The below graph shows the average semi-detached house price in the Swansea local authority area over time, sourced from the HPI. The two 40 GREEN CLOSE sales from October 2001 and September 2015 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 October 2001 sale was for 78% above the HPI. So the extrapolation line tracks at 78% above the HPI over time, until the September 2015 sale, where it rises to 158% above the HPI. The line then continues to track at 158% above the HPI.

40 GREEN CLOSE might now be worth an estimated £545,397.
This is based on house price inflation of 64.8%, between September 2015 and April 2026, for semi-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 64.8% inflationary increase is applied to the most recent sale price for 40 GREEN CLOSE of £331,000 on 25th September 2015. For the value to have increased from £331,000 to £545,397 over the eleven years and five months to April 2026, the following assumptions must hold true:
