Scenario planning for a multi-site portfolio starts with the expiration ladder
Portfolio scenarios fail because the model says act now and the lease says wait four years. Plan against the expiration ladder, not the spreadsheet.

Real estate scenario planning is the practice of modelling alternative futures for a portfolio and comparing them: keep, consolidate, exit, relocate, expand, or renegotiate at each location, and what each path costs over a defined horizon. It fails more often than other planning disciplines because every move waits on a contractual window, and most of those windows are not open.
Why the lease, not the model, sets the timetable
Consider a portfolio of two hundred leased locations on terms averaging ten years. In any given year, roughly fifteen to twenty-five leases reach an expiration or an option window. Those locations are the year’s action set. A useful plan ranks by value at stake and then intersects that ranking with the calendar; the intersection is the plan.
The five moves and what each one requires
| Move | What governs the window | Lead time that actually binds |
|---|---|---|
| Exit at expiration | Notice deadline, often 9 to 12 months before expiry | Decision and approval must finish before the notice date |
| Consolidate into another site | Both leases, and any expansion right at the receiver | Whichever site’s window is tighter, plus fit-out |
| Renegotiate in place | The option notice window, which lapses silently | Market evidence assembled before you open the conversation |
| Expand in place | The option’s notice period and the landlord’s own timing | Landlord’s availability, which you do not control |
| Relocate | Notice deadline, plus permitting and construction | Buildout and permitting, usually the longest pole by far |
A relocation that completes on the day a lease expires had to begin, in practice, more than a year earlier. Missing a notice date can trigger an automatic renewal, forfeit a negotiated option, or drop you into holdover at a substantial premium, which is what keeps critical dates and notices the work behind the plan.
What a scenario needs beyond the economics
- Lease constraints: exclusive use clauses, radius restrictions, co-tenancy provisions, and assignment or sublease limits
- Physical feasibility: whether the receiving location can actually absorb the operation, a drawings question that drifts
- Licences and permits: many attach to a location rather than the company, and the re-application clock may exceed the window
- Remaining improvement basis: the undepreciated balance written off on exit, per
leasehold improvement depreciation. Market conditions at the window round out the list. A scenario missing any of these is a financial exercise rather than a plan, which is the substance of portfolio strategy.
Sequencing, which is where plans actually break
- 01Build the ladder first: every location, expiration, option, and notice deadline in one schedule
- 02Rank by value at stake, not by performance
- 03Work backwards from each notice date, subtracting analysis time, approval cycle, and any permitting and buildout period
- 04Resolve the dependencies: consolidations couple two locations, so the constraint is the tighter window
- 05Re-run the ladder annually, and after any event that changes it
Most plans break at step three, when the analysis is scheduled against the expiration date and the notice date passes while the business case is still circulating. The single consolidation decision at one location is tractable; doing it across two hundred locations against two hundred different calendars is the part that requires a system.
CoreNet Global’s public summary of its portfolio optimization work describes the current emphasis as "space reduction, the shedding of excess or inefficient space to cut costs, as well as ongoing efforts to reposition existing space," noting that space utilization has displaced traditional occupancy analysis.

Frequently asked questions
What is scenario planning in commercial real estate?
- Modelling alternative futures for a portfolio and comparing them: what each location costs and contributes under keep, consolidate, exit, relocate, expand, or renegotiate, over a defined horizon. Execution is gated by lease events, so the plan has to be built against the expiration and option schedule.
How far ahead should a portfolio plan be built?
- Far enough to clear the longest lead time in the set of moves you are contemplating. For exits and renegotiations, that is the notice deadline plus your internal approval cycle. For relocations, permitting and construction usually push the effective start well over a year before expiry.
What is a lease expiration ladder?
- A schedule of every location’s expiration, renewal and termination options, and associated notice deadlines, laid out so you can see how much of the portfolio becomes actionable in each future period. It is the foundation of portfolio planning and the artefact most often missing or out of date.
What happens if a notice deadline is missed?
- It depends on the clause. Common outcomes are an automatic renewal for a further term, forfeiture of a negotiated option, or holdover, where rent typically resets to a substantial premium.
Should scenario planning be run by real estate or finance?
- Both. Finance owns the model and the approval threshold; real estate owns the constraints that decide whether a modelled move is available. The failure mode is a financially sound plan that nobody checked against lease restrictions, licences, or physical feasibility, discovered only after approval.

Reading portfolio performance in real time so the call to invest, hold, or exit is grounded in evidence.
What is space management software, and how does it connect to occupancy cost
Booking a room and measuring how it is actually used are two different questions. Neither means anything for a portfolio decision until it is tied to cost.
What is site selection software, and why one-time studies are losing ground
A market that looks open on paper often is not. Site selection software scores candidate locations continuously instead of once, before a lease gets signed.
