The below graph shows the average detached house price in the Swansea local authority area over time, sourced from the HPI. The two 18 HEOL EITHRIM sales from December 2000 and April 2005 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 December 2000 sale was for 86% below the HPI. So the extrapolation line tracks at 86% below the HPI over time, until the April 2005 sale, where it rises to 73% below the HPI. The line then continues to track at 73% below the HPI.

18 HEOL EITHRIM might now be worth an estimated £88,676.
This is based on house price inflation of 84.7%, between April 2005 and April 2026, for detached houses, in the Swansea local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 84.7% inflationary increase is applied to the most recent sale price for 18 HEOL EITHRIM of £48,000 on 8th April 2005. For the value to have increased from £48,000 to £88,676 over the 21 years to April 2026, the following assumptions must hold true:
