The most common rule of thumb used by Kenyan banks and mortgage providers is that your monthly mortgage payment should not exceed 30–40% of your gross monthly income. However, what you can truly afford depends on your full financial picture — existing debts, family obligations, savings available for deposit, and job security.
The Affordability Rules Explained
28%
Housing Cost Rule
Your mortgage payment alone should not exceed 28% of your gross monthly income. This is the most conservative guideline, favoured by housing finance bodies.
36%
Total Debt Rule
All monthly debt payments combined (mortgage + car loan + credit cards) should not exceed 36% of gross income. This is the "36/28 rule" used by many lenders.
40%
Kenya Bank Maximum
Most Kenyan commercial banks and SACCOs will approve a mortgage if total debt service does not exceed 40% of net (take-home) income. This is the outer limit.
Average House Prices in Kenya by Location (2024)
Understanding typical prices helps you calibrate your expectations. In Nairobi, a standard 3-bedroom apartment in a middle-class area like South B or Embakasi costs KSh 6–10M, while the same property in Kilimani or Lavington may cost KSh 14–25M. In satellite towns like Ruaka or Syokimau, you can find quality 3-bedroom maisonettes for KSh 8–14M.
What Salary Do You Need to Buy a House in Kenya?
Using the 30% rule and current mortgage rates of approximately 13% on a 20-year term: to afford a KSh 5M property (after a 20% deposit of KSh 1M), you need a monthly repayment of approximately KSh 37,000, which requires a gross income of at least KSh 123,000/month. For a KSh 10M property, you'd need approximately KSh 246,000/month gross income.
Affordability FAQs
Your questions about buying a home in Kenya, answered
What salary do I need to buy a house in Nairobi?
For an entry-level apartment in Nairobi (KSh 4–6M), you typically need a gross monthly salary of at least KSh 80,000–120,000 with a 20% deposit saved. For a 3-bedroom in a mid-range area (KSh 8–12M), you'd need KSh 150,000–250,000/month gross. Use our calculator above for a personalised estimate based on your specific situation.
Can I get a mortgage with a KSh 50,000 salary in Kenya?
Yes, but your options will be limited. At KSh 50,000 gross, lenders will typically approve a monthly payment of KSh 15,000–20,000, which corresponds to a loan of approximately KSh 1.2–1.6M on a 20-year term at 13% interest. Combined with savings for a deposit, this could access properties in the KSh 1.5–2.5M range — mainly bedsitters or 1-bedroom units in satellite towns. A SACCO or co-operative housing loan may offer better terms.
How much deposit do I need to buy a house in Kenya?
Most Kenyan banks require a minimum deposit of 10–20% of the property value. SACCOs may require 10–20% or equivalent in member shares. So for a KSh 6M property, you'd need KSh 600,000–1.2M as a deposit. You'll also need additional funds for stamp duty (2–4% of property value), legal fees (1–1.5%), valuation fees, and mortgage insurance.
What are all the costs when buying a house in Kenya?
Beyond the purchase price, budget for: Stamp Duty (2% for properties under KSh 5M, 4% for higher), legal/conveyancing fees (1–1.5%), valuation fee (0.25–0.5%), bank/mortgage arrangement fees (1–2%), property insurance, and moving costs. Total transaction costs typically add up to 6–10% of the purchase price.
Does this calculator account for taxes?
Yes, our calculator estimates PAYE tax using Kenya's current income tax bands (as at 2024) to arrive at your net take-home pay. The tax estimate is approximate — for a precise figure based on all deductions (NHIF, NSSF, etc.), consult with a financial advisor or use the KRA iTax portal.
