The below graph shows the average semi-detached house price in the Southampton local authority area over time, sourced from the HPI. The two 18 ROCKLEIGH ROAD sales from September 2011 and July 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 September 2011 sale was for 11% above the HPI. So the extrapolation line tracks at 11% above the HPI over time, until the July 2020 sale, where it rises to 22% above the HPI. The line then continues to track at 22% above the HPI.
18 ROCKLEIGH ROAD might now be worth an estimated £379,766.
This is based on house price inflation of 18.7%, between July 2020 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).
