What must the lender/underwriter establish about any income source used for repayment?

The correct focus is on the requirement that the lender or underwriter must establish that any income source used for repayment is stable and continuous for a minimum of three years after loan closing. This standard is important in the context of USDA Rural Housing Loans because it assesses the borrower's ability to consistently make mortgage payments over time.

Stable income is indicative of a reliable cash flow, which is critical for ensuring that the borrower can meet their financial obligations. A history of at least three years provides a clear picture of income consistency, allowing lenders to evaluate whether the borrower has a dependable source of funds, such as a long-term job, ongoing business revenue, or regular alimony or child support payments. This approach helps mitigate risk for both the lender and borrower, allowing for responsible lending practices.

In contrast, an income source that varies or is considered flexible may not provide the reliability needed for loan terms. Complex income situations might require additional documentation but do not inherently demonstrate stability. Moreover, income from part-time jobs can be included in the assessment, but it typically also needs to show a consistent pattern over time to be deemed acceptable for loan repayment purposes.
