Valuation method in detail
How the estimate is made
The estimate for 45 Blackwell Drive is modelled from its 107 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in WD19 4HP. It is an automated estimate, not a survey or mortgage valuation: condition, layout and improvements that aren't on record can move the real figure either way.
Where sold prices come from
Sold prices are HM Land Registry Price Paid Data, which covers residential sales in England and Wales since 1995. 1 sale is recorded for 45 Blackwell Drive. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.

Planning records

Area figures
Crime is police-recorded street-level data over the last 13 months, which places each incident at an approximate point.

Council tax band
45 Blackwell Drive is in council tax band E. 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.
