The below graph shows the average semi-detached house price in the Cardiff local authority area over time, sourced from the HPI. The two 670 NEWPORT ROAD sales from September 2007 and May 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 September 2007 sale was for 34% above the HPI. So the extrapolation line tracks at 34% above the HPI over time, until the May 2015 sale, where it falls to 12% above the HPI. The line then continues to track at 12% above the HPI.
670 NEWPORT ROAD might now be worth an estimated £357,226.
