9 DUNNS CLOSE 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 four 9 DUNNS CLOSE sales between September 1998 and May 2026 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 July 2008 sale was for 129% above the HPI. So the extrapolation line tracks at 129% above the HPI over time, until the May 2026 sale, where it falls to 55% above the HPI. The line then continues to track at 55% above the HPI.

What might 9 DUNNS CLOSE be worth now?
