Property investment is judged on what the asset earns after every cost, not on what it is worth. A first-time investor who compares rent against the bond repayment and stops there will discover the real position through rates, levies, maintenance, vacancy and a tenant who stops paying, all of which come out of the same rent.
Do the arithmetic before looking at anything.
Calculate the full cost, not the bond
Bond repayment, rates and taxes, levies where sectional title, insurance, maintenance, letting agent fees if used, and an allowance for vacancy. Then compare that total against realistic rent rather than the best-case figure.
Budget for vacancy specifically. A property empty for two months a year loses a meaningful share of annual income, and first-time investors routinely model twelve months of rent.
Location and tenant type determine the risk
Proximity to transport, work and amenities determines both what you can charge and how quickly you re-let. A cheaper property that stands empty earns less than a dearer one that does not.
Different tenant markets behave differently: residential family lets are stable and slower to re-let; student accommodation yields more with annual turnover and seasonal gaps; short-term letting yields most and is a hospitality business rather than a passive investment.
Understand what you are buying with sectional title
Levies fund the body corporate and can increase, and special levies for major work can arrive unexpectedly. Check the body corporate’s financial position and any planned maintenance before buying.
Scheme rules may also restrict letting, particularly short-term letting, which can invalidate the entire plan. Read them rather than assuming.
The obligations that come with a tenant
Lease agreements, deposits held and accounted for properly, and the incoming and outgoing inspections required by rental housing law. Eviction is a court process and takes time, so a non-paying tenant is a months-long problem rather than a weeks-long one.
Rental income is taxable with allowable expenses deductible, so keep records from the first month and confirm your position with the South African Revenue Service. Where you buy a share of a property or fund rather than a building, you are buying a financial product, and the provider should be authorised with the Financial Sector Conduct Authority.
Frequently asked questions
What should I calculate before buying?
Bond, rates, levies, insurance, maintenance, agent fees and a vacancy allowance against realistic rather than best-case rent.
Why budget for vacancy?
Because a property empty two months a year loses a meaningful share of annual income, and most first-time models assume twelve months of rent.
Which tenant market should I choose?
Residential is stable, student yields more with seasonal gaps, and short-term letting yields most but is a hospitality business rather than passive.
What should I check in a sectional title scheme?
The body corporate’s financial position, planned maintenance, the risk of special levies, and whether scheme rules restrict letting.
What happens if a tenant stops paying?
Eviction is a court process taking months, which is why tenant selection and a proper lease matter more than the purchase price.
