17 CALDER AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Welwyn Hatfield local authority area over time, sourced from the HPI. The two 17 CALDER AVENUE sales from July 2002 and October 2011 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 July 2002 sale was for 33% above the HPI. So the extrapolation line tracks at 33% above the HPI over time, until the October 2011 sale, where it rises to 36% above the HPI.
