12 GARDEN 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 12 GARDEN ROAD sales from October 2020 and October 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 October 2020 sale was for 41% below the HPI. So the extrapolation line tracks at 41% below the HPI over time, until the October 2023 sale, where it rises to 31% below the HPI. The line then continues to track at 31% below the HPI.

What might 12 GARDEN ROAD be worth now?
