Which of the following factors can a credit union consider regarding "protected income" disclosed by an applicant?

The consideration of the length of time payments have been received as a factor in evaluating "protected income" is essential for a credit union. This is because consistent and stable income over time indicates reliability and support for the applicant's ability to meet repayment obligations. Lenders look for evidence of ongoing income sources, as they suggest financial stability. For instance, if an applicant has been receiving a particular form of protected income, such as alimony or disability payments, for an extended duration, it may signal that this income is a reliable source they can depend on.

In contrast, factors like family background or marital status of the payor, while potentially relevant in other contexts, may not provide direct insight into the stability or reliability of the income itself. Similarly, a recent credit score can provide a snapshot of an applicant's creditworthiness but does not directly correlate with the nature or sustainability of protected income. Thus, the focus on the length of time payments have been received is justified and relevant in assessing financial responsibility and the viability of income sources in lending decisions.
