The question of how to treat off-market options fairly alongside listed buildings in a shortlist is one that sits at the intersection of adviser judgment, process discipline, and client trust. When one candidate property has a marketed rent, floor plan, and inspection history, and another exists only as a landlord conversation or a portfolio relationship, the comparison feels uneven from the start. Getting the evaluation right requires deliberate methodology — not just good instincts.
Why Off-Market Properties Create Scoring Distortions
A listed building arrives in a shortlist with a dense information packet: asking rent, NLA, lease term, incentive structure, inspection access, and often floor plans. An off-market option typically arrives with a name, a rough size, an indicative rent, and a conversation. The gap in data volume does not reflect a gap in the property's merit, but it can distort any scoring framework that rewards data richness over property quality.
The most common distortion is penalising the off-market option for missing information it cannot yet provide. A scoring matrix that assigns a low mark to any field lacking a confirmed figure will mechanically disadvantage the off-market candidate, even if the adviser believes it is a genuinely strong option. That mechanical disadvantage then skews the recommendation in ways the client may not understand.
A second distortion runs the other way. Some advisers overweight off-market options because sourcing them feels like added value. The relationship that surfaced the lead, the exclusivity implied by its unlisted status, and the narrative of a hidden gem can all create a bias toward recommending it before the numbers justify that recommendation. Both distortions are real, and a sound methodology must guard against each.
Establishing a Level Information Baseline Before Scoring Begins
The right response to unequal data is not to score immediately but to establish a baseline of comparable information across all candidates before any formal evaluation begins. That baseline does not need to be exhaustive, but it must cover the variables that drive the final decision: rentable area, gross-up factor, term flexibility, effective rent, fit-out allowance, and critical access or operational constraints.
For the listed properties, most of that information is already available, though it still needs verification. Asking rent is not effective rent. Net lettable area on a marketing brochure often reflects a different measurement standard than the building's actual lease schedule. Before treating listed information as confirmed, an adviser should cross-reference the floor plans, check the measurement methodology, and understand how the incentive structure translates into net cost over the lease term.
For the off-market option, the baseline requires more active information gathering. The adviser should request a term sheet, an indicative head-of-terms document, or at minimum a written summary of the landlord's position. Without something in writing, the off-market candidate is not comparable — it is a lead, and leads belong in the pipeline, not the shortlist.
Once each candidate has a written summary covering the same core variables, the comparison becomes structurally fair. A missing figure is then recorded as "not yet provided" rather than zero, which removes the penalty without inflating the option's apparent quality.
Defining the Criteria Before Seeing the Properties
A principle that applies to all shortlisting work, but carries particular force when off-market options are involved, is that evaluation criteria must be defined before the properties are examined. When criteria are defined after the candidates are assembled, the adviser risks — consciously or not — writing criteria that favour the option they already prefer. This is a known bias in procurement methodology and applies equally to site selection.
The criteria-first discipline is straightforward in practice. At the start of the engagement, the adviser and the client agree on the factors that will drive the decision and their relative weight. Location and accessibility, NLA and divisibility, structural condition, lease flexibility, capital contribution, and car parking ratio are typical primary criteria. Each factor carries a weight that reflects the client's stated priorities, and those weights are locked before any specific property is considered.
Secondary criteria can include energy rating, floor plate efficiency, end-of-trip facilities, and proximity to key staff postcodes. These tend to carry lower weights but can still move a close comparison. The important discipline is that the list is complete and weighted before the shortlist is assembled, so no criterion is added later to favour a candidate that is already in the room.
Assigning Scores With Documented Assumptions
Once the criteria and weights are set and the information baseline is established, scoring can begin. Each property receives a score on each criterion, that score is multiplied by the criterion weight, and the weighted totals are summed to produce a comparable ranking. That is the standard mechanism. The methodology question is how to handle off-market properties where some scores rest on assumptions rather than confirmed data.
The right approach is to score assumptions explicitly. Where a confirmed figure is available, record it and score against it. Where a figure is assumed — for example, the adviser believes the off-market landlord will contribute a fit-out allowance based on market precedent — the score should reflect the assumption, and the assumption should be documented separately alongside the score. The client then knows which parts of the comparison are confirmed and which are contingent.
This assumption-documentation discipline serves a second purpose. If the off-market option proceeds to negotiation and the assumption proves wrong — the landlord declines the expected fit-out contribution, for example — the client can see exactly how the economics shift and can make a fresh decision on that basis. Without the documented assumption, the adviser is explaining a gap that the client did not know existed.
That structured record keeps the basis for each score visible alongside the score itself, which is particularly important when some scores reflect assumptions that have not yet been tested in negotiation.
Calculating Effective Rent Consistently Across Both Property Types
One of the most consequential steps in treating listed and off-market options fairly is ensuring that effective rent is calculated on the same basis for every candidate. Asking rent is the least useful comparison point because it reflects neither the incentive package nor the lease structure. Effective rent — the net cost per square metre per annum after incentives are amortised over the lease term — is the figure that enables an honest comparison.
For listed buildings, effective rent can usually be estimated from the marketing material, adjusted for the adviser's read of the landlord's negotiating position. The face rent, the rent-free period, the fit-out contribution, and the term combine to produce a present-value cost stream, and that cost stream divided by the area and the term produces an effective rent figure. Many advisers use a lease NPV model to do this more precisely, discounting the net rent payments over the lease term using the client's cost of capital.
For the off-market option, the same calculation should be applied to whatever indicative terms the landlord has indicated. If the face rent is indicative only, the effective rent calculation should use the mid-point of the range the landlord has suggested, with a sensitivity table showing how the outcome changes at the low and high ends. That sensitivity table is part of the documented assumptions record and should sit alongside the scoring matrix in the shortlist presentation.
Using that capability consistently across every candidate — listed or off-market — means the economic comparison rests on the same computational logic regardless of how each property entered the process.
Managing the Evidence Trail for Off-Market Candidates
A listed property has a public record. The marketing campaign, the agent's brochure, and the lease or sales terms are part of an observable market at a point in time. When a client asks why a listed building was included in the shortlist, the adviser can point to public evidence. When a client asks why an off-market property was included, the adviser's answer depends entirely on what they have in their own files.
That difference in evidence trail makes file discipline more important for off-market candidates, not less. Every conversation with the landlord or their representative should produce a written record — a follow-up email, a summary of the call, or a copy of the indicative heads-of-terms. Every assumption that drives a score should be in writing. The source of market evidence used to benchmark the off-market rent should be referenced.
The adviser who can show how each score was derived, and what document or conversation supports each assumption, is in a materially stronger position when the client's board asks how the recommendation was formed.
The file also protects the client. If an off-market property is recommended and the transaction proceeds, the evidence trail shows that the selection was based on structured analysis rather than a relationship the client may not have been aware of. That transparency is part of professional practice in commercial real estate advisory.
Handling the Timing Mismatch Between Listed and Off-Market Options
Listed properties have published availability dates. Off-market opportunities often do not. The landlord who is considering releasing space may not be ready to commit to a date, and the adviser managing the engagement faces a timing mismatch: the client's requirement has a deadline, and the off-market option may or may not resolve before that deadline arrives.
The right approach is to treat the off-market option's timing uncertainty as a scored criterion rather than an unresolved variable. The evaluation should include a criterion for certainty of availability, with a confirmed date scoring higher than an indicative date, and an indicative date scoring higher than an uncertain date. This converts the timing risk into a comparable data point rather than leaving it as a qualitative concern that the adviser manages informally.
The timing criterion also informs the negotiation strategy. If the off-market option is the preferred property on most other criteria but has timing uncertainty, the adviser might negotiate a conditional heads-of-terms that preserves the client's position for a defined period while the landlord confirms. That approach is only credible if the adviser has already negotiated something in writing with the listed properties and can demonstrate to the client that they are not simply waiting for the off-market deal to crystallise.
Shortlist Presentation Standards That Apply to Both Property Types
The shortlist document that goes to the client's decision-makers should present every candidate on the same template, regardless of whether it is listed or off-market. The template should include the property address, NLA, effective rent, term, incentive summary, fit-out approach, scoring matrix, and a recommendation note that explains the adviser's view on that specific property's merits and risks.
For off-market candidates, the recommendation note should explicitly flag which figures are confirmed and which are assumed. The note might read: "Face rent indicative at [X] per square metre per annum, subject to formal heads-of-terms. Fit-out contribution assumed at [Y] based on comparable transactions in the same precinct during the last twelve months. Effective rent estimate [Z]." That level of disclosure does not weaken the recommendation; it demonstrates that the adviser has been rigorous about what they know and what they are assuming.
The client's decision-makers should be able to see the full basis for each recommendation, not just the headline scores.
