Plot and Construction Mortgage in Kenya: How to Buy Land and Build a Home
Want to build your own home but do not yet own the land? You may not need separate loans for the plot purchase and construction.
A plot and construction mortgage can finance the purchase of qualifying land together with the cost of building a residential home on it. Instead of receiving all the construction money at once, the funds are released in stages as the building progresses.
This guide explains how plot and construction financing works, how much cash you may need, the documents involved and the issues to consider before applying.
What is a plot and construction mortgage?
A plot and construction mortgage is a home loan that combines two related expenses:
Purchasing a plot of land.
Constructing a residential home on that land.
The land purchase is generally assessed using the lower of the agreed purchase price or the bank’s open-market valuation. The construction amount is based on the approved cost of building, usually shown in a priced bill of quantities.
The KCB Plot & Construction Mortgage is intended for customers purchasing land of up to two acres and constructing a residential unit within six months of acquiring the plot.
Subject to valuation, affordability and credit approval, KCB can finance up to 90% of the eligible land and construction cost.
Which property loan fits your plans?
The correct facility depends on whether you already own the land and how soon you intend to build.
You want to buy land and build soon: A Plot & Construction Mortgage may finance both under one facility.
You already own the land: A Residential Construction Mortgage may be more appropriate because you only need construction financing.
You want to buy land but build later: Consider a KCB Plot Loan.
You want to purchase a completed home: Explore the KCB Home Loan.
This distinction is important because the deposit, documentation, valuation and disbursement process can differ across the facilities.
How does a plot and construction mortgage work in Kenya?
The process normally moves from budgeting and land due diligence to mortgage approval, land purchase and staged construction.
1. Estimate the complete project cost
Start with more than the advertised plot price and basic construction estimate.
Your budget should account for:
The land purchase.
Architectural and engineering services.
A quantity surveyor and priced bill of quantities.
County and regulatory approvals.
Construction labour and materials.
Legal, valuation and registration costs.
Insurance.
Utility connections and site preparation.
Interior finishes.
A contingency for unexpected expenses.
This helps you determine whether your income and available cash can support the complete project before you commit to buying land.
2. Identify and investigate the plot
Confirm the ownership and legal status of the land before paying a deposit.
An official search can help confirm the registered owner and disclose registered interests affecting the title. Land-search services are available through the government’s Ardhisasa platform.
You should also confirm:
Whether the land is suitable for residential development.
Whether it has practical and legal access.
Whether the intended development is permitted.
Whether water, electricity and other services are available.
Whether the property can obtain the necessary county and regulatory approvals.
Use an independent advocate and qualified property professionals rather than relying only on information supplied by the seller or agent.
3. Prepare the plans and construction budget
Work with qualified professionals to prepare:
Architectural plans.
Structural drawings.
A detailed and priced bill of quantities.
A realistic construction programme.
County and other applicable project approvals.
A formal agreement with the contractor.
The bill of quantities is particularly important because it sets out the materials, work and expected cost at each stage. It also helps the lender assess whether the requested construction amount is realistic.
4. Submit the mortgage application
The bank will assess:
Your income and existing financial commitments.
Your credit and repayment history.
The proposed property.
The land valuation.
The construction budget.
The project plans and approvals.
Your ability to complete and repay the facility.
Approval is not based on the plot price alone. The lender must be satisfied that the entire project is properly planned, affordable and capable of being completed.
5. Complete the land purchase
Once the facility is approved and the required legal and security documents are completed, the land-purchase portion can be paid to the appropriate beneficiary under the conditions in the letter of offer.
Read the offer carefully before accepting it. It should explain your contribution, fees, interest, repayment obligations and the conditions for releasing construction funds.
6. Draw construction funds in stages
The construction portion is not normally released as one lump sum.
KCB releases the construction funds in a maximum of four instalments linked to progress on the site. Before the next instalment is released, the bank may require an inspection or confirmation that the previous stage has been completed satisfactorily.
Your contractor’s payment schedule should therefore align with the mortgage drawdowns. A contractor who expects payment before a construction stage is verified could create a cash-flow gap.
7. Service the facility during construction
KCB states that applicants service interest during construction and for a further two months afterwards.
Your letter of offer should confirm:
How interest is calculated during construction.
When payments begin.
How construction drawdowns affect the amount payable.
When the facility moves into full mortgage repayment.
Do not assume that you will make no payments until the house is complete.
How much can KCB finance?
KCB states that its Plot & Construction Mortgage can finance up to 90% of the eligible total cost.
The calculation is based on:
The lower of the plot’s purchase price or open-market valuation.
The accepted construction cost in the priced bill of quantities.
Your demonstrated ability to repay.
This means you should generally expect to contribute at least 10%, although your actual cash requirement may be higher.
For example, suppose:
The agreed plot price is KES 4 million.
The plot is valued at KES 3.6 million.
The accepted construction cost is KES 6 million.
The eligible project base may be calculated using KES 3.6 million for the land plus KES 6 million for construction, giving KES 9.6 million.
At a maximum of 90%, the illustrative financing would be KES 8.64 million. You would need to cover the difference between the financing and the actual project cost, plus the applicable fees and other expenses.
This is only an illustration. The amount approved will depend on the valuation, project, affordability and credit assessment.
KCB also requires the applicant’s contribution to be used upfront. Keep a separate contingency fund rather than assuming that your deposit can also cover unexpected construction expenses.
What other costs should you budget for?
In addition to your contribution, allow for:
Valuation and legal fees.
Stamp duty and registration expenses.
Architectural, engineering and quantity-surveying services.
County and regulatory approvals.
Mortgage and construction-related insurance.
