4 DATCHWORTH GREEN Price Paid vs. HPI Average

The below graph shows the average detached house price in the East Hertfordshire local authority area over time, sourced from the HPI. The three 4 DATCHWORTH GREEN sales between May 2004 and August 2014 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 2006 sale was for 40% above the HPI. So the extrapolation line tracks at 40% above the HPI over time, until the August 2014 sale, where it rises to 64% above the HPI. The line then continues to track at 64% above the HPI.
