27 WILLIAM ALLEN LANE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Mid Sussex local authority area over time, sourced from the HPI. The two 27 WILLIAM ALLEN LANE sales from July 2002 and November 2017 have been plotted on the graph.

For example, the July 2002 sale was for 6% below the HPI. So the extrapolation line tracks at 6% below the HPI over time, until the November 2017 sale, where it rises to 3% below the HPI. The line then continues to track at 3% below the HPI.
