Plain-English explanation
The LO explains program options, collects your documentation, and shepherds the loan through processing and underwriting to closing.
Why it matters
A knowledgeable LO can save you money and time by matching you to the right program and structure.
Where you may see it
- Loan application
- Loan Estimate
A real-world example
Your loan officer identifies that a 7/6 ARM may fit your timeline better than a 30-year fixed given your plan to move in six years.
Educational and illustrative only
A common misunderstanding
A loan officer is not the person who approves your loan — underwriters make that decision based on documentation.
