The below graph shows the average terraced house price in the Barnet local authority area over time, sourced from the HPI. The six 150 LONG LANE sales between September 1995 and October 2019 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 2014 sale was for 1% below the HPI. So the extrapolation line tracks at 1% below the HPI over time, until the October 2019 sale, where it rises to 3% above the HPI. The line then continues to track at 3% above the HPI.

150 LONG LANE might now be worth an estimated £640,296.
This is based on house price inflation of 10.6%, between October 2019 and July 2025, for terraced houses, in the Barnet local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 10.6% inflationary increase is applied to the most recent sale price for 150 LONG LANE of £579,000 on 3rd October 2019. For the value to have increased from £579,000 to £640,296 over the six years and three months to July 2025, the following assumptions must hold true:
