25 TREELANDS Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Darlington local authority area over time, sourced from the HPI. The three 25 TREELANDS sales between January 1996 and March 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 1996 sale was for 38% below the HPI. So the extrapolation line tracks at 38% below the HPI over time, until the March 2025 sale, where it rises to 39% above the HPI. The line then continues to track at 39% above the HPI.

What might 25 TREELANDS be worth now?

25 TREELANDS might now be worth an estimated £247,965.

This is based on house price inflation of 3.3%, between March 2025 and August 2025, for semi-detached houses, in the Darlington local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 3.3% inflationary increase is applied to the most recent sale price for 25 TREELANDS of £240,000 on 14th March 2025. For the value to have increased from £240,000 to £247,965 over the seven months to August 2025, the following assumptions must hold true:

• The value of 25 TREELANDS has moved in line with the HPI for semi-detached houses in the Darlington local authority area.
• The March 2025 sale price of £240,000 represented a fair market value for the property.
• The size, condition, and specification of 25 TREELANDS has not materially changed since March 2025.
