Kenyan mortgages in 2026: rates, deposits and what banks actually approve

Kenyan mortgage rates have spent recent years in a band most buyers find uncomfortable — roughly 10.5% to 16.5% depending on lender, product and buyer profile — because banks price home loans off their cost of funds and the policy rate, not off wishful thinking. Understanding the mechanics changes how you should shop: the sticker rate matters, but the structure of the offer (deposit, term, fees, insurance bundling) often moves your total cost more than half a point of headline rate.

The 33% rule that prices your ceiling

Kenyan banks, following CBK consumer-protection guidance, generally cap the mortgage instalment near a third of your verifiable net income, after subtracting existing obligations. That single ratio converts your salary into a maximum property price faster than any brochure. Run it: net income KES 400,000 with KES 50,000 of other obligations leaves about KES 82,000 for an instalment; at 13.5% over 15 years with 20% down, that supports roughly a KES 7.5M principal — call it a KES 9.4M property. Keja’s calculator has a dedicated Affordability mode that does this math with your numbers.

What banks actually scrutinise

• Verified income: 6–12 months of bank statements and, for the employed, an introduction letter; for the self-employed, two to three years of accounts
• Existing obligations: existing loans cut your ceiling shilling-for-shilling of instalment
• The property itself: a bank valuation protects the bank, and gently protects you from overpaying
• Track record: a clean CRB record is table stakes; clear disputes before you apply, not after
• Citizenship and tenure: leasehold terms and land-control rules can shape which products apply

The lever most buyers ignore: the extra payment

At 13.5%, interest dominates the early years of a 15-year loan. One structured extra payment a year — or a rounding-up of the instalment — attacks principal directly and compounds quietly. On a KES 8M, 15-year loan, adding KES 15,000 to every instalment can clear the loan around three years early and save seven figures in interest.
