How Much Bond Can You Afford in South Africa?
Okay, so how much bond can you actually afford in South Africa?
As a guideline, South African banks generally won't let your total bond repayments go much past about a third of your gross monthly income, after a full affordability check of your other debts and expenses. For investors, that slice is the ceiling: every bond in your own name comes out of it. Buying through a company doesn't take you out of the assessment, but the bank also weighs what the property earns.
Around 2015, 2016, I hit that ceiling myself. A couple of banks said an outright no. Most just made it hard: no 100% bond, a higher interest rate, more paperwork, more waiting. A no dressed up as a maybe. I'll be honest, I went into victim mode for a bit. Why me?
It wasn't me. It was arithmetic.
What's the rule of thumb for bond affordability?
There's no single legal percentage. Under the National Credit Act, lenders must do an affordability assessment: your income, your existing debts and your living expenses. In practice, many banks use roughly 30% of gross income as a guideline for bond repayments.
Treat it as a ballpark, not a promise. Each bank, and each applicant, is different.
Illustrative example
Illustrative only: assumes an 11% interest rate over 20 years. Use your bank's calculator for real figures.
A R1,000,000 bond costs roughly R10,300 a month.
At about 30% of gross income, that needs roughly R34,400 gross income a month.
A R1,100,000 bond costs roughly R11,350 a month, needing about R37,800.
Now add your own home's bond, your car and your credit card. That's where the ceiling arrives. Yoh.
Eish, why do investors hit the ceiling so fast?
Because every repayment comes out of the same slice.
Your home. Rental number one. Rental number two. When the slice is full, the answer is no, however good the next deal is, and however reliably your tenants pay.
And the slice is under more pressure than it used to be. Electricity is up about 85% since 2020 and water about 68%, while rents rose only about 15% (Stats SA figures, via TimesLive, April 2026). Every one of those increases eats into the same affordability test.
That's the affordability ceiling most investors meet around property two or three. It isn't about how well you run your money. It's the size of one slice of one salary.
The other cost nobody mentions is time. In my own name I could only do one deal at a time: buy, fix, sell, wait for the affordability to free up, go again. Sequential, not parallel.

What changes when a company buys?
When a property is bought inside a company:
You still sign surety. The bank still assesses you, your credit and your existing debt.
But the bank also weighs what the property earns: the rent, the occupancy and the deal itself.
The new bond is assessed as a company's property debt, not just as another line on your personal payslip.
It doesn't make lending automatic, and it doesn't take you out of the picture. It changes what's on the scale. Same person, different question.
How can you improve your affordability?
Pay down short-term debt. Car finance, cards and store accounts all eat into the slice.
Clean up your credit record. Pull your report from one of the credit bureaus before the bank does. Late payments still count against you.
Arrive with a strong deal and clean paperwork. A well-bought property with a verified rent is easier to approve. By my third company purchase I had a ready-made document pack on my PC, and it made a real difference.
Use an originator who can present your application, especially a company application, properly. Mine once fought a bank for a better rate on one of our properties.
What I'd watch for
No outcome is certain. Every bank decides for itself.
Interest rates move. A deal that's affordable today may not be after a rate hike. Stress-test it at a higher rate before you sign.
More debt means more risk. A higher ceiling is only useful if the deals carry themselves.
Where the company fits
If you plan to own more than one or two properties, decide on the container before property one. Moving properties from your own name into a company later is possible, but it involves the bank, transfer costs and tax advice.

FAQ
How much should my bond repayment be compared to my salary?
Many banks use about 30% of gross monthly income as a guideline, after a full affordability assessment. It varies by bank and applicant.
Why was my second home loan declined?
Usually because your existing debt, including your first bond, already uses most of your affordability. Your credit record, the valuation and the property itself also matter.
Does buying in a company increase how much I can borrow?
It can change the assessment, because the bank also weighs what the property earns. You'll still usually sign surety and be assessed yourself.
Does a deposit improve affordability?
A deposit reduces the loan and the repayment, which can help. But it also uses cash you might need as a buffer.
