What sellers need to know
Selling a property in Kenya sets off two separate obligations: agreeing on a price with a buyer, and settling what the taxman is owed on the difference between that price and what the property cost you. The second obligation is Capital Gains Tax, and it is due before the transfer can even be registered. A seller who has not planned for it can find the sale stalled at the finish line.
What Capital Gains Tax actually taxes
Capital Gains Tax, or CGT, is charged on the profit made when property, land or unquoted shares change hands in Kenya, and it is administered under the framework that the Kenya Revenue Authority sets out for CGT. It is a tax on the gain, not on the sale price; if a property is sold at a loss, no CGT arises. The seller, referred to as the transferor, carries the obligation to declare and pay it, not the buyer.
The current rate
CGT in Kenya is charged at 15% of the net gain on a property transfer. It is a final tax, meaning once it is paid, that gain is not taxed again elsewhere. The net gain is the transfer value, less incidental costs of the transfer, less the adjusted cost of the property, being acquisition cost, incidental acquisition costs, and any enhancement or improvement costs.
A worked example
Take a seller who bought a plot in 2019 and is transferring it now. The numbers below show how the net gain and the tax on it are actually arrived at.

Net gain |
KES 3,650,000 |

KES 547,500 |
What counts as a deductible cost
The gain is calculated after allowable expenses are subtracted, so keeping records of these from the day of purchase pays off at the point of sale:
When a sale is exempt
Not every transfer attracts CGT. The exemption sellers ask about most often is the private residence exemption: a property is exempt if the owner has occupied it continuously for the three years immediately before the transfer. Other exemptions cover transfers between spouses, transfers to immediate family, transfers as part of a divorce settlement, and transfers by a personal representative to a beneficiary in the course of administering a deceased person’s estate.
How and when it gets paid
CGT is declared and paid through iTax, and it falls due at whichever comes first: the seller receiving the full purchase price, or the transfer instrument being registered in the buyer’s favour. In practice, this means the tax is settled as part of closing, not afterward, and a completed transfer is not registered until it is.
Why this matters before a sale is priced
Sellers who treat CGT as a closing-day formality often discover the acquisition cost and improvement record they need are incomplete. Establishing the adjusted cost base early and confirming whether an exemption applies changes what a sale actually nets, and it changes it before an asking price is set rather than after an offer is accepted.
Stamp duty is the single largest one-off cost a buyer pays on top of the purchase price itself, and it is also the one most first-time buyers underestimate. It isn’t hidden; it’s a matter of public record, but it rarely appears on the price tag shown during a viewing, which is exactly why it catches so many buyers scrambling for extra cash right at the point of transfer.
What Stamp Duty Actually Is
Stamp duty is a tax charged on the legal instrument that transfers property from seller to buyer, collected by the Kenya Revenue Authority under Section 2 of the Stamp Duty Act, Cap 480. It isn’t optional, and it isn’t negotiable between buyer and seller; it’s a statutory charge, and the transfer document itself has no legal force until it’s paid.
How Much It Actually Costs- and a 2024 Change Worth Knowing
The standard rate is 4 percent of the property’s value for land classified as urban, and 2 percent for land classified as rural or agricultural. Where this gets less straightforward is that the boundary between “urban” and rural” has shifted: a directive from the Principal Secretary for Lands in April 2024 formally reclassified a long list of gazetted towns and municipalities, including areas in Kiambu, Ruiru, and Thika previously treated as rural, to the 4 percent urban rate. A buyer who assumes a peri-urban plot still qualifies for the lower rural rate, based on how the area was classified a few years ago, can end up budgeting for half of what they actually owe. Confirming current classification with the relevant land registry, rather than assuming based on how a location “feels”, is worth doing before finalizing a budget.
What the Rate Is Actually Calculated On
Stamp duty is not calculated on the price in the sale agreement. It is calculated on the property’s determined market value, which is why the process always involves a government valuation step before the final figure is known. If the government valuer’s assessed figure comes in higher than the agreed purchase price, stamp duty is charged on the higher figure, not the lower one a buyer negotiated. This is a common source of budgeting surprise: a buyer who negotiates a good price on paper can still owe stamp duty calculated against a materially higher official valuation.
