48A HARMER GREEN LANE 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 48A HARMER GREEN LANE sales from April 2008 and October 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 April 2008 sale was for 81% above the HPI. So the extrapolation line tracks at 81% above the HPI over time, until the October 2018 sale, where it rises to 130% above the HPI.
