28 MERTHYR AVENUE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Portsmouth local authority area over time, sourced from the HPI. The two 28 MERTHYR AVENUE sales from August 2003 and September 2014 have been plotted on the graph.

For example, the August 2003 sale was for 54% above the HPI. So the extrapolation line tracks at 54% above the HPI over time, until the September 2014 sale, where it falls to 48% above the HPI. The line then continues to track at 48% above the HPI.
