Why lenders sometimes move an application to manual underwriting

Automated underwriting systems (AUS) speed decisions but apply strict, rule-based thresholds. Manual underwriting gives a lender’s experienced underwriter discretion to evaluate the full financial story. That discretion lets them approve otherwise “marginal” applicants when clear compensating factors outweigh isolated negatives.

Why underwriters approve marginal files — the common reasons

  • Compensating factors: Strong cash reserves, steady employment, a low back-end debt-to-income ratio, or a large down payment can offset a low credit score. (See CFPB guidance on underwriting practices: https://www.consumerfinance.gov/)
  • Nontraditional credit history: Rent, utilities, and phone payments or business cash flow can demonstrate payment reliability when traditional credit is thin. Our guide on alternative income covers this in detail: Preparing for Loan Underwriting as a Self-Employed Applicant (https://finhelp.io/glossary/preparing-for-loan-underwriting-as-a-self-employed-applicant/).
  • One-time or resolved issues: Medical bills, temporary unemployment, or a short credit lapse that’s well documented and followed by a recovery pattern can be judged leniently.
  • Strong recent credit behavior: New, positive trade lines or on-time payments after previous delinquencies show improved risk.
  • Documented explanations and corroboration: Detailed, honest written explanations plus bank statements, tax returns, and third-party verifications can tip the decision.

A practical example from my experience

In my practice I worked with an applicant whose credit score fell after a short business failure two years earlier. Their tax returns and bank statements showed steady income recovery, and they’d rebuilt savings. The manual underwriter approved the loan because the applicant demonstrated ongoing cash flow and reduced leverage — compensating factors the AUS could not fully account for.

When manual underwriting is available and who offers it

Not every lender offers manual underwriting; availability depends on product type and lender policy. Community banks and credit unions are more likely to use it, and certain government-backed programs allow manual underwriting in specific cases. Lenders vary widely — read “Loan Approval: What Is Manual Underwriting?” for more background (https://finhelp.io/glossary/loan-approval-what-is-manual-underwriting/).

Tips to improve approval chances under manual underwriting

  1. Prepare complete documentation: recent bank statements, two years of tax returns (if self-employed), pay stubs, and explanations for any derogatory items. See our checklist: Preparing for Loan Underwriting as a Self-Employed Applicant (https://finhelp.io/glossary/preparing-for-loan-underwriting-as-a-self-employed-applicant/).
  2. Highlight compensating factors: emphasize savings, job stability, new credit trends, or a larger down payment.
  3. Provide clear written explanations: short, factual statements about past credit events with supporting documents.
  4. Correct report errors beforehand: disputes and corrections to your credit report remove avoidable red flags.
  5. Work with a lender who understands nontraditional income: community lenders or specialized mortgage brokers often have more flexibility.

What to expect in timing and cost

Manual underwriting takes longer — days to weeks — because each file requires detailed review. Some lenders may charge higher fees for higher-risk loans, while others absorb costs to build relationships; always ask upfront.

Common misconceptions

  • Manual underwriting is “easier”: Not true. It’s more nuanced; underwriters still look for overall creditworthiness and may deny marginal cases lacking compensating factors.
  • Manual underwriting guarantees approval: It only provides a discretionary path — approval still depends on the underwriter’s assessment and lender policy.
