Valuation method in detail

How the estimate is made: The estimate for Flat 1 is modelled from its 88 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in NN1 1JT. 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 Flat 1. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.

Planning records: Planning applications are collected from local authority registers through PlanIt. None is matched to Flat 1. 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 32 schools and 30 stops listed are measured in a straight line from NN1 1JT, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
