12 TALL TREES 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 12 TALL TREES sales from February 2015 and February 2025 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 2015 sale was for 12% below the HPI. So the extrapolation line tracks at 12% below the HPI over time, until the February 2025 sale, where it rises to 5% above the HPI. The line then continues to track at 5% above the HPI.

What might 12 TALL TREES be worth now?

12 TALL TREES might now be worth an estimated £855,366.

This is based on house price inflation of 2.4%, between February 2025 and October 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 2.4% inflationary increase is applied to the most recent sale price for 12 TALL TREES of £835,000 on 28th February 2025. For the value to have increased from £835,000 to £855,366 over the four months to October 2025, the following assumptions must hold true:

• The value of 12 TALL TREES has moved in line with the HPI for detached houses in the North Hertfordshire local authority area.
• The February 2025 sale price of £835,000 represented a fair market value for the property.
• The size, condition, and specification of 12 TALL TREES has not materially changed since February 2025.
