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

Figuring out how much to earn to buy a house South Africa banks will approve comes down to one simple rule most people have never heard explained plainly. Banks generally won't let your bond repayment go above 30 percent of your gross monthly income, before tax. That single number is the starting point for almost every home loan affordability South Africa decision a bank makes.

Here's what that looks like in real terms. If a bond repayment on your dream home works out to R6 000 a month, the bank wants to see that you earn at least R20 000 a month before tax to comfortably support it. It's not about what lands in your bank account after deductions and debt, it's your gross salary, the number before anything gets taken out.

A Real Example, Not Just a Rule

Let's put real numbers to this. On a R600 000 home loan at the current prime rate of 10.5 percent over 20 years, your monthly bond repayment comes to roughly R5 990. Using the 30 percent rule, that means you'd need a gross monthly income of around R20 000 to qualify comfortably.

That number matters for another reason too. It sits right at the upper edge of the income band for the FLISP subsidy, which supports buyers earning R3 501 to R22 000 a month with up to R169 264 towards their bond. If your income falls in that range, a home in this price bracket becomes even more achievable, since the subsidy shrinks the amount you actually need to borrow in the first place.

Why Your Debt to Income Ratio Matters Just as Much

Your salary isn't the only number banks look at. They also calculate your debt to income ratio, which is every existing monthly debt payment you have, like a car payment or store account, divided by your gross income. If that ratio sits above 40 percent, most banks will decline new credit outright, since it suggests you're already financially stretched.

This is why paying down existing debt before applying can make a bigger difference than people expect. Clearing a car payment or a store account doesn't just improve your credit record, it directly frees up room in your affordability calculation for a bigger bond, or makes qualifying possible at all.

What Actually Counts as Income

Banks look at your gross income from all reliable, provable sources, including:

• Your basic salary before tax and deductions

• Guaranteed allowances, if consistently paid

• A spouse or partner's income, if you're applying together

• Verifiable rental income, if you already own another property

They generally don't count irregular bonuses or overtime unless there's a consistent, documented history of receiving them.

The Salary Needed for a Bond, By Price Range

Here's a rough guide to the salary needed for a bond on a few common price points, based on the 30 percent rule at the current 10.5 percent prime rate over 20 years:

1. R500 000 home: repayment around R4 990 a month, requiring roughly R16 600 gross income

2. R600 000 home: repayment around R5 990 a month, requiring roughly R20 000 gross income

3. R750 000 home: repayment around R7 490 a month, requiring roughly R25 000 gross income

4. R1 000 000 home: repayment around R9 990 a month, requiring roughly R33 300 gross income

These are estimates, and your actual approval also depends on your credit record, existing debt, and each bank's own internal policy, according to ooba Home Loans' affordability guidance.

What to Do Before You Apply

If your income needed to buy a house feels just out of reach right now, a few practical steps can shift the numbers in your favour:

• Pay down or close any small store accounts and short-term debt

• Check your credit report for errors before applying

• Consider a 100% home loan if you don't have savings for a deposit, since it doesn't change your income requirement much but removes the deposit hurdle

• Apply through a bond originator who compares multiple banks at once, since affordability policies differ from bank to bank
