5 BLACKHILL ROAD Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Swansea local authority area over time, sourced from the HPI. The two 5 BLACKHILL ROAD sales from October 2004 and June 2025 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 October 2004 sale was for 12% below the HPI. So the extrapolation line tracks at 12% below the HPI over time, until the June 2025 sale, where it falls to 42% below the HPI. The line then continues to track at 42% below the HPI.

What might 5 BLACKHILL ROAD be worth now?
