USDA vs Conventional in Tennessee (2026): Which Fits Your Down Payment and Location

When a buyer asks me whether to go USDA or conventional, I start with two questions before anything else: where is the home, and what does the household earn? Those two facts decide most of it. USDA's Single Family Housing Guaranteed Loan Program was built to help moderate-income buyers purchase in rural areas, so it attaches two gates a conventional loan doesn't have — a property-location requirement and a household-income cap.

A conventional loan is the standard loan sold to Fannie Mae or Freddie Mac. For a standard conforming loan, there's no geographic restriction and no income ceiling, which is exactly why it's the workhorse loan in Tennessee's metro cores. The trade-off: conventional almost always asks for a down payment, where USDA can be structured with none.

Neither one is automatically the right loan for every buyer — they solve different problems. A buyer purchasing outside the Nashville, Knoxville, Memphis, or Chattanooga cores who fits the income limit may find USDA's zero-down structure keeps the most cash in their pocket at closing. A buyer inside those metros, earning above the cap, or wanting a second home or a rental will need conventional. The honest answer is usually 'let's check the address and run the income,' not a blanket rule.

• Lean USDA when: the home sits in a USDA-eligible rural Tennessee area, it's your primary residence, household income is at or under 115% of the area median, and you want to put little or nothing down.
• Lean conventional when: the home is in a metro core or your income is above the cap, you want a second home or investment property, or you have a down payment ready and want to drop mortgage insurance later.

USDA's signature feature is 100% financing — no down payment on an eligible purchase. In exchange, USDA charges a 1% upfront guarantee fee, which can be financed into the loan, plus an annual fee of 0.35% of the remaining balance billed monthly. The part borrowers miss: that annual fee stays for the life of the loan. It does not fall off at a set equity point the way conventional mortgage insurance does.

Conventional needs a down payment — as little as 3% on Fannie Mae's 97% LTV options for eligible buyers, and commonly 5% otherwise. Put down less than 20% and you'll carry private mortgage insurance (PMI), but PMI isn't permanent. Under the federal Homeowners Protection Act, you can request cancellation in writing once your balance is scheduled to reach 80% of the home's original value, and your servicer must automatically terminate it at 78% as long as you're current.

So the real comparison isn't just 'who needs a down payment.' It's a longer-term cost question: USDA trades a smaller upfront cost for a fee that runs the life of the loan, while conventional asks for more cash now but lets you shed mortgage insurance as you build equity. Which one costs less over time depends on your down payment, how long you keep the loan, and how quickly you build equity. Your rate on either program depends on your credit profile and the market — there's no single number that fits every borrower.

• USDA: 0% down possible; 1% upfront guarantee fee (financeable); 0.35% annual fee that lasts the life of the loan.
• Conventional: as little as 3% down for eligible buyers; PMI required under 20% down; PMI requestable off at 80% LTV, auto-terminated at 78%.

This is the question I get most, and the answer surprises people: USDA eligibility is tied to the address, not the county name. The only reliable way to confirm it is the USDA property-eligibility map. Plenty of areas that don't feel 'rural' still qualify — USDA's definition reaches well beyond farmland into smaller towns and the outer edges of metro areas.

In practice, large portions of Middle and East Tennessee outside the dense cores of Davidson, Knox, Hamilton, and Shelby counties are eligible, and much of rural West Tennessee is too. Towns and unincorporated areas ringing the Nashville, Knoxville, Memphis, and Chattanooga metros frequently fall inside the eligible zones, while the cores of those four cities generally do not.

Boundaries can shift when USDA updates its maps after new census data, so an address that qualified a few years ago should still be re-checked at offer time. I've seen a home a few miles outside Clarksville, Murfreesboro, Cookeville, or Johnson City qualify while one closer to downtown does not — so I check the specific parcel every time, before a buyer commits to a property.

• Check the exact address on USDA's property-eligibility map — eligibility is parcel-specific, not county-wide.
• Metro cores of Nashville (Davidson), Knoxville (Knox), Chattanooga (Hamilton), and Memphis (Shelby) are generally not eligible.
• Smaller towns and the outer rings of those metros, plus much of rural Middle, East, and West TN, are commonly eligible.
• USDA also applies a household-income cap (115% of area median income) that varies by county and household size — both gates have to clear, not just one.

USDA financing is for owner-occupied primary residences only. You can't use it for a vacation home, a rental, or a property you don't intend to live in. The home also has to meet USDA's condition standards — similar in spirit to other government-backed programs, the property must be safe, sound, and sanitary, and the appraisal will flag issues that need to clear before closing.

Conventional is far more flexible on occupancy. The same conventional framework can finance a primary residence, a second home, or an investment property, with the down payment and pricing adjusting for each. That flexibility, plus the absence of income and location gates, is why conventional dominates among repeat buyers and anyone purchasing in Tennessee's larger cities.

If you're an active-duty servicemember or veteran near Fort Campbell or in the Clarksville area, it's worth putting a VA loan next to USDA on paper — VA offers its own no-down-payment path without USDA's rural and income limits. For any individual buyer, the right call comes from comparing the actual programs side by side, not from assuming one wins.

• USDA: primary residence only — no second homes or investment properties.
• Conventional: primary residence, second home, or investment property all allowed.
• Both require the property to meet program condition and appraisal standards.
• Eligible military buyers near Fort Campbell or Clarksville should also compare a VA loan before deciding.

Tennessee buyers can sometimes layer state assistance on top of either loan. The Tennessee Housing Development Agency (THDA) runs the Great Choice and Homeownership for the Brave programs, which can provide down payment and closing-cost assistance for eligible buyers who meet THDA's income and purchase-price limits.

Where the assistance goes depends on the loan. Because conventional generally requires a down payment, THDA help is especially useful for covering that 3% to 5% on a conventional purchase. With USDA's zero-down structure there's no down payment to cover, so assistance is more often directed at closing costs instead.

THDA programs carry their own income limits, purchase-price caps, and a homebuyer-education requirement, and they are not a guaranteed approval — you still qualify on credit and debt-to-income. The combination that actually works for you depends on your numbers, so it's worth mapping the down payment, the fee structure, and any assistance before you start shopping rather than after you're under contract.

• THDA programs can pair with conventional or USDA loans for eligible Tennessee buyers.
• On conventional, assistance often funds the down payment; on USDA, it more often offsets closing costs.
• THDA has its own income and purchase-price limits, plus a homebuyer-education requirement.
