The below graph shows the average detached house price in the Monmouthshire local authority area over time, sourced from the HPI. The five 8 BASILDENE CLOSE sales between March 1998 and December 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 December 2013 sale was for 35% below the HPI. So the extrapolation line tracks at 35% below the HPI over time, until the December 2021 sale, where it rises to 14% below the HPI. The line then continues to track at 14% below the HPI.

8 BASILDENE CLOSE might now be worth an estimated £414,500.
This is based on house price inflation of 10.5%, between December 2021 and May 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 10.5% inflationary increase is applied to the most recent sale price for 8 BASILDENE CLOSE of £375,000 on 10th December 2021. For the value to have increased from £375,000 to £414,500 over the five years and seven months to May 2026, the following assumptions must hold true:
