DEAN GRANGE 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 DEAN GRANGE sales from January 1995 and February 2007 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 January 1995 sale was for 411% above the HPI. So the extrapolation line tracks at 411% above the HPI over time, until the February 2007 sale, where it falls to 234% above the HPI. The line then continues to track at 234% above the HPI.

What might DEAN GRANGE be worth now?

DEAN GRANGE might now be worth an estimated £3,703,599.

This is based on house price inflation of 90.9%, between February 2007 and December 2024, 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 90.9% inflationary increase is applied to the most recent sale price for DEAN GRANGE of £1,940,000 on 28th February 2007. For the value to have increased from £1,940,000 to £3,703,599 over the sixteen years and two months to December 2024, the following assumptions must hold true:

• The value of DEAN GRANGE has moved in line with the HPI for detached houses in the Windsor and Maidenhead local authority area.
• The February 2007 sale price of £1,940,000 represented a fair market value for the property.