Site preparation and utility connections.
Contractor supervision.
Material price increases.
Unexpected construction work.
Ask for a written breakdown of the applicable costs before accepting the mortgage.
You can also use the KCB Mortgage Calculator to estimate repayments, total interest and the potential cost of credit. Calculator results are illustrative and do not constitute approval.
What documents are needed?
The exact requirements depend on the applicant and project, but you should prepare documents in three main areas.
Personal and income documents
These may include:
National ID or passport.
KRA PIN.
Recent payslips and employer confirmation.
Bank statements.
Business registration and financial records for self-employed applicants.
Evidence of other regular and verifiable income.
Land documents
These may include:
A valid sale agreement or offer letter.
A copy of the title.
An official land search.
A valuation report.
Spousal consent or a sworn affidavit, where applicable.
For leasehold property, KCB currently requires the title to have at least 35 years remaining.
Construction documents
These may include:
Approved architectural plans.
Approved structural drawings.
A signed and priced bill of quantities.
Evidence of the contractor’s NCA registration.
Current licences and profiles for the project professionals.
A formal construction contract.
Applicable environmental and county approvals.
Required insurance documents.
A performance bond where required.
KCB may request additional documents depending on the size and complexity of the project.
Who can apply?
KCB lists the following among the customers it may consider:
Employed Kenyans.
Self-employed Kenyans.
Kenyans living in the diaspora.
Employed and self-employed non-Kenyan residents.
Companies and partnerships.
Investment groups.
The property offered as security must be in Kenya.
Regular and verifiable income may come from employment, a business, rent, commissions, pensions or qualifying group contributions.
Being included in one of these categories does not guarantee approval. The amount and terms will depend on affordability, documentation, valuation and the bank’s credit assessment.
Is a plot and construction mortgage right for you?
This facility may suit you if:
You do not yet own the land.
You want to purchase a qualifying plot and build soon afterwards.
You have approved or workable plans for a residential home.
You can provide your contribution and cover the related costs.
Your income can support interest during construction and later repayments.
You are prepared to coordinate contractors, professionals, approvals and inspections.
It may not be the right option if you only want to buy land, already own the plot or want to purchase a completed home.
If you are still deciding whether to rent or become a homeowner, read the guide to renting versus buying property in Nairobi.
Common mistakes to avoid
Before starting the project:
Do not purchase land before completing legal due diligence.
Do not budget only for the plot and basic structure.
Do not use unregistered contractors or unlicensed professionals.
Do not agree to contractor-payment dates that conflict with mortgage drawdowns.
Do not make major changes to approved plans without the necessary approval.
Do not commit your entire cash reserve to the deposit.
Do not assume the facility will automatically increase if costs rise.
Good planning protects the construction timeline and your ability to repay.
Frequently asked questions
Can I get one mortgage to buy land and build a house in Kenya?
Yes. A plot and construction mortgage can finance both the purchase of qualifying land and the construction of a residential home.
The lender will assess the land, proposed building, construction budget, approved plans and your ability to repay before deciding how much to finance.
What is the difference between a Plot Loan and a Plot & Construction Mortgage?
A Plot Loan finances the purchase of land without necessarily financing immediate construction.
A Plot & Construction Mortgage combines the purchase of qualifying land with financing for a planned residential build. KCB requires customers using this facility to construct within the period specified for the product.
How much deposit do I need?
KCB can finance up to 90% of the eligible plot and construction cost, subject to valuation, affordability and approval. This suggests a contribution of at least 10%.
Your total upfront requirement may be higher because of valuation differences, professional fees, legal expenses, stamp duty, insurance and costs not included in the approved facility.
How are construction mortgage funds released?
Construction mortgage funds are normally released in stages called drawdowns.
Each drawdown is linked to progress on the approved development. Before releasing the next payment, the lender may inspect the site or request confirmation that the previous stage has been completed.
KCB releases the construction portion in a maximum of four instalments.
Do I start repaying before the house is complete?
You may need to make interest or interim payments while construction is underway.
KCB requires applicants to service interest during construction and for a further two months. Your letter of offer should explain when full mortgage instalments begin and how payments are calculated.
Can I apply if I already own the land?
Yes, but a construction-only mortgage may be more appropriate because you do not need financing for the plot purchase.
Ask KCB whether its Residential Construction Mortgage is more suitable for your project.
Can self-employed applicants qualify?
Yes. Self-employed applicants can be considered if they demonstrate regular, verifiable income and the ability to repay.
The bank may assess business bank statements, financial records, existing debts and the stability of the business.
Can Kenyans living abroad apply?
Yes. KCB lists Kenyans living in the diaspora among the customers who may apply.
Applicants will normally need to provide identity, income, banking and property documents. It is also important to appoint reputable professionals who can supervise the construction and document progress in Kenya.
How long can I take to repay the mortgage?
KCB states that the maximum repayment period for its Plot & Construction Mortgage is 25 years.
Your approved term may be shorter depending on your age, affordability, property and the bank’s assessment. A longer term can reduce the monthly repayment but usually increases the total interest paid.
What happens if construction costs exceed the approved budget?
The mortgage does not automatically increase when construction costs rise. You may need to cover the additional amount yourself or ask the lender to assess whether further financing is possible.
Reduce this risk by using a detailed bill of quantities, agreeing on written contractor prices and keeping a realistic contingency fund.
Is building a house cheaper than buying a completed one?
Not always. Building gives you more control over the design and materials, but professional fees, approvals, delays and cost overruns can increase the final cost.
Buying a completed home usually provides greater price certainty and allows you to occupy the property sooner. Compare the complete cost of both options before deciding.
