Common Mistakes Nairobi Buyers Make When Comparing Apartments

The apartment comparison process in Nairobi produces a recognisable set of errors. They are not random mistakes made by careless buyers. They are systematic patterns that emerge from the same structural features of the Nairobi market: inconsistent information from agents, developer marketing that emphasises unit specification over building fundamentals, and a buying process that creates emotional momentum before due diligence is complete. Knowing the pattern in advance is the most practical way to avoid it.

Comparing on Price Per Square Metre Without Checking the Measurement Basis

Price per square metre is the comparison metric most buyers reach for first. It feels objective. It allows you to line up three or four developments in a spreadsheet and see which is cheapest per unit of space. The problem is that the square metre figures being compared are often calculated on different bases, and the difference between gross external area and net internal area on a typical Nairobi two-bedroom apartment is not trivial. It can be 12 to 18 percent of the stated figure.

A development in Kilimani quoting 95 sqm on a gross external basis may have 80 sqm of usable living space. A Kileleshwa development quoting 85 sqm on a net internal basis may have more functional room than the larger-sounding Kilimani unit. When buyers compare these two on price per stated square metre without adjusting for measurement convention, they draw a conclusion from numbers that do not represent the same thing.

Ask for floor plans with room dimensions rather than marketing illustrations with total area stated. Walk the space with a tape measure on the viewing. The bedroom that fits the furniture you plan to put in it is the usable bedroom, regardless of what the brochure says the floor area is.

Treating the Service Charge as a Secondary Consideration

Buyers in the comparison stage focus almost entirely on the purchase price and give the monthly service charge a fraction of the attention it deserves. The service charge is not optional, does not pause during vacancy, and continues for the life of your ownership. On a Ksh 15 million apartment with a Ksh 20,000 monthly service charge, the ownership cost over ten years includes Ksh 2.4 million in service charges alone before a single mortgage payment, utility bill, or maintenance cost is counted.

Two apartments at the same purchase price but with monthly service charges of Ksh 12,000 and Ksh 22,000 respectively represent a Ksh 120,000 annual difference in ownership cost. Over a five-year hold, that is Ksh 600,000. Over ten years it exceeds Ksh 1.2 million. This is not a rounding error. It is a material difference that should sit in every comparison, weighted appropriately against purchase price.

The comparison error compounds further when buyers take developer-estimated service charges at face value. Estimates for new and off-plan buildings in Nairobi have consistently run below the actual charge once the building is operational, for reasons that range from underestimating generator fuel costs at current prices to excluding sinking fund contributions from the headline figure. Apply a conservative buffer to any service charge estimate for a building that is not yet operational, and ask for the basis of the estimate rather than just the number.

Not Checking the Road Access Under Realistic Conditions

Nairobi's traffic reality is not captured by a map. Several residential streets in Kilimani, Kileleshwa, and Lavington that appear to be a short distance from main roads become significantly less accessible during morning and evening peak hours because they feed onto congested arterials with limited turning capacity. A building that takes eight minutes to reach from Ngong Road on a Saturday afternoon may take thirty-five minutes to exit during the 7.30am school run on a Tuesday.

Buyers who view properties at midday on a weekday or over the weekend are not seeing the road conditions that will define their daily commute experience. Some streets in Kilimani off Argwings Kodhek Road and parts of Kileleshwa near the James Gichuru Road junction are genuinely congested in ways that experienced residents have adapted to and visitors do not immediately appreciate. Drive the access route at the time of day that matches your actual commute pattern before you decide. This costs thirty minutes and prevents years of frustration.

For off-plan developments in locations that are being presented as emerging residential corridors, assess the road infrastructure as it currently exists, not as a render suggests it will look at completion. Infrastructure improvements in Nairobi follow their own timeline and are not guaranteed to coincide with a developer's projection.

Ignoring Building Occupancy as an Investment and Quality Signal

A building's current occupancy rate is one of the most useful single data points available to a Nairobi apartment buyer and it is one of the least frequently asked about. Occupancy tells you whether tenants and owner-occupiers who have already committed to the building and have no marketing incentive to portray it positively are choosing to stay or choosing to leave.

A building with 75 percent occupancy in a market where comparable buildings are running at 85 to 90 percent has an underlying problem. It may be management quality, water supply reliability, lift serviceability, a service charge that has risen faster than the rental market can absorb, or a physical defect in certain units that has created a reputation. All of these are discoverable with direct questions. None of them are visible in a brochure or on a developer's website.

Ask the agent for the current occupancy rate and ask what is driving any vacancy above 20 percent. Then speak to a current resident if you can arrange it. A two-minute conversation with someone who lives in the building and has no stake in you buying it is worth more than an hour of agent presentation.

Conflating the Developer's Brand With Due Diligence

Some Nairobi buyers bypass due diligence steps because they are buying from a developer with a recognisable name or a track record of completed projects. The reasoning is that a developer who has built and delivered multiple buildings is unlikely to have a title problem or a documentation gap on this one. This reasoning is not unreliable in the way that buying from an unknown developer without due diligence would be, but it is not a substitute for an Ardhisasa title search and a proper review of the sale agreement.

Even well-regarded developers in Nairobi have had title subdivision delays, have delivered buildings where the occupation certificate took longer than projected, and have included sale agreement clauses that place disproportionate risk on the buyer. The brand tells you something about the probability of a good outcome. It does not tell you anything about the specific transaction you are entering. Your advocate's review tells you that.

Buyers who sign sale agreements on the basis that the developer is reputable and the agreement is "standard" consistently find, when they eventually read the document carefully, that the completion date provisions, the penalty clauses, and the forfeiture terms were not what they had assumed. Read the agreement. Instruct your advocate to flag every clause that is unreasonably one-sided. This is what the advocate is for.

Falling for the Floor Level and View Premium Without Checking the Lift History

Upper-floor units in Nairobi apartment buildings command a premium based on views, natural light, reduced street noise, and the general preference buyers and tenants express for higher floors. This premium is real and generally justified in buildings where the lift infrastructure is reliable and well-maintained. It is not justified in buildings where lift reliability is inconsistent.

A fifteenth-floor apartment in a building where the lift breaks down for a week or more several times a year is a different product from the same unit in a building where lift maintenance is on a documented schedule and breakdowns are resolved within hours. Buyers who pay a floor premium without asking about the lift's service history and maintenance contract are paying for a view and accepting an infrastructure risk they have not priced.

Ask specifically: when was the lift last serviced, who is the maintenance contractor, and how long was the longest outage in the past two years? A building that cannot answer this question clearly is not managing its lift infrastructure with the seriousness that upper-floor residents require.

Comparing Finished Units With Bare-Shell Units on Purchase Price Alone

Bare-shell delivery is common across a significant proportion of Nairobi's new apartment stock, particularly at mid-range price points and across most off-plan developments. When buyers compare a bare-shell unit at Ksh 12 million against a finished resale unit at Ksh 14 million, the Ksh 2 million difference is not the full comparison. The bare-shell unit requires a fit-out investment that has typically ranged between Ksh 800,000 and Ksh 2 million for a two-bedroom apartment at a habitable standard, depending on specification. Add the time cost of managing a fit-out, the period of double-carrying costs if you are paying rent during construction, and the Ksh 2 million price premium on the finished unit begins to look different.

Neither option is automatically better. But the comparison needs to be total cost to occupancy, not headline purchase price. Buyers who make the comparison on headline price alone and then discover the fit-out cost after committing to the bare-shell unit are routinely surprised by a cost that was entirely predictable from the point of sale.
