25 GRAIG Y MYNYDD 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 25 GRAIG Y MYNYDD sales from July 2001 and December 2001 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 2001 sale was for 24% above the HPI. So the extrapolation line tracks at 24% above the HPI over time, until the December 2001 sale, where it rises to 32% above the HPI. The line then continues to track at 32% above the HPI.
