The below graph shows the average terraced house price in the Swansea local authority area over time, sourced from the HPI. The four 11 CASTLE ROAD sales between March 1998 and March 2016 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 May 2010 sale was for 64% above the HPI. So the extrapolation line tracks at 64% above the HPI over time, until the March 2016 sale, where it rises to 74% above the HPI. The line then continues to track at 74% above the HPI.

11 CASTLE ROAD might now be worth an estimated £294,974.
This is based on house price inflation of 59.4%, between March 2016 and April 2026, for terraced houses, in the Swansea local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
