The below graph shows the average detached house price in the Swindon local authority area over time, sourced from the HPI. The three 17 ROUNDWAY DOWN sales between March 1996 and June 2023 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 January 2017 sale was for 28% below the HPI. So the extrapolation line tracks at 28% below the HPI over time, until the June 2023 sale, where it rises to 26% below the HPI. The line then continues to track at 26% below the HPI.

17 ROUNDWAY DOWN might now be worth an estimated £343,958.
This is based on house price inflation of 1.2%, between June 2023 and April 2026, for detached houses, in the Swindon local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
