29 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 seven 29 MARDLEY HILL sales between March 1998 and February 2018 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 November 2013 sale was for 24% above the HPI. So the extrapolation line tracks at 24% above the HPI over time, until the February 2018 sale, where it falls to 5% above the HPI. The line then continues to track at 5% above the HPI.
