20 STAG GREEN 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 three 20 STAG GREEN AVENUE sales between May 1996 and November 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 November 2004 sale was for 13% below the HPI. So the extrapolation line tracks at 13% below the HPI over time, until the November 2011 sale, where it rises to 3% above the HPI. The line then continues to track at 3% above the HPI.
