How the estimate is made
The estimate for 31 Colchester Avenue is modelled from its 154 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in CF23 9BN. 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 31 Colchester Avenue. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
