Valuation method in detail
How the estimate is made
The estimate for 12 John Alder Close is modelled from its 144 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in SN4 0JL. 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 12 John Alder Close. 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.
