FOUNDRY HOUSE 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 FOUNDRY HOUSE sales between May 1999 and July 2017 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 July 2007 sale was for 45% above the HPI. So the extrapolation line tracks at 45% above the HPI over time, until the July 2017 sale, which was also at 45% above the HPI.

What might FOUNDRY HOUSE be worth now?
