- How the estimate is made
- The estimate for 21 Caistor Close is modelled from its 102 m² EPC floor area, its 3 recorded sales and recent sales of comparable homes in SO16 8GX. 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. 3 sales are recorded for 21 Caistor Close. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
- Reading the EPC
