13 CLOS GWASTIR 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 13 CLOS GWASTIR sales between November 1996 and March 2021 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 2000 sale was for 98% above the HPI. So the extrapolation line tracks at 98% above the HPI over time, until the March 2021 sale, where it falls to 78% above the HPI. The line then continues to track at 78% above the HPI.
