91 MAINDIFF DRIVE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Monmouthshire local authority area over time, sourced from the HPI. The two 91 MAINDIFF DRIVE sales from August 2020 and December 2025 have been plotted on the graph. A line has been extrapolated to show what the value of the property might have been over time, following each sale, had it maintained the same margin above or below the HPI (as a percentage). For example, the August 2020 sale was for 38% below the HPI. So the extrapolation line tracks at 38% below the HPI over time, until the December 2025 sale, where it rises to 15% below the HPI. The line then continues to track at 15% below the HPI.
