9 MARDLEY HILL 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 HILL sales from January 1997 and May 2011 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 1997 sale was for 26% below the HPI. So the extrapolation line tracks at 26% below the HPI over time, until the May 2011 sale, where it rises to 21% below the HPI. The line then continues to track at 21% below the HPI.
