11 SHELLEY AVENUE 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 11 SHELLEY AVENUE sales from December 2004 and July 2006 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 December 2004 sale was for 5% above the HPI. So the extrapolation line tracks at 5% above the HPI over time, until the July 2006 sale, where it rises to 38% above the HPI. The line then continues to track at 38% above the HPI.

What might 11 SHELLEY AVENUE be worth now?
