The below graph shows the average terraced house price in the Caerphilly local authority area over time, sourced from the HPI. The two 15 TREM Y CASTELL sales from December 1996 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 December 1996 sale was for 81% above the HPI. So the extrapolation line tracks at 81% above the HPI over time, until the June 2021 sale, where it falls to 39% above the HPI. The line then continues to track at 39% above the HPI.
15 TREM Y CASTELL might now be worth an estimated £223,222.
