71 COG ROAD 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 two 71 COG ROAD sales from January 1998 and November 2005 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 1998 sale was for 94% above the HPI. So the extrapolation line tracks at 94% above the HPI over time, until the November 2005 sale, where it falls to 88% above the HPI. The line then continues to track at 88% above the HPI.
