15 MANSION GARDENS 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 15 MANSION GARDENS sales from August 2019 and September 2024 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 August 2019 sale roughly matched the HPI. So the extrapolation line tracks roughly in line with the HPI over time, until the September 2024 sale, where it rises to 12% above the HPI.
