8 CLOS TREVENTY Price Paid vs. HPI Average

The below graph shows the average detached house price in the Carmarthenshire local authority area over time, sourced from the HPI. The two 8 CLOS TREVENTY sales from July 2006 and February 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 July 2006 sale was for 42% above the HPI. So the extrapolation line tracks at 42% above the HPI over time, until the February 2025 sale, where it rises to 57% above the HPI. The line then continues to track at 57% above the HPI.

What might 8 CLOS TREVENTY be worth now?

8 CLOS TREVENTY might now be worth an estimated £440,256.

This is based on house price inflation of 2.9%, between February 2025 and June 2025, for detached houses, in the Carmarthenshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 2.9% inflationary increase is applied to the most recent sale price for 8 CLOS TREVENTY of £428,000 on 28th February 2025. For the value to have increased from £428,000 to £440,256 over the eight months to June 2025, the following assumptions must hold true:

• The value of 8 CLOS TREVENTY has moved in line with the HPI for detached houses in the Carmarthenshire local authority area.
• The February 2025 sale price of £428,000 represented a fair market value for the property.
• The size, condition, and specification of 8 CLOS TREVENTY has not materially changed since February 2025.
