The two 43B CASSIOBURY PARK AVENUE sales from July 1996 and April 2003 have been plotted on the graph.

For example, the July 1996 sale was for 2% above the HPI. So the extrapolation line tracks at 2% above the HPI over time, until the April 2003 sale, where it falls to 1% above the HPI. The line then continues to track at 1% above the HPI.
