You earn well. You’ve saved a big deposit. You’ve found the perfect home. Then one small mortgage mistake quietly costs you Ksh 48M–Ksh 180M over the life of the loan.
Here are the 10 mortgage mistakes Kenya luxury buyers make in 2026 — and the simple fixes that save fortunes.
1. Choosing the Lowest Advertised Rate Without Reading the Fine Print
Bank advertises “from 11.2 %”. You celebrate. Then you discover that rate is only for civil servants or loans under Ksh 50M. Your Ksh 450M luxury mortgage actually starts at 14.8 %.
Fix: Always ask: “What is the actual rate for my exact profile and loan size?”
2. Not Getting Written Pre-Approval Before House Hunting
You find your dream home, make an offer, pay deposit. Bank then approves only 60 % of what you need. You lose the deposit and the deposit.
Fix: Get a written pre-approval letter stating the exact loan amount before you start viewing.
3. Using Your Regular Bank Because “They Know Me”
Your salary account is with Bank A. You assume they’ll give you the best deal. Bank B (that you’ve never used) offers 2.8 % lower rate and 90 % LTV.
Fix: Shop at least 4 banks. Loyalty rarely pays in luxury mortgages.
4. Forgetting the Bank Only Finances 70–80 % on Luxury Homes
You qualify for Ksh 500M total. You forget luxury properties are capped at 70–80 % LTV. You need Ksh 100M–Ksh 150M cash you don’t have.
Fix: Ask every bank: “What percentage will you finance on a Ksh 600M property?”
5. Accepting a 30-Year Term Without Crunching the Numbers
Longer term = lower monthly payment = feels good. But on Ksh 400M at 13 %:
- 20 years = Ksh 4.68M/month, total interest Ksh 722M
- 30 years = Ksh 4.42M/month, total interest Ksh 1.19B You just paid an extra Ksh 468M for Ksh 260K “savings” per month.
Fix: Run 15-year vs 20-year vs 25-year scenarios before signing.
6. Not Locking Your Rate (and Watching It Jump Before Closing)
You’re quoted 12.4 %. Six months later when you’re ready to draw down, rates are 14.9 %. Extra cost on Ksh 500M loan: Ksh 98M over the term.
Fix: Ask for a 180-day rate lock (most banks offer it on luxury loans).
7. Ignoring the Total Cost of Credit (Not Just the Interest Rate)
Bank A: 12.5 % rate, but Ksh 22M in fees Bank B: 13.1 % rate, but Ksh 4M in fees Bank B is actually cheaper by Ksh 68M over 20 years.
Fix: Always compare “Total Amount Payable” not just the headline rate.
8. Not Stress-Testing Your Income for Rate Rises
2026 rates are 12–14 %. If they hit 18 % in 2028 (possible), your Ksh 5M payment becomes Ksh 7.2M. Many buyers can’t afford that jump.
Fix: Make sure you can still pay if rates rise 4–5 %.
9. Signing Without an Independent Advocate Review
Bank sends you a 42-page mortgage document. You sign because “it’s standard”. Hidden clause: 8 % penalty for early repayment. You want to clear the loan in 10 years → Ksh 128M penalty.
Fix: Your own advocate reviews every line before you sign.
10. Not Planning for the End Game
You take a 25-year mortgage at age 48. You’ll still be paying at 73. Many buyers discover too late they can’t retire because of the loan.
Fix: Choose a term that ends before (or at) your planned retirement age.
