9 CALVINIA CLOSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Basildon local authority area over time, sourced from the HPI. The two 9 CALVINIA CLOSE sales from September 1999 and March 2004 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 September 1999 sale was for 20% above the HPI. So the extrapolation line tracks at 20% above the HPI over time, until the March 2004 sale, where it falls to 15% below the HPI. The line then continues to track at 15% below the HPI.
