USDA Loan Requirements in 2026: The Real Checklist

The checklist I actually run before I tell someone yes

When a buyer calls and asks, "Do I qualify for a USDA loan?" I do not answer from a brochure. I walk through the same short list of boxes on every file, because those boxes are what the underwriter and USDA's automated system are going to check anyway. If you understand them before you start, you will not waste time falling in love with a house you cannot finance this way.

Here is the real 2026 checklist we use with clients, in plain language.

Box one: Is the property in an eligible area?

Everything starts with location. A USDA loan only works on a home inside a USDA-eligible rural area, and eligibility is decided at the address level, not the city level. Two houses on the same road can land on opposite sides of the line.

The good news for our markets is that most of the map is open. Only about 4.5% of Texas and roughly 3.9% of Arizona is outside the eligible zone, and the ineligible parts are mainly the urban cores of Dallas, Fort Worth, Austin, San Antonio, Houston, El Paso, Phoenix, Scottsdale, and Tucson. Growing exurbs like Weatherford, Waxahachie, Terrell, Bastrop, Casa Grande, and Prescott Valley have large eligible areas.

Because these boundaries get redrawn and some towns keep eligibility only through grandfathering with sunset dates, we never publish a static "these towns qualify" list and leave it at that. We check your exact address on the USDA property-eligibility map. Our walkthrough on how to check if your address qualifies shows you how to do it in about five minutes.

Box two: Is your household income under the limit?

USDA is an income-limited program. The cap is set at 115% of the area median income for your county, and it is based on total household income, not just the borrowers. That surprises people. If your adult roommate, your working teenager, or a parent living with you has income, it counts toward the household total even if they are not on the loan.

For 2025, the base limit in most Texas and Arizona counties is $119,850 for a household of one to four people and $158,250 for a household of five to eight. Higher-cost metros carry higher limits. The Phoenix-Mesa-Chandler area, for example, runs closer to $129,000 for the smaller household tier. These are 2025 figures and USDA updates them, so treat them as a starting point and let us verify your county.

There are also deductions that can pull your qualifying income down, which is why some families who assume they earn too much actually come in under the cap. We dig into that in our breakdown of USDA income limits.

Box three: Does your credit tell a workable story?

USDA itself sets no hard minimum credit score. Lenders and USDA's automated underwriting engine do lean on a number, though. In practice, a score of 640 or higher lets us run your file through the Guaranteed Underwriting System, known as GUS, and get an automated "Accept" that streamlines the whole process.

Below 640 is not the end of the road. It moves you into manual underwriting, where we document compensating factors like reserves, a clean recent payment history, or a low debt load. It is more paperwork and a higher bar, but I close manually underwritten USDA loans regularly. If you are sitting in the low 600s, we treat that as a starting line, not a stop sign. Our post on the USDA credit score question explains exactly what 640 does and does not mean.

Box four: Do your debt ratios leave room for the payment?

Underwriters look at two ratios. The housing ratio compares your proposed mortgage payment to your gross monthly income, and the total ratio compares all your monthly debts to that income. USDA's general guidance lands around 29% for housing and 41% for total debt, though GUS allows flexibility and waivers when you have strong compensating factors.

What this means in practice is that student loans, car payments, and credit card minimums matter. Before you shop, it is worth knowing where you stand. You can get a quick read with our USDA loan calculator, then we tighten it up together.

Box five: Will you live there?

USDA loans are for primary residences only. No investment properties, no second homes, no flips. You need to occupy the home as your main residence. For most first-time buyers this box checks itself, but it does rule out anyone hoping to rent the place out from day one.

Box six: Are you eligible to borrow at all?

A few baseline items round out the file. You need to be a U.S. citizen, a U.S. non-citizen national, or a qualified alien. You cannot be suspended or debarred from federal programs. And the home has to be a property USDA will finance, which includes most single-family homes and some manufactured homes that meet the age, foundation, and permanent-attachment rules.

What the checklist looks like in the real world

Picture a couple renting outside Fort Worth. One works full time, the other part time, and together they earn about $95,000. Their credit sits at 662, they have a car loan and a small student balance, and they want a house near Weatherford. They walk through my checklist like this: the Weatherford-area address is largely eligible, their income is comfortably under the base cap, their 662 scores clear the GUS threshold, their ratios have room once we account for the car and student loan, and they plan to live there. That file is a strong USDA candidate, and I can tell them so on the first call.

Your file will have its own wrinkles. Maybe your income is close to the line, or your score needs a few months of work, or the address is split between eligible and ineligible zones. That is exactly the kind of thing we sort out before you write an offer.

Your next step

Do not try to grade your own file from memory. The two moving pieces, area eligibility and household income, change often enough that a guess from six months ago can be wrong today. Send me the address and your household income picture and I will run it against the current maps and limits.

If you want the fastest path, take our eligibility quiz and I will personally walk your file through this checklist. You can also start with the bigger picture in our guides to USDA home loans in Texas and Arizona.
