| Date | Price | HPI Price | Variation from HPI |

The below graph shows the average terraced house price in the Carmarthenshire local authority area over time, sourced from the HPI. The three 66 THE MARINERS sales between July 2000 and February 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 May 2002 sale was for 9% above the HPI. So the extrapolation line tracks at 9% above the HPI over time, until the February 2016 sale, where it rises to 10% above the HPI. The line then continues to track at 10% above the HPI.

66 THE MARINERS might now be worth an estimated £162,877.
This is based on house price inflation of 67.9%, between February 2016 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 67.9% inflationary increase is applied to the most recent sale price for 66 THE MARINERS of £97,000 on 22nd February 2016. For the value to have increased from £97,000 to £162,877 over the nine years and ten months to April 2026, the following assumptions must hold true:
