What Credit Score Do You Need for a USDA Loan?
USDA itself sets no minimum credit score, but most lenders require 640 for automated approval through the GUS system. Scores below 640 aren't automatically disqualified, they route to manual underwriting, which is stricter but still possible with the right lender.
The 640 "magic number"
USDA the agency doesn't impose a hard credit minimum, and that's true across its full set of loan requirements. In practice, 640 is the threshold that matters, because it's the score most lenders require for an automated approval through USDA's Guaranteed Underwriting System (GUS). At 640 or above, the system can approve your file efficiently, with standard DTI flexibility.
Below 640: manual underwriting
If your score is 600 to 639, you're not out, but your file goes to manual underwriting instead of automated approval. Manual underwriting is more rigorous: it typically requires a lower DTI and closer scrutiny of compensating factors like cash reserves, stable employment, and a clean recent payment history. Not every lender offers manual underwriting on USDA, which is where a broker with access to lenders who do makes the difference between a yes and a no.
The DTI connection
USDA has some of the strictest DTI limits of any program: 29% housing / 41% total on manual underwriting, with more flexibility (34/46) through GUS. The higher your credit score, the more likely you clear GUS with its more forgiving ratios. A lower score pushing you into manual underwriting means you also face the tighter 29/41 caps, so credit and DTI are linked.
What to do if your score is borderline
If you're near 640, even a small improvement can move you from manual to automated underwriting, which eases the process significantly. Paying down revolving balances and making every payment on time are the fastest levers. If you're firmly below 640, the question becomes whether a lender will manually underwrite your file, or whether FHA (580 for 3.5% down) is the more realistic path.

Your file routes to manual underwriting, requiring a lower DTI (29/41) and stronger compensating factors. Not all lenders offer it.
