The below graph shows the average terraced house price in the Barnet local authority area over time, sourced from the HPI. The four 343 LONG LANE sales between December 2000 and July 2017 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 2012 sale was for 33% above the HPI. So the extrapolation line tracks at 33% above the HPI over time, until the July 2017 sale, where it rises to 49% above the HPI. The line then continues to track at 49% above the HPI.

343 LONG LANE might now be worth an estimated £923,538.
