Low-Income Housing Tax Credit (LIHTC) Apartments: How Income Limits and Waitlists Differ by State

If you’ve ever seen an apartment complex advertise “income-restricted” units with rents that seem suspiciously reasonable for the neighborhood, you’ve probably encountered a Low-Income Housing Tax Credit property, usually just called LIHTC housing. It’s not a voucher, it’s not public housing, and it’s not run by your local housing authority — but it’s likely the single biggest source of affordable apartments in whatever state you’re moving to or from. Because the program is run through states rather than one national office, the details shift depending on where you live, and that trips up a lot of people who assume housing programs work the same everywhere.

What LIHTC housing is and how it differs from public housing or Section 8 vouchers

LIHTC apartments are privately owned and managed, but the owner got a tax credit from the state in exchange for agreeing to rent a portion of units to lower-income households at a restricted rent for a set number of years. There’s no government agency sending you a check or handing you a voucher. Instead, the “subsidy” happens on the building’s side — the developer gets the tax benefit, and you get access to a unit at a capped rent.

That’s different from public housing, where a housing authority owns and operates the building, and different from a Section 8 voucher, which follows you and can be used at almost any landlord who accepts it. With LIHTC, the affordability is tied to the specific unit and the specific building, not to you personally. If you move, you don’t take anything with you — you’d have to find another LIHTC property and apply fresh.

This also means LIHTC properties can look and feel like ordinary market-rate apartment complexes, sometimes mixed in with units that aren’t income-restricted at all. The property manager, not a caseworker, handles your application, your file, and your annual recertification.

How area median income (AMI) percentages set eligibility and why the same income limit looks different in different states

Eligibility for LIHTC units is based on a percentage of the Area Median Income, or AMI, for the county or metro area where the property sits — not a flat national income line. Most properties set limits somewhere in the range of 50% to 60% of AMI, though some buildings mix in units at 30% or 80% depending on how the developer structured the deal.

The catch is that AMI itself varies enormously by location, and it’s recalculated for each area every year. A household earning a given income might be well under the limit in a county with a high median income, and over the limit in a lower-income rural county in a different state — even if the dollar figure is identical. This is the single most common point of confusion for people who relocate: a cousin in one state tells them “I qualified making this much,” and they assume the same number applies where they’re headed. It usually doesn’t, because the local AMI is different and the household size matters too.

If you’re comparing options across states, don’t compare income limits by memory. Ask each property (or look up the published limits for that specific county) rather than assuming a number carries over.

Why rent at a LIHTC unit isn’t always as low as people expect, and how that varies by state and county

LIHTC rents are capped based on a formula tied to AMI, not based on what a tenant can actually afford. A unit set at the 60% AMI rent cap in a high-cost metro area can still be a stretch for someone with a low income, because the cap is calculated off the area’s median, not the tenant’s actual earnings. In a county with a high median income, “60% of AMI rent” can end up close to, or even above, what a modest market-rate unit nearby would cost.

This is why LIHTC housing works very differently depending on where you are. In a lower-cost rural county, the capped rent might genuinely be a bargain. In a pricier coastal or metro county, it can still be tight for a household at the bottom of the eligible income range. Some properties layer in deeper subsidies — a handful of units reserved at lower AMI percentages, or paired with a voucher — which brings the rent down further, but that’s not guaranteed at every building. It’s worth asking directly what the actual rent is for a unit at your household size and income tier, rather than assuming “affordable housing” automatically means “cheap.”

How states allocate tax credits differently, affecting how many units get built and where

Each state gets an annual pool of tax credits from the federal government, but every state’s housing finance agency decides, through its own written plan, how to score and prioritize developer applications for those credits. That plan might favor family housing in one state, senior housing in another, rural development in a third, or projects near transit in a fourth. States also decide how much of their credit pool goes toward brand-new construction versus rehabbing older buildings.

The practical effect is that LIHTC housing isn’t evenly spread. Some states and regions have built up a large stock of units over decades; others have comparatively little, especially in areas where the state’s allocation plan hasn’t prioritized that type of development or that part of the state. If you’re relocating and assuming affordable housing will be just as available in your new city as it was in your old one, that assumption can be wrong in either direction — there might be more options, or far fewer, depending entirely on how that state has chosen to direct its credits over the years.

Waitlist practices: lottery systems vs. first-come lists and how long they typically run

How you get on the list — and how long you wait once you’re on it — also depends heavily on the property and the state. Some LIHTC developments use a lottery, especially newer buildings that opened applications for a limited window and then drew names randomly from everyone who applied in that period. Others run an old-fashioned first-come, first-served waitlist that stays open indefinitely, where you add your name and wait your turn as units turn over.

Wait times can range from a few months to several years, and there’s no reliable way to predict it from state to state, since it depends on how much turnover a specific building has, how big it is, and how much demand exists locally. A property in a smaller city with several similar developments might move faster than a single well-known building in a tight rental market. It’s common for people to get mixed signals from friends or relatives who waited six months in one state and assume the same will happen elsewhere — when in reality the other property might be a multi-year list.

Ask the property directly whether the list is currently open, how it’s managed, and roughly how often units become available. Some properties will give you an honest estimate; others may not know until they actually have an opening.

How to find LIHTC properties in your state and what documents are needed to apply

Each state’s housing finance agency typically keeps a list, directory, or searchable map of LIHTC properties within its borders, since that agency is the one that approved the tax credits in the first place. That’s usually the most reliable starting point if you’re researching a state you haven’t lived in before, rather than relying on general apartment-search sites, which don’t always flag income restrictions clearly.

When you do apply, expect to provide proof of income for everyone in the household (pay stubs, benefit award letters, or tax documents), identification for all household members, and information about your current address and rental history. Some properties also ask about assets, since certain income limits factor in what you own as well as what you earn. Requirements vary by property, so it’s worth asking for a checklist before you show up with paperwork.

Key questions to ask a property manager before assuming you qualify

Before you get attached to a specific building, a short conversation with the property manager can save you a lot of guesswork. Worth asking: what AMI percentage applies to the units available, what that translates to in actual income limits for your household size, what the monthly rent is at that tier, whether the waitlist is currently open and how it’s structured, and roughly how long people have been waiting. It also helps to ask whether the income limits or available unit types have changed recently, since AMI figures get updated annually and can shift what you qualify for from one year to the next.

None of this guarantees a spot, and no property manager can promise you’ll be approved — but asking these questions up front means you’re comparing real numbers for that specific building and county, instead of carrying over assumptions from somewhere else.
