The below graph shows the average detached house price in the West Northamptonshire local authority area over time, sourced from the HPI. The two 5 PORTWAY GARDENS sales from October 1997 and November 2019 have been plotted on the graph.

For example, the October 1997 sale was for 40% above the HPI. So the extrapolation line tracks at 40% above the HPI over time, until the November 2019 sale, where it rises to 49% above the HPI.
