The below graph shows the average semi-detached house price in the Cardiff local authority area over time, sourced from the HPI. The three 15 WHITWORTH SQUARE sales between September 2006 and May 2018 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 December 2015 sale was for 37% above the HPI. So the extrapolation line tracks at 37% above the HPI over time, until the May 2018 sale, where it falls to 28% above the HPI. The line then continues to track at 28% above the HPI.
15 WHITWORTH SQUARE might now be worth an estimated £409,057.
