21A GUN LANE Price Paid vs. HPI Average

The below graph shows the average detached house price in the North Hertfordshire local authority area over time, sourced from the HPI. The two 21A GUN LANE sales from December 2003 and November 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 December 2003 sale was for 13% below the HPI. So the extrapolation line tracks at 13% below the HPI over time, until the November 2019 sale, where it falls to 33% below the HPI. The line then continues to track at 33% below the HPI.
