What Triggers Manual Underwriting?

When a loan is submitted, the loan officer runs it through an automated underwriting system. DU and LP analyze credit score, income, assets, loan type, and dozens of other data points against a risk model and issue a finding. An Approve/Eligible finding means the loan meets automated guidelines and can close without manual review. A Refer or Caution finding means the system cannot confidently approve the file and it must be reviewed manually by a human underwriter.

The most common triggers are: no traditional credit score or a thin credit file with fewer than three tradelines; recent major derogatory events such as bankruptcies, foreclosures, or short sales still within guideline waiting periods; debt-to-income ratios at the outer edge of program limits; income that is inconsistent, non-traditional, or difficult for the system to model; and loan-to-value ratios that push the system's risk tolerance. A borrower can have strong income and a clean payment history but still receive a Refer finding if their credit profile is too thin for the system to evaluate confidently.

Under FHA manual underwriting, the standard maximum front-end DTI is 31% and back-end is 43%. These are tighter than the automated guidelines that allow up to 57% in some cases. However, documented compensating factors can expand these limits. With one compensating factor, FHA allows 37/47%. With two, 40/50%. Eligible compensating factors include: verified and documented cash reserves equal to at least three months of PITI payments, minimal payment shock (new payment is not significantly higher than current housing expense), no discretionary debt (credit cards paid in full monthly), and additional income not used for qualifying. The stronger the compensating factors, the more flexibility the manual underwriter has.

Borrowers without a traditional credit score can be manually underwritten using non-traditional credit references. FHA allows lenders to establish a credit history from rental payments, utility bills, insurance premiums, and other regular payment obligations. Twelve months of on-time payments on at least two to four non-traditional accounts can satisfy the credit history requirement. The file is then manually underwritten with the DTI and reserve requirements that apply. This is a common path for borrowers who have always paid cash or who have avoided credit products on principle.

VA loans can also be manually underwritten and the VA's residual income requirement actually makes VA one of the more forgiving programs for manual files. VA manual underwriting uses residual income as a key compensating factor. A veteran with a high DTI who comfortably meets or exceeds the VA residual income threshold for their family size and region has a meaningful compensating factor that supports approval. Dan's experience with VA underwriting means he knows how to structure the compensating factor analysis before submission.
