39 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 three 39 MARDLEY HILL sales between August 2006 and November 2022 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 October 2012 sale was for 49% above the HPI. So the extrapolation line tracks at 49% above the HPI over time, until the November 2022 sale, where it falls to 45% above the HPI. The line then continues to track at 45% above the HPI.
