The below graph shows the average terraced house price in the Buckinghamshire local authority area over time, sourced from the HPI. The three 21 WINDMILL CLOSE sales between June 1995 and December 2025 have been plotted on the graph. A line has been extrapolated to show what the value of the property might have been over time, following each sale, had it maintained the same margin above or below the HPI (as a percentage). For example, the July 2007 sale was for 8% below the HPI. So the extrapolation line tracks at 8% below the HPI over time, until the December 2025 sale, where it falls to 18% below the HPI. The line then continues to track at 18% below the HPI.

21 WINDMILL CLOSE might now be worth an estimated £308,971.
