21A TRINITY PLACE Price Paid vs. HPI Average

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 three 21A TRINITY PLACE sales between August 1996 and September 2004 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 2000 sale was for 14% below the HPI. So the extrapolation line tracks at 14% below the HPI over time, until the September 2004 sale, where it rises to 1% below the HPI. The line then continues to track at 1% below the HPI.

What might 21A TRINITY PLACE be worth now?

This is based on house price inflation of 124.5%, between September 2004 and February 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 124.5% inflationary increase is applied to the most recent sale price for 21A TRINITY PLACE of £273,000 on 7th September 2004. For the value to have increased from £273,000 to £613,011 over the 21 years and seven months to February 2025, the following assumptions must hold true:

• The value of 21A TRINITY PLACE has moved in line with the HPI for semi-detached houses in the Windsor and Maidenhead local authority area.
• The September 2004 sale price of £273,000 represented a fair market value for the property.