The valuation itself isn’t something a buyer commissions privately and submits. It’s carried out, or verified, by the Chief Government Valuer or a valuer they’ve designated, specifically to establish the property’s true open market value for stamp duty purposes, separately from any valuation a bank might have ordered for mortgage approval, and separately from whatever figure a selling agent quoted during marketing. A buyer relying on a bank’s mortgage valuation or an agent’s asking price as a stand-in for the government figure can end up with a materially wrong budget, since these three numbers frequently diverge.
Stamp Duty Isn’t the Only Closing - Just the Biggest One
It’s easy to treat stamp duty as the whole story of what a transfer costs beyond the purchase price, but it’s really the largest line item in a longer list. Legal fees for the conveyancing advocate, land registry and registration charges, the cost of the government valuation itself, and in some cases survey fees all sit alongside stamp duty as separate, additional costs. None of these are optional extras a buyer can skip by using a different process; a property transfer in Kenya legally requires a licensed advocate to prepare and register the documents, so budgeting for stamp duty in isolation, without the costs that travel alongside it, still leaves a buyer short at completion.
Who Pays It, and When
The buyer pays. This is standard practice in Kenyan property transactions, and it isn’t something a sale agreement typically reassigns. Once the transfer instrument is assessed, payment is due within 30 days of assessment for locally prepared instruments, or within 30 days of receipt for documents executed abroad. That window is shorter than it sounds once conveyancing, valuation scheduling, and fund transfers are factored in, which is exactly why the money needs to be set aside before the transaction reaches this stage, not scrambled for once the assessment lands.
What Happens If You Don’t Pay
This isn’t a fee a buyer can quietly skip or defer indefinitely. An unstamped transfer instrument is legally invalid, and any agreement signed between the parties becomes null and void and is inadmissible in court as evidence until the duty is paid. Missing the payment window doesn’t just delay the paperwork; it attracts a penalty of 5 percent of the assessed duty for every quarter it remains unpaid, which compounds quickly on a six- or seven-figure transaction. The property simply cannot be legally registered in the buyer’s name without this step being completed.
How to Actually Pay It
Payment is made through KRA’s iTax platform rather than at a bank counter or land registry desk. A buyer or their advocate logs into iTax, registers the payment under the Agency Revenue tax head with Stamp Duty as the sub-head, fills in the transfer and valuation details, and generates a payment slip that can be settled via bank transfer or M-Pesa. This is generally handled by the conveyancing advocate as part of the transfer process rather than something a buyer does entirely alone, but knowing the mechanics helps a buyer follow along and confirm the payment has actually cleared before assuming the transfer is complete.
The Exemptions, and Why Most Buyers Won’t Qualify
A handful of exemptions exist, but they’re narrower than buyers sometimes assume. The recognized categories are transfers of property between spouses, transfers of family property to surviving members on the death of the person in whose name it was registered, and gifts of land to registered charitable organizations. There is no general first-time buyer exemption in Kenya’s standard property market; a first apartment purchase through an ordinary sale agreement attracts stamp duty at the full standard rate, the same as any other buyer. Exemptions also aren’t automatic even where a buyer genuinely qualifies; they require an application and approval before payment, not a claim made after the fact.
How to Budget for It, Concretely
· Estimate on the higher end: use the government valuation as your working assumption, not the price you negotiated, since the two can diverge
· Confirm the classification of the specified location before assuming the rural rate applies, particularly in fast-growing peri-urban areas in Nairobi
In Summary
Stamp duty isn’t a fee that can be negotiated away or quietly avoided; it’s a statutory cost that determines whether a property transfer is even legally valid. Budgeting for 4 percent of a property’s likely government valuation, rather than 4 percent of the negotiated price, confirming the area’s current classification before assuming a rate, and setting stamp duty within the wider basket of closing costs rather than treating it as the only add-on are the adjustments that keep this cost from becoming a last-minute scramble.
Most apartment buyers never deal with the National Construction Authority directly. No sale agreement asks them to sign anything on the NCA’s behalf, and no viewing includes a stop at a regulator’s office. Yet almost everything that determines whether a building was actually built the way it was supposed to be traces back, at some point, to this one authority. Knowing what it does, what it doesn’t, and how to check its records turns it from an acronym on a signboard into a genuinely useful tool for evaluating a development before committing to it.
