55 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 55 CASTLE STREET sales from January 1998 and December 2011 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 January 1998 sale was for 2% below the HPI. So the extrapolation line tracks at 2% below the HPI over time, until the December 2011 sale, where it falls to 19% below the HPI. The line then continues to track at 19% below the HPI.

What might 55 CASTLE STREET be worth now?
