8 FIRS AVENUE 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 8 FIRS AVENUE sales between April 1995 and January 2013 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 October 1996 sale was for 54% below the HPI. So the extrapolation line tracks at 54% below the HPI over time, until the January 2013 sale, where it rises to 49% below the HPI. The line then continues to track at 49% below the HPI.