What the NCA Is and What It Regulates
The National Construction Authority is the statutory body established to regulate and streamline Kenya’s construction industry, with its core registration powers anchored in law: a person may not carry on the business of a contractor in Kenya unless registered by the Authority’s Board and holding a valid practicing license, under Section 15 of the National Construction Authority Act. In practice, this means the Authority sits upstream of almost every construction project in the country, residential, commercial, or public, licensing the contractors who build them, setting the standard they must build to, and inspecting sites to check that those standards are being met while work is underway.
The Authority also funds much of this regulatory work through a construction levy written into the same Act: a levy of up to 0.5 percent of contract value applies to construction projects worth more than five million shillings, with the proceeds directed toward the Authority’s inspection, training, and enforcement activities. For a buyer, the detail worth knowing is simply that a development of any meaningful size sits inside a system with its own dedicated funding for compliance checking, which is a large part of why registration status and inspection records are worth asking about rather than assuming.
Why Every Contractor Needs NCA Registration, and What the Categories Mean
Registration is not a formality a contractor can skip for a smaller job. It is the legal precondition for operating at all, and it comes with a category system that matters more to a buyer than it might first appear.
Contractors are classified from NCA1 down to NCA8 according to their technical capacity, financial strength, and track record, with each category capped at a maximum contract value they are permitted to handle. At the top, an NCA1 building contractor faces no upper limit on contract value, while an NCA8 contractor is capped at roughly KSH 10 million, according to the value-limit schedule published on the government’s official investment procedures portal. The categories in between scale down accordingly, and the classification applies separately across building works, specialist works, and roads and civil works, so a contractor’s strength on one class does not automatically carry over to another. The system exists precisely so that a contractor’s registered capacity can be checked against the scale of the project they are building, which means a multi-storey apartment block being handled by a contractor registered for small-scale work only is not a technicality. It is a direct signal that the project may be outside that contractor’s demonstrated capability.
What Happens When a Developer Skips Registration
Working without valid NCA registration is not a grey area under the Act; it is a legal condition for operating as a contractor at all, which means an unregistered contractor is already outside the law before the first wall goes up. In practice, this exposes a project to real consequences: a site can be marked non-compliant and issued a notice of suspension of works, halting construction until the issue is resolved; the contractor risks losing eligibility for future government and large private contracts, since NCA registration is a standard prerequisite for tendering; and the project owner, not just the contractor, carries the practical fallout of delays, rework, or disputes that follow from work that was never properly licensed or inspected in the first place. None of that is compensation a buyer can easily recover after the fact, which is exactly why it is worth checking before a deposit changes hands rather than after.
What NCA Site Inspections Actually Check
Registration is the entry condition; inspection is how the Authority checks that a specific project keeps meeting it once construction is underway. Project owners are required to register their projects with the Authority and maintain compliance throughout construction, with site visits carried out under the National Construction Authority Regulations of 2014 to verify that a site is being run to standard. A compliant site is issued a site compliance certificate; a non-compliant one can be marked for suspension of works until the issues are corrected. For a buyer, this is the mechanism that theoretically stands between “the developer says the site is compliant” and an independent regulator actually having checked.
A buyer purchasing a completed unit can at least walk through it before signing. An off-plan buyer is paying against a set of drawings and construction timeline, with no finished product to inspect until well after money has changed hands. For that buyer, NCA registration status and site compliance records are not a nice-to-have; they are close to the only independent, checkable signal available during the months or years when the building is still just a hole in the ground and a set of renders. Asking for a contractor’s NCA category and a project’s compliance status before paying a deposit is, in effect, the off-plan buyer’s version of a site visit.
The National Building Code: The Floor Beneath Every Specification
Beyond registering contractors and inspecting sites, the Authority also sets the technical standard against which everything is measured. Kenya’s construction sector now operates under the National Building Code 2024, which came into full legal effect on 1 March 2025, replacing building regulations in place since 1968. Whatever a developer specifies in a sale agreement- finishes, structural design, fire safety provisions, it cannot legally fall below what this code requires. That gives a buyer a fixed, checkable reference point, rather than having to take a developer’s word for what “industry standard” means.
