Valuation method in detail
How the estimate is made
The estimate for Blacktown Farm is modelled from its 275 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in CF3 2UB. 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 Blacktown Farm. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
Reading the EPC
Energy Performance Certificates rate homes from A (most efficient) to G and last 10 years. The latest one for Blacktown Farm was lodged in November 2009 at band C and expired in November 2019, so a new one is needed to sell or let.

Planning records

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 2UB.
Council tax band
