6 SWANGLEYS 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 6 SWANGLEYS LANE sales from November 2004 and April 2022 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 November 2004 sale was for 36% above the HPI. So the extrapolation line tracks at 36% above the HPI over time, until the April 2022 sale, where it rises to 55% above the HPI. The line then continues to track at 55% above the HPI.
