16 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 16 CASTLE ROAD sales from March 2016 and January 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 March 2016 sale was for 143% above the HPI. So the extrapolation line tracks at 143% above the HPI over time, until the January 2023 sale, where it rises to 156% above the HPI. The line then continues to track at 156% above the HPI.
