What Is a USDA Loan and Do You Qualify?
If you’re looking to buy a home with zero money down, a USDA loan might be the best-kept secret in the mortgage world. Many buyers assume it’s only for farmers or remote rural areas — but in reality, a large portion of properties across Arizona, including communities near Tucson and Sierra Vista, fall within USDA-eligible zones.
Here’s everything you need to know.
What Is a USDA Loan?
A USDA loan is a mortgage backed by the U.S. Department of Agriculture through its Rural Development program. The goal is to encourage homeownership in less densely populated areas by offering favorable terms — most notably, no down payment required.
The most common option is the USDA Guaranteed Loan, issued by approved private lenders like Altitude Home Loans and backed by the USDA. Because the government guarantees the loan, lenders can offer competitive rates even without a down payment.
USDA Loan Requirements: Do You Qualify?
To qualify, you need to meet four key requirements:
1. Property Location: The home must be in a USDA-eligible area. Despite the name, this doesn’t mean farmland — the USDA’s definition of “rural” includes many suburban communities and small towns. In Arizona, areas surrounding Tucson, Marana, Sahuarita, and Sierra Vista often qualify. A quick conversation with one of our loan officers can confirm eligibility for any specific address.
2. Household Income Limits: USDA loans are designed for low-to-moderate income buyers. Your household income — including all adults in the home — cannot exceed 115% of the area median income. Limits vary by county and household size and are updated annually. In Pima County, the limit for a family of four typically falls between $95,000 and $110,000.
3. Credit Score: The USDA doesn’t set a hard minimum, but most lenders look for a 640 or higher for streamlined approval. Scores below 640 may still qualify through manual underwriting.
4. Debt-to-Income Ratio (DTI): Lenders generally want a front-end DTI (housing costs) below 29% and a back-end DTI (all debts) below 41%, though exceptions exist with strong compensating factors.
USDA vs. FHA: A Quick Comparison
Both are popular government-backed options for first-time buyers, but they serve different situations:
| USDA Loan | FHA Loan | |
|---|---|---|
| Down Payment | 0% | 3.5% |
| Location Requirement | Eligible areas only | No restriction |
| Income Limit | Yes (115% of median) | No |
| Mortgage Insurance | ~0.35% annually | ~0.85% annually |
| Typical Credit Score | 640+ | 580+ |
If you’re buying in an eligible area and within income limits, a USDA loan will almost always cost less per month than an FHA loan. For buyers in urban areas that don’t qualify geographically, FHA is often the better path. See our full FHA vs. Conventional breakdown to compare further.
USDA Loan Fees
USDA loans have two fees to be aware of. The upfront guarantee fee is 1% of the loan amount and can be rolled into the loan — no out-of-pocket cost at closing. The annual fee is 0.35% of the remaining balance, paid monthly. Both are significantly lower than FHA mortgage insurance premiums.
Is a USDA Loan Right for You?
A USDA loan is worth exploring if you’re buying outside a major city, your household income falls within local limits, you want to avoid a large down payment, and the home will be your primary residence.
