How the estimate is made

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 every figure above comes from, how current it is and what it can't tell you.
- How the estimate is made
- The estimate for 9 Clos Cas Bach is modelled from its 94 m² EPC floor area, the absence of a recorded sale and recent sales of comparable homes in CF3 0AU. 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 9 Clos Cas Bach, 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.
