USDA eligibility in Idaho: the income limits and the property map
Two gates decide a USDA loan in Idaho: your household income and where the home sits. Idaho happens to be one of the easiest states in the country to clear both. Every county runs at the national income floor, and almost everything outside the Boise, Coeur d'Alene, Idaho Falls, and Pocatello cores is on the eligible map. Here is how each gate works, from Ada County to the Payette County line.
USDA income limits in Idaho: how the household count works
USDA caps a loan at 115% of the area median income, and in Idaho that works out to the national floor in every single county. The standard limit is $122,800 for a household of one to four and $162,100 for five to eight, effective July 13, 2026. Here is the Idaho correction worth stating plainly: no county gets a high-cost bump. Ada County around Boise, fast-growing Canyon County around Nampa and Caldwell, and even the resort counties of Blaine and Teton all use the same $122,800 line.
The part buyers miss is who gets counted. USDA looks at every adult who will live in the home, not just the borrowers on the note, so a working adult child in a Meridian household or a partner you leave off the loan in Caldwell still counts toward the total. USDA also allows deductions for dependents and childcare that can pull an over-the-line Treasure Valley household back under $122,800. Idaho's median household income runs about $81,166 (Census, 2024), roughly $41,000 below the cap, so the large majority of Idaho families clear this gate before the deductions even come up.
| Household size | National standard limit (as of July 13, 2026) |
|---|---|
| 1-4 people | $122,800 |
| 5-8 people | $162,100 |
Look up your county on the USDA income eligibility tool, and in Idaho every county shows the same $122,800 floor. If a page tells you Boise or Sun Valley carries a higher USDA cap, it is wrong. When your income lands near the line, that is exactly when it pays to have someone run the deductions before you assume you are out.
USDA property eligibility in Idaho: reading the map
The home has to sit inside the USDA-eligible map, and in Idaho that rules out very little. The state is one of the most USDA-friendly in the country by geography. The only ineligible zones are the incorporated cores of Boise, Meridian, Nampa, and Caldwell in the Treasure Valley, plus the cores of Coeur d'Alene, Idaho Falls, and Pocatello. Everything past those seven footprints qualifies.
Around the Boise metro the eligible line runs right up to the edge of the built-up area. Middleton, Emmett, Homedale, Parma, Marsing, and New Plymouth are broadly eligible farm towns within commuting distance, and Weiser out west is the most affordable of the group at a $223,400 median home value (Census, 2024). Two exceptions matter: Star and Kuna have grown so fast, to about 14,745 and 27,158 people, that parts of them are trending off the map. Verify any Star or Kuna address before you count on it.
| Treasure Valley ring town | Population | Median household income | Median home value |
|---|---|---|---|
| Middleton (Canyon Co.) | 10,649 | $89,013 | $403,100 |
| Emmett (Gem Co.) | 8,275 | $58,750 | $342,000 |
| Weiser | 5,935 | $45,292 | $223,400 |
| Homedale (Owyhee Co.) | 3,069 | $62,117 | $238,000 |
| Parma (Canyon Co.) | 1,928 | $49,231 | $274,300 |
Population, income, and value figures are U.S. Census (2024). Every town is generally eligible; verify the exact address on the USDA map before relying on it.
Do not trust a ZIP code in the Treasure Valley. A single Ada or Canyon County ZIP can fall partly inside and partly outside the boundary, so two houses on the same Meridian-edge street can get different answers.

The third gate: occupancy and property type in Idaho
USDA is for owner-occupied primary residences only, whether that is a first home in Kuna or a move out to Emmett. You cannot use it for a rental, a vacation cabin near McCall, or an income property, and it is meant for buyers who do not already own a suitable home nearby. Eligible property types include existing homes, new construction, condos and PUDs, and new manufactured homes titled as real property. An existing manufactured home on an Owyhee County lot generally does not qualify unless it already carries a USDA loan.
The Idaho correction: no county gets a higher cap
A lot of USDA content misreads Idaho, and it costs buyers. The biggest error: some pages assume Boise, Sun Valley, or the resort counties carry higher income caps the way metro counties do elsewhere. They do not. Idaho holds the $122,800 floor (1-4 people) in all 44 counties, from Ada to Bonneville, with no high-cost exception anywhere. If a page shows the 1-4 limit as $119,850, it predates the July 13, 2026 increase (Procedure Notice 657); $112,450 is older still. If it quotes the guarantee fee as 2.75% or 3.5%, that is the statutory ceiling, not the 1.0% upfront and 0.35% annual charged since 2016. And if it says the Guaranteed loan has a maximum loan amount, it is confusing it with Section 502 Direct.
USDA eligibility questions
Does USDA count all household income or just the borrower's in Idaho?
USDA counts the income of every adult who will live in the home toward its Idaho eligibility limit, not only the people on the loan. A working adult child in a Nampa household or a partner you leave off the mortgage in Meridian still counts. The limit is 115% of the county median, which in Idaho is the $122,800 national floor for a household of one to four, so the whole household total is what decides it.
What is the USDA income limit in Idaho for 2026?
The 2026 USDA income limit in Idaho is $122,800 for a household of one to four and $162,100 for five to eight, effective July 13, 2026. Idaho uses that national floor in every county, so Ada County around Boise and the resort counties of Blaine and Teton get no high-cost bump. Because USDA raised the limit from $119,850, some Treasure Valley buyers turned away a year ago may qualify now.
How do I check if an Idaho address is USDA-eligible?
Enter the exact address into the USDA map at eligibility.sc.egov.usda.gov, or use the checker on this page. Checking by ZIP is unreliable in Ada and Canyon counties because a single ZIP can straddle the eligible boundary. Most addresses outside the Boise, Meridian, Nampa, Caldwell, Coeur d'Alene, Idaho Falls, and Pocatello cores qualify, but the fast-growing towns of Star and Kuna are the two to check carefully.
How much of Idaho qualifies for a USDA loan?
Almost all of it. Idaho is one of the most USDA-friendly states in the country, with only the urban cores of Boise, Meridian, Nampa, Caldwell, Coeur d'Alene, Idaho Falls, and Pocatello left off the map. Ring towns like Middleton, Emmett, Weiser, Homedale, and Parma are eligible, and combined with incomes under the $122,800 cap, most Idaho households can actually use USDA.
