The below graph shows the average semi-detached house price in the Caerphilly local authority area over time, sourced from the HPI. The three 21 COMMERCIAL ROAD sales between January 2005 and February 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 November 2006 sale was for 25% above the HPI. So the extrapolation line tracks at 25% above the HPI over time, until the February 2025 sale, where it falls to 15% below the HPI. The line then continues to track at 15% below the HPI.
