31 ONSLOW AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Sutton local authority area over time, sourced from the HPI. The two 31 ONSLOW AVENUE sales from September 2002 and February 2014 have been plotted on the graph.

For example, the September 2002 sale was for 3% below the HPI. So the extrapolation line tracks at 3% below the HPI over time, until the February 2014 sale, where it rises to 22% above the HPI. The line then continues to track at 22% above the HPI.
