Valuation method in detail

How the estimate is made: The estimate for 17a is modelled from its 76 m² EPC floor area, its 5 recorded sales and recent sales of comparable homes in BN11 3NR. 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. 5 sales are recorded for 17a. 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 17a was lodged in May 2022 at band C and is valid until May 2032. Floor area, heating and insulation details on this page come from it.
Planning records: Planning applications are collected from local authority registers through PlanIt. 1 application is matched to 17a. Councils sometimes file applications under a different address format, and applications on neighbouring land aren't listed here; the report covers both.
Area figures: Crime is police-recorded street-level data over the last 16 months, which places each incident at an approximate point. The 20 schools and 30 stops listed are measured in a straight line from BN11 3NR, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
