4 PENN 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 4 PENN GREEN sales from March 1995 and September 1997 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 March 1995 sale was for 202% above the HPI. So the extrapolation line tracks at 202% above the HPI over time, until the September 1997 sale, where it rises to 220% above the HPI. The line then continues to track at 220% above the HPI.

What might 4 PENN GREEN be worth now?

4 PENN GREEN might now be worth an estimated £2,708,395.

This is based on house price inflation of 334%, between September 1997 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 334% inflationary increase is applied to the most recent sale price for 4 PENN GREEN of £624,000 on 29th September 1997. For the value to have increased from £624,000 to £2,708,395 over the 28 years and seven months to February 2025, the following assumptions must hold true:

• The value of 4 PENN GREEN has moved in line with the HPI for detached houses in the Buckinghamshire local authority area.
• The September 1997 sale price of £624,000 represented a fair market value for the property.
• The size, condition, and specification of 4 PENN GREEN has not materially changed since September 1997.
