6 DUNSTER DRIVE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Vale of Glamorgan local authority area over time, sourced from the HPI. The four 6 DUNSTER DRIVE sales between June 1998 and July 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 June 2011 sale was for 4% below the HPI. So the extrapolation line tracks at 4% below the HPI over time, until the July 2025 sale, where it falls to 12% below the HPI. The line then continues to track at 12% below the HPI.

What might 6 DUNSTER DRIVE be worth now?
