What is the USDA loan income limit in Idaho?

In most Idaho counties the USDA Guaranteed Loan moderate-income limit is $122,800 for a 1-4 person household and $162,100 for a 5-8 person household, from the FY 2026 USDA table effective 07/13/2026. Higher-cost metro counties can have higher limits, so confirm the exact county row in USDA's income-limit PDF.

What is the USDA Section 502 Direct loan income limit in Idaho?

The Direct loan uses lower income limits than the Guaranteed program on this page. Section 502 Direct is reserved for low-income (at or below 80% of area median income) and very-low-income (at or below 50% of AMI) Idaho households, versus the moderate-income 115%-of-AMI ceiling that produces the $122,800 / $162,100 Guaranteed figures. USDA funds the Direct loan itself and can add a payment-assistance subsidy. Look up the exact Idaho county Direct income limit on USDA's eligibility portal under "Single Family Housing Direct."

Which areas of Idaho are USDA eligible?

Beyond the Treasure Valley, most of Idaho — the Panhandle, the Magic Valley, and the eastern farm counties — is USDA-eligible. The largest urbanized cities — Boise, Meridian and Nampa — and their immediate suburbs are excluded from the USDA Section 502 Guaranteed Loan eligible-area map, while the surrounding smaller communities generally remain eligible. Always confirm a specific address, because boundaries can run mid-street.

Is the USDA income limit the most I can borrow in Idaho?

No. The income limit only screens whether your household is eligible for the program. The loan amount is set separately by a USDA-approved lender using repayment income and the 29% PITI / 41% total-debt ratio guidelines; USDA sets no maximum loan amount.

Do you need a down payment for a USDA loan in Idaho?

No. The USDA Section 502 Guaranteed Loan finances 100% of the appraised value with no down payment, making it one of the only true zero-down mortgages available to Idaho buyers who meet the eligible-area and income tests. A 1.00% upfront guarantee fee can be rolled into the loan and a 0.35% annual fee is spread across the monthly payment, so out-of-pocket cash at closing can be limited to a deposit and closing costs.

Is Caldwell and north edge USDA eligible?

Partly. On 2026-07-28, 1 of 4 points sampled inside Caldwell and north edge (Canyon County) fell outside USDA's published ineligible-area layer — so part of Caldwell and north edge reads as USDA-eligible area, but not all of it. Downtown plus the east and west sides returned inside the excluded area; the sampled point north of the city returned outside it. Because the line runs through the town itself, a ZIP or town name cannot answer this: run the exact street address.

Is Nampa USDA eligible?

No. Nampa itself is an excluded urbanized core: every point sampled inside the city on 2026-07-28 fell inside USDA's ineligible-area layer. The USDA-eligible ground near Nampa starts in the commuter belt — Caldwell and north edge, Star, Kuna, Middleton, Marsing, Emmett all returned at least partly outside the ineligible area on the same sample. Boundaries can run mid-street, so confirm the specific address.

Idaho income limit

In most Idaho counties the USDA Guaranteed Loan moderate-income limit is $122,800 for a 1-4 person household and $162,100 for a 5-8 person household (FY 2026 USDA table, PN 657, effective 07/13/2026).

Eligible areas in Idaho

Beyond the Treasure Valley, most of Idaho — the Panhandle, the Magic Valley, and the eastern farm counties — is USDA-eligible. The urbanized cores of Boise, Meridian and Nampa are excluded from the USDA map; their surrounding rural communities generally remain eligible.

USDA loan basics

Why buyers choose a USDA loan in Idaho

USDA generally defines an eligible rural area as one with a population of 35,000 or less, and for a home inside that map the Section 502 Guaranteed Loan finances 100% of the appraised value with no down payment — the two features that pull Idaho buyers toward USDA over FHA or conventional financing (USDA program facts verified 2026-06-26).

$0 down payment

The Section 502 Guaranteed Loan funds 100% of the appraised value, so qualified Idaho buyers bring no down payment. A 1.00% upfront guarantee fee is financeable and a 0.35% annual fee is built into the monthly payment.

Population 35,000 or less

An area qualifies as USDA “rural” when its population is 35,000 or less and it is rural in character — which is why most of Idaho outside Boise and the other large metros stays on the eligible-area map.

Income up to 115% of AMI

The program serves low- and moderate-income households — generally up to 115% of the area median income for the Idaho county, which is how USDA derives the $122,800 / $162,100 limits above.

Direct vs. Guaranteed

Section 502 Direct vs. Guaranteed loan income limits in Idaho

USDA runs two different Section 502 home-loan programs with two different income limits: the Guaranteed loan caps household income at 115% of the Idaho county area median income (the $122,800 / $162,100 figures on this page), while the Direct loan is far tighter — reserved for low-income (at or below 80% of AMI) and very-low-income (at or below 50% of AMI) households. This precheck and every income figure above cover the Guaranteed program; the Direct program uses its own, lower county limits (USDA program facts verified 2026-07-15).

