How the estimate is made
The estimate for 4 Canopus Close is modelled from its 68 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in CF3 1NR. 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. 2 sales are recorded for 4 Canopus Close. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.

Area figures
Crime is police-recorded street-level data over the last 18 months, which places each incident at an approximate point. Schools and stops are measured in a straight line from CF3 1NR.
Council tax band
4 Canopus Close is in council tax band D. 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.
