The below graph shows the average terraced house price in the Carmarthenshire local authority area over time, sourced from the HPI. The seven 28 CLOS Y DERI sales between June 1997 and October 2023 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 2021 sale was for 3% above the HPI. So the extrapolation line tracks at 3% above the HPI over time, until the October 2023 sale, where it rises to 4% above the HPI. The line then continues to track at 4% above the HPI.

28 CLOS Y DERI might now be worth an estimated £155,963.
This is based on house price inflation of 5.7%, between October 2023 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 5.7% inflationary increase is applied to the most recent sale price for 28 CLOS Y DERI of £147,500 on 27th October 2023. For the value to have increased from £147,500 to £155,963 over the two years and three months to July 2025, the following assumptions must hold true:
