31 ALLEN 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 31 ALLEN CLOSE sales from November 1997 and August 2002 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 November 1997 sale was for 10% above the HPI. So the extrapolation line tracks at 10% above the HPI over time, until the August 2002 sale, where it falls to 12% below the HPI. The line then continues to track at 12% below the HPI.
