21 KILMISTON AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Spelthorne local authority area over time, sourced from the HPI. The two 21 KILMISTON AVENUE sales from August 2003 and June 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 August 2003 sale was for 16% below the HPI. So the extrapolation line tracks at 16% below the HPI over time, until the June 2021 sale, where it rises to 11% below the HPI. The line then continues to track at 11% below the HPI.

What might 21 KILMISTON AVENUE be worth now?
