91 MARSH LANE 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 91 MARSH LANE sales from March 1997 and January 2012 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 March 1997 sale was for 88% above the HPI. So the extrapolation line tracks at 88% above the HPI over time, until the January 2012 sale, where it falls to 50% above the HPI. The line then continues to track at 50% above the HPI.

What might 91 MARSH LANE be worth now?

This is based on house price inflation of 66.6%, between January 2012 and December 2024, 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).

The 66.6% inflationary increase is applied to the most recent sale price for 91 MARSH LANE of £1,400,000 on 16th January 2012. For the value to have increased from £1,400,000 to £2,333,029 over the eleven years and one month to December 2024, the following assumptions must hold true:
