The below graph shows the average detached house price in the Bexley local authority area over time, sourced from the HPI. The two 429 BLACKFEN ROAD sales from December 2009 and May 2021 have been plotted on the graph.

For example, the December 2009 sale was for 27% below the HPI. So the extrapolation line tracks at 27% below the HPI over time, until the May 2021 sale, where it falls to 30% below the HPI.
