For Dubai office investment, the direct question is which vacancy assumptions need evidence. The answer begins with the specific unit, its leasing history and its realistic tenant pool, not a broad claim about a district.
Key Takeaways
| Investor question | Evidence to look for |
|---|---|
| What supports the occupancy assumption? | Executed leases, dated building leasing records and verified unit details. |
| Does the rent forecast reflect income received? | Separate physical vacancy, rent-free periods, arrears and under-rented space. |
| Can this space reach the intended tenant? | Evidence of tenant demand, permitted use, fit-out requirements and usable workstations. |
| How should location affect the forecast? | Compare like-for-like buildings and units, then use Dubai area guidance as context, not proof of a unit’s prospects. |
| What should a downside scenario include? | Longer leasing time, weaker rent, tenant incentives, operating costs and commercial finance. |
| How can we keep the decision auditable? | Record each assumption, its source, date, scope and effect on cash flow. |
Separate physical vacancy from lost rental income
Physical vacancy describes space that has no tenant in occupation. Economic vacancy captures income lost even when an office looks occupied, including rent-free periods, unpaid rent and leases below the rent assumed in the model.
Keep these effects visible as separate inputs. A single vacancy percentage can hide the reason income falls short and make it harder to see whether the issue comes from empty space, incentives or collection.
- Physical vacancy: the unit is empty and not producing rent.
- Rent-free time: a tenant has a lease, but the agreed incentive delays or reduces rent receipts.
- Collection shortfall: rent due does not arrive in full or on time.
- Under-rented occupation: a tenant occupies the unit, but the contracted rent falls below the model’s assumption.
Ask for executed leases and amendments, a dated rent roll, payment records and a schedule of vacant or marketed units. A leasing summary without dates, areas and lease terms cannot show whether the evidence applies to the unit you are assessing.
Our office investment service covers commercial assets, but an investment decision still needs property-specific leasing proof. The building’s marketing description is not a substitute for a unit’s rental record.
Rank leasing evidence before relying on a vacancy rate
Evidence has a hierarchy. Start with the closest match to the asset, then use wider market information to test whether the unit-specific case makes sense.
- Executed leases and amendments: compare the unit’s signed terms, rent commencement, incentives, expiry and renewal provisions with the model.
- Building leasing records: request dated records showing which units were available, marketed, leased or occupied, with their areas and key terms.
- Verified unit information: inspect the space and review its floor plan, condition, access and intended use.
- Comparable leases: use evidence from similar offices, adjusting for grade, fitted condition, unit size, lease terms and the date of each transaction.
- District reports: use broad market information as context. It cannot prove the leasing prospects of a particular floor or office.
Record the source and date alongside every input. A comparison from a different period, building grade or unit type may still be informative, but the difference needs to be explicit rather than buried inside a blended vacancy figure.
Our location guidance and Dubai investment guide can help frame area and asset choices. For vacancy underwriting, we still want leasing evidence that matches the building, unit and lease structure.
Use district conditions as context, not as proof
Location affects the tenant pool, access, nearby services and competition from other offices. Yet a district label does not establish that a specific unit can attract the occupier assumed in a forecast.
Compare offices within a relevant catchment, then account for building grade, transport access, parking, floor level, unit layout and the availability of competing space. A small fitted office may appeal to a different tenant than a large shell-and-core floor in the same area.
Office supply also belongs in the scenario, but it should not replace direct leasing evidence.
Use market context to ask sharper questions: which competing buildings offer comparable space, how soon could they lease, and does the intended tenant value this unit’s features? Our overview of Dubai areas for investment offers wider location context, not a substitute for building-level records.

Tenant demand is not a general statement about business growth. Identify the occupier the unit could realistically serve, then test the requirements that affect whether that tenant can take the space and operate there.
Check permitted use against the intended business activity, building rules and relevant approvals. Review access arrangements, operating hours, parking, services and layout against the tenant’s working pattern. A unit that cannot support the required activity should not count as lettable space for that tenant in the forecast.
Compare usable workstations and functional layout, not just price per square foot. Fit-out condition also changes the leasing proposition: a ready-to-use office may shorten the work a tenant needs to complete, while a space requiring substantial work may need more time, cost or landlord contribution before occupation.
- Match the permitted use and building requirements to the target occupier’s activity.
- Check the floor plan, usable area, access and services against the proposed work pattern.
- Confirm who pays for fit-out, what approvals apply and how the work affects the lease-up period.
