18 THE GREEN 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 18 THE GREEN sales from February 2001 and January 2010 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 2001 sale was for 78% above the HPI. So the extrapolation line tracks at 78% above the HPI over time, until the January 2010 sale, where it falls to 54% above the HPI. The line then continues to track at 54% above the HPI.

What might 18 THE GREEN be worth now?

18 THE GREEN might now be worth an estimated £1,300,319.

This is based on house price inflation of 77.3%, between January 2010 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 77.3% inflationary increase is applied to the most recent sale price for 18 THE GREEN of £733,500 on 15th January 2010. For the value to have increased from £733,500 to £1,300,319 over the fourteen years and eleven months to February 2025, the following assumptions must hold true:

• The value of 18 THE GREEN has moved in line with the HPI for detached houses in the Buckinghamshire local authority area.
• The January 2010 sale price of £733,500 represented a fair market value for the property.
• The size, condition, and specification of 18 THE GREEN has not materially changed since January 2010.
