A data-backed guide for Kenyan homebuyers, diaspora investors, and first-time landlords evaluating apartment size in Westlands, Kilimani, Parklands, and Nairobi’s satellite towns.
Unit size is usually the first decision a buyer makes and the last one they think carefully about. Most conversations start with location, then budget, then design finishes. However, in Nairobi’s apartment market, the choice between a studio, a 1-bedroom, and a 2-bedroom unit is doing more work than any of those factors; it sets the rent a unit can command, the type of tenant it attracts, how quickly it re-lets when vacant, and how easily it resells five or ten years from now.
This matters more today than it did five years ago. Nairobi’s household structure has shifted, apartment supply has concentrated in a handful of well-defined nodes, and financing costs are moving in a direction that changes what different buyers can comfortably afford. The right unit size is no longer a matter of personal taste alone; it is a calculation, and one worth making deliberately.
Why Unit Size Is a Structural Decision, Not a Cosmetic One
According to the 2019 Kenya Population and Housing Census, Nairobi County has the smallest average household size in the country at 2.9 persons, against a national average of 3.9. That single statistic explains much of what is happening in the city’s apartment market: demand has been shifting toward compact, efficient units built for singles, couples, and small households, even as some buyers continue to plan around the larger family home they associate with homeownership.
This creates two separate markets operating under one roof. A studio or 1-bedroom unit in Kilimani is competing for tenants against short-term rentals, serviced apartments, and shared housing. A 2-bedroom or larger unit is competing against standalone rentals in Lavington, Karen, or the satellite towns. Understanding which market a unit belongs to is the starting point for choosing between them.
What Each Configuration Actually Offers
The Studio
A studio combines living, sleeping, and kitchen space into a single open room, typically with a separate bathroom. Across AYA’s Kilimani and Kileleshwa market report, studios run from roughly 40 to 46 square metres, smaller studio formats do exist elsewhere in the city, but this is the band most common in these two nodes. Studios carry the lowest entry price of the three configurations, and because they need less furniture, less maintenance, and shorter turnaround between tenants, they are often the fastest unit type to lease or re-lease.
The 1-Bedroom
A 1-bedroom unit separates the sleeping area into its own room, usually adding a proper lounge and a more defined kitchen. This is Nairobi’s most liquid apartment category, it is what most young professionals search for first, and it is the configuration developers build in the highest volumes across Westlands, Kilimani, and Parklands. Depth of demand tends to make 1-bedroom units easier to both let and resell than either studios or larger units.
The 2-Bedroom
A 2-bedroom unit adds a second bedroom, generally a second bathroom, and enough space for a small family, a couple with a home office, or two working professionals sharing costs. It commands the highest absolute rent sale price of the three, and it tends to attract tenants who stay longer, corporate leases, small families, and long-term professional tenants who value stability over frequent moves.

Inside AYA’s Listings: Kilimani vs Kileleshwa by Unit Type
Averages across all of Nairobi’s upper-mid suburbs can obscure real differences between individual nodes just a few kilometres apart. A review of AYA’s active Kilimani and Kileleshwa listings shows that, by unit type, Kilimani currently commands a meaningful yield premium over its neighbour.

The gap is consistent across both configurations: Kilimani 1-bedrooms outyield Kileleshwa 1-bedrooms by roughly a full percentage point, and the same pattern holds for 2-bedrooms. Kileleshwa units are typically larger and more expensive for the same bedroom count, which lowers the yield even where they are comparable or higher in absolute terms. For an investor weighing the two side by side, Kilimani currently offers the stronger income return, while Kileleshwa’s larger typical unit sizes and quieter, more residential character continue to appeal to buyers prioritizing space and long-term livability over headline yield.
Buying to Live In: Matching Space to Life Stage
For owner-occupiers, the decision is more personal but still benefits from discipline. A single professional or a couple without children is often better served by a 1-bedroom than a 2-bedroom bought “just in case”; the unused room adds cost and service charge without adding quality of life in the near term. A small family, on the other hand, gains real value from the second bedroom, both for daily living and for the option to work from home.
A useful test: buy for the household you have now and the one you expect in the next three to five years, not the one you might have in ten. Nairobi’s active and rental markets mean that moving up in size later, once income or family circumstances change, is a realistic path, particularly for units in well-established, liquid nodes.
