37 SWYN Y NANT 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 three 37 SWYN Y NANT sales between March 2003 and January 2019 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 August 2004 sale was for 40% above the HPI. So the extrapolation line tracks at 40% above the HPI over time, until the January 2019 sale, where it falls to 25% above the HPI. The line then continues to track at 25% above the HPI.
