The below graph shows the average detached house price in the Swansea local authority area over time, sourced from the HPI. The three 4 DEVON PLACE sales between February 2004 and October 2011 have been plotted on the graph.

For example, the January 2006 sale was for 39% above the HPI. So the extrapolation line tracks at 39% above the HPI over time, until the October 2011 sale, where it rises to 52% above the HPI.
