20 MENDLESHAM 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 four 20 MENDLESHAM sales between January 1997 and May 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 October 2014 sale was for 13% below the HPI. So the extrapolation line tracks at 13% below the HPI over time, until the May 2018 sale, where it falls to 21% below the HPI. The line then continues to track at 21% below the HPI.
