Definition
Underwriting is the lender review process used to evaluate borrower, property, and loan risk before approval.
If you are comparing mortgage options, treat underwriting as one piece of the total cost and risk picture, not a standalone detail.
Why It Matters
It matters because underwriting can affect approval, conditions, documents, and closing timing.
Simple Example
An underwriter may request updated bank statements or explanations for large deposits.
How to Use This Term
When you see underwriting on a loan estimate, calculator result, or lender conversation, connect it to three practical questions: how it affects monthly payment, how it affects cash needed now, and how it affects flexibility later.
