28 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 four 28 DOL Y DDERWEN sales between April 2000 and March 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 September 2013 sale was for 10% below the HPI. So the extrapolation line tracks at 10% below the HPI over time, until the March 2021 sale, where it falls to 11% below the HPI. The line then continues to track at 11% below the HPI.

What might 28 DOL Y DDERWEN be worth now?

This is based on house price inflation of 23%, between March 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 23% inflationary increase is applied to the most recent sale price for 28 DOL Y DDERWEN of £199,500 on 16th March 2021. For the value to have increased from £199,500 to £245,376 over the four years and one month to February 2025, the following assumptions must hold true:
