Valuation method in detail
How the estimate is made
The estimate for 13 Gainsborough Avenue is modelled from its 180 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in AL1 4NJ. 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 13 Gainsborough Avenue. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.

Planning records

Area figures

Council tax band
13 Gainsborough Avenue is in council tax band G. 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.
