27 BLENHEIM 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 27 BLENHEIM AVENUE sales between October 2006 and December 2012 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 January 2010 sale was for 102% above the HPI. So the extrapolation line tracks at 102% above the HPI over time, until the December 2012 sale, where it rises to 146% above the HPI. The line then continues to track at 146% above the HPI.
