The below graph shows the average terraced house price in the Carmarthenshire local authority area over time, sourced from the HPI. The four 18 THE MARINERS sales between December 1996 and August 2012 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 August 1998 sale was for 33% above the HPI. So the extrapolation line tracks at 33% above the HPI over time, until the August 2012 sale, where it falls to 14% below the HPI. The line then continues to track at 14% below the HPI.

18 THE MARINERS might now be worth an estimated £127,840.
This is based on house price inflation of 66%, between August 2012 and April 2026, 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 66% inflationary increase is applied to the most recent sale price for 18 THE MARINERS of £77,000 on 31st August 2012. For the value to have increased from £77,000 to £127,840 over the fourteen years and four months to April 2026, the following assumptions must hold true:
