The below graph shows the average terraced house price in the County Durham local authority area over time, sourced from the HPI. The three 9 THORNGATE PLACE sales between April 2005 and July 2020 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 April 2012 sale was for 175% above the HPI. So the extrapolation line tracks at 175% above the HPI over time, until the July 2020 sale, where it rises to 223% above the HPI. The line then continues to track at 223% above the HPI.

9 THORNGATE PLACE might now be worth an estimated £365,956.
This is based on house price inflation of 40.8%, between July 2020 and August 2025, for terraced 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).
