For eligible first home buyers within the price cap. Deposit $32,500, no lenders mortgage insurance, cash to settle $72,246. Loan $617,500.
4. New home, eligible first home buyer, 5 per cent deposit
No stamp duty for eligible first home buyers of new homes. Deposit $32,500 plus registration and other costs is $42,666. The First Home Owner Grant of up to $15,000 would take that to $27,666.
Same price, and the cash needed ranges from $27,666 to $169,746. The loan goes the other way, from $520,000 to $617,500.

About the figures on this page. Stamp duty is the RevenueSA scale, for example $21,330 plus 5.50 per cent of the amount above $500,000, which gives $29,580 at $650,000. Registration fees are the Land Services SA transfer registration fee from its 2025-26 scale, the latest available when this page was built ($6,462 at $650,000, rising $102 for each further $10,000 of price, so expect it to be a little higher now), plus the $204 mortgage registration fee for 2026-27. Other costs of $3,500 and lenders mortgage insurance at 1 to 3 per cent of the loan are illustrative assumptions, not quotes, and the registration fee may differ on a transfer with no stamp duty payable.
Property buying cost questions, answered
How much do I need on top of my deposit to buy a house?
In South Australia, about 6 per cent of the price on an established home. On a $650,000 home the costs on top of the deposit come to about $39,746: stamp duty of $29,580, registration fees of about $6,666 and $3,500 for conveyancing, inspections and moving. Lenders mortgage insurance is extra if you borrow more than 80 per cent.
How much is stamp duty in South Australia?
It is charged on a sliding scale by RevenueSA. The top bracket is $21,330 plus $5.50 for every $100 or part of $100 over $500,000, so a $650,000 home pays $29,580. The same scale applies to owner-occupiers, investors and first home buyers of established homes. The stamp duty calculator shows yours.
Do first home buyers pay stamp duty in South Australia?
Not on a new home, an off-the-plan apartment or vacant land if they are eligible, as RevenueSA offers relief for those. On an established home there is no first home buyer relief and full duty applies. Check eligibility with RevenueSA before you choose between a new and an established home.
What is the First Home Owner Grant in South Australia?
A one-off payment of up to $15,000 for eligible first home owners buying or building a new home to live in, according to RevenueSA. It is separate from stamp duty relief and you apply for each separately. You must live in the home as your principal place of residence for at least six continuous months. Eligibility rules change, so confirm them with RevenueSA.
What is lenders mortgage insurance and when do I pay it?
It protects the lender if you borrow more than 80 per cent of the price and cannot repay. One guide puts the cost at 1 to 3 per cent of the loan, so on a $585,000 loan that is about $5,850 to $17,550. You usually pay it once, and some lenders let you add it to the loan. The bigger your deposit, the less you pay, and above 20 per cent you usually pay none.
Can I buy with a 5 per cent deposit and avoid lenders mortgage insurance?
Possibly. The Australian Government 5% Deposit Scheme, also called the First Home Guarantee, lets eligible first home buyers buy with a 5 per cent deposit without paying lenders mortgage insurance. Since October 2025 it has had no income cap and no cap on places, but price caps apply, it is accessed through participating lenders and you still pay stamp duty on an established home. Your loan is larger, so check the repayment.
What are the registration fees in South Australia?
Two fees go to Land Services SA. The transfer registration fee is set by the price, and on the 2025-26 scale it was $6,462 for a $650,000 home, rising $102 for each further $10,000. The mortgage registration fee is $204 for 2026-27. Your conveyancer will confirm both for your purchase.
Can I add the buying costs to my loan?
Usually only some of them. Lenders mortgage insurance can often be added to the loan. Stamp duty, registration and conveyancing generally have to come from your own savings, although a lender might let you borrow more against a smaller deposit, which usually brings lenders mortgage insurance with it. Ask your broker what each lender allows.
Are the costs different for an investment property or a foreign buyer?
In South Australia the stamp duty scale is the same for owner-occupiers and investors, but first home buyer relief and the grant are for a home you will live in. Foreign purchasers pay a 7 per cent foreign ownership surcharge on top of duty. Investors may also face land tax, which the tool covers as a separate line.
Do you charge a fee to arrange a home loan?
We do not charge you a fee for arranging your home loan. Brokers are generally paid a commission by the lender when the loan settles. Lenders may charge their own establishment, annual or package fees, and those are disclosed to you before you commit. If any fee from us would ever apply, you would be told in writing beforehand.
