Mortgage vs cash in Kenya: the real cost in KES

Kenyan mortgage rates are high by global standards and most buyers who can pay cash do. That is not always the right call. The honest comparison is not "interest versus no interest"; it is the total cost of borrowing against what your cash would earn elsewhere, after tax, over the same period. Here is that comparison on a real-sized purchase.

The worked example

A KES 10 million apartment. Buyer puts down 20 percent, so the loan is KES 8 million over 20 years.

At a typical commercial bank rate of 13 percent (rates track the Central Bank Rate plus a bank-specific premium and have moved between 12 and 17 percent in recent years):

• Monthly repayment: about KES 93,700
• Total repaid over 20 years: about KES 22.5 million
• Total interest: about KES 14.5 million

At a KMRC-backed affordable rate of 9.5 percent, available through participating banks and saccos for owner-occupied homes under a price cap (currently around KES 10.5 million in the Nairobi metropolitan area, lower elsewhere; the Kenya Mortgage Refinance Company publishes the current thresholds):

• Monthly repayment: about KES 74,600
• Total repaid: about KES 17.9 million
• Total interest: about KES 9.9 million

The rate difference alone is worth KES 4.6 million over the life of the loan. If you qualify for KMRC-refinanced lending, that is the first thing to secure.

The fees on top of interest

Mortgage costs in Kenya are front-loaded. On the KES 8 million loan above, expect roughly:

• Arrangement or processing fee: 1 to 2 percent of the loan, KES 80,000 to 160,000.
• Valuation: KES 20,000 to 40,000, payable to the bank's panel valuer whether or not the loan proceeds.
• Bank's legal fees: the borrower pays the bank's advocate to prepare the charge, in addition to their own conveyancing advocate. Budget under the Advocates Remuneration Order, typically KES 80,000 to 150,000 combined at this loan size.
• Stamp duty on the charge: 0.1 percent of the loan amount, KES 8,000, on top of the 4 percent stamp duty on the purchase itself, which you pay either way.
• Insurance: the bank will require fire and perils cover on the property and a mortgage protection policy on your life, with the bank named as first loss payee. Together, budget 0.5 to 0.8 percent of the loan each year, KES 40,000 to 64,000.

Add roughly KES 250,000 to 400,000 in year one before a single repayment.

What offsets the cost

Mortgage interest relief. Owner-occupiers can deduct mortgage interest from taxable income up to a statutory cap, currently KES 360,000 a year. For a borrower in the 30 percent band that is worth up to KES 108,000 a year, which knocks about a point off the effective rate in the early years when most of your repayment is interest.

The home ownership savings and affordable housing routes. Contributions and levy-linked schemes come with their own rules; check with KRA and your employer what applies to you rather than assuming.

Inflation. A fixed KES 93,700 repayment gets lighter in real terms every year. Rents in the same building will not.

When cash is the more expensive option

Cash is not free. It has an opportunity cost equal to whatever you would otherwise have earned with it, and in Kenya that number has been unusually high. Government securities have paid double-digit returns for much of the last few years, and infrastructure bonds are tax-exempt. The Central Bank of Kenya publishes auction results weekly.

If your KES 10 million could earn 12 percent tax-free in a bond while a KMRC mortgage costs 9.5 percent before tax relief, borrowing and investing the difference is cheaper than paying cash, even after the fees above. When bond yields fall below your mortgage rate, the calculation flips.

The second case for borrowing is diversification. A buyer who puts every shilling into one apartment holds one illiquid asset in one neighbourhood. A buyer with a mortgage and a bond portfolio can survive an eighteen-month vacancy.

When cash wins

• You are buying at auction or from a distressed seller, where a cash offer closes in weeks and wins a discount that exceeds any financing arbitrage.
• The property is leasehold with a short remaining term, or the title is under conversion, and no bank will lend on it at a sensible rate.
• You are over 55 and lenders will cap the term, pushing repayments beyond your income.
• You would otherwise hold the cash in a savings account earning less than inflation.

Compare the mortgage rate after tax relief against the after-tax return on the best alternative you would actually buy. If the mortgage is cheaper, borrow. If it is not, pay cash and keep your borrowing capacity for the next deal.
