10 TWYNYFFALD ROAD Price Paid vs. HPI Average

The below graph shows the average terraced house price in the Caerphilly local authority area over time, sourced from the HPI. The two 10 TWYNYFFALD ROAD sales from October 2006 and June 2024 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 2006 sale was for 7% below the HPI. So the extrapolation line tracks at 7% below the HPI over time, until the June 2024 sale, where it falls to 9% below the HPI. The line then continues to track at 9% below the HPI.
