The below graph shows the average detached house price in the Welwyn Hatfield local authority area over time, sourced from the HPI. The two 16 HARMER GREEN LANE sales from February 2003 and September 2021 have been plotted on the graph.

For example, the February 2003 sale was for 61% below the HPI. So the extrapolation line tracks at 61% below the HPI over time, until the September 2021 sale, where it rises to 43% below the HPI.
