I know about Zoopla, where you can look up an address and see price history.
But is there anywhere that provides a view of prices by date and area, i.e. you could search and it would show what had been sold at what prices in an area in a given year? You could see what a certain amount would have bought in a location at the time, like a historical Rightmove search. (Since whenever it was these records started being public the way they are in Zoopla)
