20 LLYS Y DERI 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 20 LLYS Y DERI sales from October 2005 and December 2021 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 2005 sale was for 10% above the HPI. So the extrapolation line tracks at 10% above the HPI over time, until the December 2021 sale, where it rises to 18% above the HPI. The line then continues to track at 18% above the HPI.

What might 20 LLYS Y DERI be worth now?

20 LLYS Y DERI might now be worth an estimated £326,610.

This is based on house price inflation of 10.7%, between December 2021 and February 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 10.7% inflationary increase is applied to the most recent sale price for 20 LLYS Y DERI of £295,000 on 3rd December 2021. For the value to have increased from £295,000 to £326,610 over the four years and ten months to February 2025, the following assumptions must hold true:

• The value of 20 LLYS Y DERI has moved in line with the HPI for detached houses in the Carmarthenshire local authority area.
• The December 2021 sale price of £295,000 represented a fair market value for the property.
