The below graph shows the average detached house price in the Vale of Glamorgan local authority area over time, sourced from the HPI. The two 17 UPPER COSMESTON FARM sales from February 2007 and May 2014 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 February 2007 sale was for 17% above the HPI. So the extrapolation line tracks at 17% above the HPI over time, until the May 2014 sale, where it falls to 11% above the HPI. The line then continues to track at 11% above the HPI.
17 UPPER COSMESTON FARM might now be worth an estimated £565,951.
