Valuation check: 70 m² new-build flat in Johannesburg, asking ZAR 10,650,000 / flood-risk

The asking figure looks difficult to support from the evidence I have, and possible flood exposure is the concern I do not want the price discussion to obscure. This is a roughly 70 m², three-bedroom new-build flat in Johannesburg at ZAR 10,650,000. The light and location appeal to me, although the finishes seem average rather than exceptional.

There are three comparable listings but only one completed transaction, so I am wary of treating seller expectations as market value. I would like to compare the actual sale first, then adjust for exact location, usable floor area, condition and any parking included. Lease length or tenure details, flood information and an insurance indication may matter more than a neat price-per-square-metre calculation.

Which of those facts would you establish before deciding whether the flat is worth pursuing? I will still arrange a local appraisal before relying on a valuation.
 
The ask works out at roughly ZAR 152,000 per m², but I would not apply that rate mechanically. Start with the completed sale, provided it is genuinely comparable, and treat the three listings mainly as evidence of seller expectations. Actual achieved prices matter more.
 
How close is the completed sale: same building or development, similar floor, orientation and sale date? In this case, “Johannesburg” is far too broad. Exact micro-location could change the conclusion more than a modest difference in floor area.
 
I’m stuck on “new-build” combined with “dated finishes” and “average condition.” Is it a recently completed building with a dated specification, or an older unit being marketed as newly refurbished? Those are different condition adjustments.
 
For condition, I would avoid an arbitrary percentage. List the visible differences from the sold comparable, attach realistic remedy costs where possible, then add a low/base/high allowance for the items that are matters of taste rather than defects.
 
The flood point needs separating too. Is there evidence concerning this specific building or unit, or is it only a broad map indication? A generic flood-risk label is not enough to calculate an adjustment, but a clear insurance limitation or recurring cost could be material.
 
My biggest missing fact would be whether ordinary cover is available for the flat on acceptable terms. Not because insurance alone establishes value, but because it tests whether the flood concern has a real ownership cost rather than being a theoretical warning.
 
I partly disagree that condition should lead the analysis. At 70 m² for three bedrooms, layout efficiency may matter more than the finishes. A well-lit but cramped plan can compare badly with a slightly larger two-bedroom unit even after a neat per-square-metre adjustment.
 
Good point. Javier, do the bedrooms function as proper bedrooms once storage and circulation are considered? Gross floor area can conceal unusable passages, narrow rooms or limited cupboards. I would compare the internal plan before assigning the same rate per square metre.
 
Also check whether any balcony, terrace or other outdoor space is included in the stated 70 m². If one comparable counts outdoor area differently, its apparent rate per square metre will be misleading.
 
A simple comparison grid would help: completed or asking price, date, internal area, floor, outlook, light, condition, parking, outdoor space, monthly charges and exact location. Keep each adjustment visible rather than blending everything into one unexplained discount.
 
Before considering lease length, confirm the form of tenure. That question may not apply in the same way to every Johannesburg flat. Whatever the structure, the remaining term or ownership restrictions should be compared consistently rather than imported from another market’s valuation habits.
 
I would also ask whether the one completed sale was an ordinary open-market transaction and whether its condition at sale is known. One achieved price is valuable, but it can anchor the whole exercise incorrectly if its circumstances were unusual.
 
What are the service charges, and what do they include? Two visually similar flats can support different prices if one carries materially higher ongoing building costs. Any known upcoming expenditure would also belong in the affordability calculation, separate from the headline valuation.
 
Parking needs its own line rather than being buried in the overall comparison. Does the subject have a space, and do the comparables have the same arrangement? The adjustment should come from relevant local evidence if available, not a generic citywide amount.
 
I would resist converting flood risk directly into a fixed percentage. Building access, parking level, drainage history and insurability could affect two nearby flats differently. Get the concern defined first; otherwise the adjustment gives false precision.
 
So far the defensible order seems to be: verify the completed sale, establish exact micro-location and layout comparability, reconcile the area measurements, then deal separately with condition, parking, outdoor space, charges and flood-related ownership costs. The asking listings should sit behind that work, not drive it.
 
Practical next step: request the floor plan and area basis for all four comparables, plus the subject’s recurring charges and parking details. Then ask an insurer about the specific property. That should expose whether the uncertainty is mainly valuation noise or a genuine cost issue.
 
For condition grading, photographs and an itemised comparison are more useful than “average” or “dated.” Compare kitchens, bathrooms, flooring, windows and built-in storage individually. A fashionable finish may attract buyers without being worth its full replacement cost.
 
At about ZAR 152,000 per m², even a small area error has a noticeable effect if you use the asking rate. Confirm that 70 m² is measured on the same basis as every comparable before making any floor-area adjustment.
