KES 116,700,000 is the figure making me pause. The Nairobi duplex has five bedrooms and about 195 m², which works out near KES 598,000 per m² before accounting for parking, terraces or other differences.

Natural light and location are its advantages; the finishes are dated, and the possible property-tax burden needs checking. I have three current asking prices for comparison, but just one completed sale. Should I adjust the floor areas onto the same basis first and then deduct identifiable condition costs? I would also like to know whether exact micro-location, remaining lease length, service charges or the treatment of parking could shift the result most. This is only a working estimate before a local appraisal.
 
The evidence is thin, so I would not let a broad price-per-square-metre calculation drive the decision. The single completed transaction is still the better provisional anchor, while the three current listings mainly show where sellers are testing the market.

First verify that the sale uses the same floor-area definition and treatment of parking. Then cost the visible work rather than applying a standard condition discount. Exact micro-location may move the range most, but a lease or service-charge difference could make an apparently close comparison unusable.
 
I would want the tenure details and remaining lease length before settling on micro-location as the answer. Service charges also matter because two similar duplexes can have very different ongoing costs. Do you know whether the 195 m² is internal floor area, and whether parking or terraces are included in that figure?
 
Those area definitions are crucial. If the completed comparable reports internal space while the subject includes a terrace or parking allocation, the apparent price-per-square-metre difference will mislead you. I would verify both measurements first. For condition, split dated decoration from items that actually require replacement; buyers do not discount every old finish by the full cost of installing a new one.
 
I would not automatically put lease length ahead of everything else. Parking, usable outdoor space and the precise part of Nairobi could outweigh a modest condition difference for the likely buyer. Also compare layouts, not just total area: fitting five bedrooms into 195 m² may produce a different value response from a less subdivided duplex of similar size.
 
A simple adjustment sheet would help. Put the completed sale and subject side by side for sale timing, micro-location, verified internal area, condition, lease length, service charges, parking and outdoor space. Mark each difference as positive or negative before assigning money to it. That makes it harder to force the evidence toward the KES 116,700,000 asking price.
 
For floor area, I would avoid multiplying the entire 195 m² by one average rate. First calculate the completed comparable’s implied rate, then consider whether its extra or missing space is equally useful. A larger corridor, terrace or awkward room does not necessarily carry the same marginal value as core living space. The per-m² result is best used as a cross-check.
 
Agreed, although without the completed sale’s price, size and date nobody can give a credible adjustment range here. The most useful next detail would be that full comparable, including whether it was genuinely similar in tenure and micro-location. If several large adjustments are needed, it may be too different to support a tight valuation at all.
 
For condition, I would create two scenarios rather than choose an arbitrary percentage: one covering cosmetic updating only, and another including any less visible work identified during inspection. Deduct the estimated work from the value of an otherwise comparable property, then test whether the result still makes sense against the listings. That gives you a range tied to the duplex rather than a generic condition grade.
 
Service charges and possible property tax costs should be shown separately from the capital value. They can affect what a buyer is willing to offer, but burying them inside a price-per-m² adjustment makes comparisons difficult. I would ask for the current amounts, what the service charge includes, and whether any unusual expenditure is expected, then let the local appraiser assess their significance.
 
My practical sequence would be: confirm the exact unit and micro-location; verify what the 195 m² includes; obtain lease, parking, outdoor-space and service-charge details; inspect and price the condition items; then rebuild the comparison around the single completed sale. Until that is done, KES 116,700,000 is an asking figure rather than a supported valuation. If the completed sale needs too many adjustments, ask the appraiser to widen the search rather than manufacture precision from it.
