Mortgage Underwriting: What Lenders Review

Mortgage underwriting is the lender’s review of whether a loan meets applicable requirements. It evaluates both the borrower and property; a pre-approval or conditional approval does not guarantee the final decision.

Income, employment and debt

The lender verifies eligible income and reviews its history and expected continuance under the selected guidelines. Salary, variable income and self-employment can require different records. Monthly housing costs and other obligations matter alongside income. The lender may evaluate debt-to-income or other repayment measures, rather than income stability alone.

Assets and credit

Account statements and other records help verify funds for the down payment, closing expenses and required reserves. Gifts, transfers and large deposits may need documentation of an acceptable source. Credit review includes payment history, balances and other obligations as well as applicable score requirements. Explain changes promptly and provide complete requested records.

Property and final conditions

The lender reviews value, condition, title and insurance as required by the program. An appraisal estimates value and does not replace an inspection or guarantee the purchase price. Conditional approval identifies requirements still to be met. Employment, credit or assets may be rechecked before closing; ask your mortgage professional what remains and avoid assuming documents received or signed mean the loan has funded.
