DERWYDD 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 DERWYDD sales from January 2017 and December 2022 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 January 2017 sale was for 119% above the HPI. So the extrapolation line tracks at 119% above the HPI over time, until the December 2022 sale, where it rises to 141% above the HPI. The line then continues to track at 141% above the HPI.

What might DERWYDD be worth now?

DERWYDD might now be worth an estimated £673,522.

This is based on house price deflation of 1.7%, between December 2022 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 1.7% deflationary decrease is applied to the most recent sale price for DERWYDD of £685,000 on 1st December 2022. For the value to have decreased from £685,000 to £673,522 over the three years and six months to June 2025, the following assumptions must hold true:

• The value of DERWYDD has moved in line with the HPI for detached houses in the Carmarthenshire local authority area.
• The December 2022 sale price of £685,000 represented a fair market value for the property.
• The size, condition, and specification of DERWYDD has not materially changed since December 2022.
