How down payment assistance income limits work
The ceiling is almost never a single national number. It is set county by county, adjusted for household size — and it is usually higher than buyers assume.
Nearly every assistance programme has an income ceiling, because the funding is targeted at buyers who need it. What trips people up is the assumption that the ceiling is low. In many counties it sits comfortably above the local median household income, and it rises with the number of people in the household.
Area median income (AMI) — the unit almost everyone uses
Programs usually express their ceiling as a percentage of the area median income for the county or metropolitan area, published annually by HUD (HUD income limits datasets). You will see limits written as "80% AMI", "100% AMI", "140% AMI" and so on.
Two consequences follow, and both work in the buyer's favour more often than not:
- It is local. The ceiling in an expensive metro is far higher than in a rural county, because the median it is based on is higher.
- It scales with household size. Limits are published per household size, so a family of four faces a higher ceiling than a single buyer.
Which income actually counts
This is where programs diverge, and where an incorrect self-assessment usually comes from.
| Approach | What is counted | Effect |
|---|---|---|
| Qualifying income | Only the income of the people on the loan application, as underwritten. | More generous. A working adult in the household who is not on the loan may not count. |
| Household income | Income of all adults living in the home, whether or not they are borrowers. | Stricter. Common in programs funded from federal grant sources. |
Other details that change the answer: whether the figure is gross or net, whether overtime and bonuses are annualised, how self-employment income is averaged, and whether documented non-employment income counts. None of these are guessable — they are stated in each programme's guide.
Do not disqualify yourself on arithmetic you did in your head. The three most common self-elimination errors are: using a national figure instead of your county's, using the limit for a single-person household when you have a family, and counting a housemate's income against a programme that only counts borrowers.
Income limits are not the only cap
Programs typically stack several ceilings, and you must clear all of them:
- Income limit — the subject of this page.
- Purchase price limit — a maximum home price for the county, independent of your income.
- Loan limit — set by the loan type you are using, not by the assistance programme.
- Debt-to-income limit — the underwriting cap, roughly 31%/43% under FHA guidelines (FHA Single Family Housing Policy Handbook 4000.1 (HUD)).
The binding constraint differs by household. High earners with large debts are usually stopped by DTI, not by the income ceiling. Lower earners with no debt are usually stopped by the payment their income supports — which is exactly what the calculator on this site measures.

Being marginally over one programme's ceiling is not the end of the search. Practical options, in the order worth trying:
- Check other programs. City and county programs often set different ceilings from the state programme, and they stack differently.
- Check the household-size row again. Limits step up materially with each additional household member.
- Check targeted areas. Many agencies raise or remove income ceilings for purchases in designated areas.
- Check which income the programme counts. A qualifying-income programme may treat your situation differently from a household-income one.

Frequently asked questions
What income limit applies to down payment assistance?
There is no single national limit. Most programs set their ceiling as a percentage of the area median income for your county, published annually by HUD, adjusted for household size. Check your county and household size rather than a national figure.
Does my whole household’s income count?
It depends on the programme. Some count only the income of borrowers on the loan application; others count all adults living in the home. Programs funded from federal grant sources more often use the broader household test.
What if I earn slightly over the income limit?
Look at other programs — city, county and employer schemes set their own ceilings — and re-check the limit for your actual household size and for any targeted areas, where ceilings are often higher or waived.
