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 11 UPPER COSMESTON FARM sales between July 1995 and February 2024 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 2014 sale was for 15% above the HPI. So the extrapolation line tracks at 15% above the HPI over time, until the February 2024 sale, where it falls to 6% above the HPI. The line then continues to track at 6% above the HPI.
11 UPPER COSMESTON FARM might now be worth an estimated £541,937.
