- How the estimate is made
- The estimate for 21 Janson Road is modelled from its 150 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in SO15 5FU. 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 21 Janson Road. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
- Reading the EPC

- Council tax band
- 21 Janson Road is in council tax band B. Bands are set by the Valuation Office Agency from historic values (1 April 1991 in England, 1 April 2003 in Wales), not today's price; the amount you pay depends on the council's rate for the band.
