The below graph shows the average detached house price in the North Hertfordshire local authority area over time, sourced from the HPI. The two FULLING MILL HOUSE sales from September 2007 and September 2014 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 September 2007 sale was for 216% above the HPI. So the extrapolation line tracks at 216% above the HPI over time, until the September 2014 sale, where it rises to 217% above the HPI. The line then continues to track at 217% above the HPI.
FULLING MILL HOUSE might now be worth an estimated £2,460,212.
This is based on house price inflation of 53.8%, between September 2014 and February 2025, for detached houses, in the North Hertfordshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
