3 BLACKTHORN COURT 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 3 BLACKTHORN COURT sales between December 1998 and March 2020 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 2004 sale was for 57% above the HPI. So the extrapolation line tracks at 57% above the HPI over time, until the March 2020 sale, where it falls to 55% above the HPI. The line then continues to track at 55% above the HPI.

What might 3 BLACKTHORN COURT be worth now?
