Rent increase versus retaining a reliable tenant in a Johannesburg duplex

The market gap looks significant. My concern is whether chasing it would cost more than keeping a tenant who pays reliably and looks after the home.

This is a three-bedroom Johannesburg duplex currently let for about ZAR 54,220, while similar properties are being advertised near ZAR 61,370. A jump to the listing figure could trigger vacancy, cleaning, reletting and refurbishment costs, but leaving the rent unchanged may allow the difference to grow.

I am considering a smaller increase now, followed by another review rather than one large adjustment. How would you test whether those advertised duplexes are truly comparable and present a fair proposal under the lease and local notice rules? I also need to account for the maintenance record and correct deposit handling.
 
I’d put a real price on retention before deciding. The gap is ZAR 7,150 per month, but even a short vacancy plus cleaning, repairs and reletting can absorb a lot of that difference. A staged increase below the asking-rent figure may be the sensible middle ground, particularly with reliable payment and good care of the home.
 
How did you arrive at ZAR 61,370? Are those genuinely comparable occupied duplexes, or just current listings with similar bedroom counts? Asking rent is not necessarily achieved rent. I’d compare location within Johannesburg, condition, parking, security features and what is included before treating that figure as the market level.
 
One more calculation: compare each proposed increase with the likely cost of turnover. For example, work out how many months of the additional rent would be needed to recover vacancy and refurbishment. That does not produce the answer by itself, but it makes the retention discount visible rather than emotional.
 
I’d be less conservative than Yuki. A good tenant has value, but allowing a large gap to remain can make the next review much harder for both sides. If the comparables survive Katarina’s questions, explain the evidence and propose a meaningful increase, perhaps phased if the lease and applicable rules permit. Reliability should influence the figure, not prevent a proper review.
 
Ivan’s point is fair, although I still wouldn’t anchor the discussion solely to ZAR 61,370. Fatima could present a clear renewal proposal below that amount and explain that it recognises the tenant’s record. Before sending it, confirm the required notice, whether the lease limits timing or increases, and what happens if the tenant does not accept the new amount.
 
The maintenance history matters too. Separate genuine owner maintenance from damage attributable to the tenant; otherwise the rent conversation can become tangled with disputed repair costs. I’d inspect by agreement, deal with outstanding items, then send a calm written proposal showing the current rent, proposed rent, effective date and basis for the change.
 
I would also keep the deposit out of the initial negotiation unless an increase actually requires it to be addressed under the lease and applicable South African rules. Don’t casually treat the existing deposit as extra rent or a refurbishment fund. Record any agreed change properly and confirm the correct handling before requesting an adjustment.
 
A practical way to decide is to model three cases: retain at ZAR 54,220, retain after a moderate increase, or seek a new tenant near ZAR 61,370. Put realistic vacancy, advertising, cleaning and repair assumptions against the third case. Then choose the proposal that still looks sensible if the property remains empty longer than hoped. That should show whether preserving this tenancy is worth more than closing the full headline gap.
