The below graph shows the average terraced house price in the Chichester local authority area over time, sourced from the HPI. The two NEW MILL COTTAGE sales from March 2014 and May 2015 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 2014 sale was for 37% above the HPI. So the extrapolation line tracks at 37% above the HPI over time, until the May 2015 sale, which was also at 37% above the HPI.

NEW MILL COTTAGE might now be worth an estimated £498,117.
This is based on house price inflation of 42.3%, between May 2015 and August 2025, for terraced houses, in the Chichester local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
