The below graph shows the average terraced house price in the Cardiff local authority area over time, sourced from the HPI. The two 100 JOHNSTON ROAD sales from January 1996 and October 2018 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 1996 sale was for 43% below the HPI. So the extrapolation line tracks at 43% below the HPI over time, until the October 2018 sale, where it rises to roughly the same level as the HPI. The line then continues to track in line with the HPI.
100 JOHNSTON ROAD might now be worth an estimated £255,578.
This is based on house price inflation of 34.5%, between October 2018 and June 2025, for terraced houses, in the Cardiff local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
