21 LONGDEAN PARK 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 21 LONGDEAN PARK sales between December 1997 and June 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 May 2003 sale was for 55% above the HPI. So the extrapolation line tracks at 55% above the HPI over time, until the June 2013 sale, where it rises to 63% above the HPI. The line then continues to track at 63% above the HPI.
