The below graph shows the average detached house price in the Welwyn Hatfield local authority area over time, sourced from the HPI. The two 47 HARMER GREEN LANE sales from June 2005 and October 2023 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 2005 sale was for 94% above the HPI. So the extrapolation line tracks at 94% above the HPI over time, until the October 2023 sale, where it rises to 302% above the HPI.
