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 two 20 ALWYN ROAD sales from July 2018 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 July 2018 sale was for 38% below the HPI. So the extrapolation line tracks at 38% below the HPI over time, until the July 2020 sale, where it rises to 15% below the HPI. The line then continues to track at 15% below the HPI.
20 ALWYN ROAD might now be worth an estimated £522,159.

The 25.8% inflationary increase is applied to the most recent sale price for 20 ALWYN ROAD of £415,000 on 10th July 2020. For the value to have increased from £415,000 to £522,159 over the five years and five months to February 2025, the following assumptions must hold true:
