Underwriting

The process where lenders evaluate your creditworthiness and determine if they'll approve your loan and at what terms.

Also known as: loan underwriting, mortgage underwriting

What You Need to Know

Underwriting is the lender's investigation phase—they dig into your finances to decide whether you're a good risk and what interest rate you deserve. It's like a financial background check.

What Underwriters Evaluate:

1. Credit Score & History:

  • FICO score (720+ excellent, <580 risky)
  • Payment history (late payments are red flags)
  • Credit utilization
  • Recent credit inquiries
  • Public records (bankruptcies, foreclosures)

2. Income & Employment:

  • W-2s from past 2 years
  • Recent pay stubs
  • Employment verification (they may call your employer!)
  • Self-employed: 2 years of tax returns
  • Income stability and consistency

3. Debt-to-Income Ratio (DTI):

  • Monthly debt payments ÷ gross monthly income
  • Under 36% ideal, 43% maximum for most mortgages
  • Includes proposed new mortgage payment

4. Assets & Reserves:

  • Down payment source (gift vs. savings)
  • Bank statements (2-3 months)
  • Investment accounts
  • Reserves for 2-6 months of mortgage payments

5. Property (for Mortgages):

  • Appraisal value (home must be worth the loan amount)
  • Property condition
  • Marketability/sellability

Underwriting Timeline:

  • Pre-qualification: Minutes to hours (soft credit check, rough estimate)
  • Pre-approval: 1-3 days (hard credit check, document review)
  • Final underwriting: 2-5 days (after offer accepted, full verification)

Common Underwriting Conditions: Things underwriters ask for before final approval:

  • Explanation of large bank deposits
  • Letter explaining employment gap
  • Proof of gift funds from family
  • Updated pay stubs (if process drags out)
  • Verification of debt payoff

Automated vs. Manual Underwriting:

Automated (Desktop Underwriter):

  • Algorithm-based decision
  • Minutes to hours
  • Used for straightforward borrowers (W-2 income, good credit)
  • Fannie Mae/Freddie Mac systems

Manual Underwriting:

  • Human reviews your file
  • Days to weeks
  • For complex situations: self-employed, credit issues, unique properties
  • More subjective, but allows explanations

What Can Derail Underwriting:

DON'T During Underwriting:

  • Open new credit cards
  • Finance a car purchase
  • Miss any bill payments
  • Change jobs
  • Make large cash deposits
  • Cosign a loan

All of these can tank your approval!

Underwriting Decision:

  • Approved: Congratulations, you get the loan
  • Approved with Conditions: Need to provide more documents
  • Suspended: Major issue, might be denied
  • Denied: No loan for you (credit issues, insufficient income, etc.)

After Approval: Even after "clear to close," underwriters do a final check 1-2 days before closing to verify nothing changed (employment, credit, etc.).
