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 121 High Street is modelled from its 58 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in PO1 2HW.

- 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 121 High Street. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
