Valuation method in detail

How the estimate is made: The estimate for 3 Castle Mews is modelled from its 45 m² EPC floor area, its 4 recorded sales and recent sales of comparable homes in OX1 1JR. 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. 4 sales are recorded for 3 Castle Mews. 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 3 Castle Mews was lodged in September 2021 at band C and is valid until September 2031. 3 certificates are on record, which shows how the home has changed.
Planning records: Planning applications are collected from local authority registers through PlanIt. None is matched to 3 Castle Mews. 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 17 months, which places each incident at an approximate point. The 17 schools and 30 stops listed are measured in a straight line from OX1 1JR, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
