Citywide sales totals can provide context, but a property operates within a particular building and catchment. Local evidence is needed to connect the two.
Separate the levels
Identify what the aggregate figure measures. Then investigate appropriate nearby comparisons, access, specification and competing supply. Do not infer a unit's value from a different segment's activity.
Record the uncertainty
Mark which observations are current and which are forecasts. Obtain the actual property's costs and terms. A useful analysis explains where broader data helps and where it stops answering the buyer's question.
