20 ASH GROVE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Dacorum local authority area over time, sourced from the HPI. The three 20 ASH GROVE sales between October 1996 and August 2012 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 February 2008 sale was for 53% below the HPI. So the extrapolation line tracks at 53% below the HPI over time, until the August 2012 sale, where it rises to 35% below the HPI. The line then continues to track at 35% below the HPI.
