1 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 1 MARDLEY HEIGHTS sales from June 2008 and May 2021 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 June 2008 sale was for 13% above the HPI. So the extrapolation line tracks at 13% above the HPI over time, until the May 2021 sale, where it falls to 4% below the HPI. The line then continues to track at 4% below the HPI.
