26 BASILDENE CLOSE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Monmouthshire local authority area over time, sourced from the HPI. The two 26 BASILDENE CLOSE sales from June 2010 and May 2022 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 June 2010 sale was for 12% above the HPI. So the extrapolation line tracks at 12% above the HPI over time, until the May 2022 sale, where it rises to 14% above the HPI. The line then continues to track at 14% above the HPI.

What might 26 BASILDENE CLOSE be worth now?

26 BASILDENE CLOSE might now be worth an estimated £337,356.

This is based on house price inflation of 7.1%, between May 2022 and February 2025, for semi-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 7.1% inflationary increase is applied to the most recent sale price for 26 BASILDENE CLOSE of £315,000 on 5th May 2022. For the value to have increased from £315,000 to £337,356 over the three years and three months to February 2025, the following assumptions must hold true:

  • The value of 26 BASILDENE CLOSE has moved in line with the HPI for semi-detached houses in the Monmouthshire local authority area.
  • The May 2022 sale price of £315,000 represented a fair market value for the property.
  • The size, condition, and specification of 26 BASILDENE CLOSE has not materially changed since May 2022.
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.
