In this guide, we explore the hidden costs you should consider when buying an apartment in Nairobi and explain what each expense means for your overall budget.
Why You Should Look Beyond the Purchase Price
When you find an apartment within your budget, it can be tempting to assume that the advertised price represents the total amount you will need to pay.
However, buying property involves several other expenses.
For example, a buyer purchasing an apartment for KSh 15 million may need to budget for legal services, stamp duty, valuation, registration, and available amenities such as (shopping centres, healthcare facilties, schools). Other transaction-related costs in addition to the purchase price.
Understanding these costs before committing to a property allows you to calculate your true costs of buying an apartment in Nairobi and determine whether the purchase is financially comfortable.

1. Stamp Duty
Stamp duty is one of the major additional costs associated with purchasing property in Kenya.
It is a government tax payable when property ownership is transferred to the buyer. The amount depends on the property’s value and the applicable location and transaction rules.
Because stamp duty can represent a significant amount, buyers should factor it into their budget before purchasing an apartment.
What Buyers Should Know
The applicable stamp duty rate and valuation basis can depend on the type and location of the property. Therefore, it is important to confirm the current requirements with your advocate or the relevant government authority before completing the transaction.
2. Legal Fees
Hiring a qualified property advocate is an important part of buying an apartment.
Your lawyer can help with:
- Reviewing the sale agreement
- Conducting legal due diligence
- Verifying ownership documents
- Checking the property’s title
- Reviewing development documents
- Advising on payment terms
- Handling the transfer process
- Registering the property in your name
Legal fees will vary depending on the transaction and advocate involved.
Although this is an additional expense, professional legal advice can protect you from costly mistakes and contractual problems.
3. Property Valuation Fees
If you are financing your apartment through a mortgage, the lender may require an independent valuation of the property.
A professional valuer assesses the property’s market value and provides a valuation report to the lender.
The valuation fee is generally paid by the buyer.
Even when purchasing without a mortgage, an independent valuation can sometimes be useful because it provides another perspective on whether the property’s asking price reflects its market value.
4. Registration and Transfer Costs
Once you purchase an apartment, ownership needs to be legally transferred and registered.
This process can involve various government and administrative charges.
Your advocate should explain the applicable registration and transfer costs before you complete the transaction.
It is important not to assume that these expenses are automatically included in the advertised purchase price.

5. Service Charges
Service charges are particularly important when buying an apartment.
Unlike a standalone home, apartment owners share responsibility for maintaining common areas and facilities within the development.
Service charges may contribute towards:
- Security
- Cleaning
- Landscaping
- Lift maintenance
- Swimming pool maintenance
- Gym maintenance
- Common-area electricity
- Waste management
- Property management
- Backup generator maintenance
- General building repairs
The amount varies significantly between developments.
Why Service Charges Matter
A luxury development may have extensive facilities and therefore higher operating costs. Before buying, ask the developer or property manager for details of the service charge and what it covers.
You should also find out whether the service charge is paid monthly, quarterly, or annually.
6. Parking Costs
Not every apartment purchase automatically includes a parking space.
Some developments include parking in the purchase price, while others sell parking separately.
If you own a vehicle, confirm:
- Whether parking is included
- How many parking spaces are allocated
- Whether additional spaces can be purchased
- Whether visitors’ parking is available
- Whether parking attracts a separate service charge
This can make a meaningful difference to the overall cost of your apartment.
7. Mortgage-Related Costs
If you are financing your apartment through a mortgage, there may be additional costs beyond the monthly loan repayment.
Depending on your lender and loan structure, these can include:
- Mortgage processing fees
- Valuation fees
- Legal fees
- Insurance
- Credit-related charges
- Property registration costs
Before taking a mortgage, ask your lender for a complete breakdown of all upfront and ongoing charges.
Comparing different financing options can help you find a structure that fits your budget.

8. Property Insurance
Home insurance can be another cost to consider, particularly when financing your purchase through a mortgage.
A lender may require certain insurance coverage as part of the loan agreement.
Even without a mortgage, insurance can provide valuable protection against certain risks affecting the property.
Ask your insurer or lender what coverage is required and whether the cost is paid monthly or annually.
9. Moving and Furnishing Costs
Once the legal process is complete and you receive your apartment, there are still costs associated with moving into your new home.
These may include:
- Moving services
- Furniture
- Appliances
- Curtains and blinds
- Lighting
- Kitchen equipment
- Interior decoration
- Internet installation
For a first-time buyer, these expenses can add up quickly.
Creating a separate moving and furnishing budget can help prevent you from using money reserved for your property-related expenses.
10. Renovation and Customization Costs
A new apartment may require additional work before it completely matches your preferences.
Depending on the property, you may want to invest in:
- Built-in wardrobes
- Kitchen upgrades
- Lighting
- Flooring
- Interior painting
- Bathroom upgrades
- Smart home features
- Custom cabinetry
If you are purchasing an older apartment, renovation costs could be considerably higher.
Therefore, inspect the property carefully and estimate any improvements before finalizing your budget.
11. Utility and Connection Costs
New homeowners may also need to account for utility-related expenses.
These can include:
- Electricity connection
- Water connection
- Internet installation
- Gas installation, where applicable
- Security system installation
Ask the developer or property manager which utilities are already connected and which costs will be your responsibility.
12. Maintenance and Repair Costs
Owning an apartment means taking responsibility for maintaining your individual unit.
While the service charge generally covers shared facilities, owners may still be responsible for repairs and maintenance inside their apartments.
Examples include:
- Plumbing repairs
- Electrical work
- Appliance repairs
- Painting
- Air conditioning maintenance
- Fixtures and fittings
Setting aside a small maintenance fund can help you deal with unexpected expenses without disrupting your finances.
How Much Should You Budget Beyond the Apartment Price?
There is no single percentage that applies to every apartment purchase because the additional costs depend on factors such as:
- Property value
- Location
- Whether you are using a mortgage
- Legal fees
- Applicable taxes
- Property valuation
- Registration requirements
- Service charges
- Parking arrangements
- Developer terms
Instead of relying on a general percentage, ask for a complete cost breakdown before making a financial commitment.
Your advocate, lender, and developer should be able to explain the costs that apply to your specific purchase.

Questions to Ask Before Buying an Apartment
Before paying a deposit, ask the developer or seller:
Is the advertised price inclusive of all applicable costs?
Clarify exactly what is included in the quoted purchase price.
Is parking included?
If not, find out how much an additional parking space costs.
How much is the service charge?
Ask what the service charge covers and how frequently it is paid.
Are there additional legal or registration costs?
Your advocate should provide a clear breakdown.
Are there any outstanding charges on the property?
This is particularly important when purchasing a resale apartment.
What documents will I receive after completing the purchase?
Make sure you understand the ownership documentation and transfer process.
How to Avoid Unexpected Costs When Buying an Apartment
A little preparation can help you avoid unpleasant surprises.
Request a Full Cost Breakdown
Don’t base your budget solely on the property’s advertised price. Ask for all expected costs before making a commitment.
Work With a Qualified Property Advocate
An experienced advocate can identify legal and financial obligations that you may otherwise overlook.
Research the Development
Understand the developer, management structure, amenities, service charges, and ownership arrangements before purchasing.
Compare Multiple Properties
Looking at several developments can help you understand what is included in the purchase price and which property offers the best overall value.
Keep an Emergency Buffer
Avoid spending every available shilling on the purchase itself. Keeping additional funds available can help cover unexpected expenses after completion.