From NCA Compliance to Occupation Certificate: The Paper Trail Behind a “Ready” Unit
The NCA is one link in a longer chain of approvals a building has to pass through before anyone can legally move in. After NCA project registration and site compliance are in order, the county government still has to issue its own occupation certificate, the document that legally confirms a completed building was constructed to the approved plans and is safe for occupation, following a final multi-departmental inspection. That final inspection typically checks structural integrity, fire safety installations, sanitation systems, and electrical work against the approved drawings; in other words, a second, independent look at many of the same fundamentals the NCA has already been monitoring during construction. Occupying or letting a unit without that certificate is not a paperwork gap a buyer can safely ignore; it can complicate insurance claims, utility connections, and the property’s own resale down the line. An NCA compliance record and a county occupation certificate are two different documents from two different authorities, and a buyer is entitled to ask for both.
How to Actually Use This as a Buyer
In Summary
The National Construction Authority will never be the reason a buyer falls in love with a unit, but it is one of the few checks in the process that exists independently of the developer’s own marketing. A registered contractor working within their actual capacity, a site that has passed compliance inspection, and a building that holds a proper occupation certificate are not guarantees that nothing will ever go wrong; but they are the difference between a claim a buyer has to take on faith and one they can actually verify. The paperwork exists precisely so a buyer does not have to rely on trust alone, and asking for it costs nothing but a conversation most developers should be entirely comfortable having.
What sellers need to know
Selling a property in Kenya sets off two separate obligations: agreeing on a price with a buyer, and settling what the taxman is owed on the difference between that price and what the property cost you. The second obligation is Capital Gains Tax, and it is due before the transfer can even be registered. A seller who has not planned for it can find the sale stalled at the finish line.
What Capital Gains Tax actually taxes
Capital Gains Tax, or CGT, is charged on the profit made when property, land or unquoted shares change hands in Kenya, and it is administered under the framework that the Kenya Revenue Authority sets out for CGT. It is a tax on the gain, not on the sale price; if a property is sold at a loss, no CGT arises. The seller, referred to as the transferor, carries the obligation to declare and pay it, not the buyer.

In Summary
The National Construction Authority will never be the reason a buyer falls in love with a unit, but it is one of the few checks in the process that exists independently of the developer’s own marketing. A registered contractor working within their actual capacity, a site that has passed compliance inspection, and a building that holds a proper occupation certificate are not guarantees that nothing will ever go wrong; but they are the difference between a claim a buyer has to take on faith and one they can actually verify. The paperwork exists precisely so a buyer does not have to rely on trust alone, and asking for it costs nothing but a conversation most developers should be entirely comfortable having.
An apartment price on a listing is a single figure. What that figure covers is a list, one that varies from developer to developer, and sometimes from unit to unit within the same block. A first-time buyer who assumes the quoted price includes everything shown in a marketing render is the buyer most likely to be surprised at handover, not because anyone lied, but because nobody confirmed the list in writing before signing.
Why “Apartment Price” Isn’t a Single Number
Two units in the same development, at the same price point, can come with different specifications depending on when they were sold and what package the buyer negotiated. Some developers quote a base finish as standard, with kitchen upgrades, wardrobe finishes, or air conditioning offered as paid extras. Others build a higher specification into the base price and market it as such. Neither approach is wrong, but a buyer comparing two units purely on price, without checking what each figure includes, is not comparing like with like.
The same gap shows up in how pricing is structured internally. Some developers sell on a lump-sum basis, where one figure covers a fixed specification and any changes the buyer requests are priced as variations. Others price certain categories- sanitaryware, wardrobes, kitchen cabinetry- as allowances within the total, meaning the final specification is only pinned down once the buyer chooses within that allowance. Neither structure is inherently better, but a buyer who does not know which one they are dealing with cannot tell whether the number they were quoted is a ceiling, a starting point, or an estimate that assumes the cheapest option in every category.
What Counts as a Finish, and What Counts as a Fitting
The two terms get used loosely, but the distinction matters when reading a sale agreement. A finish is a fixed surface treatment applied to the structure itself: wall paint, floor tiling, ceiling treatment, and the grouting and painting that go with them. A fitting is a fixed item installed into the unit: sanitaryware, kitchen units, wardrobes, doors, ironmongery, electrical fittings, and the water heater. Furniture and appliances that are not fixed to the structure: a fridge, a cooker, a washing machine, normally sit outside both categories and outside the purchase price entirely, unless the agreement states otherwise. A buyer should know which of the three categories every item they care about falls into, because only two of them are usually assumed to be included.
