The USDA Loan Master Guide (2026 Edition)

A USDA loan is a mortgage backed by the U.S. Department of Agriculture through its Rural Development program. In the main program, the USDA doesn't lend the money — private lenders do, and a USDA loan note guarantee (up to 90%) protects them against a large share of any loss. That backing unlocks 100% financing at competitive rates.

It exists to make homeownership accessible in rural and many suburban areas for low-to-moderate-income buyers. Two things decide who qualifies — and trip up most applicants: where the home is and how much your household earns (both covered in Section 4).

Two programs, one name

"USDA loan" usually means the Guaranteed program (Section 502 Guaranteed), issued by lenders for moderate-income buyers. A separate Direct program is run by the USDA itself for very-low-income buyers, where payment assistance can cut the effective rate to as low as 1% (Section 3). Either way, the home must be your primary residence — no investment or vacation properties, and you're generally expected to occupy it within 60 days of closing — though you don't have to be a first-time buyer.

The tracker above shows USDA's rate advantage in real time — the USDA line sits beneath the 30-year conventional benchmark.

USDA rates are consistently among the lowest of any program — often at or below comparable conventional rates — thanks to the government guarantee. As of mid-2026, 30-year USDA rates have generally sat in the low-6% range. Because rates vary by lender and profile, compare full Loan Estimates rather than headline rates.

Why USDA rates are low

The guarantee removes most of the lender's default risk, so lenders can price USDA loans aggressively. And USDA itself doesn't add credit-score pricing adjustments the way conventional loans do — though individual lenders may still vary their pricing by credit.

These are two different programs people constantly confuse — and applying to the wrong one wastes weeks.

This guide focuses on the Guaranteed program, which serves the broadest pool. If your household income is well below your area's median, ask a USDA Rural Development office whether Direct is a better fit.

USDA approval comes down to two gates. Clear both and you're in; miss either and you're out — no matter how strong your credit or income.

Gate 1: The property must be in an eligible area

• "Rural" is broader than it sounds. It covers most small towns and many outer suburbs — not just farmland. Plenty of buyers who'd qualify never check.
• The USDA eligibility map is the only authority. Enter the exact address before writing an offer. Population rules of thumb (you'll see both "20,000" and "35,000" cited) don't substitute for the map.
• The home must be a modest, owner-occupied primary residence. Existing homes, new builds, and some manufactured homes qualify — though manufactured homes carry extra rules (generally new and permanently affixed, meeting program standards; your lender confirms eligibility). Working farms and income-producing properties don't qualify.

Gate 2: Household income must be under the cap

The Guaranteed program caps income at 115% of area median income and counts income from every adult in the household — not just the borrowers.

These are standard-area figures — your county may be higher, and households larger than 8 add 8% of the 4-person limit per additional person. Check your county and allowable deductions on the USDA income-eligibility site.

Quick eligibility checklist

USDA files run through GUS — the Guaranteed Underwriting System, USDA's automated engine. Two ratios anchor the decision:

A GUS "Accept" recommendation can clear higher ratios automatically — no waiver needed. Manually underwritten purchase files must meet 34/41, with a possible waiver to 34/44 under USDA's compensating-factor test (strong reserves, validated 680+ score, low payment shock). The 34% housing cap itself can't be waived on a purchase.

• No USDA minimum credit score. Most lenders look for ~640 for automated GUS approval; below that, manual underwriting is possible but documentation-heavy. Overlays vary, so a decline from one lender isn't a decline from all.
• A roughly two-year history of stable income and employment is the norm.

USDA has no down payment and no monthly mortgage insurance. In their place are two modest fees that fund the program — together cheaper than FHA's mortgage insurance over the life of the loan.

Fees shown are the FY 2026 schedule (RD Instruction 440.1) and are reviewed annually.

Cost rules in your favor

• No down payment, no PMI.
• 6% seller concessions — sellers can contribute up to 6% of the price toward your closing costs (standard closing costs outside this cap are still allowed).
• Finance eligible closing costs — if the home appraises above the purchase price, USDA lets you roll certain closing costs into the loan, up to the appraised value (plus the financed upfront guarantee fee). Rare among programs — it's how USDA buyers can close with little to no cash.
• No prepayment penalty.

One catch: unlike conventional PMI, the 0.35% annual fee doesn't auto-cancel at 20% equity — it runs for the life of the loan. The only ways to drop it are to pay the loan off or refinance out of USDA.

A USDA purchase typically takes 30–45 days. The one difference from other programs: you confirm eligibility first, before you shop.

1. Check both gates. Confirm the address on the USDA eligibility map and check your household income against the cap.
2. Get pre-approved. A USDA-approved lender verifies income, credit, and debts and runs your file through GUS.
3. Go under contract. Stay within eligible areas; request seller concessions (up to 6%).
4. Appraisal. The home is appraised for value and must be safe, sanitary, and structurally sound; required repairs may need to be completed before closing.
5. Closing. Review the Closing Disclosure, sign, and move in as your primary residence.

Refinancing a USDA loan

Existing USDA borrowers can use the Streamlined-Assist refinance. The core requirements: an existing USDA loan, 12 months of on-time payments, and a new payment (PITI including the annual fee) that drops by at least $50/month. It typically requires no new appraisal, credit report, or DTI calculation — though individual lenders may verify more. Standard and non-streamlined USDA refinances are also available.

Assumable: USDA loans are generally assumable — a qualified buyer may be able to take over the loan and its rate, subject to lender and USDA approval.

When each wins

• USDA wins if you qualify — in an eligible area, under the income cap, with little cash to put down. It's typically the lowest all-in cost of the three.
• FHA wins when the home isn't in a USDA area or your income is over the cap — especially with lower credit (high-500s).
• Conventional wins with strong credit and 20%+ down: no mortgage insurance, no location or income limits, and it's the only option for investment properties.

What USDA can't do

• No ineligible locations. If the address isn't on the USDA map, there's no USDA loan — check before you fall for a house.
• No high earners. Over 115% of area median income (counting the whole household) and you're out.
• No investment or vacation homes. Primary residence only.
• No income-producing property. Working farms and homes with commercial operations don't qualify; the home must be modest.

Common pitfalls

• Self-disqualifying on income. Deductions for dependents, childcare, and elderly or disabled members often bring you under the cap — let a lender run the adjusted figure.
• Counting only the borrowers' income. USDA counts every adult in the household, even non-borrowers; a working adult child can push you over.
• Assuming "rural" means farmland. Many suburbs qualify — people who'd be eligible often never check the map.
• Treating 640 as a hard rule. It's a common lender overlay, not a USDA minimum; another lender may go lower.
• Forgetting the annual fee is for life. Unlike conventional PMI, it doesn't drop at 20% equity — refinancing out is the exit.

Does USDA require first-time buyer status?

No. The Guaranteed program is open to repeat buyers — you just have to occupy the new home as your primary residence.

Do I have to be a U.S. citizen?

U.S. citizens, U.S. non-citizen nationals, and qualified permanent residents generally qualify. Other lawful-resident categories may qualify depending on USDA and lender guidance.

Can I use gift funds?

Yes. You don't need a down payment, but gift funds can cover closing costs and other eligible expenses.

Do I need cash reserves?

There's no formal reserve requirement for most Guaranteed loans, though reserves can strengthen a borderline file.

Can I buy a duplex or multi-unit home?

No. Guaranteed-program purchases are for single-unit, owner-occupied primary residences.

How long does USDA approval take?

Typically 30–45 days, similar to other mortgage programs.
