Property listings show what landlords are asking. They don't show what tenants are actually paying.
When it is time to price a vacant rental, most landlords do the same thing. Open a property portal such as Property24 or Private Property, look at a few similar listings nearby, and pick a number somewhere in the middle. It feels like research, and it is a sensible place to start. The catch is what those listings are: the rent other landlords are asking, for units that haven't found a tenant yet.
Asking rent is the number a landlord chose. Achieved rent is the number a tenant agreed to. The closer your price sits to the second one, the less likely you are to face an empty month.
Why portal listings are a starting point, not the answer
Think about which units stay visible on a portal the longest. The ones that let quickly come down. The ones that linger tend to include those asking more than tenants will pay, although the unit's condition and presentation matter too. So a page of current listings can lean towards the expensive end of the market. That makes asking rents a starting point for working out your own rent, not a verdict on it.
What tenants are actually paying
Three sources give a better picture than any listing. They don't agree exactly, but together they show the range.
| Source | What it measures | Latest reading |
|---|---|---|
| Stats SA | Rent changes in its official consumer price index | Up 4.1% in the year to June 2026 |
| PayProp Rental Index | Average rent across agent-managed rentals PayProp processes | Up 5.2% in Q2 2026, to R9 715 |
| TPN (forecast) | Its expected residential rent escalations for 2026 | 4.5% to 5.5% |
Stats SA is the official measure, and it splits rent growth by dwelling type: in the year to June, townhouses rose 5.4%, flats 4.6% and houses 3.7%. PayProp's index is built from rent payments it processes for agent-managed rentals, so it records what tenants paid rather than what was advertised. It covers those rentals, not every rental in the country. The three follow different samples and methods, so they won't match. Read together, they point to rent growth of roughly 4% to 5% a year, which shows how big a premium the market has been bearing.
Averages also hide a lot. In PayProp's second quarter figures the Western Cape grew 9.7%, to an average of R12 561, and PayProp calculates that without it national growth would have been 4.3%. One province moved the national figure by almost a percentage point, which is why a national average is a weak guide to a single street.
How long an empty rental usually stays empty
TPN's Vacancy Survey for the third quarter of 2024 put national vacancies at 5.07%. That works out to under three weeks a year for the average unit. The spread was wide, from 1.07% in the Western Cape to 7.12% in KwaZulu-Natal, and units renting between R7 000 and R12 000 had the lowest vacancy of any rent band, at 3.4%. The survey is two years old, so the exact numbers will have moved, but the big differences between provinces and rent bands are the useful part.
What matters is not the highest number you can list at. It is how quickly the unit lets at the number you choose. A unit that stays empty for much longer than a few weeks has a reason, and the price is one of the possible ones, alongside condition, photos and timing.
What an overpriced rental costs over a year
Take the same two-bedroom sectional title unit from Are you actually making money?, renting at R11 000 a month. Say you list it at R11 800 because it doesn't hurt to try, and at that price it takes 10 weeks to find a tenant. Over a 52-week year, that leaves 42 weeks of rent: R11 800 × 12 ÷ 52 × 42 = R114 369.
Price it at R11 000, in line with what similar units are achieving, and say it lets in three weeks. That leaves 49 weeks of rent: R11 000 × 12 ÷ 52 × 49 = R124 385.
| Scenario | Monthly rent | Weeks empty | Rent collected over the year |
|---|---|---|---|
| Priced R800 above market | R11 800 | 10 | R114 369 |
| Priced at market | R11 000 | 3 | R124 385 |
The lower price brings in roughly R10 000 more over the year. These timings are examples. Your own unit could let faster or slower. The useful number is the break-even. An R800 premium is worth R9 600 over a full year, and once the higher price adds a little over three weeks to the time it takes to let, the extra rent no longer covers the weeks lost.
Banks know this one. A lender charging a few points above everyone else doesn't earn a better margin, it simply doesn't win the loan. A rent above the going rate works the same way: the extra rand isn't profit waiting to be collected, it is a delay in when any rent starts coming in.
What has changed this year
Stats SA's figures show rents up 4.1% in the year to June, a month when headline inflation reached 5.0% (it has since eased to 4.4% in August). PayProp's figures show rents narrowly ahead of inflation instead. Either way, the cushion is thin.
Tenants are under more pressure too. Stats SA's labour force survey put unemployment at 33.6% in the second quarter, up from 32.7% in the first. The Reserve Bank raised interest rates in May and again in September, taking the prime rate to 10.75%. PayProp expects the May increase to push up tenants' debt repayments. The share of tenants in arrears in its index was 16.9% in the second quarter, up from the record low of 16.7% in the first.
None of this means rents should fall. It does mean that pricing above what local tenants can comfortably afford carries more risk than before: a longer wait to let, and a higher chance of late payment once someone moves in.
Where the number for your own street comes from
Listings show asking prices, set by landlords, for units that are still available. Stats SA and PayProp show what rents have actually done. One is a wish list. The other is a record. Their figures stop at national or province level, so for your own street the closest check is what a local agent says comparable units have actually let for recently, set beside the listings you are competing against.
What Usika shows
Usika doesn't set your rent. It keeps your own record, which is the number the portals can't give you. The rent register shows what each tenant paid in each month, and a property's Overview shows its net income from the rent collected and the costs you have logged. Both are free.
After a few lettings, that record shows how many weeks each unit stood empty at each price. It also feeds the yield figure in Are you actually making money?, because vacancy is one of the costs that calculation includes.
