The below graph shows the average terraced house price in the Cardiff local authority area over time, sourced from the HPI. The two 47 DIANA STREET sales from July 1999 and June 2004 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 1999 sale was for 42% above the HPI. So the extrapolation line tracks at 42% above the HPI over time, until the June 2004 sale, where it rises to 49% above the HPI. The line then continues to track at 49% above the HPI.
47 DIANA STREET might now be worth an estimated £382,160.
