- How the estimate is made
- The estimate for 21 Berkeley Close is modelled from its 103 m² EPC floor area, its 3 recorded sales and recent sales of comparable homes in NN1 5BJ. 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 Berkeley Close. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.

- Energy Performance Certificates rate homes from A (most efficient) to G and last 10 years. The latest one for 21 Berkeley Close was lodged in October 2020 at band C and is valid until October 2030. Floor area, heating and insulation details on this page come from it.

- Area figures
- Crime is police-recorded street-level data over the last 16 months, which places each incident at an approximate point. The 26 schools and 30 stops listed are measured in a straight line from NN1 5BJ, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
- Council tax band
- 21 Berkeley Close is in council tax band D. 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.
