21 ADELAIDE SQUARE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Windsor and Maidenhead local authority area over time, sourced from the HPI. The three 21 ADELAIDE SQUARE sales between June 1997 and July 2004 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 December 1998 sale was for 6% below the HPI. So the extrapolation line tracks at 6% below the HPI over time, until the July 2004 sale, where it falls to 12% below the HPI. The line then continues to track at 12% below the HPI.
