15 GWENDALE 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 three 15 GWENDALE sales between June 1999 and March 2024 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 August 2008 sale was for 42% below the HPI. So the extrapolation line tracks at 42% below the HPI over time, until the March 2024 sale, which was also at 42% below the HPI.

What might 15 GWENDALE be worth now?

15 GWENDALE might now be worth an estimated £662,430.

This is based on house price inflation of 4.6%, between March 2024 and June 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 4.6% inflationary increase is applied to the most recent sale price for 15 GWENDALE of £633,000 on 21st March 2024. For the value to have increased from £633,000 to £662,430 over the nine months to June 2025, the following assumptions must hold true:

• The value of 15 GWENDALE has moved in line with the HPI for detached houses in the Windsor and Maidenhead local authority area.
• The March 2024 sale price of £633,000 represented a fair market value for the property.
