Instruction likelihood is frequently misunderstood in ways that limit its usefulness. What it measures, what it does not measure, and how it should inform an agent's response are worth being precise about — because the definition determines what any classification system is actually telling the person who reads its output.
What it is not
Instruction likelihood is not a lead score. Lead scoring aggregates behavioural data about known contacts over time. It operates on accumulated history and produces a relative ranking within a pool of contacts the agency already knows. Instruction likelihood is assessed from a single interaction with an unknown contact. There is no history. The assessment comes entirely from what the seller said and what that implies about where they are in their decision.
It is also not a prediction of whether a seller will sell. Most sellers who contact an estate agency do eventually sell. The question is whether they are close to instructing an agent now.
What it actually measures
Instruction likelihood measures the probability that a seller will instruct an agent to sell their property in the near term, based on the signals present in their enquiry at the point of first contact.
Near term is relative to the seller's context. For a seller with a defined move date three months away, near term is three months. For a seller who has identified a purchase property and needs to sell to proceed, near term may be weeks. The assessment is not against an absolute calendar but against the seller's own timeline.
The signals that feed the assessment are intent, readiness, and motivation. Each contributes independently. A seller with high intent but no stated motivation and no defined timeline is assessed differently from a seller with clear motivation, a defined timeline, and evidence of decision progress, even if the surface language of both enquiries is similar.
The three states
Instruction likelihood resolves to one of three states at the point of assessment. An imminent seller is one whose signals indicate they are in active decision mode and likely to instruct within a short window. A developing seller is one whose signals indicate genuine intent but a longer or less defined timeline. A watching seller is one whose signals indicate early-stage interest with no clear instruction horizon.
These states are not fixed. A watching seller who receives a job offer in another city becomes an imminent seller. A developing seller whose target purchase falls through may retreat to watching. The assessment reflects the seller's position at the point of first contact. It does not predict how that position will change.
What can change the assessment
New information from the seller changes the assessment. A follow-up call that reveals the seller has already received three valuations and is choosing between agents this week upgrades the assessment regardless of what the initial enquiry contained. A conversation that reveals the seller is two years from retirement and was simply curious about current values adjusts the assessment downward.
The initial assessment from the enquiry is the starting point. It determines the urgency and nature of the first response. Subsequent contact refines it. The assessment at intake is not a permanent classification. It is the best available reading of a seller's position from limited information, produced at the moment it is most needed.
How it should be used
Instruction likelihood should be used to sequence and differentiate the agency's response to its inbox. Imminent sellers receive immediate, personalised attention. Developing sellers receive a substantive response with a follow-up cadence that matches their timeline. Watching sellers receive an appropriate acknowledgement and enter a longer nurture sequence.
The output is not a verdict. It is a routing decision. The agent receiving the classification uses it to calibrate their response, not to dismiss or deprioritise contacts that do not score highly. Every seller who enquires is a future instruction. The question is which ones are instructions now, and which ones need a different kind of attention in the meantime.
