The below graph shows the average terraced house price in the Swansea local authority area over time, sourced from the HPI. The two 15 CATHERINE STREET sales from July 2000 and April 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 July 2000 sale was for 30% above the HPI. So the extrapolation line tracks at 30% above the HPI over time, until the April 2003 sale, where it rises to 36% above the HPI. The line then continues to track at 36% above the HPI.

15 CATHERINE STREET might now be worth an estimated £233,384.
