ISLAND VIEW Price Paid vs. HPI Average

The below graph shows the average detached house price in the Flintshire local authority area over time, sourced from the HPI. The two ISLAND VIEW sales from February 2025 and November 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 February 2025 sale was for 59% below the HPI. So the extrapolation line tracks at 59% below the HPI over time, until the November 2025 sale, where it rises to 9% above the HPI. The line then continues to track at 9% above the HPI.

What might ISLAND VIEW be worth now?

ISLAND VIEW might now be worth an estimated £337,691.

This is based on house price inflation of 0.1%, between November 2025 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).

The 0.1% inflationary increase is applied to the most recent sale price for ISLAND VIEW of £337,500 on 24th November 2025. For the value to have increased from £337,500 to £337,691 over the one year and seven months to April 2026, the following assumptions must hold true:

• The value of ISLAND VIEW has moved in line with the HPI for detached houses in the Flintshire local authority area.

• The size, condition, and specification of ISLAND VIEW has not materially changed since November 2025.
