15 GELLI DDAEAR GOCH 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 15 GELLI DDAEAR GOCH sales between August 2011 and September 2025 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 October 2022 sale was for 47% above the HPI. So the extrapolation line tracks at 47% above the HPI over time, until the September 2025 sale, where it falls to 40% above the HPI. The line then continues to track at 40% above the HPI.
