Sizing a Capital Expenditure Reserve From a Saudi Building's Condition

Sizing a Capital Expenditure Reserve From a Saudi Building's Condition

Domira Team December 17, 2025 7 min read

How to turn a condition survey of a Saudi building into a dated capital expenditure schedule and a reserve you actually fund, instead of a flat percentage of rent.

A capital expenditure reserve is money set aside for items that wear out and must be replaced rather than maintained: lifts, pumps, chillers, roofing, risers, kitchens and bathrooms. Sizing it as a flat percentage of rent is convenient and almost always wrong, because the need is driven by the age and condition of specific equipment, not by how much rent the building happens to produce. The route below builds the reserve from the building itself.

Before stage one

This exercise needs access to the plant, not just the lobby, and it needs someone who can tell the difference between an item that is tired and an item that is finished. Arrange a technical inspection that includes the roof, the plant room, the tank and pump arrangement, the electrical distribution and at least two units in different conditions before you commit to a number.

  • A technical condition survey covering structure, envelope, mechanical, electrical and plumbing systems.
  • Nameplate data and installation dates for the lifts, pumps, cooling plant and electrical switchgear.
  • Service and repair history for each major item, or a clear note that none exists.
  • Agreement on who pays for the survey and who receives the report, so you can rely on it.
  • A view on your intended holding period, because the schedule is only meaningful against a time horizon.

Stage 1: Inventory the capital items

List every component whose eventual replacement is a capital event rather than a repair. For a mid-sized residential block that typically means lifts and their controllers, water pumps and booster sets, tanks, cooling plant or split unit populations, the electrical distribution board and risers, the roof waterproofing, the facade coating or cladding, external joinery, the car park surface, fire detection and suppression, and the kitchens and bathrooms unit by unit. Record quantity, location and make.

  • Deliverable: A component inventory with quantities and locations, one line per replaceable item.
  • Owner: Technical surveyor instructed by the buyer.
  • Approval gate: Nothing on the survey's observation list is missing from the inventory.

Stage 2: Establish remaining life, not nominal life

Published service lives describe equipment that was installed correctly and serviced as intended. Judge each item on what you can see: has the pump been rebuilt, is the lift controller still supported, is the roof patched in several places, has the switchgear been modified by successive contractors? Remaining life is a judgement about this item in this building in this climate, and the surveyor should give a range rather than a single year.

  • Deliverable: A remaining life range for each component, with the reasoning recorded.
  • Owner: Surveyor, with the buyer challenging anything that looks generous.
  • Approval gate: Every item at or beyond the end of its range is flagged for the first two years of the schedule.

Stage 3: Price replacement with the real cost of access

The cost of replacing a component is rarely the cost of the component. Craning a chiller onto a roof, taking a lift out of service in an occupied building, working around tenants, making good finishes afterwards and disposing of the old equipment all add to the bill. Ask a contractor to price the work as it would have to be done in an occupied building, and keep a separate allowance for making good.

  • Deliverable: A replacement cost per component including access, disruption and making good.
  • Owner: Buyer with quotations from relevant trades.
  • Approval gate: No cost is carried forward from a supplier list price without an installation and access allowance.

Stage 4: Place each item on a dated schedule

Spread the inventory across the years of your intended hold and a little beyond, placing each item at the earlier end of its remaining life range where failure would be disruptive and at the later end where it would not. The output is a lumpy profile, because real buildings do not spend evenly. Resist the temptation to smooth it: the lumps are the information, since they tell you which years carry a demand on cash.

  • Deliverable: A year-by-year capital schedule across the holding period, with totals per year.
  • Owner: Buyer.
  • Approval gate: The schedule covers the whole hold plus the year after, so an exit buyer sees what is coming.

Stage 5: Convert the schedule into an annual reserve

Divide the total of the schedule over the holding period by the number of years to get an average annual reserve, then compare that figure against the lumpy profile. Where a single early year exceeds the average by a wide margin, you need either an opening reserve funded at purchase or a facility available for that year. The reserve is a funding plan, not an accounting entry, so decide where the money will actually sit.

