THREE GREENS Price Paid vs. HPI Average

The below graph shows the average detached house price in the North Hertfordshire local authority area over time, sourced from the HPI. The two THREE GREENS sales from June 2002 and September 2004 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 June 2002 sale was for 15% above the HPI. So the extrapolation line tracks at 15% above the HPI over time, until the September 2004 sale, where it falls to 6% above the HPI. The line then continues to track at 6% above the HPI.

What might THREE GREENS be worth now?

THREE GREENS might now be worth an estimated £821,782.

This is based on house price inflation of 112.1%, between September 2004 and February 2025, for detached houses, in the North Hertfordshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 112.1% inflationary increase is applied to the most recent sale price for THREE GREENS of £387,500 on 1st September 2004. For the value to have increased from £387,500 to £821,782 over the 21 years and seven months to February 2025, the following assumptions must hold true:

• The value of THREE GREENS has moved in line with the HPI for detached houses in the North Hertfordshire local authority area.
• The September 2004 sale price of £387,500 represented a fair market value for the property.
• The size, condition, and specification of THREE GREENS has not materially changed since September 2004.
