The below graph shows the average terraced house price in the Cardiff local authority area over time, sourced from the HPI. The two 27 ROBERT STREET sales from January 2007 and October 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 January 2007 sale was for 40% below the HPI. So the extrapolation line tracks at 40% below the HPI over time, until the October 2023 sale, where it rises to 35% below the HPI. The line then continues to track at 35% below the HPI.

27 ROBERT STREET might now be worth an estimated £169,259.
