The below graph shows the average detached house price in the Flintshire local authority area over time, sourced from the HPI. The three 11A GARDD EITHIN sales between January 1995 and September 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 July 2000 sale was for 2% below the HPI. So the extrapolation line tracks at 2% below the HPI over time, until the September 2025 sale, where it rises to 1% below the HPI. The line then continues to track at 1% below the HPI.

11A GARDD EITHIN might now be worth an estimated £305,959.
This is based on house price inflation of 2%, between September 2025 and May 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).
The 2% inflationary increase is applied to the most recent sale price for 11A GARDD EITHIN of £300,000 on 1st September 2025. For the value to have increased from £300,000 to £305,959 over the one year and four months to May 2026, the following assumptions must hold true:
