What Underwriters Really Care About When Reviewing Your Loan

January 09, 20266 min read

Let's be honest: the word "underwriter" probably makes you think of someone in a dark room with a magnifying glass, looking for reasons to deny your loan. But here's the truth: underwriters are actually on your team. Their job isn't to reject you; it's to make sure you're getting a loan you can comfortably afford.

After helping hundreds of Georgia families navigate the mortgage process, I've learned that understanding what underwriters care about removes 90% of the stress from getting approved. So let's pull back the curtain and see exactly what they're looking for.

The Big Picture: What Underwriters Really Want to Know

Every underwriter starts with three fundamental questions:

  1. Can you afford this payment? (Capacity)

  2. Will you actually make the payments? (Character)

  3. What happens if you can't pay? (Collateral)

Everything else flows from these core concerns. When you understand this, the entire process becomes much less mysterious.

Your Credit History: The Story You've Already Written

Your credit report is like a financial biography: it tells the story of how you've handled money over the years. But here's what many borrowers don't realize: underwriters aren't just looking at your credit score. They're reading between the lines.

What they love to see:

  • Consistent on-time payments across different types of credit

  • Credit balances well below your limits (under 30% is ideal)

  • A mix of credit types (credit cards, car loans, etc.) handled responsibly

  • Length of credit history (older accounts are gold)

What raises eyebrows:

  • Recent late payments (especially 30+ days)

  • Maxed-out credit cards

  • Collections or charge-offs

  • Multiple recent credit inquiries

Here's the good news: even imperfect credit can get approved. I've helped clients with credit scores in the 580s get fantastic loan terms by understanding exactly what underwriters need to see. The key is context: if there's a reason for past credit issues (medical bills, divorce, job loss), we can document that story.

Income Verification: Proving You Can Pay

This is where underwriters become detectives. They're not just confirming you have income; they're making sure it's stable, reliable, and likely to continue.

For W-2 employees, they want to see:

  • Pay stubs from the last 30 days

  • W-2s from the previous 2 years

  • Verification of Employment (VOE) form from your employer

  • Bank statements showing consistent deposits

For self-employed borrowers (my specialty in Georgia!), it's more complex:

  • 2 years of complete tax returns with all schedules

  • Year-to-date Profit & Loss statement

  • Business bank statements

  • CPA letter verifying income (sometimes)

Pro tip: If your income varies seasonally: like many real estate agents, contractors, or teachers in Georgia: we'll average it over 2 years. The underwriter wants to see the full picture, not just your slowest month.

Debt-to-Income Ratio: The Magic Number

Your debt-to-income ratio (DTI) is probably the most important number in your entire application. It's simply your total monthly debt payments divided by your gross monthly income.

Most conventional loans want to see:

  • Front-end ratio (just housing payment): Under 28%

  • Back-end ratio (all debt): Under 36%

But here's where it gets interesting: different loan programs have different limits:

  • FHA loans: Up to 43% back-end (sometimes higher with strong credit)

  • VA loans: No specific front-end limit, back-end typically 41%

  • USDA loans: 29% front-end, 41% back-end

According to recent data from Mortgage News Daily, lenders are being more flexible with DTI ratios when borrowers have strong credit scores and cash reserves. I've seen conventional loans approved at 45% DTI with compensating factors.

Employment Stability: Your Track Record

Underwriters want to see at least 2 years of stable employment history: but this doesn't mean you need to be at the same job for 2 years. They're looking for consistency in your field and income progression.

Green flags for employment:

  • Same line of work for 2+ years

  • Income that's stayed steady or increased

  • Full-time employment (vs. part-time or contract)

  • No unexplained gaps in employment

Yellow flags (not deal-breakers, but need explanation):

  • Job change in the last 2 years

  • Career change

  • Return to work after absence

  • Commission or bonus-based income

Recent job changes aren't automatically bad: especially if it's a promotion or move to better pay in the same field. I helped a nurse in Marietta get approved just 3 weeks after starting a new job because it was clearly a career advancement.

Assets and Reserves: Your Financial Cushion

Underwriters want to see that you have:

  1. Money for down payment and closing costs (and can prove where it came from)

  2. Reserves (cash left over after closing)

  3. Assets that could be liquidated if needed

They'll scrutinize:

  • Bank statements from the last 2-3 months

  • Investment account statements

  • Gift letters (if family is helping with down payment)

  • Large deposits (anything over $1,000 needs explanation)

Common issues I help clients resolve:

  • Cash deposits from side work (need documentation)

  • Transferred money between accounts (need paper trail)

  • Crypto or stock sales (need detailed transaction records)

  • Gift money (needs proper gift letter and donor documentation)

Property Appraisal: Making Sure the Numbers Work

The property secures your loan, so underwriters need to confirm it's worth what you're paying. The appraisal process examines:

  • Market value compared to similar recent sales

  • Property condition and any needed repairs

  • Market trends in the area

  • Unique factors that might affect value

According to recent analysis from ReVenture App, Georgia's market has seen interesting appraisal trends in 2025-2026, with some areas showing strength while others cool. This affects how conservative underwriters are being with property valuations.

If an appraisal comes in low, don't panic: we have options like requesting a reappraisal, providing additional comparables, or negotiating with the seller.

Red Flags That Slow Things Down (And How to Avoid Them)

Recent credit inquiries: Multiple credit pulls in the last 30-60 days raise questions. Shop for rates within a 14-day window to minimize impact.

Large unexplained deposits: Any bank deposit over $1,000 needs documentation. Keep receipts for everything!

New debt: Don't buy a car, open credit cards, or make large purchases during the mortgage process.

Job changes: If you must change jobs during the process, tell me immediately. We can usually work through it.

Undisclosed liabilities: Child support, alimony, or cosigned loans must be disclosed upfront.

The Human Element: Why Experience Matters

Here's what 15+ years in Georgia mortgage lending has taught me: every underwriter is different, and every loan tells a story. What gets approved with one underwriter might get questioned by another. That's why having an experienced loan officer who knows local underwriters and their preferences is invaluable.

I've built relationships with underwriters across Georgia, and I know:

  • Which ones are more flexible with DTI ratios

  • How to present borderline cases for best results

  • What documentation makes their job easier

  • How to address concerns before they become problems
