18 FIRS AVENUE Price Paid vs. HPI Average

The below graph shows the average terraced house price in the Windsor and Maidenhead local authority area over time, sourced from the HPI. The three 18 FIRS AVENUE sales between November 1997 and October 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 September 2002 sale was for 1% above the HPI. So the extrapolation line tracks at 1% above the HPI over time, until the October 2004 sale, where it rises to 3% above the HPI. The line then continues to track at 3% above the HPI.
