18 SUNNY BANK TERRACE 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 18 SUNNY BANK TERRACE sales between November 2000 and September 2018 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 2006 sale was for 21% above the HPI. So the extrapolation line tracks at 21% above the HPI over time, until the September 2018 sale, where it rises to 26% above the HPI. The line then continues to track at 26% above the HPI.

What might 18 SUNNY BANK TERRACE be worth now?
