Valuation method in detail

How the estimate is made: The estimate for Castle Buildings is modelled from its 42 m² EPC floor area, the absence of a recorded sale and recent sales of comparable homes in SA1 1JG.

Where sold prices come from: Sold prices are HM Land Registry Price Paid Data, which covers residential sales in England and Wales since 1995. No sale is recorded for Castle Buildings, which usually means it hasn't changed hands since 1995 or the sale was not for value. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.

Planning records: Planning applications are collected from local authority registers through PlanIt. None is matched to Castle Buildings. Councils sometimes file applications under a different address format, and applications on neighbouring land aren't listed here; the report covers both.
Area figures: Crime is police-recorded street-level data over the last 16 months, which places each incident at an approximate point. Schools and stops are measured in a straight line from SA1 1JG.
Council tax band: Castle Buildings is in council tax band C. Bands are set by the Valuation Office Agency from historic values (1 April 1991 in England, 1 April 2003 in Wales), not today's price; the amount you pay depends on the council's rate for the band.
