Cheap or Expensive? How Your Mortgage Choice Could Cost You Million

The cost of financing a home is becoming as important as the purchase price for Kenyan buyers, with mortgage terms increasingly determining whether home ownership remains affordable over the long term.

As residential property prices continue to rise, housing finance experts say buyers should look beyond the listed price of a property and consider the full cost of borrowing. Differences in mortgage pricing between lenders can add millions of shillings to the total amount repaid over the life of a loan.

The latest Residential Property Price Index by the Kenya National Bureau of Statistics (KNBS) shows residential property prices increased by 4.8 percent in the first quarter of 2026 compared with the same period in 2025. Prices also rose by 0.6 per cent from the previous quarter, reflecting continued demand for apartments, maisonettes and detached houses despite economic pressures.

The cost of buying a home illustrates the challenge facing many households. A two-bedroom apartment in Nairobi typically costs about Sh6 million, while similar family homes in growing satellite towns including Syokimau, Kitengela and Ruiru generally sell for between Sh8 million and Sh12 million. However, the purchase price is only one part of the overall cost, as the mortgage chosen largely determines the total amount repaid.

Housing finance specialists say borrowers buying similar properties can face very different repayment costs because mortgage terms vary across lenders. Interest rates, funding costs, borrower risk assessments and repayment periods all influence the final cost of a home loan. As a result, households with similar incomes may receive different mortgage offers.

According to Johnstone Oltetia, Chief Executive Officer and Managing Director of the Kenya Mortgage Refinance Company (KMRC), the high cost of mortgages has largely been linked to the way financial institutions fund long-term housing loans.

"Mortgages are long-term loans, but many financial institutions rely on short-term customer deposits to fund them. That mismatch raises the cost of lending and ultimately makes home ownership unaffordable for many Kenyans," he says.

KMRC was established to address this challenge by providing banks and deposit-taking savings and credit co-operatives (saccos) with long-term funding at lower cost. This allows participating lenders to offer mortgages with longer repayment periods and fixed single-digit interest rates for up to 25 years.

Fixed-rate mortgages provide borrowers with certainty over their monthly repayments because the interest rate does not change during the agreed period. Unlike variable-rate loans, where repayments may rise if market conditions change, fixed-rate mortgages allow households to plan their finances with greater confidence.

Longer repayment periods also reduce monthly instalments by spreading repayments over more years. For many first-time buyers, KMRC-supported mortgages finance up to 105 percent of a property's value, covering additional costs such as stamp duty, legal fees and insurance premiums that can otherwise delay a purchase.

Since it began operations, KMRC has refinanced 6,143 mortgages worth Sh32.4 billion through participating banks and saccos, helping thousands of households access home loans. Mortgage costs, however, continue to differ between lenders. 

Commercial banks set their own pricing based on funding costs, lending policies and borrower risk. Some lenders offer fixed rates only for an initial period before switching to variable rates, while others provide variable-rate mortgages throughout the loan term.

Oltetia says improving mortgage affordability requires reducing the underlying cost of long-term housing finance rather than focusing only on headline interest rates.

"It requires reducing the underlying cost of long-term housing finances. That is why KMRC focuses on expanding access to long-term refinancing, bringing more lenders, including saccos, into affordable housing finance and advancing risk-sharing initiatives that enable lenders to serve more households," he says.

His remarks come as Kenya's monetary policy becomes more accommodative. The Central Bank of Kenya has lowered its policy rate over the past year to encourage lending, although commercial lending rates have not fallen by the same margin. This means many prospective homeowners have yet to benefit fully from lower benchmark rates.

Mortgage specialists also advise borrowers to consider the full cost of a loan rather than focusing only on the advertised interest rate. Charges such as processing fees, valuation costs, legal expenses, insurance premiums, account maintenance fees and early repayment penalties can significantly increase the total cost of borrowing.

Choosing between fixed and variable interest rates is another important decision. Variable-rate mortgages may initially offer lower repayments, but costs can increase if interest rates rise. Fixed-rate mortgages provide greater certainty by protecting borrowers from future rate changes. For households working within fixed monthly budgets, predictable repayments can be more valuable than a lower introductory rate.

The wider economic environment also affects housing affordability. KNBS reported annual inflation of 6.4 percent in June 2026, with higher spending on food, transport and housing reducing disposable income. This makes it more difficult for many households to save for deposits or manage higher mortgage repayments.

Kenya's housing finance market is also becoming more diverse. While commercial banks have traditionally dominated mortgage lending, deposit-taking saccos are expanding their role through partnerships with KMRC. Greater access to affordable refinancing could help more middle-income earners qualify for home loans.

The growing involvement of saccos is also expected to increase competition among lenders, which could encourage more favourable mortgage terms while supporting wider access to home ownership. Financial advisers nevertheless recommend that borrowers carefully assess their ability to meet long-term repayment commitments before taking out a mortgage. 

Monthly repayments should allow enough income to cover essential household expenses, maintain emergency savings and meet future financial obligations. Building an emergency fund can also provide protection against unexpected events such as job losses or interruptions to business income.

Experts also advise comparing mortgage offers from several lenders before making a decision. Buyers should consider repayment periods, interest rate structures, fees, insurance requirements, refinancing options and early repayment charges. In some cases, a mortgage with a slightly higher interest rate but lower additional costs may prove cheaper over its full term than one with a lower advertised rate.
