4 HARMER DELL 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 4 HARMER DELL sales from September 1996 and October 2019 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 September 1996 sale was for 98% above the HPI. So the extrapolation line tracks at 98% above the HPI over time, until the October 2019 sale, where it falls to 39% above the HPI.
