11 BOSTOCK AVENUE Price Paid vs. HPI Average

The below graph shows the average terraced house price in the West Northamptonshire local authority area over time, sourced from the HPI. The four 11 BOSTOCK AVENUE sales between December 2001 and September 2014 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 November 2005 sale was for 37% above the HPI. So the extrapolation line tracks at 37% above the HPI over time, until the September 2014 sale, where it rises to 49% above the HPI. The line then continues to track at 49% above the HPI.