  • Deliverable: An annual reserve figure plus an opening reserve where the early years demand it.
  • Owner: Buyer, with any co-investors informed before completion.
  • Approval gate: The largest single year in the schedule has an identified source of funds.

Stage 6: Separate the schedule from operating maintenance

Walk the operating cost schedule and the capital schedule side by side, and remove anything that appears in both. Servicing a lift is operating; replacing its motor is capital. Repainting a unit between tenancies is a re-letting cost; refitting its bathroom is capital. The distinction matters because net operating income excludes capital items, so double counting depresses the value of the asset while single counting inflates the cash you expect.

  • Deliverable: Two reconciled schedules with a short note on each borderline item and where it sits.
  • Owner: Buyer.
  • Approval gate: Each borderline item appears in exactly one schedule and the choice is documented.

Stage 7: Reflect the schedule in the price and the deal

A building that needs a lift, a roof and a pump set in the first three years is worth less than one that does not, by an amount that is calculable rather than arguable. Decide how to handle it: a price reduction, a retention held at completion, the seller carrying out the work before transfer, or your acceptance of the spend with a lower offer. Each route has different risk, and a retention only helps if the mechanism is drafted properly.

  • Deliverable: A negotiating position quantified from the schedule, with the preferred mechanism chosen.
  • Owner: Buyer with legal support on the mechanism.
  • Approval gate: The commercial treatment of the early capital spend is settled before exchange rather than after.

Stage 8: Review and re-base the schedule annually

Once you own the asset, the schedule becomes a live document. Each year, record what you actually spent, update remaining life for items that were serviced or failed, and re-price the items still ahead using current quotations. Over a hold of several years this record becomes one of the most valuable documents in the file, because it replaces a buyer's guesswork with your measured history.

  • Deliverable: An annually updated capital schedule with actual spend recorded against each line.
  • Owner: Asset manager or the owner personally.
  • Approval gate: The updated schedule is reviewed before the annual distribution is set, not after.

Handovers between stages

The weak point is the gap between the surveyor's report and the financial model. Surveyors write observations in prose, modellers need dated lines with costs, and the translation is where items go missing. Close it by giving the surveyor your schedule template at the point of instruction, so the report arrives in the shape the model needs, and by having the surveyor review the completed schedule to confirm that nothing was lost or softened in transit.

How you know it is finished

The reserve is properly sized when every major component has a remaining life range, a priced replacement, a year in the schedule and an identified source of funds, and when the whole schedule reconciles against the operating cost statement without overlap. Figures for materials, plant and installation move with market conditions and must be re-quoted at the time you commit, and anything with a regulatory dimension, such as fire systems or lift compliance, should be confirmed against the current requirements rather than the ones that applied when the equipment was installed.

The investment decision stays yours, and so does the advice of your licensed tax and legal advisers.

Frequently Asked Questions

How much should I budget for capital expenditure on a rental building?

Build it from the components rather than from a percentage. Inventory the replaceable items, establish remaining life for each, price replacement including access and making good, and place them on a dated schedule across your hold. The annual reserve then falls out of that schedule. A percentage of rent produces a number that is unconnected to whether your lift is twenty years old or two.

What is the difference between capital expenditure and maintenance on a property?

Maintenance keeps an existing component working and recurs: servicing, cleaning, minor repairs, consumables. Capital expenditure replaces or materially upgrades a component and happens once in its life: a new lift motor, new roof waterproofing, a refitted bathroom. The distinction matters because net operating income includes maintenance and excludes capital items, so misclassifying one distorts both your value and your cash planning.

Should the seller pay for capital works identified during due diligence?

It is a commercial negotiation informed by a quantified schedule. The common routes are a price reduction, a retention from the purchase price released when the work is done, the seller completing the work before transfer, or the buyer accepting the spend knowingly. Which one suits depends on how urgent the work is and how much you trust the delivery. Any retention or escrow mechanism should be drafted by a licensed legal adviser.
