The below graph shows the average detached house price in the West Northamptonshire local authority area over time, sourced from the HPI. The two 9 ROUNDING STREET sales from September 2016 and October 2025 have been plotted on the graph.

For example, the September 2016 sale was for 44% below the HPI. So the extrapolation line tracks at 44% below the HPI over time, until the October 2025 sale, where it rises to 31% below the HPI.
