Closing Process

What happens during mortgage underwriting?

Short Answer

Mortgage underwriting is the process where a lender verifies your financial information and decides whether to approve your loan. The underwriter reviews your income, assets, credit, employment, and the property appraisal. They may request additional documents like updated pay stubs or bank statements. The process typically takes one to two weeks. Once approved, you receive a clear to close, meaning all conditions are satisfied and you can proceed to closing.

Underwriting is the most intensive part of the mortgage process. After you submit your application and documents, the underwriter reviews everything to ensure you meet the loan requirements. They verify your income through pay stubs, tax returns, and employer verification. They review your assets and bank statements to confirm you have enough funds for the down payment and closing costs. They check your credit report and score. They review the appraisal to ensure the property is worth the purchase price. During underwriting, the lender may request additional documents. This is called conditions. Common conditions include a letter explaining a large deposit, updated pay stubs, or verification of a recent address change. Responding to conditions quickly keeps the process moving. Once all conditions are satisfied, the underwriter issues a clear to close, which means the loan is approved and ready for closing. You should not make any major financial changes, such as opening new credit or changing jobs, during underwriting.

Underwriting can feel intrusive because the lender asks for a lot of documentation. But every request serves a purpose. The best thing you can do is respond to document requests the same day. I tell my clients to keep their lender's phone number handy and answer every call. A fast response can shave days off the underwriting timeline. If you have questions about what the underwriter needs, your lender can explain.
