22 CALTON AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the East Hertfordshire local authority area over time, sourced from the HPI. The three 22 CALTON AVENUE sales between March 1999 and September 2021 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 2005 sale was for 35% above the HPI. So the extrapolation line tracks at 35% above the HPI over time, until the September 2021 sale, where it falls to 5% below the HPI. The line then continues to track at 5% below the HPI.

What might 22 CALTON AVENUE be worth now?
