The below graph shows the average terraced house price in the Islington local authority area over time, sourced from the HPI. The three 70 THORNHILL ROAD sales between May 2007 and December 2020 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 July 2015 sale was for 112% above the HPI. So the extrapolation line tracks at 112% above the HPI over time, until the December 2020 sale, where it rises to 158% above the HPI. The line then continues to track at 158% above the HPI.

70 THORNHILL ROAD might now be worth an estimated £2,935,330.
