71 WARRENGATE 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 two 71 WARRENGATE ROAD sales from January 1997 and June 2021 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 January 1997 sale was for 4% below the HPI. So the extrapolation line tracks at 4% below the HPI over time, until the June 2021 sale, where it falls to 7% below the HPI. The line then continues to track at 7% below the HPI.

What might 71 WARRENGATE ROAD be worth now?
