Valuation method in detail
How the estimate is made
The estimate for 15 Longman House is modelled from its 60 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in HP3 9GH. 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 15 Longman House. 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 15 Longman House was lodged in November 2016 at band B and is valid until November 2026. Floor area, heating and insulation details on this page come from it.
Planning records

Area figures
Crime is police-recorded street-level data over the last 13 months, which places each incident at an approximate point. The 17 schools and 30 stops listed are measured in a straight line from HP3 9GH, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
