9 DONNE CLOSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the North Hertfordshire local authority area over time, sourced from the HPI. The five 9 DONNE CLOSE sales between August 1997 and January 2026 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 March 2015 sale was for 52% below the HPI. So the extrapolation line tracks at 52% below the HPI over time, until the January 2026 sale, where it rises to 47% below the HPI. The line then continues to track at 47% below the HPI.

What might 9 DONNE CLOSE be worth now?
