55 WILLIAM STREET 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 three 55 WILLIAM STREET sales between June 2001 and June 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 September 2016 sale was for 10% below the HPI. So the extrapolation line tracks at 10% below the HPI over time, until the June 2021 sale, where it falls to 20% below the HPI.
