11 WALLIS CLOSE 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 11 WALLIS CLOSE sales from September 2002 and October 2018 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 September 2002 sale was for 34% above the HPI. So the extrapolation line tracks at 34% above the HPI over time, until the October 2018 sale, where it falls to 7% above the HPI. The line then continues to track at 7% above the HPI.

What might 11 WALLIS CLOSE be worth now?

11 WALLIS CLOSE might now be worth an estimated £525,164.

This is based on house price inflation of 29.7%, between October 2018 and February 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 29.7% inflationary increase is applied to the most recent sale price for 11 WALLIS CLOSE of £405,000 on 1st October 2018. For the value to have increased from £405,000 to £525,164 over the seven years and eight months to February 2025, the following assumptions must hold true:

  • The value of 11 WALLIS CLOSE has moved in line with the HPI for detached houses in the Monmouthshire local authority area.
  • The October 2018 sale price of £405,000 represented a fair market value for the property.
  • The size, condition, and specification of 11 WALLIS CLOSE has not materially changed since October 2018.
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.
