11 THE DOWNS Price Paid vs. HPI Average

The below graph shows the average detached house price in the North Somerset local authority area over time, sourced from the HPI. The two 11 THE DOWNS sales from September 2003 and July 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 September 2003 sale was for 6% below the HPI. So the extrapolation line tracks at 6% below the HPI over time, until the July 2007 sale, where it rises to 2% below the HPI. The line then continues to track at 2% below the HPI.

What might 11 THE DOWNS be worth now?

11 THE DOWNS might now be worth an estimated £529,623.

This is based on house price inflation of 76.6%, between July 2007 and April 2026, for detached houses, in the North Somerset local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 76.6% inflationary increase is applied to the most recent sale price for 11 THE DOWNS of £299,950 on 19th July 2007. For the value to have increased from £299,950 to £529,623 over the nineteen years and three months to April 2026, the following assumptions must hold true:

• The value of 11 THE DOWNS has moved in line with the HPI for detached houses in the North Somerset local authority area.
• The July 2007 sale price of £299,950 represented a fair market value for the property.
• The size, condition, and specification of 11 THE DOWNS has not materially changed since July 2007.
