21 NORTH WESTERN AVENUE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the West Northamptonshire local authority area over time, sourced from the HPI. The three 21 NORTH WESTERN AVENUE sales between July 2001 and May 2016 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 2006 sale was for 8% above the HPI. So the extrapolation line tracks at 8% above the HPI over time, until the May 2016 sale, where it rises to 16% above the HPI. The line then continues to track at 16% above the HPI.

What might 21 NORTH WESTERN AVENUE be worth now?
