The below graph shows the average semi-detached house price in the Harlow local authority area over time, sourced from the HPI. The four 12 GLAN AVON MEWS sales between January 2002 and June 2022 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 2022 sale was for 54% above the HPI. So the extrapolation line tracks at 54% above the HPI over time, until the June 2022 sale, where it rises to 56% above the HPI. The line then continues to track at 56% above the HPI.

12 GLAN AVON MEWS might now be worth an estimated £647,271.
This is based on house price inflation of 1.1%, between June 2022 and August 2025, for semi-detached houses, in the Harlow local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
