The below graph shows the average semi-detached house price in the Monmouthshire local authority area over time, sourced from the HPI. The three 15 PRIORY CLOSE sales between March 1995 and May 2026 have been plotted on the graph.

For example, the July 2015 sale was for 13% above the HPI. So the extrapolation line tracks at 13% above the HPI over time, until the May 2026 sale, where it rises to 14% above the HPI.
