The Ultimate Guide to Kenyan Mortgages
Are you ready to buy? The five-test readiness dashboard
A property that looks affordable is not the same as being ready. Buy when you pass all five tests below, not just when the listing price fits your imagination.
Read this slide as text
Instalment limit
Of net monthly income. KMRC's absolute ceiling is 40%.
Cash on hand
Deposit ready, plus the hidden transaction costs.
Emergency fund
Living expenses and mortgage instalments, saved separately.
Time horizon
You plan to keep the home for at least this long.
Rate buffer
You can survive an interest rate rise of 2–3 percentage points.
Test 1 matters most. Lenders commonly cap total deductions, and a mortgage that eats more than a third of your take-home pay leaves little room for school fees, transport or a bad month. Section 8 shows how much cash Test 2 really needs.
How a Kenyan mortgage works: the reducing-balance method
Most Kenyan mortgages use a reducing-balance method. Interest is charged only on the outstanding balance, so extra payments directly cut future interest. Early instalments are mostly interest; late ones are mostly principal.

Where each year's repayments go
KES 5 million loan, 9.5% reducing balance, 20 years. Annual interest vs principal repaid.
Four kinds of mortgage
Purchase
Buying an existing home or apartment.
Construction
Building on land you own. Funds are released in stages.
Equity release
Unlocking cash tied up in property you already own.
Diaspora
For Kenyans abroad, with income assessed overseas.
The KMRC advantage: how cheaper money reaches you
The Kenya Mortgage Refinance Company (KMRC) is a wholesale funding partner, not a direct lender. It lends long-term money to banks and SACCOs at a low cost, and they pass part of that saving to you.

Wholesale funder
Provides long-term, lower-cost funding into the financial system.
Participating banks and SACCOs
Primary lenders add their margin, assess your credit and package the mortgage.
The buyer
You receive longer tenors (up to 25 years) and single-digit fixed rates (8.99%–9.9%).
Some KMRC-backed campaigns go further on loan size. KCB's published offer, for example, finances up to 105% of the property value (the extra 5% covers associated costs) with a maximum loan of KES 10.5 million. If a lender offers this, a deposit may not be required, so ask. Section 12 lists what else to ask.

Market snapshot: current mortgage rates (October 2026)
The lowest rates sit in KMRC-backed and promotional products. Everything else is variable and priced to your risk.

Advertised mortgage rates by lender, % a year
Rates compiled by WeCompare from lender publications in October 2026. KCB's 8.9% is a fixed-rate campaign running 15 May to 31 December 2026, per KCB's own page. Rates and campaign dates change often.
Central Bank Rate
8.75%Held by the CBK's Monetary Policy Committee on 7 October 2026. Next meeting: December 2026.
Average bank lending rate
14.4%September 2026, up from 14.3% in August, per CBK data reported by The Kenya Times.
Fixed vs variable rates: a strategic choice
Rates have moved within a wide range recently: the average bank lending rate was 17.2% in November 2024 and 14.4% in September 2026. That swing is the argument for fixing when your budget is tight.

Fixed-rate mortgage
- Mechanic
- Your instalment is locked and predictable.
- Advantage
- Full protection against market rate hikes. Common in KMRC products.
- Risk
- You miss out if national interest rates fall.
- Best if
- A 10–15% rise in your monthly payment would strain your budget.
Variable-rate mortgage
- Mechanic
- Your instalment moves with the central market.
- Advantage
- Cheaper payments if rates fall.
- Risk
- Payment shock if rates rise unexpectedly.
- Best if
- You have strong cash-flow buffers and can absorb higher payments.
The affordability rule: income vs buying power
Allocate a safe 30% of your net monthly income to a 20-year mortgage. How much property that supports depends heavily on your interest rate. Use the chart, then try your own numbers below it.

The hidden costs iceberg
The 15% deposit is just the tip. Expect 6–8% in additional transaction costs. Here is a KES 8 million home.

15% deposit
KES 1,200,000| Stamp duty (4%, urban) | KES 320,000 |
| Legal fees (about 1.5%) | KES 120,000 |
| Valuation | KES 35,000 |
| Bank and registration charges | KES 50,000 |
| Subtotal (6.6% of price) | KES 525,000 |
Stamp duty is paid by the buyer: 4% in urban areas and gazetted towns, 2% elsewhere, on the higher of sale price or government valuation (Nash Thuo, updated July 2026). Legal, valuation and bank charges vary by firm and lender; the figures above are planning estimates.

How to compare offers: the right questions
Never accept the advertised rate on its own. Ask these four questions before you sign.
Read this slide as text
| Ask the lender | Why it matters |
|---|---|
| What is the all-in annual rate after fees? | Uncovers the true cost, not just the headline marketing rate. |
| What will I pay today, and if the rate rises by 2%? | Stress-tests your budget against future variable-rate shocks. |
| Do I qualify for KMRC-backed pricing? | Forces the lender to check whether you are eligible for single-digit fixed rates. |
| Can I overpay or settle early without a penalty? | Ensures you are not punished for clearing your debt faster. |

Frequently asked questions
Can I apply directly to KMRC?
No. KMRC funds banks and SACCOs, which lend to you. Apply through a participating lender and ask whether you qualify for KMRC-backed pricing.
How much deposit do I need for a mortgage in Kenya?
Plan for 10–20% of the price, plus 6–8% for stamp duty, legal, valuation and bank charges. Some KMRC-backed campaigns finance up to 105% of value, so ask each lender what it requires.
Should I choose a fixed or variable rate?
Choose fixed if a 10–15% rise in your instalment would strain your budget. Choose variable only if you hold strong cash-flow buffers and can absorb higher payments.
What is the maximum property value for KMRC-backed loans?
Open-market value is capped at KES 15 million, and KCB's published offer caps the loan at KES 10.5 million. Confirm current limits with your lender.
How much interest can I deduct from tax?
Up to KES 360,000 a year on interest for an owner-occupied home, according to PwC Tax Summaries. Confirm your own eligibility with KRA or a tax professional.
Banks or SACCOs: which is better?
Banks suit larger loans, longer tenors and KMRC-backed products. SACCOs suit established members with a steady savings record, but loan sizes are often capped by available funds.
