The below graph shows the average semi-detached house price in the Swansea local authority area over time, sourced from the HPI. The two 10 WILLIAM GAMMON DRIVE sales from August 2006 and December 2015 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 August 2006 sale was for 64% above the HPI. So the extrapolation line tracks at 64% above the HPI over time, until the December 2015 sale, where it falls to 47% above the HPI. The line then continues to track at 47% above the HPI.
