The below graph shows the average semi-detached house price in the Barnet local authority area over time, sourced from the HPI. The two 84 DERWENT AVENUE sales from January 1999 and December 2009 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 January 1999 sale was for 23% below the HPI. So the extrapolation line tracks at 23% below the HPI over time, until the December 2009 sale, where it rises to 19% below the HPI. The line then continues to track at 19% below the HPI.
84 DERWENT AVENUE might now be worth an estimated £665,920.
