How Much Deposit Do You Need to Buy a House in South Africa?

By Finance Atlas Editorial  ·  Updated 30 June 2026

"How much deposit do I need?" is one of the first questions every home buyer asks — and the honest answer is that you may need less than you think to get approved, but more than you think to buy well. Here is how deposits really work in South Africa: when you can skip one, why putting something down still pays, and the cash you need regardless.

Can You Buy With No Deposit?

Often, yes. South African banks do offer 100% bonds that finance the full purchase price, and they are common for first-time buyers with a solid credit record and stable income. So a deposit is not always a barrier to getting onto the property ladder. But "can" and "should" are different questions — a no-deposit bond almost always comes with a higher interest rate, because the bank is taking on more risk.

Why a Deposit Still Pays

Even when you do not strictly need one, a deposit works in your favour in three ways:

• A better interest rate. A deposit lowers your loan-to-value ratio — the size of the loan relative to the property's value — which banks treat as lower risk. Lower risk usually means a better rate, and because the rate applies for 20 years, even a small improvement saves a lot.
• A lower repayment. You are borrowing less, so the monthly instalment is smaller and the total interest over the term drops.
• A stronger application. A deposit signals discipline and reduces the bank's exposure, which can make the difference between approval and decline for a borderline application.

The Cash You Need Regardless of a Deposit

Here is the trap that catches first-time buyers: the deposit is not the only upfront cash you need. Whether or not you put down a deposit, you must pay the once-off buying costs — transfer duty (a SARS tax above the threshold), bond registration, and transfer and bond attorney fees — and these are not covered by the bond. On a typical home they run to tens of thousands of rand. Work out the full figure with our transfer duty and bond costs calculator before you commit, so the costs do not ambush you after your offer is accepted.

How Much Should You Aim For?

There is no fixed rule, but a useful target is around 10% of the purchase price as a deposit, on top of your buying costs. That is usually enough to earn a meaningfully better rate without delaying your purchase for years. If 10% is out of reach, do not be discouraged — even 5% helps, and a 100% bond is a legitimate route onto the ladder. The right number is the one that balances a better rate against buying while prices and your circumstances suit you.

How to Save the Deposit

Saving a deposit is a medium-term goal, so where you keep the money matters. A tax-free savings account shelters the growth from tax, and the power of compounding means starting earlier beats saving harder later.

Frequently Asked Questions

Can I buy a house with no deposit?

Yes — 100% bonds are available, especially for first-time buyers. You will still need cash for transfer and bond costs, and the rate is usually higher than with a deposit.

Does a deposit lower my interest rate?

Usually. A deposit lowers your loan-to-value ratio, which banks see as lower risk, so they often offer a better rate — saving you interest across the whole term.

Is the deposit the only upfront cash I need?

No. Transfer duty, bond registration and attorney fees are separate and not covered by the bond, so budget for them in cash too.
