31 THE ISLAND Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Buckinghamshire local authority area over time, sourced from the HPI. The two 31 THE ISLAND sales from October 2001 and August 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 October 2001 sale was for 60% below the HPI. So the extrapolation line tracks at 60% below the HPI over time, until the August 2007 sale, where it rises to 51% below the HPI. The line then continues to track at 51% below the HPI.

What might 31 THE ISLAND be worth now?

31 THE ISLAND might now be worth an estimated £229,349.

This is based on house price inflation of 70.5%, between August 2007 and February 2025, for semi-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 70.5% inflationary increase is applied to the most recent sale price for 31 THE ISLAND of £134,500 on 24th August 2007. For the value to have increased from £134,500 to £229,349 over the eighteen years and six months to February 2025, the following assumptions must hold true:

• The value of 31 THE ISLAND has moved in line with the HPI for semi-detached houses in the Buckinghamshire local authority area.
• The August 2007 sale price of £134,500 represented a fair market value for the property.