Buying to Let: Yield, Vacancy, and Tenant Demand by Unit Type
For investors, the calculation shifts from comfort to return. Across AYA’s Kilimani and Kileleshwa listings, 1-bedroom units post the highest median yield of the three configurations at 10%, ahead of studios at 9.1% and 2-bedrooms at 8.0%. The pattern holds direction-wise across both nodes: smaller units generate a higher percentage return on capital, even though they command a lower absolute rent.
Yield, however, is only half the picture. Larger units, 2-bedrooms and above, tend to attract family and long-term corporate tenants who churn less often than the single-professional and short-stay tenants who dominate the smaller-unit market. A high headline yield on a studio or 1-bedroom is only useful if the unit is actually occupied; a slightly lower yield on a 2-bedroom with consistently low vacancy can outperform it over a full year.
The practical implication: studios and 1-bedrooms suit investors who are comfortable managing more frequent tenant turnover in exchange for a higher percentage return, while 2-bedroom units suit investors who prioritise predictable, lower-maintenance income over a higher headline number.
Financing Each Option: What Current Rates Mean for You
Financing conditions affect unit-size decisions more directly than most buyers realise. The Central 5Bank of Kenya held its benchmark rate at 8.75% in April 2026, after 10 consecutive cuts since August 2024, and this has gradually pulled down commercial mortgage pricing from its recent peaks, though most bank mortgage rates in 2026 still sit in the 12% - 10% range.
Buyers targeting studios and 1-bedroom units in the affordable price bands have an additional lever: mortgages for properties valued up to KES 10.5 million can qualify for Kenya Mortgage Refinance Company (KMRC)-backed financing, with rates typically several percentage points below standard commercial terms. This is because studios and many 1-bedroom units in satellite towns and even some Nairobi nodes fall within this threshold; KMRC-backed financing can materially change the monthly repayment math in favor of smaller units, a factor worth checking before ruling out a configuration on price alone.
Two-bedroom units in prime nodes more often exceed the KMRC threshold and are financed through standard commercial mortgages, Sacco products, or developer instalment plans, which remain the dominant route to ownership for most Kenyan buyers regardless of unit size.
Location Changes the Calculus
Unit-size economics do not transfer cleanly from one neighborhood to another. In Westlands, strong demand from corporate, diplomatic, and expatriate tenants supports premium rents across all three configurations, with studios and 1-bedrooms often achieving the highest percentage yields due to serviced and short-stay demand. In Kilimani, a dense concentration of young professionals and a well-established short-let market keep 1-bedroom and studio vacancy low, while 2-bedroom units draw steady demand from shared-occupancy professionals and small families.
Parklands offers a comparatively more affordable entry point with a growing base of family-oriented 2- and 3-bedroom stock, while satellite towns such as Ruaka, Syokimau, and Kahawa West have recorded some of the city’s fastest-improving yields, driven by infrastructure gains and more accessible entry prices, a dynamic that tends to favor 1- and 2-bedroom units bought by first-time owner-occupiers and value-focused investors.
Exit Liquidity: Which Unit Type Resells Fastest
Resale speed deserves as much attention as rental yield, particularly for buyers who may need to exit within five to ten years. In most Nairobi nodes, 1-bedroom units are the most liquid resale category; they suit the widest pool of both owner-occupier and investor buyers, which shortens time on market. Studios have a narrower resale pool, concentrated among first-time buyers and investors, so pricing discipline at the point of purchase matters more. Well-located 2-bedroom units in nodes with strong school and family infrastructure tend to hold value well over the long term, even if they take marginally longer to sell than a comparably priced 1-bedroom.
A Simple Framework for Deciding
Where AYA Real Estate Fits In
The right unit size is rarely obvious from a floor plan alone. It depends on the node, the building's tenant profile, the financing route available to a specific buyer, and what that buyer is actually optimizing for: comfort, yield, liquidity, or all three in different proportions. AYA Real Estate works through this calculation with individual investors, diaspora buyers, and first-time homeowners across Westlands, Kilimani, Parklands, and Nairobi's satellite towns, using current market data rather than general assumptions to match buyers to the unit type that fits their goals.
Whether the objective is a first home, a first rental investment, or an addition to an existing portfolio, the unit-size decision is worth the same rigor applied to location and financing. Get it right, and the rest of the investment tends to follow.
