The below graph shows the average detached house price in the Flintshire local authority area over time, sourced from the HPI. The three 4 WILLIAMS CLOSE sales between November 1999 and March 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 July 2019 sale was for 9% below the HPI. So the extrapolation line tracks at 9% below the HPI over time, until the March 2026 sale, where it rises to 2% below the HPI. The line then continues to track at 2% below the HPI.

4 WILLIAMS CLOSE might now be worth an estimated £304,054.
This is based on house price inflation of 1.4%, between March 2026 and April 2026, for detached houses, in the Flintshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
