The below graph shows the average detached house price in the Vale of Glamorgan local authority area over time, sourced from the HPI. The two 6 DE SULLY CLOSE sales from April 2022 and May 2026 have been plotted on the graph.

For example, the April 2022 sale was for 32% below the HPI. So the extrapolation line tracks at 32% below the HPI over time, until the May 2026 sale, where it rises to 26% below the HPI.
