CASTLE GROUNDS HOUSE 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 three CASTLE GROUNDS HOUSE sales between January 2007 and November 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 94% above the HPI. So the extrapolation line tracks at 94% above the HPI over time, until the November 2025 sale, where it falls to 72% above the HPI. The line then continues to track at 72% above the HPI.

What might CASTLE GROUNDS HOUSE be worth now?
