25 FAIRFIELD 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 25 FAIRFIELD sales from March 2016 and June 2025 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 2016 sale was for 38% below the HPI. So the extrapolation line tracks at 38% below the HPI over time, until the June 2025 sale, where it rises to 16% below the HPI. The line then continues to track at 16% below the HPI.

What might 25 FAIRFIELD be worth now?

This is based on house price deflation of 3.3%, between June 2025 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 3.3% deflationary decrease is applied to the most recent sale price for 25 FAIRFIELD of £420,000 on 25th June 2025. For the value to have decreased from £420,000 to £405,997 over the one year and one month to May 2026, the following assumptions must hold true:
