Somebody told you to look into affordable housing. A friend, maybe. A case manager. An adult child doing research at the kitchen table. It sounded like a plan. Then you started reading, and the words stopped meaning anything. Area median income. 30 percent. Tax credit. Project-based. Waitlist. Here is the part almost nobody explains at the start. Affordable Housing, the kind that gets built and regulated and applied for, has two income limits. Not one. There is a most you can earn. There is also, in practice, a least you have to prove. Nobody publishes the distance between them. Most people find it by getting turned down.
This piece answers three questions: what you qualify for, why you might still be rejected, and what to do about it.
Two different things go by the same name
When people say housing is affordable, with a small a, they mean it costs an amount you can pay. That describes your situation.
Affordable Housing with capital letters is a category. A home whose rent is held down by a rule, in exchange for public money that helped build it or that pays part of the rent every month. The rules decide who is allowed to live there.
A home can be Affordable Housing and still not be affordable to you. That is not a mistake in the system. It is how the system works.
The ceiling: the most you can earn
Every spring, HUD publishes an income limit for your area. There are 2,644 of these areas in the country, and one of them covers your county.
The limit comes in bands, written as 30 percent, 50 percent, 60 percent and 80 percent. Those are shares of the median income where you live, adjusted for how many people are in your household. In round numbers, if the median for a one-person household in your area were $90,000, the 30 percent band would be about $27,000, the 50 percent band about $45,000, the 60 percent band about $54,000 and the 80 percent band about $72,000.
Here is a real one. For the Portland, Oregon area in 2026, the published limits for a one-person household are $26,970 at the 30 percent band, $44,950 at 50 percent, $53,940 at 60 percent and $71,920 at 80 percent.
Do not do the percentage yourself. HUD adjusts these numbers, so use the published figure for your county. Our locator will show it to you.
Two things to know about the bands. The lower the number, the cheaper the rent and the scarcer the housing. And these are maximums: earn more, you are out.
Where the rent comes from
This is the piece almost nobody explains, and it turns out to be the hinge of the whole thing.
The rent in most Affordable Housing is not based on what the building costs to run. And it is not based on what you earn. It is worked out by a formula.
HUD publishes the income limits. Your state housing agency takes those limits and calculates a maximum rent for every apartment size at every band. The rent is set at 30 percent of that band's income limit for a household of that size, spread over 12 months. The 30 percent never changes. What the bands change is which income limit the 30 percent is taken from. That produces a published table of maximum rents for your county, and the building may charge up to that number. In Oregon, Oregon Housing and Community Services publishes both tables together.
So the rent is a set amount, tied to what people in your area earn. Not to what you earn. And that is exactly where the trouble starts.
The floor: what the property makes you prove
Because the rent is a fixed amount rather than a share of your income, the building has to satisfy itself that you can pay it every month. So it does what landlords everywhere do. It asks you to prove you earn some multiple of the rent.
This is not a federal rule. No federal rule for these programs sets a minimum income for anyone. It is a screening practice, and each property picks its own number, which means two buildings on the same street can pick differently. But the effect is a floor, and it is as real as the ceiling.
Here is the math. If the rent is $500 a month and the property wants three times the rent, you need to document $1,500 a month coming in. That is $18,000 a year, and it has to be provable: Social Security, a pension, a part-time job, all added together.
Now use a real rent. In Portland, a one-bedroom at the 60 percent band rents for up to $1,444 a month. Three times that is $4,332 a month, or $51,984 a year. Set that against the ceiling for the same person in the same building:
- The most you may earn: $53,940 a year.
- The least you must prove: $51,984 a year.
A window of $1,956 a year. About $163 a month. Earn less and the property turns you down. Earn more and the rules turn you down.
We measured that window in all 2,644 areas. The typical one is narrower than Portland's: about $1,370 a year, which is roughly $114 a month. In 96 out of every 100 areas it is under $2,000 a year.
The same thing, in dollars
Here is the whole problem as a table, which is easier to hold onto than a percentage.
The first column is the monthly rent. The next three show what a building would ask you to prove you earn each month, at each of the three common multiples. The last two columns are roughly the most you may earn and still qualify, at the 60 percent band, for one person, by the month and by the year.
| Monthly rent | Prove 2x | Prove 2.5x | Prove 3x | Most you may earn, a month | Most you may earn, a year |
|---|---|---|---|---|---|
| $500 | $1,000 | $1,250 | $1,500 | about $1,556 | about $18,700 |
| $750 | $1,500 | $1,875 | $2,250 | about $2,333 | about $28,000 |
| $1,000 | $2,000 | $2,500 | $3,000 | about $3,111 | about $37,300 |
| $1,250 | $2,500 | $3,125 | $3,750 | about $3,889 | about $46,700 |
| $1,500 | $3,000 | $3,750 | $4,500 | about $4,667 | about $56,000 |
Look at the 3x column against the one beside it. At a $1,000 rent, you must prove $3,000 a month coming in, and you may not earn more than about $3,111. That is a window of $111 a month. Not a year. A month.
The annual column is there for a reason. $4,667 a month reads like a comfortable income. $56,000 a year reads like what it is, and it is the most a single person may earn and still qualify for a $1,500 apartment.
For scale: the cheapest 60 percent one-bedroom in the country rents at $315, and the national median is $1,012. So the $1,000 row is the closest thing to a typical American apartment.
The last two columns are calculated from the same formula that sets the rent, and it lands within a fraction of a percent of Portland's published figure, so the arithmetic is sound. It is still an approximation and it varies by area. Our locator gives the exact numbers for your county.
Almost nowhere limits how high the multiple can go. Two places do. Portland, Oregon caps it at two and a half times the rent. Colorado caps it at two times, statewide. That single number matters more than anything else here. For an older adult on the average Social Security benefit, a three times requirement leaves her qualifying somewhere in about 8 out of every 100 areas in the country. A two times requirement leaves her qualifying in 96 out of 100. Nothing about her changed. Only the multiple did.
So here are the two questions to ask
Before you fill in anything, before you gather a single document, call the building and ask these.
Ask every building, before you apply:
- Is the rent based on my income, or is it a set amount?
- Do any apartments here come with rental assistance?
If the answer to either is yes, everything in this article about floors and multiples stops applying to you. Get on that list.
And if the rent is a set amount, ask the follow-up: what income do I need to document, and is it a multiple of the rent? Property staff answer that all day. Nobody thinks it is rude.
Five minutes on the phone is the highest-return thing available to you in this whole process. It is worth more than any application you will fill out this month.
What this looks like for one real person
The average Social Security retirement benefit in 2026 is $2,071 a month, or $24,852 a year. Take one person at exactly that income, looking for a one-bedroom, and run her against every area in the country.
For the deepest 30 percent homes, she earns too much in 93 out of 100 areas. That surprises people. It is not a screening problem, it is the published limit. The average retirement benefit has risen past the deepest affordability band in most of the country.
At the 60 percent band, she is comfortably under the ceiling almost everywhere and cannot prove three times the rent in 99 out of 100 areas.
Too well off for the cheapest homes. Too poor for the rest.
And one finding that comes up with every couple, and with everyone hoping to keep a room for a grandchild. In a two-bedroom at three times rent, the least you must prove is higher than the most you may earn in every single area in the country. All 2,644 of them. There is no place where that application works on income.
Are all the apartments in one building at the same level?
Not necessarily, and this is worth knowing when you are calling around.
Under the tax rules by themselves, a building people call a 60 percent building has one line: every tax credit apartment shares the same limit. But two things can put deeper apartments inside it.
Since 2018, a building may designate individual apartments at 20, 30, 40, 50, 60, 70 or 80 percent, in steps of 10, as long as the average lands at 60 or below. And separately, most buildings take money from more than one place, and the extra funders attach their own conditions, which is often what creates the 30 percent apartments. The rent follows the designation: a 30 percent apartment's rent cap is exactly half a 60 percent apartment's, for the same number of bedrooms.
So do not assume the building's headline number applies to every apartment. Ask whether any are set below 60 percent.
The kind of housing where none of this happens
Everything above describes housing where the rent is set by a table. There is another kind, where the rent moves with your income instead. There is no fixed rent, so there is nothing for a multiple to test. You cannot be too poor for it.
Your share is roughly 30 percent of your adjusted income and a subsidy covers the rest. Four things work this way:
- Public housing, owned by your local housing authority.
- Section 202, built since 1959 specifically for older adults with low incomes.
- Project-based rental assistance, attached to a particular building.
- A Housing Choice Voucher, sometimes still called Section 8, attached to you and usable in a private rental that accepts it.
This is the housing actually built for someone in your situation. It is also the housing there is the least of. Rental assistance reaches about one in four households eligible for it. Waiting lists for Section 202 commonly run two to seven years or more, and Congress has not funded any new Section 202 construction since 2024.
Apply anyway, and apply to several. The list is the only thing that improves while you wait.
Why the system works this way
Briefly, because it explains the floor and it is not anybody's bad behavior.
Most affordable housing built since 1986 has come through a federal tax credit. The credit pays to build. It does not pay to operate. With nothing covering the cost of running the building, rent cannot follow each resident's income. It has to be a set amount on a table. And a set rent has to be tested against something. That is where the floor came from. Nobody wrote it.
The same fact explains why new buildings are set at 60 percent rather than 30: a rent at the 30 percent band usually will not cover operating costs without an ongoing subsidy, and that subsidy is scarce. So the cheapest homes are the rarest, and the band that does get built is the one with the highest income requirement at the door.
If you want the longer version, we wrote it for housing professionals in Build, Preserve, Convert. And Activate.
Questions people ask us
These are general explanations, not financial or legal advice. Every program and every property applies its own rules. Confirm anything that matters to your decision with the property or with a benefits counselor.
Does Social Security count as income? Yes. A fixed benefit is documented income, which is exactly the difficulty. It counts, and it is small. There is no version of this where your benefit is discounted for being a benefit.
Do savings or a house count? Assets can be counted, usually by treating them as if they produced an income rather than counting the balance. If you are thinking about selling a home, ask about this specifically before you list it. More on that in If You Sell, Where Are You Going?
If I am over the ceiling for a 30 percent home, am I over it everywhere? No. The bands are separate ceilings. Being over the 30 percent limit tells you nothing about the 50 or 60 percent limits, and in most of the country you will be well under those.
Where do I find the actual rent and income tables? Income limits come from HUD at huduser.gov. Maximum rents come from your state housing agency, not from HUD. In Oregon, Oregon Housing and Community Services publishes both together. Note that the published maximum includes a utility allowance, so what a property may actually collect is a bit lower.
The thing to remember about the name
Affordable Housing is a legal category, not a promise about your budget. The rent in a 60 percent apartment is set from an income figure for your area. If your income is well below that figure, the rent was never calculated with you in mind.
So it is worth knowing what your own numbers look like before you organize your life around a waiting list. That is what The Value of a Match is for. It works out, in dollars, what a household in your situation is spending, what it has, and what changes if another person moves in.
Where home sharing sits in this
We run a home sharing platform. Read this section knowing that. We would rather be straight about the trade than sell past it.
Home sharing is a different kind of housing, not a cheaper version of the same one. An arrangement between two people has neither of the two gates in this article. No published income limit to exceed and no multiple to document. Nobody is turned away for earning too much or for earning too little. It is available now rather than after a wait that commonly runs two to seven years. And it works in both directions: the person opening a spare room gets income that may be what keeps them in a home they already own, and the person moving in gets a place they can afford.
What it does not carry is the rest of what regulation provides. No rent held down by a published table, no 30-year restriction keeping it there, and no guarantee of the independence, accessibility or security of tenure a subsidized apartment is built to offer. Those are real things to want, and for many people they are the right answer.
So this is not a contest, and we are not asking anyone to pick a side. Get on the lists. Ask about vouchers. Ask every property what multiple it uses and whether any apartments are set deeper. And while you are waiting, know there is a kind of housing with no income window at all, which you can arrange with a person you have chosen, in the community you already live in.
The one thing we would ask you not to do is spend a year applying to buildings that were never going to say yes, because nobody told you there were two limits.
