33 CASTLE STREET Price Paid vs. HPI Average

The below graph shows the average terraced house price in the Boston local authority area over time, sourced from the HPI. The two 33 CASTLE STREET sales from July 2005 and September 2010 have been plotted on the graph.

For example, the July 2005 sale was for 44% above the HPI. So the extrapolation line tracks at 44% above the HPI over time, until the September 2010 sale, where it rises to 63% above the HPI. The line then continues to track at 63% above the HPI.
