Once a building is bought or built, someone has to run it. That someone is the property manager — either an in-house team of the owner or a third-party manager retained for a fee. The operational layer is where the model meets reality: where the modelled rent collection becomes M-Pesa transfers from tenants, where the modelled maintenance reserve becomes a leaking roof, where the modelled lease renewal becomes a negotiation in November when the tenant is comparing your asking price to the building next door.
What a property manager actually does
- Leasing — marketing vacant units, screening prospective tenants, negotiating lease terms, signing leases. Commercial leases require legal review; residential leases use standard templates.
- Rent collection — sending invoices, chasing late payments, depositing rent. In Kenya, primarily via M-Pesa Paybill numbers and bank transfers for institutional tenants. The collection rate (what % of billed rent actually arrives within 30 days) is a key operating KPI.
- Maintenance — preventive (routine inspections, scheduled service of HVAC and lifts, painting) and reactive (responding to tenant complaints, repairs, after-hours emergencies). Most managers maintain a vendor list and dispatch trades.
- Vendor management — utilities, security, cleaning, landscaping, pest control, garbage collection. Each is a separate vendor relationship and contract.
- Financial reporting — monthly statements to the owner showing income, expenses, occupancy, key tenant issues. Annual budget. Year-end audit-quality financial package for the owner's accountant or auditor.
- Tenant relations — fielding complaints, managing the body corporate (for sectional buildings), handling disputes, managing move-ins and move-outs.
Management fees
Property managers charge a percentage of Effective Gross Income, typically: residential 5-7%, commercial 2-4%, retail centres 3-5%. The lower commercial rate reflects that commercial tenants have longer leases and lower turnover, so the manager's work per-dollar-of-rent is lower. Additional fees: leasing commissions (charged when a new tenant is signed, typically 1 month rent for residential, 3-6% of total lease value for commercial), project-management fees for capital projects (5-10% of project cost), and onboarding fees when the manager first takes over a building. Self-managing your own building looks like a saving on management fees, but is usually a false economy for owners with day jobs — the manager's time and expertise are typically worth more than 5% of EGI.
Lease structures — who pays for what
GROSS LEASETenant pays a single all-in monthly amount.Landlord pays property tax, insurance, repairs, common-area maintenance.Tenant's risk: nothing on operating costs.Landlord's risk: full operating-expense inflation exposure.Used in: most Kenyan residential leases, some smaller commercial.TRIPLE-NET (NNN) LEASETenant pays rent + property tax + insurance + maintenance.Landlord's risk: structural repairs only.Used in: long-term single-tenant commercial (e.g. supermarkets,big-box retail, industrial), the Kenyan equivalent of a Walmartlease in the US.MODIFIED GROSS LEASETenant pays base rent. Operating expenses split per a specified rule(e.g. tenant pays expenses above a 'base year' threshold).Most middle-ground commercial leases in Kenya use some variation.SERVICE-CHARGE STRUCTURECommon in Kenyan apartments and offices: tenant pays base rent +monthly service charge. Service charge covers common-area costs andis reconciled annually. Economically a modified gross lease in disguise.
The cash-flow implication of lease structure is significant. Two buildings reporting the same KES 30m gross rent are not the same investment if one is gross and one is NNN — the NNN building's operating expenses are paid by tenants and don't hit the landlord's P&L. The honest comparison adjusts both to NOI, which strips out the structural difference. A 30m gross-rent gross-lease building with 35% operating expense ratio produces 19.5m NOI; a 30m gross-rent NNN-lease building produces close to 30m NOI.
Tenant retention economics
Most analysts undervalue tenant retention. The cost of losing a tenant is the sum of: (a) the vacancy period until replacement, typically 3-9 months for residential, 6-18 months for commercial, (b) the leasing commission paid to find the replacement, often 1 month rent residential / 3-6% of lease value commercial, (c) the tenant improvement allowance the new tenant negotiates, often 1-3 months of free rent or fit-out contribution, (d) the make-ready cost — painting, cleaning, minor repairs between tenants.
Worked example: a Kenyan office unit at KES 250,000/month. The current tenant asks for a renewal at flat rent versus a 5% market increase. Most landlords push for the increase and lose the tenant. The actual math: at flat rent, year-1 revenue 3.0m; at 5% increase, IF the tenant renews, 3.15m (gain 0.15m). If the tenant leaves: 9 months vacancy = 2.25m lost, 3-month leasing commission = 0.75m, tenant improvement 0.5m. Total cost of losing the tenant: 3.5m. The landlord's expected value calculation: 90% probability of renewal × 0.15m gain − 10% probability of loss × 3.5m loss = +0.135m − 0.350m = −0.215m. The risk-adjusted answer is to accept the renewal at flat rent.
Why senior asset managers obsess over retention
The single highest-leverage decision a property manager makes is the renewal negotiation with an existing tenant. The mathematical case for retention is so strong that institutional managers will offer below-market rent to retain a good tenant. The retained-tenant-at-95%-market is usually more valuable than the new-tenant-at-market because of the avoided friction costs.
Rent collection in Kenya — the M-Pesa reality
Almost all Kenyan residential rent flows through M-Pesa. The standard mechanism is a Paybill — a numeric ID assigned to the property manager — that tenants pay into each month with the rental unit's reference number as the account. The manager downloads daily statements, reconciles, and reports to the owner. M-Pesa's clearing is near-instant; the cash hits the property's account same-day. For institutional commercial tenants (banks, corporates), payment is typically by EFT to the property's bank account. For SMEs occupying commercial space, M-Pesa Paybills with limits raised to allow larger transactions are increasingly common.
The collection mechanism shapes operational economics. M-Pesa-based collection has roughly 1% transaction cost (the M-Pesa charge passes to the operator, sometimes recharged to the tenant via the service charge). It also produces clean, time-stamped, auditable records — far better than the cash-receipt era — making landlord-tenant disputes more tractable. The transparency comes with a downside: tenants who could previously delay rent and claim 'I'll pay tomorrow' now have a digital trail of when they paid, which means defaults are detected faster and harder to dispute.
The formal-informal split
A significant share of Kenya's rental housing — by some estimates 30-50% of urban rental units — operates outside the formal property-management infrastructure. Owners collect rent themselves, often in cash or via personal M-Pesa, with no formal lease and no professional manager. This informal sector is hard to study and harder to invest in institutionally. The implication for a real-estate analyst: when assessing market data, the visible institutional segment is a fraction of the total rental market, and trends in the formal segment may not generalise to the informal segment.
Exercise
You manage a 40-unit Westlands apartment block with EGI of KES 24m/year. Monthly base rent per unit averages KES 50,000. A long-tenured tenant (3 years in unit, always paid on time) is leaving — they got a job in Mombasa. Replacing them: estimated 4 months vacancy, leasing commission to the broker of 1 month rent, minor make-ready (paint, fix kitchen tap, deep clean) ~ KES 35,000. The replacement market rent for this unit is KES 53,000. (1) Compute the all-in cost of losing this tenant. (2) Compute the present-value gain (1-year horizon) from getting market rent on the new tenant. (3) Was the departing tenant worth retaining if the landlord could have prevented departure by, say, dropping their rent to KES 45,000? (4) The same 40-unit building has annual turnover of 8 units (20% turnover). At an average vacancy + leasing + make-ready cost similar to this case, what is the annual cost of turnover? Compare against the gross rent and reflect on what 'lowering turnover by 25%' would do for the building's bottom line.
