The below graph shows the average semi-detached house price in the Cardiff local authority area over time, sourced from the HPI. The two 47 HEOL HIR sales from February 2018 and May 2026 have been plotted on the graph.

For example, the February 2018 sale was for 13% above the HPI. So the extrapolation line tracks at 13% above the HPI over time, until the May 2026 sale, where it rises to 66% above the HPI.
