After a client's first unit does well, the same question comes back: "Where do I take the second one?" The common mistake is repeating the answer — same district, same developer — because "I already know that area". The result is a portfolio that behaves like a single asset: any shock to one district hits everything at once.
Good allocation is not a complex technical judgement. It is a handful of simple rules that tell you what to buy, where, and at what size — so if one part falls, the rest keep going. Every figure here is an estimate or an illustrative model, not a return forecast.
1) The 25% rule — the ceiling for any single party
The simplest diversification rule you can keep without a calculator: any single exposure above a quarter of your portfolio's value is a large concentrated risk. Measure it across:
- District: three flats in one district at 900,000 each is over-concentration.
- Developer: one developer late on delivery means the whole portfolio is late.
- Property type: all retail units, or all apartments, repeats the same risk.
- One tenant: a shop paying 40% of monthly income is a shock if it leaves — see commercial vs residential property.
Quick example: on a 3 million portfolio, two flats in one district worth 1.6 million put 53% into one area — the rule broken from step one. The fix is not a rushed sale: pause new buying in that district until the share drops. The rule is measured on today's market value, not on what you paid — diversification has to move with prices.
A strong portfolio is not the one that earns most in the best year — it is the one that does not bleed in the worst year. Diversification raises your sleep, not your returns.
2) Split by property stage, not just by type
Every portfolio has three "buckets", by the stage each asset is in:
Bucket one — income-ready: a delivered unit rented today. This is the spine of the portfolio: money every month that covers instalments and running costs. The rule we give clients: a unit that brings in nothing is a burden, not an asset.
Bucket two — under development: off-plan or under construction. Capital committed, no income until handover — and delivery may slip a year or more. Size it so it can sit frozen for two years.
Bucket three — land and opportunities: real upside, unconfirmed — and poor liquidity. What grows the portfolio long term, provided it stays under a third and is not all in one place.
3) A sample allocation for a mid-sized portfolio
If your portfolio is worth EGP 3 million (illustrative only), one workable split:
| Category | Share | Approximate amount | Role in the portfolio |
|---|---|---|---|
| Rented residential flats | 60% | 1.8 million | Stable monthly income, instalment cover |
| Shops / offices | 25% | 750,000 | Longer leases, higher yield |
| Land or a unit under development | 15% | 450,000 | Capital growth over 3 – 5 years |
Why these weights? Residential at 60% for steady rent and an easy exit. Commercial at 25% for higher yield — but it needs careful site selection. Land at 15% grows slowly and sells slowly: carry it in the plan, don't let it carry the plan. Keep the 25% rule intact inside each category too — and if you want ready units, start from the projects page.
4) Geography: cities and areas
Spatial diversification in Egypt hangs on one aim: not all the money in the place you cannot easily watch.
- Your home governorate: easier to manage, steady income — keep it under half the portfolio.
- A second city with a different growth driver: the North Coast is seasonal; the New Capital is still in occupancy — "growth" lines, not "income" lines.
- Outside Egypt: start with real estate vs stocks vs gold before comparing property alone.
Cap any governorate other than yours at 10% – 30%, depending on how well you can manage from a distance.
5) Rebalancing, and the mistakes that undo it
The split does not fix itself: after a year, the flat may be 70% of the portfolio instead of 60%. In the annual review, update every unit to today's market price, find where the shares have drifted, and add to the underweight side or sell down the overweight side.
- One large unit: 3 million in a single flat is one risk wearing a portfolio's name.
- Buying twice with no income: two off-plan units with a slipping delivery pressures the budget.
- Ignoring running costs: repairs, voids and taxes — if they are not in the maths, the return shrinks.
- An inherited property left untouched: run it through the evaluation checklist first.
- Consumer loans against a rental property: interest eats the return — see comparing bank financing.
Practical steps to start today
- List every property on one page with an approximate market value.
- Calculate shares: per district, per developer, per type.
- Flag anything above 25% — that is the first fix.
- Place every unit into the three buckets, and set an annual review date.
- Before any new purchase, ask: "Which drifted share does this repair?"