Within “finishes” specifically, it helps to separate the structural layer from the visible layer. Floor screed, for example, is a structural finish that is rarely specified in detail because it is not visible; floor tiling is a visible finish that should be specified by the type, size, and quality grade. The same applies to doors: an internal flush door and a solid-core security door are both “doors” in a brochure description, but they are not interchangeable in cost or quality, and a specification that simply says “doors as required” gives a buyer no way to know which one they are getting.
The Legal Anchor: The Schedule of Specifications
Kenyan sale agreements for off-plan or newly built units are expected to carry a schedule of specifications, a document listing the exact materials, finishes, and fittings the developer commits to installing. A properly drafted agreement should set out detailed specifications of finishes, materials, and fittings to prevent discrepancies between what was promised and what is delivered, rather than leaving the buyer to rely on marketing brochures or a show unit that may not reflect the final product. Without that schedule attached as part of the contract, a buyer has comparatively little to point to if the delivered unit falls short of what was shown at the point of sale.
The schedule also needs to survive construction intact. A developer’s ability to change the design, layout, or finishes after signing should be tightly limited, since material variations that substantially affect the value, size, appearance, or functionality of the property should trigger clear buyer rights rather than being left to the developer’s discretion. A specification clause that allows unrestricted substitution is, in practice, no specification at all.
Where Price Ambiguity Creeps In
Even a detailed specification schedule can leave room for dispute if a few common gaps are not closed:
How to Read a Specification Schedule
A specification schedule is only useful if it is enough to check against the finished unit. A well-written line item names four things: the brand or manufacturer, the model or product code, the grade or finish level, and where in the unit it applies. “Porcelain floor tiles, 600×600mm, matte finish, living and dining areas” tells a buyer exactly what to expect and exactly what to compare against on inspection day. “Quality floor tiles throughout” tells them nothing enforceable. When reviewing a schedule, a buyer should treat any line item that could describe five different products equally well as a line item that needs to be pinned down before signing, not after.
The Quality Floor Behind the Specification
Whatever is specified still has to meet a regulatory minimum. Kenya’s construction sector now operates under the National Building Code 2024, which came into full legal effect on 1 March 2025, replacing building regulations that dated back to 1968. The code sets a national floor for construction quality that no specification schedule can legally fall below, which gives a buyer a baseline to check a developer’s stated specification against, rather than relying solely on the developer’s own marketing language.
Material authenticity is a separate but related concern. Counterfeit electrical fittings are among the goods regularly recovered in enforcement raids, according to the Anti-Counterfeit Authority, which is one more reason a specification naming an actual brand and model is worth more than one describing an item generically. A generic description gives a contractor room to install whatever is cheapest and available, genuine or not.
What Belongs to the Unit, and What’s Shared
Not everything a buyer sees in a development’s marketing sits inside the purchase price of a single unit. Kenyan law separates a sectional development into individually owned units and common property owned by all unit proprietors as tenants in common under the Sectional Properties Act. Gym equipment, lobby finishes, landscaping, and lift fittings typically fall under common property, maintained through the service charge, not funded through any single buyer’s purchase price. A buyer should ask, item by item, whether an amenity shown in the brochure is inside their unit, or is common property they will contribute toward maintaining after handover.
What to Confirm Before You Sign
In Summary
The price on a listing is a starting point for a conversation, not a complete answer. What turns that number into an enforceable promise is a specification schedule that names the actual materials, fittings, and finishes a buyer is paying for, attached to the sale agreement rather than implied by a brochure. Confirming that list before signing costs a buyer nothing but a conversation. Discovering the gaps after the handover costs considerably more.
Buying a home too early is one of the most expensive mistakes a first-time buyer can make in Kenya, not because homeownership is a bad goal, but because the financial and legal machinery around it punishes borrowers who go in underprepared. This isn’t a sales pitch to convince you to buy now; it’s a self-assessment to help you honestly answer a harder question: are you actually ready? Work through the sections below before you start touring show houses.
