The below graph shows the average terraced house price in the County Durham local authority area over time, sourced from the HPI. The three 14 WINTERTON AVENUE sales between August 2002 and August 2011 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 2009 sale was for 11% below the HPI. So the extrapolation line tracks at 11% below the HPI over time, until the August 2011 sale, where it rises to 42% above the HPI. The line then continues to track at 42% above the HPI.

14 WINTERTON AVENUE might now be worth an estimated £164,677.
This is based on house price inflation of 43.8%, between August 2011 and July 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).
