21 WEST STREET Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the North Northamptonshire local authority area over time, sourced from the HPI. The five 21 WEST STREET sales between July 1996 and October 2015 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 June 2004 sale was for 238% above the HPI. So the extrapolation line tracks at 238% above the HPI over time, until the October 2015 sale, where it falls to 207% above the HPI. The line then continues to track at 207% above the HPI.

What might 21 WEST STREET be worth now?
