20 CASTLE ROAD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Swansea local authority area over time, sourced from the HPI. The two 20 CASTLE ROAD sales from September 1996 and January 2022 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 September 1996 sale was for 9% above the HPI. So the extrapolation line tracks at 9% above the HPI over time, until the January 2022 sale, where it rises to 77% above the HPI. The line then continues to track at 77% above the HPI.