The presentation should also include a risk summary for each candidate, covering the three or four most material risks associated with proceeding. For listed properties, those risks typically include lease-term inflexibility, competition from other tenants, and landlord financial stability. For off-market options, the risks typically include the absence of a formal tender process, the assumption-dependency of the economic analysis, and the possibility that the landlord withdraws if they receive an unexpected approach from another party.
Formalising the Process in a Standard Operating Procedure
The methodology described in this article can be executed ad hoc, but it delivers more consistent results when formalised in a standard operating procedure that the advisory team applies to every engagement involving a mix of listed and off-market candidates. That SOP does not need to be elaborate — a checklist and a standard shortlist template will carry most of the weight.
The SOP checklist should confirm that criteria and weights were agreed with the client before any properties were assessed, that every candidate has a written information baseline, that effective rent has been calculated on the same basis across all candidates, that all off-market assumptions are documented and sourced, and that the shortlist document presents every candidate on the same template. If any item is not checked, the shortlist is not ready to present.
The standard template is the second element. A single template that accommodates both listed and off-market candidates, with dedicated fields for confirmed versus assumed data, enforces the documentation discipline without requiring the adviser to remember it each time. It also makes the shortlist more efficient to produce — the information-gathering stage populates the template, and the template produces the shortlist.
Teams that invest in this kind of process discipline find that the methodology itself becomes a client-facing differentiator. When a client's board asks how the recommendations were formed, the adviser who can show a reproducible process with documented assumptions is in a stronger position than the adviser who is explaining their judgment after the fact.
Maintaining Objectivity When a Relationship Surfaced the Lead
A specific risk that deserves direct treatment is the conflict of interest that can arise when the off-market option was sourced through a relationship the adviser holds with the landlord or vendor. That relationship is not inherently a problem — most off-market opportunities exist precisely because of adviser relationships — but it requires explicit management to maintain the objectivity of the evaluation.
The first management step is disclosure. The client should know, before the shortlist is presented, that the off-market candidate was sourced through a specific adviser relationship and what, if any, fee arrangement exists with the landlord's side of the transaction. Some clients will be entirely comfortable with that arrangement; others will want an independent review of the scoring. Either way, the disclosure is part of professional practice.
The second management step is scoring by a second adviser or reviewer who was not involved in sourcing the lead. That reviewer applies the agreed criteria and weights to the off-market option independently, then compares their scores with the original. Where scores diverge materially, the difference is discussed and a consensus position is documented. This two-step process is more common in institutional transactions but should be considered standard practice whenever the sourcing relationship creates a potential conflict.
Using the Shortlist to Drive Negotiation Strategy, Not Just Property Selection
A shortlist that fairly treats listed and off-market options does more than produce a recommendation. It creates a negotiating platform. When the client approves the shortlist, the ranked properties define the competitive field, and the adviser can use that competition to drive better terms from the preferred landlord — whether the preference is for a listed or off-market property.
The negotiation leverage depends on the client approving at least two properties as acceptable. If the shortlist collapses to a single preferred option too early, the adviser loses the ability to credibly threaten to proceed with an alternative. This is especially important when the off-market option is the preferred property, because the landlord knows there is no competing listed transaction visible in the market. The listed properties in the shortlist are the visible alternatives that give the adviser their negotiating leverage.
That parallel-track discipline is not about bad faith; it protects the client from the risk of a single-track negotiation collapsing.
Reviewing the Shortlist When New Information Arrives
No shortlist is static. As negotiations proceed, new information arrives — a listed landlord confirms they will not negotiate on term, an off-market landlord provides a formal heads-of-terms, a competitor tenant signs on a building the client was considering. Each of these events changes the comparison, and the shortlist should be updated to reflect the new information rather than left in the state it was in at presentation.
The update process should follow the same documentation discipline as the original shortlist. When a confirmed figure replaces an assumed figure, the score may change, and the client should be informed of the change and its effect on the ranking. When a property is withdrawn — by the landlord or by the adviser's recommendation — the reason should be documented and shared with the client.
This iterative approach treats the shortlist as a living decision document rather than a one-time deliverable. That framing reflects how transactions actually proceed: rarely in a straight line, frequently with new information that requires the original analysis to be revisited. The methodology described in this article is designed to support that revisiting process, because every score has a documented assumption behind it and every assumption can be updated when better information arrives.
The objective is to reach the moment of landlord selection with a client who has been fully informed at every stage — who knows which figures were confirmed and which were assumed, who saw the scoring update when the assumptions changed, and who made the final decision on that complete and transparent basis. That is what it means to treat off-market options fairly alongside listed buildings in a shortlist.
