10 CLOS ALWEN 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 10 CLOS ALWEN sales from March 1999 and February 2021 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 March 1999 sale was for 8% below the HPI. So the extrapolation line tracks at 8% below the HPI over time, until the February 2021 sale, where it falls to 16% below the HPI. The line then continues to track at 16% below the HPI.

What might 10 CLOS ALWEN be worth now?

10 CLOS ALWEN might now be worth an estimated £400,190.

This is based on house price inflation of 14.3%, between February 2021 and July 2025, 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 14.3% inflationary increase is applied to the most recent sale price for 10 CLOS ALWEN of £350,000 on 12th February 2021. For the value to have increased from £350,000 to £400,190 over the three years and seven months to July 2025, the following assumptions must hold true:

  • The value of 10 CLOS ALWEN has moved in line with the HPI for detached houses in the Monmouthshire local authority area.
  • The February 2021 sale price of £350,000 represented a fair market value for the property.
  • The size, condition, and specification of 10 CLOS ALWEN has not materially changed since February 2021.
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.
