EEL MARSH HOUSE 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 EEL MARSH HOUSE sales from October 2004 and April 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 October 2004 sale was for 38% above the HPI. So the extrapolation line tracks at 38% above the HPI over time, until the April 2008 sale, where it rises to 152% above the HPI. The line then continues to track at 152% above the HPI.