Financial Readiness: The Numbers That Actually Matter
Kenyan banks typically cap total mortgage repayments at 40% to 50% of a borrower’s net monthly income, meaning your new home loan instalment, combined with any existing debts, should not exceed that share of your take-home pay. If you haven’t calculated this number for yourself yet, thus us the first and most important test: a property you can’t comfortably finance under this rule isn’t ready for you yet, regardless of how much you want it.
Beyond the mortgage itself, budget realistically for the deposit and the transaction costs that follow. A standard down payment in Kenya sits around 20% of the property value, and total closing costs- stamp duty at 4% for urban land or 2% for rural land, legal fees, valuation, and registration charges- typically add up to a further 6% to 11% of the property’s value on top of the purchase price. On a KSh 5 million property, that’s roughly KSh 1 million in deposit plus KSh 300,000 to 550,000 in closing costs, money that needs to be available in cash, separate from the mortgage itself.
Credit Readiness: What Your CRB Status Says About You
A default listing with a Credit Reference Bureau in Kenya is retained in the CRB database for five years from the last date of payment. This is worth knowing well before you apply for a mortgage: even after you’ve fully settled a defaulted loan, the record of that default can still be visible to lenders for years, and it will factor into how they assess your application.
A CRB clearance certificate confirms your current credit status as at the date it’s issued, but it does not erase or hide your credit history; lenders will still see your past payment record regardless of whether you hold a clearance certificate. If you’ve had credit issues in the past, request your own credit report now, well before you plan to apply, so there are no surprises when a bank pulls it during underwriting.
Job and Income Stability: How Long Is Long Enough
Salaried employees on permanent contracts, particularly those on an employer check-off arrangement, are typically viewed most favourably by lenders and may access preferential mortgage pricing, while self-employed applicants usually face closer scrutiny of income consistency and may need a larger deposit. If you’re newly self-employed, or you’ve just switched jobs, it’s worth building a track record before applying rather than after; lenders are assessing consistency, not just your current income figure.
Emergency Fund:
No lender will ask whether you have savings set aside beyond your deposit, but you should ask yourself. A mortgage is a decades-long commitment, and job changes, medical costs, and general life disruptions happen. Before buying, most financially prudent borrowers aim to hold three to six months of essential living expenses in accessible savings, separate from the deposit and closing costs earmarked for the purchase itself. This buffer is what stands between a temporary setback and a missed mortgage payment.
Time Horizon: Are You Actually a Five-Year Buyer?
The break-even period, the holding time required before transaction costs are recovered through capital appreciation and, where relevant, rental income, is typically three to five years for a property bought in a good location at a fair price. If your job, relationship, or life plans could realistically move you elsewhere within two or three years, that’s a legitimate reason to rent for now and revisit buying once your situation is more settled; the transaction costs alone make short-term ownership expensive.
A Simple Self-Assessment Checklist
☐ I have calculated my own debt-to-income ratio, and it sits comfortably under my bank’s 40 – 50% ceiling, including the new mortgage instalment.
☐ I have saved (or have a clear plan to save) roughly 20% of the property value as a deposit, separate from closing costs.
☐ I have budgeted an additional 6– 11% of the property value in cash for stamp duty, legal fees, valuation and registration.
☐ I have requested my own CRB report and know exactly where I stand, with no unresolved negative listings.
☐ I have at least two to three years of stable, verifiable income, as an employee or, if self-employed, as a documented income history.
☐ I hold three to six months of living expenses in savings, separate from my deposit and closing costs.
☐ I realistically expect to stay in this property, or this city, for at least five years.
Checking every box doesn’t guarantee a smooth purchase, but missing several is a strong signal to pause and address the gaps first, not necessarily to abandon the goal.
What “Not Ready Yet” Actually Looks Like, and What to Do About It
The AYA Real Estate View
Readiness to buy isn’t a single number; it’s the combination of your income, your credit history, your savings discipline, and how long you genuinely intend to stay put. A first-time buyer who takes an honest inventory of all five before house-hunting tends to have a far smoother, faster transaction than one who starts with the property and works backward. AYA Real Estate is happy to talk through where you stand across Westlands, Kilimani and Vipingo, whether that means helping you buy now or helping you build toward being ready.
