The lender will typically submit the application package to an automated underwriting system that will provide the lender with the necessary documentation needed for loan approval. In some cases, the lender may also manually underwrite an application package.
The lender's processor reviews the credit reports and documentation to verify your employment, debts, and payment histories. If there are unacceptable late payments, collections, judgments, etc., the processor requests a written explanation from you. The processor also reviews the appraisal and survey and checks for property issues that may affect final loan approval. The processor's job is to put together an entire application package for the lender's underwriter.
