3A HILLSIDE WAY 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 two 3A HILLSIDE WAY sales from November 1997 and November 2023 have been plotted on the graph. A line has been extrapolated to show what the value of the property might have been over time, following each sale, had it maintained the same margin above or below the HPI (as a percentage). For example, the November 1997 sale was for 20% below the HPI. So the extrapolation line tracks at 20% below the HPI over time, until the November 2023 sale, where it falls to 26% below the HPI. The line then continues to track at 26% below the HPI.
