The below graph shows the average semi-detached house price in the Harrow local authority area over time, sourced from the HPI. The two 20 SIDNEY ROAD sales from March 1997 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 March 1997 sale was for 9% below the HPI. So the extrapolation line tracks at 9% below the HPI over time, until the June 2020 sale, where it falls to 14% below the HPI. The line then continues to track at 14% below the HPI.

20 SIDNEY ROAD might now be worth an estimated £573,621.
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).
The 21.4% inflationary increase is applied to the most recent sale price for 20 SIDNEY ROAD of £472,500 on 11th June 2020. For the value to have increased from £472,500 to £573,621 over the six years and one month to May 2026, the following assumptions must hold true:
