21 COTSWOLD AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Ipswich local authority area over time, sourced from the HPI. The three 21 COTSWOLD AVENUE sales between November 2001 and July 2007 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 2002 sale was for 37% above the HPI. So the extrapolation line tracks at 37% above the HPI over time, until the July 2007 sale, where it rises to 53% above the HPI. The line then continues to track at 53% above the HPI.
