129 DIANA STREET Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Cardiff local authority area over time, sourced from the HPI. The two 129 DIANA STREET sales from August 1997 and April 2010 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 August 1997 sale was for 20% above the HPI. So the extrapolation line tracks at 20% above the HPI over time, until the April 2010 sale, where it rises to 46% above the HPI. The line then continues to track at 46% above the HPI.

What might 129 DIANA STREET be worth now?
