15 BARNES WALLIS CLOSE 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 four 15 BARNES WALLIS CLOSE sales between August 1996 and October 2025 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 2015 sale was for 37% below the HPI. So the extrapolation line tracks at 37% below the HPI over time, until the October 2025 sale, where it rises to 33% below the HPI. The line then continues to track at 33% below the HPI.
