The below graph shows the average detached house price in the Welwyn Hatfield local authority area over time, sourced from the HPI. The two 231 HERONSWOOD ROAD sales from April 2012 and August 2024 have been plotted on the graph.

For example, the April 2012 sale was for 57% below the HPI. So the extrapolation line tracks at 57% below the HPI over time, until the August 2024 sale, where it rises to 52% below the HPI.
