THORNBURY Price Paid vs. HPI Average

The below graph shows the average detached house price in the Sevenoaks local authority area over time, sourced from the HPI. The four THORNBURY sales between October 2002 and November 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 July 2006 sale was for 14% below the HPI. So the extrapolation line tracks at 14% below the HPI over time, until the November 2009 sale, where it falls to 18% below the HPI. The line then continues to track at 18% below the HPI.
