THE TREEHOUSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Winchester local authority area over time, sourced from the HPI. The two THE TREEHOUSE sales from January 2004 and May 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 2004 sale was for 4% above the HPI. So the extrapolation line tracks at 4% above the HPI over time, until the May 2007 sale, where it rises to 10% above the HPI. The line then continues to track at 10% above the HPI.

What might THE TREEHOUSE be worth now?

THE TREEHOUSE might now be worth an estimated £875,247.

This is based on house price inflation of 79.4%, between May 2007 and December 2024, for detached houses, in the Winchester local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 79.4% inflationary increase is applied to the most recent sale price for THE TREEHOUSE of £488,000 on 11th May 2007. For the value to have increased from £488,000 to £875,247 over the sixteen years and five months to December 2024, the following assumptions must hold true:

• The value of THE TREEHOUSE has moved in line with the HPI for detached houses in the Winchester local authority area.
• The May 2007 sale price of £488,000 represented a fair market value for the property.
• The size, condition, and specification of THE TREEHOUSE has not materially changed since May 2007.