- Assess tenant quality through the proposed lease, payment arrangements and capacity to meet obligations.
Questions about a project and its delivery can be framed with our developer information and off-plan guide. For a future office, include the handover condition and approvals in the lease-up plan; do not model immediate rent simply because the asset is expected to be delivered.
Off-plan offices carry a different timing question from completed units. Our off-plan properties in Dubai page and The Yards Plaza case provide project context, while leasing assumptions still require their own evidence.
Connect vacancy assumptions to cash flow and break-even
Build the income forecast from lease-up timing, rent commencement, incentives, expected collections and expiry dates. Model lease-up period and tenant turnover separately from physical vacancy so that a delayed letting does not disappear inside an annual average.
Show each material cost alongside weaker occupancy: fit-out and fit-out approval, leasing fees, rent-free incentives, service charges, utilities, maintenance, insurance, management and commercial finance. Include the timing of these costs, since cash may leave the account before a tenant starts paying.
For a worked payment example, M&M’s The Yards Plaza case lists a starting price of AED 2.85M and a 40/60 payment plan:
- AED 2,850,000 × 40% = AED 1,140,000.
- AED 2,850,000 × 60% = AED 1,710,000.
- AED 1,140,000 + AED 1,710,000 = AED 2,850,000.
This illustrates payment timing, not rental income or vacancy performance. An investment case still needs to show when leasing costs arise, when rent begins and whether available funding can cover the gap.
Calculate break-even against cash expenses and debt obligations, not just forecast profit. Compare the expected case with a downside scenario that combines slower leasing, weaker rent, additional incentives and the operating costs that continue while the unit is empty.
For an income review, our rental yields and costs guide offers a structure, while our Dubai property tax guide addresses a separate part of the ownership assessment. Keep investor residency objectives distinct from tenant income assumptions; our Dubai Golden Visa guide covers that separate consideration.
Keep a clear audit trail for every assumption
A strong investment case lets another person trace each input to its evidence. Record the figure used, the source document, its date, the relevant building or unit, the adjustment made and the model cell it affects.
Keep source documents with the model: executed lease evidence, leasing schedules, inspection notes, floor plans, fit-out estimates, operating-cost schedules and finance terms. Note whether a figure describes the whole building, a particular unit or a broader area.
We approach an office case as an advisory decision, not a sales pitch. No noise. Just real leasing evidence, visible assumptions and a downside scenario that shows how cash flow changes when the letting takes longer.
For more material to organise an investment review, use our investor resources. A written audit trail helps the investor, adviser and finance provider discuss the same assumptions rather than relying on different versions of the forecast.
Dubai office investment vacancy assumptions need evidence tied to the actual unit, its tenant pool and its lease terms. Separate empty space from rent-free time, collection shortfalls and under-rented occupation, then connect each input to costs, cash flow and break-even.
District context can inform the case, but it cannot prove a specific office will lease. We look for real leasing records, verified permitted use, realistic fit-out and operating costs, and a downside scenario that makes the funding need visible.
What documents can substantiate an occupancy assumption for a specific Dubai office?
Use executed leases and amendments, a dated rent roll, payment records, vacant-unit schedules and building leasing records. A unit inspection and current floor plan help confirm that the recorded space matches the asset being modelled.
How should I account for lease renewals when forecasting office vacancy?
Show each material expiry separately and assign a renewal case only where the tenant’s lease position and known intentions support it. Model the alternative case with a defined period for negotiation, vacancy and reletting.
Can a tenant letter of intent support projected office rent?
A letter of intent can indicate interest, but it is not the same as an executed lease or rent received. Track its status, conditions and proposed terms separately, and keep the base case distinct from income that depends on an uncompleted negotiation.
What should I do if the office is leased to one large tenant?
Model the lease expiry and renewal exposure as a concentrated risk rather than treating the building’s overall occupancy as sufficient comfort. Test the cost and time needed to divide, adapt or remarket the space if that tenant leaves.
How do shared or flexible offices change a vacancy assessment?
Review income at the level of the underlying space and the agreements that generate receipts, not just the operator’s reported occupancy. Include management, fit-out and operating obligations that continue even when individual desks or rooms are unused.
When should I pause an office investment decision?
Pause when the permitted use, leasing history or cost responsibility cannot be reconciled with the income case, or when the downside cash requirement has no credible funding plan. The next step is to obtain the missing property-specific evidence and rerun the model before relying on its projected return.
