9 HIGH GREEN 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 two 9 HIGH GREEN sales from March 2000 and August 2024 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 March 2000 sale was for 151% above the HPI. So the extrapolation line tracks at 151% above the HPI over time, until the August 2024 sale, where it rises to 152% above the HPI. The line then continues to track at 152% above the HPI.

What might 9 HIGH GREEN be worth now?

9 HIGH GREEN might now be worth an estimated £592,010.

This is based on house price inflation of 6.7%, between August 2024 and December 2024, 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 6.7% inflationary increase is applied to the most recent sale price for 9 HIGH GREEN of £555,000 on 20th August 2024. For the value to have increased from £555,000 to £592,010 over the eight months to December 2024, the following assumptions must hold true:

• The value of 9 HIGH GREEN has moved in line with the HPI for detached houses in the County Durham local authority area.
• The August 2024 sale price of £555,000 represented a fair market value for the property.
• The size, condition, and specification of 9 HIGH GREEN has not materially changed since August 2024.
