FHA Manual Underwriting Guide 2026: Complete DTI & Compensating Factor Rules

Everything you need to know about qualifying for an FHA loan when the automated system says "Refer" — including the latest DTI limits, compensating factors, and real success stories.

15 min readUpdated January 2026

If you've been told your FHA loan application received a "Refer" status from the Automated Underwriting System (AUS), don't panic. This doesn't mean you're denied — it means your file needs human review through manual underwriting. And with the right compensating factors, you may still qualify for an FHA loan with as little as 3.5% down.

Key Takeaways for 2026

  • FHA manual underwriting allows DTI up to 50% with two compensating factors
  • Minimum credit score of 500 (580+ for 3.5% down payment)
  • Non-traditional credit accepted for borrowers without FICO scores
  • Bankruptcy waiting period as short as 12 months for Chapter 13

What is FHA Manual Underwriting?

FHA manual underwriting is when a human underwriter reviews your loan application instead of relying solely on the Automated Underwriting System (AUS). When the computer can't approve your loan automatically, it returns a "Refer" status, signaling that a human needs to evaluate your complete financial picture.

Common reasons for manual underwriting include:

  • Thin credit file: Limited or no traditional credit history
  • High DTI ratios: Debt exceeds standard automated limits
  • Recent credit events: Bankruptcy, foreclosure, or short sale
  • Non-traditional credit: No FICO score available
  • Complex income: Self-employment or variable income sources

The good news? Manual underwriting isn't a denial — it's an opportunity for someone to look at the nuances of your situation that a computer algorithm might miss.

2026 FHA Manual Underwriting DTI Limits

Debt-to-income (DTI) ratio is one of the most important factors in FHA manual underwriting. FHA uses a tiered system where your allowable DTI increases based on the number of compensating factors you have.

FHA Manual Underwriting DTI Tiers
Maximum allowable ratios based on compensating factors
Compensating FactorsFront-End DTIBack-End DTI
No Compensating Factors31%43%
One Compensating Factor37%47%
Two+ Compensating Factors40%50%

How DTI is calculated:

  • Front-End DTI = Housing Payment ÷ Gross Monthly Income
  • Back-End DTI = (Housing + All Debts) ÷ Gross Monthly Income

For example, if you earn $8,000/month gross and your proposed housing payment is $2,400 with $800 in other monthly debts:

  • Front-End DTI = $2,400 ÷ $8,000 = 30%
  • Back-End DTI = ($2,400 + $800) ÷ $8,000 = 40%

FHA Compensating Factors Explained

Compensating factors are strengths in your financial profile that can offset higher DTI ratios. FHA recognizes five primary compensating factors:

Verified Cash Reserves

At least 3 months of mortgage payments in verified liquid assets (bank accounts, investments, retirement funds).

Significant Income Increase

Documented income increase of at least $100/month or 5% in the past 12 months.

Residual Income

Sufficient money remaining each month after all housing and debt obligations are paid.

Minimal Housing Increase

New payment is no more than $100 or 5% higher than current housing expense.

Strong Employment History

Continuous employment in same field for 2+ years with stable or increasing income.
