4 UPPER CASTLE VIEW 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 three 4 UPPER CASTLE VIEW sales between November 2011 and June 2021 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 2016 sale was for 140% above the HPI. So the extrapolation line tracks at 140% above the HPI over time, until the June 2021 sale, where it rises to 183% above the HPI. The line then continues to track at 183% above the HPI.
