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 12 Clos Llewellyn is modelled from its 92 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in CF15 7AT. 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 12 Clos Llewellyn. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
- Reading the EPC
