Quick Answer
Once you've submitted your documents, an underwriter checks everything against the lender's guidelines, including your debt-to-income ratio, credit history, and the appraisal. Underwriting is often the step that decides whether your loan moves toward closing on schedule.

What an Underwriter Actually Checks
An underwriter verifies the documents you've provided, income, bank statements, tax returns, and credit history, and confirms they match the loan program's requirements. They also review the appraisal to make sure the property supports the loan amount, and check your loan-to-value ratio against program limits.
It's common for an underwriter to come back with conditions, a request for a specific document, an updated pay stub, or an explanation letter for a large deposit, before issuing final approval.
Staying On Track During Underwriting
Because underwriters are re-checking your financial picture right up to closing, lenders generally advise against opening new credit, changing jobs, or making large purchases while a loan is in underwriting. Even small changes can trigger extra scrutiny or delay your closing date.
Responding quickly to any underwriter requests is one of the best ways to keep your transaction moving toward its scheduled closing day.

Frequently Asked Questions — Underwriting
How long does underwriting take?
It varies by lender and loan complexity, but often takes anywhere from a few days to a couple of weeks.
What does 'clear to close' mean?
It means the underwriter has approved your loan with no outstanding conditions, and you're ready to schedule closing.
Can I still be denied after pre-approval?
Yes, pre-approval is preliminary. Underwriting is the deeper verification, and a loan can still be denied if something doesn't check out.
Should I avoid big purchases during underwriting?
Yes. Large purchases or new credit can change your debt-to-income ratio and jeopardize your approval.
