8 PENTWYN AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Caerphilly local authority area over time, sourced from the HPI. The four 8 PENTWYN AVENUE sales between November 2009 and November 2022 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 2021 sale was for 14% above the HPI. So the extrapolation line tracks at 14% above the HPI over time, until the November 2022 sale, where it falls to 7% above the HPI.
