The below graph shows the average detached house price in the West Northamptonshire local authority area over time, sourced from the HPI. The six 9 NORTH WESTERN AVENUE sales between May 1996 and April 2013 have been plotted on the graph.

For example, the May 2009 sale was for 19% above the HPI. So the extrapolation line tracks at 19% above the HPI over time, until the April 2013 sale, where it falls to 14% above the HPI. The line then continues to track at 14% above the HPI.
