The below graph shows the average detached house price in the Swansea local authority area over time, sourced from the HPI. The two 1 WILLIAM GAMMON DRIVE sales from December 2005 and March 2018 have been plotted on the graph.

For example, the December 2005 sale was for 28% above the HPI. So the extrapolation line tracks at 28% above the HPI over time, until the March 2018 sale, where it falls to 19% above the HPI.
