10 SPEEDWELL CLOSE 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 10 SPEEDWELL CLOSE sales from June 2007 and August 2009 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 June 2007 sale was for 25% above the HPI. So the extrapolation line tracks at 25% above the HPI over time, until the August 2009 sale, where it falls to 23% below the HPI. The line then continues to track at 23% below the HPI.

What might 10 SPEEDWELL CLOSE be worth now?
