A worked example of three Saudi assets held together, showing how income shocks behave differently at portfolio level and what the structure of the debt decides.
A portfolio is not three models stapled together. Income shocks average differently, costs spread differently, and the structure of the debt decides whether a problem at one asset stays there. The illustrative example below holds three Saudi assets side by side and tests the same loss of income at two different places in the portfolio.
The situation
An investor holds three Saudi income assets and wants to understand the portfolio rather than the assets: what the blended return is, how a single income shock behaves depending on where it lands, and whether a single facility across all three helps or harms.
Assumptions (illustrative)
- Asset A: twelve residential units, net operating income SAR 420,000, price SAR 6,500,000.
- Asset B: eight residential units, net operating income SAR 290,000, price SAR 4,200,000.
- Asset C: a single-let commercial building, net operating income SAR 310,000, price SAR 4,000,000.
- Total price SAR 14,700,000, with acquisition costs assumed at 7 per cent, or SAR 1,029,000.
- A single portfolio facility of SAR 8,000,000 at an assumed all-in cost of 6.5 per cent, giving service of SAR 520,000.
- Fixed costs continuing at an empty Asset C assumed at SAR 70,000 per year.
Step 1: Build the portfolio statement
SAR 420,000 plus SAR 290,000 plus SAR 310,000 equals SAR 1,020,000 of net operating income. Capital committed is SAR 14,700,000 plus SAR 1,029,000, or SAR 15,729,000.
Portfolio net yield on total capital is about 6.49 per cent, against about 6.94 per cent on price alone. The difference is the acquisition cost, paid three times rather than once, which is one of the real costs of assembling a portfolio in small pieces.
Step 2: Compare the asset yields
Asset A yields about 6.46 per cent on price, Asset B about 6.90 per cent and Asset C about 7.75 per cent.
Asset C carries the highest yield and the most concentrated risk, since one tenant provides all of its income. The blended figure conceals that, which is why a portfolio statement should always sit beside the asset-level detail rather than replacing it.
Step 3: Lose the single tenant at Asset C
Asset C income becomes zero while SAR 70,000 of fixed costs continue, so it contributes negative SAR 70,000. Portfolio net operating income becomes SAR 420,000 plus SAR 290,000 less SAR 70,000, or SAR 640,000.
A single lease event removes about 37 per cent of portfolio income. Diversification across three assets did not help here, because the loss was concentrated in one indivisible income stream.
Step 4: Lose the same amount of income spread across units
At Asset A, two of twelve units empty for six months at an average SAR 46,667 per unit per year removes about SAR 46,667, taking Asset A to SAR 373,333 and the portfolio to SAR 973,333.
Portfolio income falls by under 5 per cent. The same type of event, a tenant leaving, produces a loss of 37 per cent in one place and under 5 per cent in another, entirely because of how the income is divided.
Step 5: Cover under each case
Base cover is SAR 1,020,000 divided by SAR 520,000, about 1.96 times. With Asset C empty it becomes SAR 640,000 divided by SAR 520,000, about 1.23 times. With the spread voids at Asset A it is about 1.87 times.
The single facility absorbs the spread voids comfortably and is strained by the single-tenant void. The portfolio has one break point, and it is set by its least divisible income stream rather than by its average.
Step 6: What the debt structure decides
If instead each asset carried its own facility, with Asset C borrowing SAR 2,200,000 at service of SAR 143,000, then Asset C alone fails its cover test while Assets A and B continue unaffected at cover of about 1.9 times and 2.0 times on their own facilities.
A single cross-collateralised facility usually buys a better rate and transmits every problem across the whole portfolio. Separate facilities cost more and contain a failure within one asset. That is a structural choice, not an administrative one.
What changes the answer
- Re-letting Asset C within six months rather than twelve halves the income loss and lifts portfolio cover to about 1.60 times for the year.
- Reducing the portfolio facility to SAR 6,500,000 lowers service to about SAR 422,500 and raises stressed cover with Asset C empty to about 1.51 times.
- Adding a fourth multi-let asset of similar size reduces Asset C's share of portfolio income and therefore its ability to breach the covenant alone.
- Management cost per asset falls as the portfolio grows, so a fourth asset improves the blended cost ratio even at an identical gross yield.
- Acquisition costs of 7 per cent paid on three separate purchases consume about SAR 1,029,000 that a single larger asset would have incurred once.
What the numbers tell you
- Diversification protects against frequent small events and does little against one indivisible income stream.
- The portfolio break point is set by its least divisible asset, not by its average yield.
- Acquisition costs paid repeatedly on small purchases are a genuine drag on a portfolio built in pieces.
- A cross-collateralised facility usually prices better and spreads every problem across the whole holding.
- Always keep asset-level statements beside the portfolio statement, because the blended figure hides exactly the concentration that matters.

Frequently Asked Questions
Does owning several rental properties reduce risk?
It reduces exposure to frequent small events such as individual voids and arrears, because those average out across more units. It does little against a concentrated income stream, since losing one tenant who provides a third of portfolio income is a large loss however many buildings you own. What matters is how divisible the income is, not how many title deeds you hold.
Should I take one loan across a property portfolio or separate loans?
A single cross-collateralised facility usually prices better and simplifies administration, and it transmits a problem at one asset to the whole portfolio through shared covenants. Separate facilities cost more and contain a failure within one asset. Decide it as a risk question, comparing the pricing benefit against what a single breach would reach, and have the documents reviewed by a licensed legal adviser.
How do portfolio costs differ from single asset costs?
Management, reporting, accounting and compliance costs do not scale proportionally, so cost per asset usually falls as a portfolio grows. Acquisition costs move the other way, since they are paid in full on every purchase, which makes a portfolio assembled from several small buildings more expensive to build than one larger asset of the same total value.
How should a small property portfolio be reported?
With both views side by side: a portfolio statement for the blended return, cover and distributable cash, and asset-level statements showing income concentration, expiry profile and capital schedule for each building. The portfolio view supports the financing and distribution decisions, while the asset view is where the risk that matters actually lives.
