CYNLAS Price Paid vs. HPI Average

The below graph shows the average detached house price in the Gwynedd local authority area over time, sourced from the HPI. The two CYNLAS sales from December 2022 and April 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 December 2022 sale was for 74% above the HPI. So the extrapolation line tracks at 74% above the HPI over time, until the April 2026 sale, where it falls to 33% above the HPI. The line then continues to track at 33% above the HPI.
