You qualify for an AMI apartment when your household’s gross annual income falls at or below the area median income tier set for that specific unit, once your income is measured against a limit adjusted for household size. Most affordable units are set at 30%, 50%, 60%, or 80% of AMI, and the dollar cutoff for each tier is published by HUD for every metro area and rural county in the country.
The label “affordable” alone doesn’t tell you whether you qualify. Two apartments in the same building can carry different income ceilings, so the question is always which tier the unit is restricted to and what that tier translates to in dollars where you’re applying.
The Income Tiers That Decide Eligibility
HUD publishes three standard tiers, and the Low-Income Housing Tax Credit program adds finer gradations on top:
- Extremely low income, at 30% of AMI. This is the ceiling for the deepest subsidies, including most public housing admissions and the majority of newly issued Housing Choice Vouchers.
- Very low income, at 50% of AMI. The general eligibility cap for the Housing Choice Voucher program.
- Low income, at 80% of AMI. The upper boundary for most federal housing assistance, including public housing and the HOME program.1U.S. Department of Housing and Urban Development. Income Limits
LIHTC units, which make up the largest share of affordable rental housing in the country, can be designated at 20%, 30%, 40%, 50%, 60%, 70%, or 80% of AMI, depending on the qualifying test the property chose when it was built. A property must reserve at least 20% of units for households at 50% of AMI, or at least 40% of units at 60% of AMI, or use an average-income test where units range from 20% to 80% of AMI so long as the average doesn’t exceed 60%.2Office of the Law Revision Counsel. 26 USC 42 – Low-Income Housing Credit The 60% AMI unit is the most common LIHTC designation. Ask the property manager which tier the specific unit you want is designated at, because that number is what your income gets compared to.
One useful combination: LIHTC properties are required to accept Housing Choice Vouchers as payment, so if you hold a voucher you can apply it to a tax-credit unit.3U.S. Department of Housing and Urban Development. Housing Choice Voucher Tenants
What Counts as Your Household and Your Income
This is where applicants most often miscalculate. Your household includes every person who will live in the unit, related or not, and every adult member (18 and older) has their income counted toward the total.4HUD Exchange. Household Income Determination FAQ An adult child living with you, or an unrelated roommate on the lease, adds their earnings to yours. A household of two working adults can land over the income limit even when neither person on their own earns much.
Annual income covers wages, salaries, overtime, self-employment profits, Social Security payments, pensions, retirement account distributions, recurring gifts, and most other recurring income from any source. Assets can also bump your countable income upward. When a family’s net assets exceed $52,787 (the 2026 threshold) and the actual return on those assets can’t be documented, HUD imputes income using a passbook savings rate of 0.40%.5eCFR. 24 CFR 5.609 – Annual Income So $60,000 sitting in a low-interest account can be treated as $240 in additional income for eligibility purposes.
One nuance to keep in mind: the income used to test eligibility is gross annual income. Deductions for dependents, elderly or disabled family members, medical expenses, and childcare exist under HUD rules,6eCFR. 24 CFR 5.611 – Adjusted Income but those deductions apply to calculating rent in public housing and Section 8 units, not to deciding whether you’re under the eligibility ceiling.
Looking Up the Dollar Cutoff for Your Area
AMI limits vary dramatically by location. A four-person household at 80% of AMI might qualify with $60,000 in a rural county and $90,000 or more in a high-cost metro. Always look up the limit for the area where the apartment sits, not where you live now.
HUD’s Income Limits Documentation System lets you search by state and county. Results show the 30%, 50%, and 80% tier limits broken out by household size from one to eight people.1U.S. Department of Housing and Urban Development. Income Limits Select your state, then your county or metro area, and the system returns a summary table.
Timing note: the FY 2026 limits release has been delayed to May 1, 2026, so properties in early 2026 are likely still applying FY 2025 limits until the new figures take effect.7HUD USER. Statement on FY 2026 Median Family Income Estimates For the HOME program specifically, the extremely low-income calculation can differ slightly from the Section 8 figure for the same area,8HUD Exchange. HOME Income Limits so use the limit chart tied to the program funding the building.
Applying: Documents, Waiting Lists, and Screening
Finding the units takes legwork. Local housing authority websites, HUD’s resource locator, and state affordable housing search portals are the most reliable starting points. Property management companies that specialize in affordable housing also list vacancies directly. Voucher holders can ask the issuing housing authority for lists of participating landlords.
Documents to Gather Before You Apply
Income verification is the most document-heavy step. Expect to provide:
- At least one month of recent pay stubs with enough detail to calculate annual income. If a stub doesn’t show enough, the program may contact your employer directly.9U.S. Department of Housing and Urban Development. Policy Guidance 2024-07 – Income Verification
- Bank statements covering two months.
- Original benefit letters for Social Security, pension, or public assistance income.
- Tax returns and profit-and-loss statements if you’re self-employed.
- Documentation of child support, alimony, and any recurring financial contributions.
- Asset verification for bank accounts, investment accounts, retirement funds, and any real property.
Gathering these before you apply saves weeks of back-and-forth.
Lotteries, Waiting Lists, and Preferences
Demand far exceeds supply in most areas. Many properties use a lottery to decide which applications get reviewed first, and being selected in the lottery moves you to eligibility screening rather than guaranteeing an apartment. Properties that don’t use lotteries maintain waiting lists that can stretch months or years.
Priority often goes to applicants experiencing homelessness, those spending more than 50% of income on rent, or households displaced by a natural disaster or government action. Veterans and current residents of the jurisdiction may also receive preference. These vary by property, so read each listing’s preferences before assuming your place in line.
Background and Credit Checks
Most affordable housing programs run background checks before finalizing admission. Current HUD guidance directs housing authorities and owners of federally assisted housing to screen applicants for criminal history and to enforce rules on criminal activity and drug use. Credit screening varies by property, and poor credit alone doesn’t automatically disqualify you everywhere. If you’re denied, you’re entitled to written notice and, in most programs, an opportunity to dispute the decision or present mitigating circumstances.
After You Move In: Recertification and Over-Income Rules
Qualifying once doesn’t lock in your unit indefinitely. Most programs require annual income recertification, where you resubmit pay stubs, benefit letters, tax returns, and asset documentation. Miss the deadline and you can jeopardize your lease. Treat it like a second application each year.
What happens if your income rises depends on the program. In a LIHTC unit, you’re considered over-income only when your household income exceeds 140% of the applicable limit, and even then the unit keeps its low-income status as long as the property rents the next available comparable unit to an income-qualified household.2Office of the Law Revision Counsel. 26 USC 42 – Low-Income Housing Credit You won’t be evicted for earning more. In public housing, a higher income means higher rent, calculated as the highest of 30% of adjusted monthly income, 10% of gross monthly income, or a welfare rent where applicable.10Office of the Law Revision Counsel. 42 USC 1437a – Rental Payments
