Which of the following would not be considered a "fixed" source of income?

The correct answer is the option referring to any source of income subject to adjustment by a verifiable cost of living adjustment (COLA) or current rate of interest. A fixed source of income is characterized by the stability it offers over time, providing a consistent amount that does not fluctuate.

Salary checks that remain the same amount every pay period are indeed considered a fixed source of income because the individual can expect this same amount regularly, which helps in budgeting and financial planning. This constancy makes it a reliable source for evaluating financial stability when qualifying for housing assistance or loans.

In contrast, sources of income tied to adjustments, such as those influenced by COLA or interest rates, may vary over time and are hence regarded as non-fixed. These types of income can change due to factors outside the individual’s control, such as economic conditions, making them less predictable for long-term financial planning. Therefore, they do not meet the criteria for a fixed source of income, highlighting the need for stability in financial assessments.
