The below graph shows the average detached house price in the Rhondda Cynon Taf local authority area over time, sourced from the HPI. The two GRONGAER sales from September 2013 and March 2022 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 2013 sale was for 24% below the HPI. So the extrapolation line tracks at 24% below the HPI over time, until the March 2022 sale, where it rises to 44% above the HPI. The line then continues to track at 44% above the HPI.
