This estimate starts from the price paid for this home in September 2018 and moves it in line with the UK House Price Index for England. It then allows for how long ago that sale was.
It is a market estimate — not a RICS survey or a mortgage valuation. The range is wider the longer ago the sale was. It is set from how far estimates like this have been from later sale prices; a sale can still fall outside it.
This is an estimate from one past sale and a national index. It does not know this home’s condition, any work done since, or how prices have moved in this area.
