73 GLOUCESTER AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Bexley local authority area over time, sourced from the HPI. The three 73 GLOUCESTER AVENUE sales between November 2001 and October 2015 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 December 2003 sale was for 1% below the HPI. So the extrapolation line tracks at 1% below the HPI over time, until the October 2015 sale, where it falls to 4% below the HPI. The line then continues to track at 4% below the HPI.

What might 73 GLOUCESTER AVENUE be worth now?

This is based on house price inflation of 40%, between October 2015 and December 2024, for detached houses, in the Bexley local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 40% inflationary increase is applied to the most recent sale price for 73 GLOUCESTER AVENUE of £485,250 on 16th October 2015. For the value to have increased from £485,250 to £679,549 over the eight years and ten months to December 2024, the following assumptions must hold true:
