15 WILLIAMS WAY Price Paid vs. HPI Average

The below graph shows the average detached house price in the Buckinghamshire local authority area over time, sourced from the HPI. The three 15 WILLIAMS WAY sales between April 2012 and July 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 December 2019 sale was for 29% below the HPI. So the extrapolation line tracks at 29% below the HPI over time, until the July 2020 sale, where it falls to 33% below the HPI. The line then continues to track at 33% below the HPI.

What might 15 WILLIAMS WAY be worth now?
