31 HEOL YNYS DDU 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 five 31 HEOL YNYS DDU sales between July 1998 and October 2014 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 2010 sale was for 54% above the HPI. So the extrapolation line tracks at 54% above the HPI over time, until the October 2014 sale, where it falls to 53% above the HPI. The line then continues to track at 53% above the HPI.

What might 31 HEOL YNYS DDU be worth now?
