The below graph shows the average terraced house price in the County Durham local authority area over time, sourced from the HPI. The three 12 THORNGATE PLACE sales between September 2006 and November 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 July 2017 sale was for 238% above the HPI. So the extrapolation line tracks at 238% above the HPI over time, until the November 2023 sale, where it rises to 283% above the HPI. The line then continues to track at 283% above the HPI.

12 THORNGATE PLACE might now be worth an estimated £433,250.
This is based on house price inflation of 10.2%, between November 2023 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).
