21 CLOS Y DDERWEN 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 21 CLOS Y DDERWEN sales from October 1996 and June 1998 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 October 1996 sale was for 69% below the HPI. So the extrapolation line tracks at 69% below the HPI over time, until the June 1998 sale, where it rises to 105% above the HPI. The line then continues to track at 105% above the HPI.

What might 21 CLOS Y DDERWEN be worth now?

21 CLOS Y DDERWEN might now be worth an estimated £574,373.

This is based on house price inflation of 343.5%, between June 1998 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 343.5% inflationary increase is applied to the most recent sale price for 21 CLOS Y DDERWEN of £129,500 on 9th June 1998. For the value to have increased from £129,500 to £574,373 over the 27 years to June 2025, the following assumptions must hold true:

• The value of 21 CLOS Y DDERWEN has moved in line with the HPI for detached houses in the Carmarthenshire local authority area.
• The June 1998 sale price of £129,500 represented a fair market value for the property.
