18 BLAEN NANT Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Carmarthenshire local authority area over time, sourced from the HPI. The three 18 BLAEN NANT sales between August 1995 and January 2004 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 August 1996 sale was for 1% above the HPI. So the extrapolation line tracks at 1% above the HPI over time, until the January 2004 sale, where it rises to 2% above the HPI. The line then continues to track at 2% above the HPI.

What might 18 BLAEN NANT be worth now?

18 BLAEN NANT might now be worth an estimated £184,642.

This is based on house price inflation of 133.7%, between January 2004 and June 2025, for semi-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 133.7% inflationary increase is applied to the most recent sale price for 18 BLAEN NANT of £79,000 on 29th January 2004. For the value to have increased from £79,000 to £184,642 over the twenty years and seven months to June 2025, the following assumptions must hold true:

• The value of 18 BLAEN NANT has moved in line with the HPI for semi-detached houses in the Carmarthenshire local authority area.
• The January 2004 sale price of £79,000 represented a fair market value for the property.
