Saudi Property Lease Expiry: A Rent-Weighted Example

A rent-weighted lease-expiry calculation shows how much remaining lease time sits behind each share of a property's contracted rental income. It helps an investor distinguish a portfolio with many long leases from one whose largest income source expires soon. Calculate the average alongside a dated expiry schedule: a single number cannot show every point at which rental income may change.

This is an investment-analysis method, with an original hypothetical example in Saudi riyals. It is not a forecast of Saudi rents, a lender's minimum requirement or a guarantee that a tenant will keep paying. Begin with verified lease data, define the measurement date and explain which rental amounts and end dates enter the calculation.

Read the definition before comparing the number

Saudi property reports use weighted lease-duration measures. For example, SEDCO Capital REIT's December 2025 annual report presents weighted average lease expiry, or WALE, alongside other portfolio information. That illustrates the metric's use in Saudi investment reporting; the report's historical portfolio is separate from the invented example below.

Definitions still matter. Landsec's results for the half year ended 30 September 2025, page 54, define their mean lease term using rent weights and the earlier of tenant break or expiry, with short-term leases excluded. This is a disclosed UK reporting convention, rather than a Saudi legal rule or a definition automatically applicable to every fund.

For your analysis, identify whether the stated figure is weighted by rent or floor area, whether it ends at contractual expiry or an earlier relevant break, and whether vacant units are excluded. Two identical-looking averages can describe different sets of leases. Comparing them without the footnotes may obscure the income exposure you intended to measure.

Build an original three-lease example

Assume a measurement date of 3 October 2026 and three fictional leases. Their hypothetical annual contracted rents are SAR 50,000, SAR 30,000 and SAR 20,000. For this first calculation, their remaining terms to the selected expiry dates are exactly one, three and five years respectively. No early breaks, rent changes, arrears or concessions enter this simplified scenario.

Multiply each annual rent by its remaining term, add the products and divide by total annual rent. The numerator is 50,000 × 1 + 30,000 × 3 + 20,000 × 5 = 240,000 SAR-years. Dividing by SAR 100,000 gives a rent-weighted remaining term of 2.4 years. Currency cancels, so the answer is time, not a percentage return.

The unweighted average would be (1 + 3 + 5) ÷ 3 = three years. That treats every lease as equally important even though Lease A supplies half the annual contracted rent. The weighted result is shorter because the largest income contribution has the earliest expiry. Neither calculation is inherently incorrect; they answer different questions, and the label must say which one you used.

Put the expiry schedule beside the average

In the example, half the annual contracted rent reaches its selected expiry date one year after the measurement date. A further 30% reaches its date after three years, and the final 20% after five. The 2.4-year average does not mean every lease expires at that point, or that the portfolio retains all income until then.

Show the actual dates when using real data, and group them into useful intervals such as the next twelve months and subsequent annual periods. Keep the weighting denominator visible. A timeline based on current contracted rent should not silently substitute an assumed future market rent when it reaches an expiry date.

Read the schedule alongside our property concentration-risk analysis. Several leases may share a tenant or depend on the same local demand. Spreading expiry dates can reduce one kind of timing concentration while leaving those other exposures intact. Record both relationships rather than declaring a portfolio diversified from the average alone.

Test an earlier break as a separate scenario

Now suppose, solely for illustration, that Lease B has a relevant tenant-break date eighteen months from the measurement date. Keep annual rent weights unchanged and replace its three-year term with 1.5 years in a separate calculation. The numerator becomes 50,000 × 1 + 30,000 × 1.5 + 20,000 × 5 = 195,000 SAR-years. The resulting average is 1.95 years.

Label the first result as the selected expiry-date calculation and the second as the earlier-break scenario. Whether a clause permits a break, what conditions apply and which date is relevant require review of the actual documents and applicable rules. Arithmetic cannot resolve those questions or establish that the tenant will exercise the option.

The two results also cannot predict reletting time. An earlier possible end date is an analytical input; the subsequent void period and replacement rent are separate assumptions. Our rental turnover-cost guide explains why the period between tenancies can involve costs as well as missing income.

Separate contracted rent from collected cash

A remaining-term average can look comfortable while cash receipts are irregular. Keep annual contracted rent, rent actually collected, payment timing and operating costs in separate fields. Disclose any concessions or unusual rent structure rather than forcing them into a single unexplained annual amount. See our effective-rent comparison for a different question: what the agreed economic rent means after stated concessions.

Vacant space needs its own record. A vacant unit has no current contracted rent to contribute to this example's denominator; excluding it does not make its ownership costs disappear. Present occupied and vacant exposure separately so an average calculated only on paying leases is not mistaken for a description of the whole building's cash position.

Finally, connect the expiry schedule to the monthly rental cash view. A large annual rental payment and a near-term expiry can affect different months. Useful analysis shows the amounts and dates together instead of treating the weighted average as a substitute for a cash forecast.

Keep a calculation that another reader can reproduce

• Record the measurement date, lease identifiers and the source of each annual rent.
• State the weighting basis, selected end dates, treatment of breaks and any exclusions.
• Preserve the lease-level products, total annual rent and unrounded average before presentation rounding.
• Add the dated expiry distribution and a separate vacancy and collection summary.

Update the calculation when its inputs change, while keeping earlier versions for comparison. Use it to locate the next material income decision and the assumptions that need attention. A reproducible average plus an honest schedule is more useful than choosing an impressive duration and leaving the underlying leases unexplained.
