9 MARDLEY HEIGHTS 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 two 9 MARDLEY HEIGHTS sales from December 1997 and November 2005 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 December 1997 sale was for 41% above the HPI. So the extrapolation line tracks at 41% above the HPI over time, until the November 2005 sale, where it falls to 55% below the HPI.
