Yes — South African banks do offer home loans for properties you plan to rent out, not only for the home you'll live in. A buy-to-let (or “second bond”) application goes through the same core process as any home loan: a credit check, an affordability assessment and a property valuation. What typically changes is how closely the bank looks at two things — your deposit, and the income the property itself will generate.
How is a buy-to-let bond different from a bond on your own home?
The mechanics are the same reducing-balance bond you'd get on a primary residence, priced off the same prime rate. The difference is in underwriting. Because a rental property carries more risk for a lender — vacancy periods, maintenance, tenants who don't pay — South African banks generally ask for a larger deposit on a second or investment bond than on a primary residence, and assess the property's rental income more conservatively than its asking rent. Exactly how much larger the deposit needs to be, and how much rental income a bank will count, varies by lender and by your own credit profile — there is no single industry-wide figure, so treat any specific number you see elsewhere as an example, not a quote.
What does financing a rental property actually cost per month?
The repayment itself follows the identical annuity formula as any other South African bond. Here is what a rental property bond costs per month at the current prime rate, with no margin, over a 20-year term — recalculated from the standard formula, not copied from anywhere:
| Property / bond size | Monthly repayment at 10.75% |
|---|---|
| R 900 000 | R 9 137 |
| R 1 500 000 | R 15 228 |
| R 2 500 000 | R 25 381 |
These are estimates at prime with no margin, over a 20-year term — your actual rate depends on your bank, deposit and credit profile, and may sit above or below prime. To run the numbers for a specific property and rental income, use the bond repayment calculator.
Does the 30% affordability rule still apply to a second bond?
Yes, and it applies cumulatively. The affordability guideline South African banks work from caps your total bond instalment — generally taken as 30% of gross monthly income — across every bond you're servicing, not just the new one. If you're still paying off your own home, a bank will add the proposed rental-property instalment to your existing one (net of whatever rental income it allows you to count) before deciding what you qualify for. That is one reason a realistic deposit matters more on a second bond: it lowers the new instalment enough to fit inside what your income, net of your existing commitments, can still carry.
Is the interest on a rental property bond tax-deductible?
Generally, yes — under South African income tax principles, expenses you incur to earn rental income, including bond interest, rates, levies and maintenance on the let property, are typically deductible against that rental income. This does not apply to the bond on your own primary residence. The exact treatment depends on your personal tax position, how the property is held, and current SARS practice, so this is general information, not tax advice: confirm your own position with SARS or a registered tax practitioner before you rely on it in a tax return.
What should you do before applying for a second bond?
Three things, in order. First, get pre-approved so you know what you can realistically borrow against your existing commitments, not just your income. Second, confirm your full deposit in cash — a second bond is underwritten on top of your current bond, so the bigger deposit convention on investment properties is worth planning for rather than discovering at application stage. Third, run the actual repayment at prime and at a margin above it, because a rental property bond that only works at today's rate leaves you exposed at the next SARB decision. Our home loan deposit guide covers how deposit size changes what you qualify for, and the bond repayment calculator lets you stress-test a specific property before you make an offer.
