A KSh 8,000,000 home with 10% down at 13.0% over 20 years costs KSh 84,353 a month, plus KSh 1,260,000 upfront.
The cash you need before you get the keys
Most Kenyan lenders finance 80–90% of a property’s value, so you need a 10–20% deposit. On top of that come stamp duty (4% within a municipality, 2% outside), legal fees of roughly 1–1.5% for the transfer and the charge, and a valuation fee. First-time buyers of affordable housing can be exempt from stamp duty.
Mortgage interest relief
Interest paid on a loan to buy or build your own home is deductible from taxable income, up to KSh 360,000 a year (KSh 30,000 a month). Ask your lender to give your employer the annual interest certificate so the relief reaches your payslip.
