18 HILLERSDON AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Barnet local authority area over time, sourced from the HPI. The two 18 HILLERSDON AVENUE sales from October 1995 and August 1998 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 October 1995 sale was for 13% below the HPI. So the extrapolation line tracks at 13% below the HPI over time, until the August 1998 sale, where it falls to 20% below the HPI. The line then continues to track at 20% below the HPI.

What might 18 HILLERSDON AVENUE be worth now?
