12 BONNIE 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 two 12 BONNIE GROVE sales from June 1997 and October 2013 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 June 1997 sale was for 113% above the HPI. So the extrapolation line tracks at 113% above the HPI over time, until the October 2013 sale, where it falls to 72% above the HPI. The line then continues to track at 72% above the HPI.

What might 12 BONNIE GROVE be worth now?

12 BONNIE GROVE might now be worth an estimated £405,882.

This is based on house price inflation of 45%, between October 2013 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 45% inflationary increase is applied to the most recent sale price for 12 BONNIE GROVE of £280,000 on 18th October 2013. For the value to have increased from £280,000 to £405,882 over the twelve years and eight months to February 2025, the following assumptions must hold true:

• The value of 12 BONNIE GROVE has moved in line with the HPI for detached houses in the County Durham local authority area.
• The October 2013 sale price of £280,000 represented a fair market value for the property.
• The size, condition, and specification of 12 BONNIE GROVE has not materially changed since October 2013.
