FAQ
What DTI does USDA allow at 600?
GUS automated allows up to ~41% total; manual is stricter, often 29/41% targets with compensating factors.
Can I exceed income limits?
No, 115% of area median income is a hard cap for the household.
Is the USDA fee like PMI?
The 1% upfront + 0.35% annual guarantee fees function like MI but are cheaper than FHA’s, and the annual fee is score-blind.
