23 WILLIAM GAMMON DRIVE 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 23 WILLIAM GAMMON DRIVE sales from December 2005 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 December 2005 sale was for 27% above the HPI. So the extrapolation line tracks at 27% above the HPI over time, until the January 2023 sale, where it falls to 3% below the HPI. The line then continues to track at 3% below the HPI.
