The below graph shows the average semi-detached house price in the Bromley local authority area over time, sourced from the HPI. The four 77 NEWSTEAD AVENUE sales between November 2001 and September 2020 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 April 2015 sale was for 7% below the HPI. So the extrapolation line tracks at 7% below the HPI over time, until the September 2020 sale, where it rises to 5% below the HPI. The line then continues to track at 5% below the HPI.

77 NEWSTEAD AVENUE might now be worth an estimated £644,543.
This is based on house price inflation of 24%, between September 2020 and July 2025, for semi-detached houses, in the Bromley local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
