When buyers start searching for apartments in Nairobi, they quickly encounter two very different markets operating side by side. On one side are brand new developments, many of them off-plan, with polished show units, developer payment plans, and the appeal of being the first person to occupy a space. On the other side are older apartments resold by existing owners, often in established buildings in mature neighbourhoods, sometimes at lower prices but with a different set of considerations.
The question of whether to buy new or old is one that every apartment buyer in Kenya eventually has to answer, and the answer is not the same for every buyer. It depends on your budget, your purpose — whether you are buying to live in or to invest — your risk tolerance, your timeline, and the specific characteristics of the properties you are comparing. A blanket preference for new over old, or old over new, misses the nuance that distinguishes a genuinely good purchase from a mediocre one.
This guide compares new and old apartments in Kenya across every dimension that matters to a buyer: construction quality, legal standing, pricing dynamics, investment returns, maintenance liability, and suitability for different buyer profiles. It works alongside our articles on signs of poor construction in apartments and how to evaluate property value before purchasing, and connects to the full buying process in our complete guide to buying property in Kenya.
Defining New and Old in the Kenyan Context
In Kenya’s apartment market, the distinction between new and old is not simply a matter of age. It reflects differences in design standards, construction technology, legal framework, and market positioning that cut across multiple dimensions simultaneously.
For this guide, a new apartment refers to a unit in a development that is either currently under construction, recently completed within the past three years, or being offered directly by a developer on a primary sale basis. This includes off-plan purchases where the buyer commits before or during construction.
An old apartment refers to a unit in a building that has been in occupation for more than three years, typically sold by an existing owner on a secondary market basis. In Nairobi, this category includes a wide range of building vintages, from apartments constructed in the 1970s and 1980s in areas like Upper Hill and Kilimani, to 1990s and early 2000s stock in Westlands and Kileleshwa, to buildings from the first wave of the Nairobi apartment construction boom between 2005 and 2015.
Construction Quality: New vs Old
New Apartments
New apartments benefit from being constructed under the current regulatory framework, including the Physical and Land Use Planning Act 2019 and the current edition of the Kenya Bureau of Standards building construction standards. Newer buildings are also required to comply with the National Construction Authority’s registration and supervision requirements under the NCA Act 2011, which mandates that construction be carried out by registered contractors under professional supervision.
In theory, this means newer apartments should be built to a higher and more consistently enforced standard than older ones. In practice, the quality of new construction in Kenya varies enormously depending on the developer, the contractor, the level of professional supervision, and the budget allocated to construction. As documented in the NCA’s Annual Reports, building quality complaints from buyers of new developments are among the most consistently reported categories, suggesting that regulatory compliance alone does not guarantee construction quality.
New apartments also benefit from modern design approaches. Buildings constructed after approximately 2015 increasingly incorporate features that older Nairobi buildings lack, including adequate backup power with generators sized for full building load, borehole water supply with roof storage, modern fibre-ready telecommunications infrastructure, improved natural ventilation design, and lifts that meet current standards. According to the Kenya Green Building Society, newer residential developments in Nairobi are increasingly incorporating green building principles including rainwater harvesting, solar water heating, and energy-efficient lighting, which reduce long-term running costs for occupants.
The risk with new apartments, particularly off-plan purchases, is that the construction quality you see in the show unit or the developer’s brochure may not reflect what is delivered in your actual unit. Show units are invariably finished to a higher standard than production units in the same development, and the gap between the two can be significant. Our article on signs of poor construction in apartments details the specific defects that are common in new Nairobi apartment developments and how to identify them.
Old Apartments
Older apartments carry the advantage of a track record. A building that has been in occupation for ten or fifteen years has already revealed its construction quality — or lack of it — through the problems that have manifested over time. A buyer of an older apartment can inspect the actual unit rather than a show unit, speak to existing residents about their experience of living in the building, review the management corporation’s maintenance records, and form a view of the building’s real condition rather than a developer’s marketed version of it.
However, older buildings in Nairobi present specific risks that new buildings do not. Many apartments built before 2010 were constructed before the Sectional Properties Act 2020 came into force, under the older Sectional Properties Act 1987 which had weaker provisions for title clarity and management corporation governance. Some older developments have title complications that have not been resolved, or have management corporations that are dysfunctional or non-existent, leaving common area maintenance in a chronic state of neglect.
Buildings from the 1970s, 1980s, and 1990s were constructed to the design standards of those periods, which are materially lower than current standards in areas such as structural load capacity, fire safety, electrical safety, and thermal performance. Galvanised steel water supply pipework, which corrodes internally and contaminates the water supply over time, was standard in Nairobi apartment construction until the early 2000s and is still present in many older buildings. Old rewirable fuse boards without residual current device protection are a safety risk that the Kenya Power and Lighting Company has consistently flagged in its consumer safety guidance.
According to research published by the University of Nairobi’s Department of Urban and Regional Planning, a significant proportion of Nairobi’s pre-2000 apartment stock requires major capital expenditure on essential systems including plumbing, electrical installations, roofing, and lift replacement, expenditure that falls on the management corporation and therefore on all unit owners through increased service charges.
Legal Considerations: New vs Old
New Apartments
For new off-plan developments, the primary legal risk is the stage of title registration at the time of purchase. Under the Sectional Properties Act 2020, a developer is required to file a sectional plan at the Lands Registry before selling individual units. However, as the Law Society of Kenya has documented in its conveyancing practice notes, some developers in Kenya have historically sold units before completing the required sectional plan registration, leaving buyers with contractual rights but not yet with registered titles.
A buyer who purchases an off-plan unit and pays in full but does not yet have a registered sectional title is exposed to risk if the developer encounters financial difficulties, becomes insolvent, or defaults on the construction. The buyer’s recourse in such a situation is primarily contractual — against the developer under the sale agreement — rather than through registered title rights, which are stronger.
Your advocate must confirm that the developer has either already filed the sectional plan or has contractually committed to doing so within a specified period as a condition of the sale agreement. The risk profile of a new development where the sectional plan is already registered is materially lower than one where registration is still pending.
For buyers considering new developments, our article on due diligence before buying property in Kenya covers the specific title checks relevant to new and off-plan purchases in detail.
Old Apartments
Older apartments in the secondary market carry their own set of legal considerations. Title searches may reveal encumbrances from the current owner’s mortgage, which must be discharged before transfer. In some older buildings, the management corporation has not been properly constituted, and the governance of common areas is informal or contested. Some older buildings constructed under the 1987 Sectional Properties Act have title registration complications that require specialist legal work to resolve before a clean transfer can be achieved.
The advantage of older apartments from a legal perspective is that the title exists and is registered. There is an actual title document to search against, a registered proprietor whose identity can be confirmed, and a property with a transaction history that your advocate can review. The legal unknowns with an older apartment are generally more limited than with an off-plan new development where the title may not yet exist in its final form.
Pricing Dynamics: New vs Old
New Apartments
Developer pricing for new apartments in Nairobi typically incorporates a new-build premium reflecting the perceived advantage of a never-occupied unit and the developer’s marketing and sales costs. According to HassConsult’s Nairobi Property Price Indices, new developments in Kilimani and Westlands have historically been priced at a premium of between 10% and 25% above comparable resale apartments in the same neighbourhoods, though this premium narrows significantly for developments that have been on the market for more than 18 months.
For off-plan purchases, developers typically offer staged payment plans tied to construction milestones, which can make a higher-priced unit financially accessible to buyers who cannot pay the full price upfront. This is a genuine financial advantage that older apartment purchases — which typically require full payment at completion — do not offer. The Kenya Bankers Association has noted that developer payment plans have been a significant driver of apartment uptake among middle-income buyers in Nairobi, particularly for purchases financed through a combination of personal savings and partial mortgage financing.
The risk of paying a new-build premium is that you are paying for freshness that depreciates rapidly in the first few years of occupancy. An apartment that commands a 20% premium as a new unit may trade closer to its old-apartment equivalent within three to five years once that new-build premium dissipates.
Old Apartments
Older apartments in Nairobi’s secondary market are often available at lower prices per square metre than equivalent new developments, reflecting the absence of a new-build premium, the potential maintenance liability of the building, and in some cases motivated sellers who need to liquidate quickly. This price differential can represent genuine value for buyers who are willing to assess the condition of the building carefully and factor maintenance costs into their acquisition calculation.
For investment buyers, an older apartment purchased below the replacement cost of a new comparable unit can deliver strong rental yields and capital appreciation over time, particularly in locations where land values are rising and the density of new supply is constrained. According to Cytonn Real Estate’s Kenya Residential Property Report, well-located older apartments in Kilimani, Lavington, and Kileleshwa that are maintained to a reasonable standard have delivered capital appreciation broadly comparable to new developments in the same areas over five to ten-year holding periods, despite the initial price discount.
Investment Returns: New vs Old
Rental Yield
Rental yield — the annual rental income as a percentage of the purchase price — is generally higher for older apartments than for new ones in comparable locations, for the simple reason that the purchase price is lower. An older 2-bedroom apartment in Kilimani purchased at Ksh 8 million that achieves Ksh 55,000 per month in rent delivers a gross yield of 8.25% per annum. A new 2-bedroom apartment in the same area purchased at Ksh 12 million achieving the same rent delivers a gross yield of 5.5% per annum.
This yield advantage of older apartments over new ones in the same location is well-documented in the Kenyan market. According to the Knight Frank Kenya Property Report, gross rental yields for resale apartments in established Nairobi neighbourhoods have consistently outperformed yields on new-build apartments in the same areas, reflecting the purchase price gap between the two categories.
For investment buyers whose primary objective is income return, older apartments in well-maintained buildings in high-demand rental locations deserve serious consideration alongside new developments.
Capital Appreciation
New apartments have historically delivered stronger capital appreciation in the short to medium term in Nairobi, particularly for off-plan purchases made during the construction period when the developer’s price has not yet adjusted to reflect the completed building’s market value. Buyers who purchase off-plan at an early construction stage discount and sell upon or shortly after completion can capture this appreciation as a capital gain.
Over longer holding periods of ten years or more, the capital appreciation differential between new and old apartments in comparable locations tends to narrow significantly, according to HassConsult’s long-run property price data for Nairobi. Land value appreciation — which affects all properties in a location regardless of building age — eventually dominates building-specific factors in determining long-term total return.
Maintenance Liability: New vs Old
This is one of the areas where the distinction between new and old apartments is most practically significant for buyers.
A new apartment in a well-constructed building has essentially zero deferred maintenance liability at the point of purchase. The building’s major systems — roof, lifts, plumbing, electrical — are new and under their respective manufacturer warranties. The management corporation’s service charge budget should be modest in the early years of the building’s life.
An older apartment in a building that has not been well maintained carries a potentially significant deferred maintenance liability. Major items such as roof replacement, lift overhaul, external repainting, and plumbing system upgrades have defined lifespans, and in a poorly managed building these works get deferred year after year until they become urgent. When they eventually become unavoidable, the cost falls on all unit owners through a special levy over and above the regular service charge.
According to the Affordable Housing Board of Kenya, special levy calls in older Nairobi apartment buildings have ranged from Ksh 50,000 to Ksh 500,000 per unit for major capital works such as roof replacement or full lift overhaul, representing a significant unexpected cost for unit owners who did not budget for it. Before purchasing an older apartment, buyers should request a copy of the management corporation’s maintenance schedule and sinking fund balance to understand whether funds are being set aside for future major works or whether the building is running a maintenance deficit.
