21 HEOL TROTHY 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 21 HEOL TROTHY sales from February 2011 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 February 2011 sale was for 3% below the HPI. So the extrapolation line tracks at 3% below the HPI over time, until the December 2021 sale, where it rises to 1% below the HPI. The line then continues to track at 1% below the HPI.

What might 21 HEOL TROTHY be worth now?

21 HEOL TROTHY might now be worth an estimated £494,777.

This is based on house price inflation of 13.8%, between December 2021 and July 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 13.8% inflationary increase is applied to the most recent sale price for 21 HEOL TROTHY of £434,950 on 7th December 2021. For the value to have increased from £434,950 to £494,777 over the five years and five months to July 2026, the following assumptions must hold true:

  • The value of 21 HEOL TROTHY has moved in line with the HPI for detached houses in the Monmouthshire local authority area.
  • The December 2021 sale price of £434,950 represented a fair market value for the property.
  • The size, condition, and specification of 21 HEOL TROTHY has not materially changed since December 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.
