The below graph shows the average detached house price in the Barnet local authority area over time, sourced from the HPI. The two 11 PORTSDOWN AVENUE sales from October 2011 and June 2021 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 2011 sale was for 9% below the HPI. So the extrapolation line tracks at 9% below the HPI over time, until the June 2021 sale, where it rises to 16% above the HPI. The line then continues to track at 16% above the HPI.

What might 11 PORTSDOWN AVENUE be worth now?

This is based on house price inflation of 6%, between June 2021 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).

The 6% inflationary increase is applied to the most recent sale price for 11 PORTSDOWN AVENUE of £1,700,000 on 9th June 2021. For the value to have increased from £1,700,000 to £1,802,256 over the four years and four months to February 2025, the following assumptions must hold true:
