The short answer is that there's no fixed minimum deposit required by law - but in practice, having a deposit significantly improves your chances of getting a home loan, and often results in a better interest rate.
Do You Need a Deposit at All?
South African banks do offer 100% home loans - meaning they'll lend you the full purchase price with no deposit. This is more common for first-time buyers, buyers with excellent credit profiles, and buyers with strong, stable incomes relative to the purchase price.
However, the availability of 100% bonds depends heavily on economic conditions and the bank's current risk appetite. During periods of higher interest rates or economic uncertainty, banks tend to require deposits more consistently.
If you're a first-time buyer relying on a 100% bond, don't count on it. Have a deposit target in mind and treat a 100% approval as a bonus.
What Difference Does a Deposit Make?
Approval probability. A deposit reduces the bank's risk. A buyer putting down 10% is less likely to default or be in a negative equity position than one borrowing 100%. Banks are more comfortable approving applications with deposits.
Interest rate. Banks offer better rates to lower-risk borrowers. A 10% deposit can improve your interest rate by 0.25% to 0.75% - and on a large bond over 20 years, that's a significant saving.
Monthly repayment. Obviously, borrowing less means paying less per month. A 10% deposit on a R1.5 million property reduces your bond from R1.5 million to R1.35 million - saving approximately R1,500 per month in repayments.
Deposit Benchmarks
5% deposit: Shows commitment, slightly improves your risk profile. On a R1.5 million property, that's R75,000.
10% deposit: The sweet spot for most applications. Meaningful risk reduction for the bank, noticeable rate improvement. R150,000 on a R1.5 million property.
20% deposit: Strongly positioned application. Likely to achieve prime minus rate. R300,000 on a R1.5 million property.
The Challenge for First-Time Buyers
Saving a deposit while paying rent is one of the hardest financial challenges for first-time buyers. The good news:
The government's FLISP subsidy (Finance Linked Individual Subsidy Programme) provides financial assistance for qualifying first-time buyers with a monthly income between R3,501 and R22,000. FLISP can be used as a deposit. Check eligibility through your bank or bond originator.
Family gifts. South African banks accept family gifts as deposits, subject to documentation. A gift letter and bank transfer evidence are typically required.
Don't forget transfer costs. Even a 100% bond doesn't mean you need zero cash. Transfer duty, conveyancer fees, and bond registration fees are not covered by the bond. Budget for these separately.
The Bottom Line
Aim for at least 10% deposit if you can. If you can't, apply with what you have - 100% bonds do exist and do get approved. But understand that a larger deposit improves almost every dimension of your application: approval likelihood, interest rate, monthly repayment, and long-term financial position.
