Property costs outpace rental income: what the UK squeeze means for SA landlords watching their margins

Our take

While this data comes from the UK, the underlying pressure it describes will feel familiar to South African buy-to-let landlords. Here, repair and maintenance costs have also climbed sharply — driven by load-shedding damage to appliances and electrical systems, water infrastructure failures, and general building material inflation. Meanwhile, rental growth in many SA metros has been modest, with tenants under their own affordability strain. For SA landlords, the parallel lesson is clear: if you are not actively tracking your expense-to-income ratio, you may be running a loss without realising it. The Rental Housing Act requires landlords to maintain properties in a habitable condition, so deferring maintenance is not a legal option — it is a liability. Buy-to-let investors evaluating new purchases should stress-test yields against realistic running costs, not just bond repayments. With the South African Revenue Service increasingly scrutinising rental income declarations, accurate expense tracking is both a financial and compliance necessity. Agents advising landlord clients should be having frank conversations about portfolio sustainability — especially for those holding older stock in high-maintenance suburbs. The question is not whether costs are rising; it is whether your rental pricing strategy has kept pace.
