The below graph shows the average detached house price in the St Albans local authority area over time, sourced from the HPI. The two 49 COLDHARBOUR LANE sales from May 1999 and February 2021 have been plotted on the graph.

For example, the May 1999 sale was for 41% below the HPI. So the extrapolation line tracks at 41% below the HPI over time, until the February 2021 sale, where it rises to 36% below the HPI.
