17 THORNHILL AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Southampton local authority area over time, sourced from the HPI. The three 17 THORNHILL AVENUE sales between May 2000 and October 2009 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 February 2003 sale was for 21% below the HPI. So the extrapolation line tracks at 21% below the HPI over time, until the October 2009 sale, where it rises to 9% below the HPI. The line then continues to track at 9% below the HPI.