Suitability for Different Buyer Profiles
First-Time Owner-Occupier Buyers
For buyers purchasing their primary residence for the first time, a new apartment offers the emotional satisfaction of moving into a never-occupied home and the practical convenience of a unit with modern specifications and no immediate maintenance concerns. If a developer payment plan is available, it can also ease the financial burden of the purchase by spreading payments over the construction period.
The risks — construction quality variance, off-plan title delays, and the new-build premium — are manageable with proper due diligence and advocate oversight. For a first-time buyer who prioritises certainty of condition and modern amenities, a new apartment from a reputable developer in an established neighbourhood is often the right choice.
Investment Buyers
For buyers primarily motivated by rental yield and investment return, the mathematics often favour older apartments, particularly those available below replacement cost in high-demand rental areas. The yield advantage, combined with lower entry price and the ability to negotiate more aggressively on price, can produce stronger income returns than new developments in the same locations.
Investment buyers should focus on the rental market characteristics of the specific location, the condition and management quality of the building, and the scope for value enhancement through refurbishment of the individual unit, as discussed in our article on how to evaluate property value before purchasing.
Diaspora and International Buyers
For Kenyan diaspora buyers or international investors purchasing remotely, new developments from established developers offer cleaner processes, more standardised documentation, and dedicated buyer support that simplifies remote purchasing. The risk of buying an older apartment remotely without the ability to physically inspect is higher, as the condition assessment that is critical for older buildings is harder to conduct from a distance.
Our platform’s listings for homes for sale in Nairobi Kenya and 2-bedroom apartments for sale in Nairobi feature both new developments and resale properties, with detailed specifications that help remote buyers compare options across both categories. For buyers specifically interested in Westlands, our 2-bedroom apartments for sale in Westlands listings cover current options across both new and existing stock in that neighbourhood, and our 3-bedroom apartments for sale in Kileleshwa page gives a comparable picture for Kileleshwa.
Making the Decision: A Framework
Rather than recommending new or old as a universal answer, the right framework for making this decision involves asking five specific questions about any apartment you are seriously considering.
The first is the condition question: what is the physical condition of the specific building and unit, and what maintenance liability am I acquiring? This applies to both new and old apartments — a new apartment in a poorly constructed building carries more risk than an old apartment in a well-maintained one.
The second is the title question: is the title clean, registered, and free from encumbrances, and for new apartments, has the sectional plan been filed? This is the legal dimension that your advocate addresses through the due diligence process.
The third is the value question: is the price I am being asked to pay supported by comparable market evidence, and am I paying a premium I can justify? For new apartments, the new-build premium should be evaluated against the specific advantages it provides in the specific building. For old apartments, the discount should be evaluated against the maintenance and upgrade liability it implies.
The fourth is the return question: what rental income will this property generate relative to the price I am paying, and is that return consistent with my investment objectives? The yield calculation described earlier in this article gives you a direct answer.
The fifth is the management question: is the building under competent, financially sound management, and is the service charge adequate for the maintenance obligations of the building? This question is most urgent for older buildings but applies to new developments as well, where the management corporation is newly established and its effectiveness is not yet proven.
Conclusion
New and old apartments in Kenya each have a coherent case in their favour, and neither is universally superior to the other. The right answer depends on the specific property, the specific buyer, and the specific purpose of the purchase.
What is clear is that the new versus old question cannot be answered by marketing materials, asking prices, or assumptions about which category is inherently better. It must be answered by the evidence: a physical inspection, a professional valuation, a thorough title search, a review of building management records, and an honest assessment of how the numbers stack up against your objectives.
Buyers who do that work — who move beyond the surface appeal of a newly painted apartment or the price attraction of an older one — make decisions grounded in reality rather than impression. In Kenya’s property market, that discipline is the difference between a purchase that builds wealth and one that drains it.
