How the estimate is made

The estimate for 1a is modelled from its 64 m² EPC floor area, the absence of a recorded sale and recent sales of comparable homes in SE21 8EA. 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. No sale is recorded for 1a, which usually means it hasn't changed hands since 1995 or the sale was not for value. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.

Reading the EPC

Planning records
