47 THUNDERSLEY GROVE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Castle Point local authority area over time, sourced from the HPI. The two 47 THUNDERSLEY GROVE sales from January 2002 and June 2009 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 January 2002 sale was for 9% below the HPI. So the extrapolation line tracks at 9% below the HPI over time, until the June 2009 sale, where it rises to 55% above the HPI. The line then continues to track at 55% above the HPI.
