Underwriting

Underwriting

The lender’s detailed verification and risk assessment of your application. An underwriter reviews income, assets, credit history, appraisal, and title before issuing a final approval (or a conditional approval with remaining items to clear). This is where documentation gaps surface — which is why self-employed borrowers benefit from organizing their file before applying.

How does this affect your loan? Estimate self-employed qualifying income with the DTI calculator, or read the self-employed mortgage guide.
