The below graph shows the average terraced house price in the North Northamptonshire local authority area over time, sourced from the HPI. The two 73 UNION STREET sales from March 2006 and January 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 March 2006 sale was for 44% above the HPI. So the extrapolation line tracks at 44% above the HPI over time, until the January 2010 sale, where it falls to 36% below the HPI. The line then continues to track at 36% below the HPI.
73 UNION STREET might now be worth an estimated £128,234.
