The below graph shows the average detached house price in the Barnet local authority area over time, sourced from the HPI. The three 20 HILLSIDE sales between April 2000 and November 2011 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 November 2001 sale was for 3% below the HPI. So the extrapolation line tracks at 3% below the HPI over time, until the November 2011 sale, where it rises to 16% above the HPI. The line then continues to track at 16% above the HPI.
20 HILLSIDE might now be worth an estimated £1,805,922.
This is based on house price inflation of 65.7%, between November 2011 and February 2025, for detached houses, in the Barnet local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
