The below graph shows the average semi-detached house price in the Denbighshire local authority area over time, sourced from the HPI. The five 4 MILL STREET sales between July 1999 and February 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 April 2023 sale was for 2% below the HPI. So the extrapolation line tracks at 2% below the HPI over time, until the February 2025 sale, where it rises to 14% above the HPI. The line then continues to track at 14% above the HPI.
