Tucson down payment assistance programs set income limits in different ways. Arizona's HOME Plus caps the borrowers' income at $155,386 statewide for 2026. The Pima Tucson Homebuyer's Solution measures applicant income against one cap for every household size: $155,386 with FHA, VA, USDA-RD or Fannie Mae HFA Preferred loans, or $79,840 with its 80%-of-AMI conventional options. Pima Tucson Lighthouse, when a funding round is open, sets household income limits that vary by household size. Each program revises its limits periodically.

Tucson Down Payment Assistance: Income Limits Explained

Lighthouse availability: Pima Tucson Lighthouse is released in limited funding rounds that close once the money is committed. When we checked the Pima Tucson Housing Innovation Hub in October 2026, it listed the latest round as closed. Lighthouse details in this article describe how the program works when a round is open, and each round's lender guidelines set its eligible loan types. Ask us whether a round is open before you plan around it; the Pima Tucson Homebuyer's Solution and Home Plus Arizona remain available in the meantime.

One of the first questions we get from Tucson buyers is: "Do I make too much money to qualify for down payment assistance?"

It's a fair question. Most DPA programs have income limits, and understanding how they work can save you time and frustration.

Let's break it down clearly.

Why Do DPA Programs Have Income Limits?

Down payment assistance programs exist to help people who need them. The goal is to make homeownership accessible to moderate-income households who might otherwise struggle to save a down payment.

Income limits ensure that the limited funds available go to buyers who benefit most from the help.

How Income Limits Are Set

Many DPA income limits are based on the Area Median Income (AMI) for your county. For Pima County (which includes Tucson), HUD publishes updated AMI figures each year.

Programs that use AMI set the limit at a percentage of it. In Pima County, City of Tucson / Pima County HOME assistance is generally limited to 80% of AMI, and the Homebuyer's Solution's lower $79,840 cap applies to its 80%-of-AMI conventional options. HOME Plus doesn't use an AMI percentage at all.

The specific percentage depends on the program and loan type.

What Counts as "Income"?

This trips up a lot of people, because programs count income differently. Some measure gross household income; HOME Plus counts only the borrowers on the loan, and the Homebuyer's Solution counts applicant income as the loan agency calculates it. The kinds of income that can count include:

• Base salary or hourly wages
• Overtime (if consistent)
• Bonuses and commissions
• Self-employment income
• Rental income from investment properties
• Social Security or disability income
• Pension or retirement income
• Child support and alimony (in some cases)

Under a household-income program, such as a Lighthouse round, income from all adults living in the home can count, not just the borrowers. Under HOME Plus, only the borrowers' income counts.

Example:

Say your spouse works but won't be on the mortgage. A household-income program adds both paychecks together; HOME Plus looks only at the income of the borrower on the loan. That's why the same couple can be over one program's limit and under another's.

Income Limits by Program

Here's a general overview of how income limits work for the main DPA programs available in Tucson:

Pima Tucson Homebuyer's Solution

The Homebuyer's Solution measures applicant income, calculated under the loan agency's guidelines, against one cap for every household size: $155,386 with FHA, VA, USDA-RD or Fannie Mae HFA Preferred loans, and $79,840 with Fannie Mae HFA Preferred or Freddie Mac HFA Advantage loans for incomes at or below 80% of AMI (limits revised June 2026). Adding household members doesn't change either cap.

Pima Tucson Lighthouse Program

When a funding round is open, Lighthouse publishes household income limits for that round, and its program page says they vary by household size, so a larger household can have a higher limit.

Home Plus Arizona

Home Plus works differently. Arizona IDA sets one income cap for every county and household size, $155,386 for 2026, and it looks only at the gross income of the borrowers on the loan, not at anyone else in the home.

Note: These figures are revised periodically (the ones above were checked in October 2026), so we verify your eligibility against the current limit when you apply.

How Household Size Affects Your Limit

Under programs that scale by household size, larger households get higher income limits, on the idea that a family of five has more expenses than a single person.

Only some programs work this way: Lighthouse when a round is open, and AMI-based local help such as City of Tucson / Pima County HOME assistance. Each publishes its own table, so check the current one rather than estimating. HOME Plus and the Homebuyer's Solution use the same cap for every household size.

If you're on the edge of qualifying for a program that scales, your household size could make the difference.

What If I'm Just Over the Limit?

This happens more often than you'd think. If your income is slightly over the limit for one program, you might still have options:

Consider a different program. Home Plus, the Homebuyer's Solution and Lighthouse (when a round is open) count income differently. You might exceed one but qualify for another.

Check your calculation. Sometimes people include income that shouldn't be counted, or they're using the wrong household size.

Time your application. If you know a bonus or commission is coming, it might make sense to apply before or after, depending on how that income is calculated.

Explore conventional options. Some lenders offer portfolio products or conventional loans with lender-paid closing cost assistance that don't have income limits.

Common Misconceptions

"I make six figures, so I definitely don't qualify." Not necessarily. HOME Plus and the Homebuyer's Solution set their main cap at $155,386, so six-figure incomes can still fit. Check the program's own limit before ruling yourself out.

"Only one income counts since my spouse won't be on the loan." It depends on the program. Household-income programs can count everyone living in the home, while HOME Plus counts only the borrowers on the loan. Check the specific guidelines.

"I got a raise, so I probably don't qualify anymore." Maybe, maybe not. Income limits are updated periodically too. A raise for you and a limit increase might happen around the same time.

Income limits exist, but they're more generous than many people assume. Don't talk yourself out of exploring DPA before you actually check your eligibility.

Many Tucson buyers who thought they made "too much" were pleasantly surprised to learn they qualified.
