Understanding 100% Bonds in South Africa
South African banks will grant a 100% home loan (meaning no deposit required) to buyers who qualify based on income, credit score, and the property value relative to their income. This is not common in most other countries and is one reason South Africa has a relatively high home ownership rate.
However, 'no deposit' does not mean 'no cash.' You still need to pay transfer costs, which the bank does not finance. On a R1.5 million home, you're looking at R69,000–R87,000 minimum in cash at transfer — even with a 100% bond. Many buyers are caught off guard by this.
The other risk of a 100% bond is negative equity. If property prices dip in your area after you buy — which happens — you could owe more on your bond than your property is worth. A 10% deposit provides a buffer against this. It also immediately reduces your monthly repayment and the total interest you'll pay over the life of the loan.
How a Deposit Actually Saves You Money — The Real Maths
Let's run the numbers on a R1.5 million home at the current prime rate of 10.50% over 20 years. With no deposit (bond = R1.5m), your monthly repayment is approximately R14,980. Total interest over 20 years: approximately R2.1 million. With a 10% deposit (bond = R1.35m), your monthly repayment drops to about R13,482 — saving R1,498/month. More importantly, you'll likely get a better interest rate. At prime minus 0.5% (10.0%), the same bond of R1.35m is approximately R13,023/month. That's a saving of almost R2,000 per month versus a 100% bond at full prime.
Over 20 years, the person with a 10% deposit and a slightly better rate pays roughly R450,000 less in total interest than the 100% bond holder. That's not accounting for the rate reduction — purely the capital difference. When you include the rate benefit, the gap can easily exceed R600,000.
This is why financial advisors consistently say: if you can delay buying by 12–18 months to save a deposit, the long-term financial benefit often outweighs the short-term cost of renting during that period.
First-Time Buyer Tips for Saving Your Deposit
Use a TFSA for your deposit savings. Any growth (interest, dividends, capital gains) in a TFSA is tax-free, and you can withdraw the money when you need it for your property purchase without penalty. At the 2026 annual limit of R46,000 with a typical money market rate of 8–9%, your TFSA will compound meaningfully over 2–3 years.
Understand that pre-approval doesn't mean final approval. Banks pre-approve based on income and credit score, but the property still needs to be valued. If the bank values the property at less than the purchase price, you'll need to bridge the difference yourself.
Get bond quotes from multiple banks. Using a bond originator (like ooba or BetterBond) costs you nothing and ensures you get competing offers from all major banks. The difference between the best and worst offer can easily be 0.5%–1%, which is worth tens of thousands of rand over the loan term.
