The underwriter is the person who signs off on your mortgage. Automated underwriting software reads the application first, but a human underwriter still confirms that every number entered matches a document, that the home qualifies, and that the loan meets the FHA, VA, USDA or Conventional rules it's written under. When an FHA loan is underwritten by hand, the person who signs off is a Direct Endorsement underwriter, registered with FHA to approve FHA loans on the lender's behalf.
What the underwriter checks
- Credit. The scores, payment history, collections and recent inquiries on the credit report, along with any letters you've written about them.
- Income. Pay stubs, W-2s or tax returns, plus a verification of employment, to confirm the income is stable and likely to continue.
- Savings. Bank statements showing the down payment, closing costs and any required reserves, including where large deposits and gifts came from.
- The home. The appraisal, the title commitment, the homeowners policy and the flood zone determination.
The underwriter then works out the debt-to-income ratio from the verified figures, which can differ from the numbers on the application.
When the underwriter's income differs from yours
Maria earns $24 an hour. At 40 hours a week she figures her income at $24 × 40 × 52 ÷ 12, or $4,160 a month. Her hours vary from week to week, though, so the underwriter averages what she has actually been paid. Her year-to-date earnings are $35,100 over nine months and her W-2 for last year shows $45,600.
| Income figure | Monthly amount | Total DTI with $2,150 in payments |
|---|---|---|
| Maria's estimate | $4,160.00 | 51.68% |
| Underwriter's average: ($35,100 + $45,600) ÷ 21 months | $3,842.86 | 55.95% |
The verified figure is $317.14 lower, and her ratio climbs to 55.95%. That still sits under FHA's 56.9% limit with an automated approval, so the loan stays on track. A buyer who ends up just over the line can pay off a small debt, lower the price slightly or add a co-signer whose income counts on FHA and Conventional loans.
Helping the underwriter say yes quickly
Send every page of every statement, including blank ones. Explain large deposits before you're asked, and keep a paper trail when money moves between accounts. Hold off on new credit, job changes and big purchases until after closing, since the underwriter re-checks credit and employment before the loan funds. When a condition arrives, answer it the same day.
