The below graph shows the average terraced house price in the Swansea local authority area over time, sourced from the HPI. The four 4 COWPER CLOSE sales between March 1996 and September 2003 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 September 2000 sale was for 42% above the HPI. So the extrapolation line tracks at 42% above the HPI over time, until the September 2003 sale, where it falls to 21% above the HPI. The line then continues to track at 21% above the HPI.

4 COWPER CLOSE might now be worth an estimated £205,010.
This is based on house price inflation of 164.5%, between September 2003 and April 2026, for terraced houses, in the Swansea local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
