7 HEOL Y WERN Price Paid vs. HPI Average

The below graph shows the average detached house price in the Cardiff local authority area over time, sourced from the HPI. The two 7 HEOL Y WERN sales from January 1997 and September 2007 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 January 1997 sale was for 17% below the HPI. So the extrapolation line tracks at 17% below the HPI over time, until the September 2007 sale, where it rises to 15% below the HPI. The line then continues to track at 15% below the HPI.

What might 7 HEOL Y WERN be worth now?
