The below graph shows the average terraced house price in the Carmarthenshire local authority area over time, sourced from the HPI. The two 16 DOL Y DDERWEN sales from February 2009 and April 2014 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 February 2009 sale was for 2% above the HPI. So the extrapolation line tracks at 2% above the HPI over time, until the April 2014 sale, where it rises to 3% above the HPI. The line then continues to track at 3% above the HPI.

16 DOL Y DDERWEN might now be worth an estimated £155,059.
This is based on house price inflation of 76.2%, between April 2014 and July 2025, for terraced 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 76.2% inflationary increase is applied to the most recent sale price for 16 DOL Y DDERWEN of £88,000 on 4th April 2014. For the value to have increased from £88,000 to £155,059 over the ten years and nine months to July 2025, the following assumptions must hold true:
