The below graph shows the average detached house price in the Monmouthshire local authority area over time, sourced from the HPI. The two 15 CORNFORD CLOSE sales from November 2018 and October 2025 have been plotted on the graph.

For example, the November 2018 sale was for 54% above the HPI. So the extrapolation line tracks at 54% above the HPI over time, until the October 2025 sale, where it falls to 38% above the HPI.
