10 UPPER COSMESTON FARM 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 three 10 UPPER COSMESTON FARM sales between June 1995 and October 2012 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 December 2005 sale was for 20% above the HPI. So the extrapolation line tracks at 20% above the HPI over time, until the October 2012 sale, where it falls to 3% above the HPI. The line then continues to track at 3% above the HPI.
