The Mortgage Underwriter evaluates residential mortgage loan applications submitted by Third-Party Originators (TPOs) to ensure compliance with agency, investor, and internal underwriting guidelines — assessing borrower creditworthiness, capacity, collateral, and overall risk to determine loan eligibility across conventional, jumbo, and non-QM loans. Underwriters work with Automated Underwriting Systems (AUS) such as Desktop Underwriter (DU) for Fannie Mae and Loan Prospector (LP) for Freddie Mac, and perform manual underwriting.
