26 THE ISLAND Price Paid vs. HPI Average

The below graph shows the average detached house price in the Buckinghamshire local authority area over time, sourced from the HPI. The two 26 THE ISLAND sales from November 1997 and February 2024 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 November 1997 sale was for 55% below the HPI. So the extrapolation line tracks at 55% below the HPI over time, until the February 2024 sale, where it falls to 57% below the HPI. The line then continues to track at 57% below the HPI.

What might 26 THE ISLAND be worth now?

26 THE ISLAND might now be worth an estimated £362,197.

This is based on house price inflation of 3.5%, between February 2024 and February 2025, for detached houses, in the Buckinghamshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 3.5% inflationary increase is applied to the most recent sale price for 26 THE ISLAND of £350,000 on 5th February 2024. For the value to have increased from £350,000 to £362,197 over the one year to February 2025, the following assumptions must hold true:

• The value of 26 THE ISLAND has moved in line with the HPI for detached houses in the Buckinghamshire local authority area.
• The February 2024 sale price of £350,000 represented a fair market value for the property.
