11 ROBERT STREET 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 11 ROBERT STREET sales from January 2003 and July 2024 have been plotted on the graph.

For example, the January 2003 sale was for 47% below the HPI. So the extrapolation line tracks at 47% below the HPI over time, until the July 2024 sale, where it rises to 33% below the HPI.
