31 DOCK STREET Price Paid vs. HPI Average

The below graph shows the average terraced house price in the Vale of Glamorgan local authority area over time, sourced from the HPI. The six 31 DOCK STREET sales between January 2001 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 April 2025 sale was for 7% below the HPI. So the extrapolation line tracks at 7% below the HPI over time, until the November 2025 sale, where it rises to 3% below the HPI. The line then continues to track at 3% below the HPI.
