11 MILL COMMON 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 four 11 MILL COMMON sales between June 2002 and October 2023 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 April 2017 sale was for 21% below the HPI. So the extrapolation line tracks at 21% below the HPI over time, until the October 2023 sale, where it falls to 27% below the HPI. The line then continues to track at 27% below the HPI.

What might 11 MILL COMMON be worth now?

11 MILL COMMON might now be worth an estimated £350,339.

This is based on house price deflation of 2.1%, between October 2023 and April 2026, for detached houses, in the Monmouthshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 2.1% deflationary decrease is applied to the most recent sale price for 11 MILL COMMON of £358,000 on 12th October 2023. For the value to have decreased from £358,000 to £350,339 over the three years and six months to April 2026, the following assumptions must hold true:

  • The value of 11 MILL COMMON has moved in line with the HPI for detached houses in the Monmouthshire local authority area.
  • The October 2023 sale price of £358,000 represented a fair market value for the property.
  • The size, condition, and specification of 11 MILL COMMON has not materially changed since October 2023.
Disclaimer: Please note that this is a theoretical estimate based on assumptions which may or may not be correct. It should not be relied on for any purpose.
