19 WILLIAM STREET Price Paid vs. HPI Average

The below graph shows the average detached house price in the Wiltshire local authority area over time, sourced from the HPI. The two 19 WILLIAM STREET sales from July 2005 and April 2022 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 2005 sale was for 38% below the HPI. So the extrapolation line tracks at 38% below the HPI over time, until the April 2022 sale, where it falls to 42% below the HPI. The line then continues to track at 42% below the HPI.

What might 19 WILLIAM STREET be worth now?
