1 ALDER GROVE Price Paid vs. HPI Average

The below graph shows the average detached house price in the County Durham local authority area over time, sourced from the HPI. The three 1 ALDER GROVE sales between May 2005 and October 2023 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 January 2014 sale was for 3% above the HPI. So the extrapolation line tracks at 3% above the HPI over time, until the October 2023 sale, where it rises to 16% above the HPI. The line then continues to track at 16% above the HPI.

What might 1 ALDER GROVE be worth now?

1 ALDER GROVE might now be worth an estimated £273,021.

This is based on house price inflation of 9.2%, between October 2023 and February 2025, for detached houses, in the County Durham local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 9.2% inflationary increase is applied to the most recent sale price for 1 ALDER GROVE of £250,000 on 30th October 2023. For the value to have increased from £250,000 to £273,021 over the two years and eight months to February 2025, the following assumptions must hold true:

• The value of 1 ALDER GROVE has moved in line with the HPI for detached houses in the County Durham local authority area.
• The October 2023 sale price of £250,000 represented a fair market value for the property.
• The size, condition, and specification of 1 ALDER GROVE has not materially changed since October 2023.
