The below graph shows the average terraced house price in the County Durham local authority area over time, sourced from the HPI. The three 20 STRATTON STREET sales between August 1995 and December 2015 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 January 2004 sale was for 24% below the HPI. So the extrapolation line tracks at 24% below the HPI over time, until the December 2015 sale, where it falls to 45% below the HPI. The line then continues to track at 45% below the HPI.

20 STRATTON STREET might now be worth an estimated £62,268.
This is based on house price inflation of 46.5%, between December 2015 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).
