20 ILLINGWORTH Price Paid vs. HPI Average

The below graph shows the average detached house price in the Windsor and Maidenhead local authority area over time, sourced from the HPI. The three 20 ILLINGWORTH sales between February 2003 and July 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 March 2016 sale was for 10% above the HPI. So the extrapolation line tracks at 10% above the HPI over time, until the July 2021 sale, where it rises to 15% above the HPI. The line then continues to track at 15% above the HPI.

What might 20 ILLINGWORTH be worth now?
