9 THE SQUARE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Sutton local authority area over time, sourced from the HPI. The four 9 THE SQUARE sales between May 2006 and January 2023 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 2018 sale was for 3% below the HPI. So the extrapolation line tracks at 3% below the HPI over time, until the January 2023 sale, where it falls to 11% below the HPI. The line then continues to track at 11% below the HPI.

What might 9 THE SQUARE be worth now?

9 THE SQUARE might now be worth an estimated £882,603.

This is based on house price deflation of 4.6%, between January 2023 and December 2024, for detached houses, in the Sutton local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 4.6% deflationary decrease is applied to the most recent sale price for 9 THE SQUARE of £925,000 on 12th January 2023. For the value to have decreased from £925,000 to £882,603 over the one month to December 2024, the following assumptions must hold true:

• The value of 9 THE SQUARE has moved in line with the HPI for detached houses in the Sutton local authority area.

• The size, condition, and specification of 9 THE SQUARE has not materially changed since January 2023.
