1 BANK MILL Price Paid vs. HPI Average

The below graph shows the average detached house price in the Dacorum local authority area over time, sourced from the HPI. The two 1 BANK MILL sales from October 2003 and May 2019 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 2003 sale was for 63% below the HPI. So the extrapolation line tracks at 63% below the HPI over time, until the May 2019 sale, where it rises to 9% below the HPI. The line then continues to track at 9% below the HPI.

What might 1 BANK MILL be worth now?

This is based on house price inflation of 21.1%, between May 2019 and February 2025, for detached houses, in the Dacorum local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
