12 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 12 COTSWOLD AVENUE sales between February 1998 and March 2018 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 2011 sale was for 119% above the HPI. So the extrapolation line tracks at 119% above the HPI over time, until the March 2018 sale, where it falls to 82% above the HPI. The line then continues to track at 82% above the HPI.
