The below graph shows the average semi-detached house price in the Southampton local authority area over time, sourced from the HPI. The two 11 DOWNSIDE AVENUE sales from March 2021 and May 2023 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 2021 sale was for 6% above the HPI. So the extrapolation line tracks at 6% above the HPI over time, until the May 2023 sale, where it rises to 31% above the HPI. The line then continues to track at 31% above the HPI.
11 DOWNSIDE AVENUE might now be worth an estimated £406,488.
This is based on house price inflation of 1.6%, between May 2023 and February 2025, for semi-detached houses, in the Southampton local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
