15 BROOKSIDE 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 15 BROOKSIDE sales between January 2000 and August 2025 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 May 2014 sale was for 28% below the HPI. So the extrapolation line tracks at 28% below the HPI over time, until the August 2025 sale, where it falls to 36% below the HPI. The line then continues to track at 36% below the HPI.

What might 15 BROOKSIDE be worth now?
