19 QUEEN ANNE SQUARE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Cardiff local authority area over time, sourced from the HPI. The two 19 QUEEN ANNE SQUARE sales from September 2003 and July 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 September 2003 sale was for 83% above the HPI. So the extrapolation line tracks at 83% above the HPI over time, until the July 2025 sale, where it rises to 127% above the HPI. The line then continues to track at 127% above the HPI.
