The below graph shows the average terraced house price in the Carmarthenshire local authority area over time, sourced from the HPI. The five 30 CLOS Y DERI sales between February 1997 and May 2019 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 2006 sale was for 7% below the HPI. So the extrapolation line tracks at 7% below the HPI over time, until the May 2019 sale, where it falls to 9% below the HPI. The line then continues to track at 9% below the HPI.

30 CLOS Y DERI might now be worth an estimated £137,127.
This is based on house price inflation of 48.2%, between May 2019 and July 2025, for terraced 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 48.2% inflationary increase is applied to the most recent sale price for 30 CLOS Y DERI of £92,500 on 24th May 2019. For the value to have increased from £92,500 to £137,127 over the five years and ten months to July 2025, the following assumptions must hold true:
