21 CASTLE AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Windsor and Maidenhead local authority area over time, sourced from the HPI. The two 21 CASTLE AVENUE sales from November 2017 and May 2022 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 November 2017 sale was for 50% below the HPI. So the extrapolation line tracks at 50% below the HPI over time, until the May 2022 sale, where it rises to 3% below the HPI. The line then continues to track at 3% below the HPI.

What might 21 CASTLE AVENUE be worth now?

21 CASTLE AVENUE might now be worth an estimated £1,117,609.

This is based on house price inflation of 3%, between May 2022 and February 2025, for 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 3% inflationary increase is applied to the most recent sale price for 21 CASTLE AVENUE of £1,085,000 on 23rd May 2022. For the value to have increased from £1,085,000 to £1,117,609 over the three years and three months to February 2025, the following assumptions must hold true:

• The value of 21 CASTLE AVENUE has moved in line with the HPI for detached houses in the Windsor and Maidenhead local authority area.
• The May 2022 sale price of £1,085,000 represented a fair market value for the property.
