1 GRANGESIDE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Darlington local authority area over time, sourced from the HPI. The two 1 GRANGESIDE sales from December 2019 and June 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 December 2019 sale was for 30% above the HPI. So the extrapolation line tracks at 30% above the HPI over time, until the June 2025 sale, where it rises to 104% above the HPI. The line then continues to track at 104% above the HPI.

What might 1 GRANGESIDE be worth now?

1 GRANGESIDE might now be worth an estimated £569,105.

This is based on house price inflation of 2.5%, between June 2025 and April 2026, for 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 2.5% inflationary increase is applied to the most recent sale price for 1 GRANGESIDE of £555,000 on 11th June 2025. For the value to have increased from £555,000 to £569,105 over the one year and two months to April 2026, the following assumptions must hold true:

• The value of 1 GRANGESIDE has moved in line with the HPI for detached houses in the Darlington local authority area.
• The June 2025 sale price of £555,000 represented a fair market value for the property.
• The size, condition, and specification of 1 GRANGESIDE has not materially changed since June 2025.
