The below graph shows the average detached house price in the Cardiff local authority area over time, sourced from the HPI. The two 20 TY GWYN GARDENS sales from July 2014 and September 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 July 2014 sale was for 122% above the HPI. So the extrapolation line tracks at 122% above the HPI over time, until the September 2018 sale, where it falls to 103% above the HPI. The line then continues to track at 103% above the HPI.
20 TY GWYN GARDENS might now be worth an estimated £1,053,804.
