A Kenyan earning KSh200,000 a month has done well.
They may be a manager, engineer, banker, doctor, senior civil servant, technology worker or established professional. On paper, it is the kind of salary many people associate with a good home, a reliable car and a reasonably comfortable life.
Then the mortgage mathematics begins.
A gross salary of KSh200,000 does not comfortably finance the average home being advertised in Nairobi’s better known residential districts. Depending on the interest rate, loan term, existing obligations and the amount the household is willing to commit every month, the borrower may qualify for a mortgage of roughly KSh5 million to KSh10 million.
That is a wide range.
It is also the clearest explanation for why a person can earn a strong salary and still find Nairobi property out of reach.
The salary on the payslip is not the money available to the household
A gross monthly salary of KSh200,000 is reduced before it reaches the bank account.
There is the Affordable Housing Levy, which takes 1.5 percent of gross pay, or KSh3,000. The Social Health Insurance contribution at 2.75 percent amounts to KSh5,500. Under the current NSSF schedule, the employee contribution for a worker in this income bracket can reach KSh6,480 a month.
PAYE then takes the largest share.
Using the current tax bands and a simplified calculation, a person earning KSh200,000 gross may take home approximately KSh137,000 after PAYE, SHIF, the housing levy and the maximum employee NSSF contribution.
The actual figure will vary according to pension contributions, insurance, tax reliefs, salary advances, SACCO deductions and other arrangements.
But the broad point remains the same.
The bank may assess income beginning at KSh200,000. The household has to live on something closer to KSh137,000.
That difference matters because a mortgage payment is not the only serious expense in a household budget. Food, transport, school fees, rent, electricity, insurance, medical costs, family support and emergencies continue long after the bank has approved the loan.
How much should go to the mortgage?
Lenders make their own affordability decisions. There is no single repayment limit applied identically by every bank.
As a planning guide, however, many borrowers use a mortgage payment of between 30 and 40 percent of gross income as the outer range.
For a KSh200,000 salary, that means:
30 percent: KSh60,000 a month
35 percent: KSh70,000 a month
40 percent: KSh80,000 a month
KSh80,000 may look manageable when compared with a gross salary of KSh200,000. It is a very different proposition when compared with a take home pay of approximately KSh137,000.
At that level, the mortgage would consume close to 60 percent of the money entering the household account.
The bank may approve it. That does not automatically make it comfortable.
A sensible buyer should ask a more useful question than, “How much will the bank lend me?”
The better question is, “How much can I repay while still keeping the rest of my life financially stable?”
At current borrowing costs, the mortgage remains modest
The Central Bank of Kenya reported that the average commercial bank lending rate stood at 14.39 percent in July 2026. The Central Bank’s latest detailed residential mortgage survey recorded an average mortgage rate of 14.9 percent in 2024.
Using a rate around the mid 14 percent range as a working example, a monthly repayment of KSh80,000 supports a mortgage of approximately:
KSh6.1 million over 20 years
KSh6.3 million over 25 years
Reducing the payment to KSh60,000 lowers the borrowing capacity to approximately KSh4.6 million over 20 years.
At KSh70,000 a month, the figure is roughly KSh5.3 million.
The difference between a 20 year and 25 year term is smaller than many borrowers expect. At a high interest rate, much of the early repayment goes towards interest. Extending the loan by five years does not create as much additional purchasing power as it would at a much cheaper rate.
The problem is therefore not only the price of homes.
It is the price of money.
What changes when the interest rate falls to nine percent?
Two current mortgage campaigns have placed fixed rates below nine percent in the market.
KCB is advertising a fixed rate from 8.9 percent for qualifying borrowers, with a campaign period running to September 15, 2026. Stanbic is advertising an 8.99 percent KMRC linked affordable housing loan, with its current offer running to September 30.
These are advertised products, not automatic entitlements. Eligibility, property value, income, existing debt, documentation and the lender’s approval process still apply.
But they provide a useful illustration of what interest rates do to affordability.
At 8.9 percent over 25 years:
KSh60,000 a month supports approximately KSh7.2 million
KSh70,000 a month supports approximately KSh8.4 million
KSh80,000 a month supports approximately KSh9.6 million
The salary has not changed. The house has not changed. Only the interest rate has changed.
Yet the borrower paying KSh80,000 a month gains more than KSh3 million in theoretical borrowing capacity compared with a mortgage priced around 14.9 percent.
That is the part of homeownership many buyers underestimate. A cheaper house reduces the price once. A lower interest rate reduces the cost of borrowing every month for decades.
The deposit is where the picture becomes more complicated
Suppose the buyer has saved KSh3 million.
At a mid 14 percent mortgage rate, a KSh80,000 repayment may support about KSh6.1 million. Together, the buyer has a theoretical purchase budget of approximately KSh9.1 million.
At 8.9 percent, the same repayment supports about KSh9.6 million. With the same savings, the theoretical budget rises to approximately KSh12.6 million.
But the entire KSh3 million cannot necessarily be treated as a deposit.
Buying property also involves stamp duty, valuation, legal fees, mortgage registration, insurance, bank charges and moving costs. Stamp duty on an urban property is generally 4 percent of the assessed value.
On a KSh12 million home, stamp duty alone can approach KSh480,000.
This is why “I have KSh3 million saved” and “I have KSh3 million available as equity” are not necessarily the same statement.
A buyer who uses every shilling of savings for the deposit may complete the purchase without enough cash for the costs that come immediately afterwards.
Existing loans can reduce the house by millions
The salary figure also hides the effect of existing debt.
Imagine the same employee already pays:
KSh25,000 for a car loan
KSh15,000 for a SACCO or personal loan
That is KSh40,000 of existing monthly debt.
If the household has decided that KSh80,000 is the maximum total debt repayment it can carry, only KSh40,000 remains for the mortgage.
At 8.9 percent over 25 years, KSh40,000 supports approximately KSh4.8 million.
At around 14.9 percent, it supports approximately KSh3.1 million.
The applicant still earns KSh200,000. But their borrowing position is no longer the same as that of someone with no existing obligations.
A car bought on credit can therefore reduce a person’s home buying power by several million shillings, even when the salary remains unchanged.
Why Kenya’s mortgage market remains small
The Central Bank recorded 30,016 residential mortgage loans in Kenya at the end of 2024. The total value of those loans was KSh279.3 billion, with an average loan size of approximately KSh9 million.
For a country of more than 50 million people, that is a remarkably small mortgage market.
The same report recorded non performing residential mortgage loans worth approximately KSh46 billion, equal to 16.5 percent of gross mortgage loans.
Those figures explain why banks examine affordability so closely. Mortgage approval is not simply a question of whether a person earns enough to make the first repayment. It is a long term test of whether the household can continue paying through illness, job loss, school expenses, higher living costs and changing interest rates.
So what can a KSh200,000 salary buy?
There is no universal answer.
A single earner on KSh200,000 gross, with no significant existing debt, may reasonably fall within this broad range:
Around KSh5 million to KSh6.5 million in mortgage borrowing at conventional mid teen rates
Around KSh7 million to KSh10 million under an unusually low fixed rate, subject to the lender’s product limit and approval
Savings can raise the total purchase price. A spouse’s income can change the picture substantially. Existing loans can reduce it just as quickly.
This places the single earner more naturally in lower priced apartments, selected satellite town markets, smaller homes or properties requiring a meaningful cash contribution. It does not place a KSh15 million or KSh20 million Nairobi home comfortably within reach on salary alone.
The uncomfortable conclusion is also the useful one.
KSh200,000 is a strong salary.
It is not, by itself, a Nairobi property cheat code.
The home a person can safely afford is determined by the amount left after deductions, the cost of borrowing, the debt already on the payslip and the amount of life the household still needs to finance after the bank has been paid.
That is the real affordability test.
Not the salary printed at the top of the payslip.
