17 RADYR AVENUE 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 17 RADYR AVENUE sales from July 2009 and September 2010 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 July 2009 sale was for 9% below the HPI. So the extrapolation line tracks at 9% below the HPI over time, until the September 2010 sale, where it rises to 16% above the HPI. The line then continues to track at 16% above the HPI.
