24 MARTLESHAM Price Paid vs. HPI Average

The below graph shows the average detached house price in the Welwyn Hatfield local authority area over time, sourced from the HPI. The three 24 MARTLESHAM sales between November 2001 and July 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 August 2008 sale was for 37% below the HPI. So the extrapolation line tracks at 37% below the HPI over time, until the July 2014 sale, where it falls to 39% below the HPI. The line then continues to track at 39% below the HPI.
