22 THE ISLAND Price Paid vs. HPI Average

The below graph shows the average detached house price in the Elmbridge local authority area over time, sourced from the HPI. The two 22 THE ISLAND sales from February 2002 and September 2021 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 2002 sale was for 48% below the HPI. So the extrapolation line tracks at 48% below the HPI over time, until the September 2021 sale, where it rises to 39% below the HPI. The line then continues to track at 39% below the HPI.

What might 22 THE ISLAND be worth now?

22 THE ISLAND might now be worth an estimated £892,758.

This is based on house price inflation of 0.3%, between September 2021 and December 2024, for detached houses, in the Elmbridge local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 0.3% inflationary increase is applied to the most recent sale price for 22 THE ISLAND of £890,000 on 30th September 2021. For the value to have increased from £890,000 to £892,758 over the two years and nine months to December 2024, the following assumptions must hold true:

• The value of 22 THE ISLAND has moved in line with the HPI for detached houses in the Elmbridge local authority area.
• The September 2021 sale price of £890,000 represented a fair market value for the property.
• The size, condition, and specification of 22 THE ISLAND has not materially changed since September 2021.
