An illustrative calculation showing how to compare planned supply with demand in a Saudi district, and why the timing of completions matters as much as the total.
A supply pipeline tells you how much competing space will arrive and when; compared with realistic demand, it shows whether rents are likely to hold. In Saudi cities where large master-planned communities and government-backed developments are adding supply, reading the pipeline is often more important than reading headline demand. The example below uses invented figures to show the method, not to describe any real district.
The situation
An investor is considering buying apartments to let in a growing district of a large Saudi city. Brokers report strong demand, but several projects are under construction nearby. The investor wants to estimate whether new supply will outpace demand over the next three years.
Assumptions (illustrative)
- Existing occupied units in the district: 8,000 (illustrative).
- Existing vacant units: 400 (illustrative).
- Pipeline: 1,500 units due in year one, 2,500 in year two, 1,000 in year three (illustrative).
- Assumed share of pipeline that completes on time: 70 per cent, with the rest delayed by one year.
- Assumed new household demand in the district: 1,600 units per year.
- Healthy vacancy assumed at about 5 per cent of total stock.
Step 1: Starting vacancy
400 divided by (8,000 plus 400) equals 400 divided by 8,400, about 4.8 per cent.
The market starts close to a healthy level, so rents are not being pushed up by extreme scarcity.
Step 2: Adjust completions for delay
Year one: 1,500 multiplied by 70 per cent equals 1,050. Year two: 2,500 multiplied by 70 per cent equals 1,750, plus 450 delayed from year one, equals 2,200. Year three: 1,000 multiplied by 70 per cent equals 700, plus 750 delayed from year two, equals 1,450.
Delays shift supply into later years; the total stays the same but the peak moves.
Step 3: Compare with demand each year
Year one: 1,050 new units against 1,600 demand, a shortfall of 550. Year two: 2,200 against 1,600, a surplus of 600. Year three: 1,450 against 1,600, a shortfall of 150.
The district tightens in year one, loosens sharply in year two, and roughly balances in year three.
Step 4: Track vacant units
Start 400; year one 400 minus 550 cannot fall below zero in practice, so vacancy is near 0 and 150 households remain unserved; year two 0 plus 600 minus 150 unserved demand equals 450 vacant; year three 450 minus 150 equals 300 vacant.
Pent-up demand from year one absorbs part of the year two surplus, which softens the dip.
Step 5: Vacancy rate in year two
Total stock after year two is 8,400 plus 1,050 plus 2,200 equals 11,650; 450 divided by 11,650 is about 3.9 per cent.
Even the year of heaviest supply stays near a healthy vacancy level under these assumptions.
Step 6: Test weaker demand
If demand is 1,200 a year instead of 1,600, year one leaves 400 plus 1,050 minus 1,200 equals 250 vacant; year two adds 2,200 minus 1,200, so vacancy reaches 250 plus 1,000 equals 1,250, and 1,250 divided by 11,650 is about 10.7 per cent.
Under weaker demand, the district moves into clear oversupply in year two, and rents are likely to soften for the investor.
What changes the answer
- The demand estimate matters more than any other input; small changes move the district between shortage and surplus.
- Delays can relieve pressure in a given year but create a later wave of completions.
- Units that are sold to owner occupiers compete less directly with rental stock than units bought by investors.
- New transport links, such as metro stations, can shift demand between districts and change absorption.
- Rent restraint rules, like the measures introduced in Riyadh in 2025, affect how quickly rents can adjust in tight years.
What the numbers tell you
- Ask for the timing of completions, not only the total units planned.
- Build demand from household and employment data rather than from broker enthusiasm.
- Check which pipeline projects are actually under construction on site.
- Plan the purchase so that your units are not completing in the same year as the largest wave of supply.
- Re-run the numbers each year as projects start, pause or complete.

Frequently Asked Questions
How can I find out how many new homes are being built in Riyadh?
Start with official sources: REGA and the Housing Program publish information on housing supply and programmes, municipalities approve permits, and large developers and national housing companies announce projects. Complement this with site visits and conversations with brokers and contractors, because projects on paper and projects on site can differ considerably. Record the status and expected completion of each.
Is there a risk of oversupply in Saudi real estate?
Any market that is adding large volumes of new stock can face local oversupply in particular districts and years, even if overall demand is strong. The risk depends on the timing of completions, the type of units and how many are aimed at renters. Reading the pipeline district by district is more useful than asking whether the whole market is oversupplied.
What is an absorption rate in property?
An absorption rate is the pace at which available units in a market are leased or sold over a period, often compared with the pace at which new units arrive. If new supply arrives faster than it is absorbed, vacancy rises and prices or rents tend to soften. It is a simple but useful way to compare pipeline and demand.
