The below graph shows the average semi-detached house price in the Harrow local authority area over time, sourced from the HPI. The two 23 WINDSOR ROAD sales from June 2009 and June 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 June 2009 sale was for 22% below the HPI. So the extrapolation line tracks at 22% below the HPI over time, until the June 2020 sale, where it rises to 17% below the HPI. The line then continues to track at 17% below the HPI.

23 WINDSOR ROAD might now be worth an estimated £555,411.
This is based on house price inflation of 21.4%, between June 2020 and May 2026, for semi-detached houses, in the Harrow local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
