Multiple signals.
One clear score.
Each of the 549,000+ London residential properties in our database is evaluated against a proprietary set of predictive signals. Each signal carries an independent weight, calibrated against historical transaction patterns. The signals are combined into a single probability score, and properties are classified as High or Medium likelihood, ranked within their London segment.
No single signal is definitive. The model looks for convergence — properties where multiple independent factors are pointing in the same direction at the same time. A property flagged on several dimensions simultaneously is a fundamentally different prospect to one with a single indicator.
We do not purchase, infer, or model private consumer data. All inputs are drawn from legitimate public record sources in accordance with UK data protection law.
Ownership tenure & equity
How long a property has been held, and the financial position that creates. Long-term owners accumulate equity and increasingly enter the life stages — retirement, downsizing, estate planning — most closely associated with a decision to sell. Properties in this category represent some of the most motivated and financially confident sellers in the market.
Property activity & improvement
Changes made to a property — physical improvements, planning activity, significant maintenance — follow a well-established pattern that precedes sale. Owners who have recently invested in preparing a property are statistically more likely to proceed to market within the following twelve months.
Ownership transitions
Changes in who holds or benefits from a property — whether through estate matters, structural change, or shifts in occupancy — create a distinct window of elevated sale probability. These transitions are identifiable in advance and represent some of the highest-confidence signals in our model.
Regulatory & financial pressure
The holding cost of residential property is rising for certain owner types. Evolving legislation, increasing compliance requirements, and shifting financial incentives are creating structured exit pressure — particularly for investment and portfolio holdings. Our model identifies where this pressure is most acute.
Market timing & price position
Where a property sits relative to its last transacted value, and how long it has been absent from the open market, tells us a great deal about owner awareness and readiness. Properties with exceptional unrealised appreciation and no recent listing history represent some of the most significant untapped opportunity in London.
What the score
means in practice
Properties are classified into two action bands. Both represent elevated probability relative to the London baseline — the distinction is one of timing and confidence, not of absolute certainty.
Act now
Multiple strong signals are present simultaneously. The combination of factors suggests a sale decision is likely within the next three months. These properties receive a personal letter and QR code for immediate portal access.
Watch closely
One or two signals are present, or signals are present but not yet at full strength. These properties are monitored monthly and will typically move to High classification within three to six months if signals develop.
