TY 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 three TY DDERWEN sales between July 1997 and March 2026 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 September 2019 sale was for 19% below the HPI. So the extrapolation line tracks at 19% below the HPI over time, until the March 2026 sale, where it rises to 8% above the HPI. The line then continues to track at 8% above the HPI.

What might TY DDERWEN be worth now?

TY DDERWEN might now be worth an estimated £302,213.

This is based on house price deflation of 0.9%, between March 2026 and May 2026, 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 0.9% deflationary decrease is applied to the most recent sale price for TY DDERWEN of £305,000 on 10th March 2026. For the value to have decreased from £305,000 to £302,213 over the ten months to May 2026, the following assumptions must hold true:

• The value of TY DDERWEN has moved in line with the HPI for detached houses in the Carmarthenshire local authority area.
• The March 2026 sale price of £305,000 represented a fair market value for the property.
• The size, condition, and specification of TY DDERWEN has not materially changed since March 2026.
