8 TREM Y GARTH Price Paid vs. HPI Average
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 8 TREM Y GARTH sales from November 1998 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 November 1998 sale was for 23% below the HPI. So the extrapolation line tracks at 23% below the HPI over time, until the June 2004 sale, where it rises to 20% below the HPI. The line then continues to track at 20% below the HPI.
