18 GAINEY GARDENS Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Wiltshire local authority area over time, sourced from the HPI. The two 18 GAINEY GARDENS sales from March 2020 and January 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 March 2020 sale was for 16% below the HPI. So the extrapolation line tracks at 16% below the HPI over time, until the January 2025 sale, which was also at 16% below the HPI.

What might 18 GAINEY GARDENS be worth now?
