17 PLAS Y DDOL 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 17 PLAS Y DDOL sales between December 1999 and November 2018 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 2003 sale was for 41% above the HPI. So the extrapolation line tracks at 41% above the HPI over time, until the November 2018 sale, where it falls to 2% above the HPI. The line then continues to track at 2% above the HPI.

What might 17 PLAS Y DDOL be worth now?

17 PLAS Y DDOL might now be worth an estimated £280,613.

This is based on house price inflation of 38.9%, between November 2018 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 38.9% inflationary increase is applied to the most recent sale price for 17 PLAS Y DDOL of £202,000 on 28th November 2018. For the value to have increased from £202,000 to £280,613 over the seven years and nine months to February 2025, the following assumptions must hold true:

• The value of 17 PLAS Y DDOL has moved in line with the HPI for detached houses in the Carmarthenshire local authority area.
