METHODOLOGY BEFORE MEASUREMENT
Why Headline Property 'Yields' Are Meaningless Without Standardized Accounting Definitions
In East African commercial real estate, sellers and promoters frequently quote attractive '10% to 12% yields' calculated by dividing theoretical 100%-occupied asking rents by the purchase price—ignoring structural vacancy, unrecovered service-charge leakage, land rates, insurance, management fees, arrears write-offs, and capital replacement reserves.
This page sets out the transparent analytical methodology Wealth Matrix uses when evaluating commercial property performance for private owners and institutional acquirers. No fabricated index reading, sample dataset, or guaranteed return is published here.

How Institutional Analysts Measure Commercial Real Estate Performance
Any credible property yield analysis must account for six distinct variables.

02. Economic Vacancy & Collection Loss

FOUR QUESTIONS TO TEST ANY PROPERTY RESEARCH
Evaluating Real Estate Data With Institutional Skepticism
Questions every property investor or family board should ask before relying on a yield figure.
YQ1-01
Is the Sample Universe Clearly Defined?
Does the study specify the exact sub-market (e.g., Westlands Grade-A Office vs. Industrial Area Warehousing), sample size, and observation period?
SAMPLE UNIVERSE
YQ1-02
Are Gross and Net Yields Separated?
Is the quoted yield a rough Gross Yield or a true Net Operating Income (NOI) Yield after all non-recoverable landlord costs?
GROSS VS NET
YQ1-03
Are Valuations Based on Completed Deals?
Are capital values derived from verified completed transactions and registered valuations, or optimistic seller asking prices?
TRANSACTION BASIS
YQ1-04
How Are Taxes and Financing Treated?
Does the return calculation reflect pre-tax property NOI, or post-tax cash-on-cash equity return after debt service and rental tax?
PRE VS POST TAX
YQ1-05
What Are the Lease Escalation Mechanics?
Are leases denominated in KES or USD, and do annual escalations track inflation without pushing rents above market replacement levels?
ESCALATION RISK
YQ1-06
Are Historical Yields Treated as Guarantees?
Past or illustrative property yields never guarantee future occupancy or returns

Standardized Definitions Used in Wealth Matrix Property Audits
How we bridge from Potential Gross Income to Net Cash Flow.
| Metric Code | Property Metric | Standardized Formula / Definition | Analytical Purpose |
|---|---|---|---|
| Y-PGI | Potential Gross Income (PGI) | 100% Lettable Area × Contracted / Market Rent | Theoretical top-line ceiling |
| Y-EGI | Effective Gross Income (EGI) | PGI − Physical Vacancy − Credit/Arrears Collection Loss + Ancillary Parking Income | Actual collected top-line revenue |
| Y-NOI | Net Operating Income (NOI) | EGI − Unrecovered Service Charge − Landlord OpEx (Rates, Insurance, Mgmt Fees) | Core unlevered property operating cash flow |
| Y-NCF | Adjusted Net Cash Flow (NCF) | NOI − Annualized Capital Replacement Sinking Fund (CapEx) − Leasing Commissions | True sustainable distributable cash flow |
| Y-NET | True Net Initial Yield (%) | Annualized NOI (or NCF) ÷ (Purchase Price + Stamp Duty + Transaction & Fit-Out Costs) | Comparable institutional yield benchmark |

Frequently Asked Governance & Mandate Questions
Clear answers regarding scope, confidentiality, fees, and professional boundaries at Wealth Matrix Limited.
Because commercial buildings even on the same street in Westlands or Upper Hill vary dramatically in WALE, tenant quality, service-charge recovery, and physical maintenance. Publishing a single static number without a verified, audited dataset can mislead investors. Instead, we apply this rigorous methodology directly to your portfolio or target acquisition.
Yes. Through our Wealth Creation & Commercial Property practice (/advisory/wealth-property-management/), we audit your rent rolls, service-charge accounts, and operating expenses to calculate true net yield and identify improvement opportunities.