Section 502 Guaranteed — up to 115% of AMI

A USDA-approved private lender funds the loan and USDA guarantees it. Moderate-income Idaho households up to 115% of the county AMI qualify, which is how USDA derives the $122,800 (1-4) / $162,100 (5-8) limits this page tracks. No down payment; a 1.00% upfront and 0.35% annual guarantee fee apply.

Section 502 Direct — very-low (≤50%) / low (≤80%) of AMI

USDA funds the loan directly and can add a payment-assistance subsidy that lowers the effective interest rate for the lowest-income Idaho buyers. Because the income ceiling is 50-80% of county AMI rather than 115%, the Direct income limits are lower than the figures on this page — look up the exact Idaho county Direct limit on USDA's eligibility portal (choose “Single Family Housing Direct”).

Eligible-area examples

Representative USDA-eligible-area communities in Idaho

In Idaho, small cities well under USDA's 35,000-person rural-area population ceiling and outside Boise, Meridian and Nampa generally sit inside the USDA Section 502 eligible-area map — Sandpoint, Blackfoot, Preston and Salmon are representative examples, each a rural Idaho city under 35,000 residents at the 2020 Census. USDA sets eligibility address by address, so confirm the exact street address in the precheck.

These name the kind of eligible-area community, not a determination for any single address: USDA boundaries can run mid-street even inside a generally eligible town, and the excluded metros — Boise, Meridian and Nampa — and their immediate suburbs stay off the map.

Boundary sample

Where the USDA line actually falls around Nampa

On 2026-07-28 we queried USDA's published ineligible-area map layer — the same layer the precheck on this site uses — at 24 separate points across the Nampa commuter belt. 15 of the 24 points fell outside USDA's ineligible area — but none of them were inside Nampa itself. The USDA-eligible ground starts in the surrounding towns, and in 2 of them the line runs through the town itself.

Community	County	Points outside the ineligible area
Nampa	Canyon County	0 of 5Last verified: 2026-07-28. Downtown plus the north, east, west and northeast sides all returned inside USDA's ineligible area — Nampa proper is off the eligible-area map.
Caldwell and north edge	Canyon County	1 of 4Downtown plus the east and west sides returned inside the excluded area; the sampled point north of the city returned outside it.
Kuna	Ada County	4 of 4The centre plus the east, west and south sides all returned outside USDA's ineligible area.
Star	Ada County	2 of 3The centre and west side returned outside the ineligible area; the eastern edge toward Eagle returned inside it.
Middleton	Canyon County	3 of 3The centre plus the east and west sides all returned outside the ineligible area.
Marsing	Owyhee County	2 of 2The centre and west side both returned outside the ineligible area.
Emmett	Gem County	3 of 3The centre plus the east and west sides all returned outside the ineligible area.

This is a dated reading of USDA's own layer (effective 2023-07-25) at a handful of points, not a determination for any address — which is exactly why the split counts matter. USDA and your lender make the final call, so enter the full street address in the precheck above.

Deep dive

A USDA Guaranteed Loan in Idaho turns on two separate USDA tests: whether the property sits in a USDA-eligible rural area, and whether household income is within the county income limit. Both must hold before a lender underwrites the file.

Idaho income limits by household size

USDA HB-1-3555 Appendix 5 sets the moderate-income limit per county and household-size band. Across most Idaho counties the floor is $122,800 (1-4 people) and $162,100 (5-8 people). For households above eight, USDA adds 8% of the four-person limit per additional person. The figure is adjusted annual household income after USDA's allowable deductions, not gross pay.

Where Idaho limits can be higher

Higher-cost metro counties can exceed the $122,800 / $162,100 floor. This precheck applies the national floor when a specific Idaho county row has not been ingested and labels it as a fallback, so confirm the exact county or metro row in USDA's official income-limit PDF.

Checking an Idaho address

USDA eligibility is address-level, not ZIP-level: one ZIP can straddle eligible and ineligible ground, and boundaries often run mid-street near Boise and other urbanized edges. Enter a complete Idaho street address in the live precheck to geocode the point and test it against USDA Rural Development's ineligible-area layer.

After the precheck

Save the Idaho address, county, household size, income, and check date. A USDA-approved lender and the Idaho USDA Rural Development state office confirm the official county row and final eligibility. Income eligibility is not a loan amount — the lender sets that with the 29% PITI / 41% total-debt ratios.

Is a specific Idaho town or suburb USDA eligible?: USDA eligibility is decided address by address, but as a rule the small Idaho cities well under USDA's 35,000-person rural-area population ceiling and outside Boise, Meridian and Nampa sit inside the USDA Section 502 eligible-area map — Sandpoint, Blackfoot, Preston and Salmon are representative examples (each is a rural Idaho city under 35,000 residents at the 2020 Census). A ZIP or town name is only a starting point because boundaries can run mid-street, so enter the exact street address in the precheck to confirm.
