Every deal is also a bet on a market. The cap rate you negotiated at acquisition reflects the market's current view; the cap rate you exit at reflects the market's view five or ten years later. Market analysis is the discipline of forming a defensible view on where the market is in its cycle and where it is going. It separates the analyst who underwrote a great deal at the wrong time from the analyst who picked a great market and then executed competently inside it.
The supply side — what's being built
- Pipeline — buildings currently under construction or planned. Visible: you can count cranes, see permits filed at the local authority, observe announcements. A pipeline of 1 million sqm of new office in a market currently absorbing 200,000 sqm per year is 5 years of forward supply waiting to land.
- Completions — buildings actually delivered (issued certificates of occupancy) in a given period. The rate at which supply enters the market. Trailing indicator of pipeline.
- Absorption — square footage occupied this period that wasn't last period. Gross absorption counts all new occupations; net absorption (gross absorption minus vacated space) is the right number — it measures whether the market actually grew.
- Vacancy rate — percentage of total stock that is currently unoccupied. The single most-cited market-health indicator. In healthy stabilised markets: residential 5-8%, office 8-12%, retail 5-10%, industrial 3-7%. Higher than those ranges = oversupply; lower = constraint.
- Stock — total square footage in the market by product type. The denominator everything else is normalised against. Cumulative over decades; changes slowly.
The demand side — who's actually using the space
- Employment growth — the single best leading indicator for office demand. Each new white-collar job typically requires 10-15 sqm of office space. If Nairobi adds 30,000 white-collar jobs in a year, that's roughly 400,000 sqm of new office demand.
- Household formation — for residential. New households (driven by population, urbanisation, age structure) create rent demand. Kenya's household formation rate is high (population growth + urbanisation + falling household size) — structurally bullish for residential.
- Population & demographics — slower-moving but enormously important. The 18-34 age share, the urban share, the rural-urban migration rate — each shapes long-term demand.
- GDP per capita — broad demand driver. Each percentage point of real GDP per capita growth raises real estate demand 1.2-1.8× depending on sector (residential most income-elastic, then office, then retail).
- Sector-specific drivers — retail tracks consumption growth and e-commerce share; industrial tracks trade and logistics flows; hospitality tracks tourism arrivals and business travel; data-centre demand tracks cloud and connectivity adoption.
The four-phase market cycle
Rents ▲││ ╱ HYPER-│ ╱ SUPPLY│ ╱ ╲│ EXPANSION ╲│ ╱ ╲│ ╱ ╲│ RECOVERY RECESSION│___________________________________→0% Vacancy ~25%RECOVERY — Vacancy is high and falling. Rents are flat. No newconstruction. Investors with capital are picking updistressed assets cheaply.EXPANSION — Vacancy is dropping toward long-term equilibrium.Rents start growing. New construction begins. Themarket 'feels good'. Most deals close in this phase.HYPERSUPPLY — Construction continues past equilibrium because pipelinewas set during expansion. Completions exceed absorption.Vacancy starts climbing again. Rents flatten or fall.The phase that produces the painful losses for late-stagedevelopers.RECESSION — Vacancy peaks. Rents drop. New construction halts.Some completed buildings sit empty for years. The phasethat produces buying opportunities for the patient.
Knowing where a market sits in this cycle is the most-important judgement a real-estate analyst makes. The four phases differ in what makes money: in recovery, buy stabilised income properties at depressed cap rates. In expansion, develop new product. In hypersupply, sell. In recession, hold cash and wait. Most institutional money flows OPPOSITE to where it should — buying enthusiastically in late expansion and into hypersupply, then selling at the bottom of the recession. The discipline to act contrary to the crowd is what separates above-average performers from average ones.
Case study: the Nairobi office cycle 2014-2024
Between roughly 2010 and 2014, Nairobi office rents climbed from KES 80-90/sqm/month to KES 120-140/sqm/month. Vacancy was below 5%. Yields were 9-10%. The conditions met every textbook definition of an expansion phase, and developers responded. From 2014 onward, an estimated 5 million sqm of new Grade A and Grade B office space entered the pipeline. By 2018-2019, completions were running 600-800,000 sqm per year against net absorption of 200-300,000 sqm. The market was in hypersupply by 2017-2018 — vacancies climbed past 20%, then past 25%, and rents fell 15-25% from peak. The pandemic in 2020 made the picture worse: remote work compressed office demand permanently in many submarkets. As of 2024, Nairobi Grade A vacancy sits 15-22% depending on submarket, with effective rents (after concessions) 25-35% below the 2014 peak in real terms. Several major developers who came up in 2014-2018 have either restructured, sold portfolios at a loss, or quietly exited the segment.
The case study lessons: (a) pipeline matters more than rent in late-expansion phases. By 2014 the pipeline was already too big — anyone looking at planning permissions could have seen it. (b) The lag between permit and delivery is 24-36 months. Hypersupply phases therefore play out slowly enough that the smart players exit before the obvious deterioration. (c) Once oversupply is visible to everyone, the cycle is well into the painful phase. The right time to call it is early — before the news headlines, when the pipeline numbers say what's coming.
What an analyst should track weekly
- Permit filings at the major county authorities (Nairobi, Mombasa, Kiambu, Machakos). New permits are the earliest visible supply signal.
- Construction-site count by submarket. A walk through Westlands tells you more than most quarterly reports.
- Rent rolls of comparable buildings, where accessible. Specific data points beat aggregate averages.
- Major tenant relocations and lease expiries. A single 50,000-sqm anchor tenant decision moves a submarket.
- REIT pricing and discount-to-NAV trends. The public-market signal lags but is informative.
- KMRC mortgage volumes (for residential). The mortgage market's growth is the demand-side counter to development supply.
- Cytonn, HassConsult, Knight Frank, and JLL quarterly research. Triangulate; no single source is right alone.
Exercise
Submarket: Kilimani residential. Current vacancy 8%, ten years ago vacancy 4%. Current rent KES 50,000/month for a 2-bedroom, ten years ago equivalent rent (in real terms) KES 48,000. Pipeline: 12 new buildings of average 30 units each in active construction, expected completion in the next 18 months. Net absorption over the last 5 years has averaged 200 units/year. (1) Approximately how many new units will the pipeline deliver, and how does that compare to 5 years of absorption? (2) Which of the four phases of the cycle is Kilimani residential most likely in? (3) Given your phase identification, what action would you recommend for: an investor with KES 100m to deploy into Kilimani residential, a developer holding land in Kilimani who has not yet started construction, a current owner of 4 stabilised buildings in Kilimani?
