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 21 Castle Mews is modelled from its 36 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in NN8 1NX. 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. 2 sales are recorded for 21 Castle Mews. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.

- Area figures
- Crime is police-recorded street-level data over the last 15 months, which places each incident at an approximate point.

- Council tax band
- 21 Castle Mews is in council tax band A. 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.
