17 STOCKENS GREEN 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 three 17 STOCKENS GREEN sales between May 1998 and November 2020 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 July 2008 sale was for 11% below the HPI. So the extrapolation line tracks at 11% below the HPI over time, until the November 2020 sale, where it rises to 9% above the HPI. The line then continues to track at 9% above the HPI.

What might 17 STOCKENS GREEN be worth now?
