15 DOL Y 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 15 DOL Y DDERWEN sales between August 1997 and January 2016 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 April 2000 sale was for 28% above the HPI. So the extrapolation line tracks at 28% above the HPI over time, until the January 2016 sale, where it falls to 7% above the HPI. The line then continues to track at 7% above the HPI.

What might 15 DOL Y DDERWEN be worth now?

This is based on house price inflation of 60.4%, between January 2016 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 60.4% inflationary increase is applied to the most recent sale price for 15 DOL Y DDERWEN of £185,000 on 20th January 2016. For the value to have increased from £185,000 to £296,721 over the eight years and eleven months to February 2025, the following assumptions must hold true:
