The below graph shows the average detached house price in the Northumberland local authority area over time, sourced from the HPI. The two 9 SIMONSIDE sales from June 1996 and July 2026 have been plotted on the graph.

For example, the June 1996 sale was for 1% above the HPI. So the extrapolation line tracks at 1% above the HPI over time, until the July 2026 sale, where it rises to 42% above the HPI. The line then continues to track at 42% above the HPI.
