7 DULAS ISLAND CLOSE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Caerphilly local authority area over time, sourced from the HPI. The three 7 DULAS ISLAND CLOSE sales between February 2014 and March 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 April 2017 sale was for 19% above the HPI. So the extrapolation line tracks at 19% above the HPI over time, until the March 2025 sale, where it falls to 15% above the HPI. The line then continues to track at 15% above the HPI.
