257A HERONSWOOD ROAD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Welwyn Hatfield local authority area over time, sourced from the HPI. The three 257A HERONSWOOD ROAD sales between August 2010 and May 2023 have been plotted on the graph.

For example, the November 2016 sale was for 62% below the HPI. So the extrapolation line tracks at 62% below the HPI over time, until the May 2023 sale, where it falls to 65% below the HPI.
