44 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 four 44 BLENHEIM AVENUE sales between August 2006 and April 2014 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 2009 sale was for 95% above the HPI. So the extrapolation line tracks at 95% above the HPI over time, until the April 2014 sale, where it falls to 51% above the HPI. The line then continues to track at 51% above the HPI.
