9 LON GWESYN Price Paid vs. HPI Average

The below graph shows the average detached house price in the Swansea local authority area over time, sourced from the HPI. The two 9 LON GWESYN sales from May 2002 and May 2008 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 May 2002 sale was for 51% below the HPI. So the extrapolation line tracks at 51% below the HPI over time, until the May 2008 sale, where it falls to 60% below the HPI. The line then continues to track at 60% below the HPI.
