The below graph shows the average semi-detached house price in the Windsor and Maidenhead local authority area over time, sourced from the HPI. The four 21 SUMMERLEAZE ROAD sales between October 1996 and November 2019 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 May 2002 sale was for 24% above the HPI. So the extrapolation line tracks at 24% above the HPI over time, until the November 2019 sale, where it falls to 5% below the HPI. The line then continues to track at 5% below the HPI.
21 SUMMERLEAZE ROAD might now be worth an estimated £570,318.
This is based on house price inflation of 22%, between November 2019 and July 2025, for semi-detached houses, in the Windsor and Maidenhead local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 22% inflationary increase is applied to the most recent sale price for 21 SUMMERLEAZE ROAD of £467,500 on 5th November 2019. For the value to have increased from £467,500 to £570,318 over the six years and four months to July 2025, the following assumptions must hold true:
