THE RED HOUSE 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 THE RED HOUSE sales from February 1998 and October 2015 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 February 1998 sale was for 103% above the HPI. So the extrapolation line tracks at 103% above the HPI over time, until the October 2015 sale, where it falls to 69% above the HPI. The line then continues to track at 69% above the HPI.

What might THE RED HOUSE be worth now?

THE RED HOUSE might now be worth an estimated £1,939,046.

This is based on house price inflation of 31.5%, between October 2015 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 31.5% inflationary increase is applied to the most recent sale price for THE RED HOUSE of £1,475,000 on 15th October 2015. For the value to have increased from £1,475,000 to £1,939,046 over the ten years and eight months to February 2025, the following assumptions must hold true:

• The value of THE RED HOUSE has moved in line with the HPI for detached houses in the Windsor and Maidenhead local authority area.
• The October 2015 sale price of £1,475,000 represented a fair market value for the property.
• The size, condition, and specification of THE RED HOUSE has not materially changed since October 2015.
