How METRIKA calculates this
METRIKA simulates both paths month by month:
- Buyer pays the deposit and buying costs, then the mortgage (reducing balance) plus ownership costs. Net worth = home value − selling costs − mortgage balance + any savings invested in months when owning cost less than rent.
- Renter invests the same upfront cash and, in months when owning would cost more than rent, invests the difference. Rent rises once a year.
Both portfolios earn the same return, so the comparison is fair. Taxes on investment returns (15% withholding on interest) and mortgage interest relief are not modelled.
What to know in Kenya
Kenyan home ownership decisions often weigh land or a family plot against renting in town. Stamp duty is 4% of value in municipalities and 2% elsewhere. The Kenya Mortgage Refinance Company supports single-digit-rate mortgages for qualifying affordable homes through partner banks and SACCOs; if you qualify, try a lower mortgage rate here.
Frequently asked questions
Is it better to rent or buy in Nairobi?
It depends on the price-to-rent ratio, your mortgage rate and how long you'll stay. Where yearly rent is a small share of the price, renting and investing often wins over 5–10 years.
What is a breakeven year?
The first year when the buyer's net worth passes the renter's. If you plan to move before then, renting is usually the better financial choice.
Why include selling costs?
Your home only turns into cash after agent, legal and transfer costs. Leaving them out makes buying look better than it is.
