COED ISA 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 three COED ISA sales between January 2002 and April 2022 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 November 2011 sale was for 40% above the HPI. So the extrapolation line tracks at 40% above the HPI over time, until the April 2022 sale, where it falls to 37% above the HPI. The line then continues to track at 37% above the HPI.

What might COED ISA be worth now?

COED ISA might now be worth an estimated £429,013.

This is based on house price inflation of 11.4%, between April 2022 and February 2025, 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 11.4% inflationary increase is applied to the most recent sale price for COED ISA of £385,000 on 8th April 2022. For the value to have increased from £385,000 to £429,013 over the three years and two months to February 2025, the following assumptions must hold true:

• The value of COED ISA has moved in line with the HPI for detached houses in the Flintshire local authority area.
• The April 2022 sale price of £385,000 represented a fair market value for the property.
• The size, condition, and specification of COED ISA has not materially changed since April 2022.
