21 BOLTON AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Windsor and Maidenhead local authority area over time, sourced from the HPI. The two 21 BOLTON AVENUE sales from July 2012 and October 2020 have been plotted on the graph.

For example, the July 2012 sale was for 65% above the HPI. So the extrapolation line tracks at 65% above the HPI over time, until the October 2020 sale, where it rises to 76% above the HPI. The line then continues to track at 76% above the HPI.
