Per listing we take the most recent scored snapshot in the window and compute the asking-vs-estimate premium (asking minus the free HM Land Registry sold-price estimate, as a percentage of the estimate); per outcode and nationally we publish the MEDIAN premium, the share of tracked listings with at least one observed price reduction, and the median reduction size. Medians over observed rows only — no extrapolation, no LLM in the numbers path. Aggregates backed by fewer than 30 listings are not published.","method_version":"1","computed_at":null,"window_days":90,"min_n":30,"licence":"Open Government Licence v3.0 (underlying estimate data)","attribution":["Contains HM Land Registry data © Crown copyright and database right.
