You can refinance with a high DTI more often than people think. A debt to income ratio over 45% does not end the conversation. Conventional loans can approve up to 50% with an automated approval, FHA and VA streamline refinances usually skip the ratio entirely, and a cash-out refinance that pays off a car loan and credit cards can cut the ratio by 15 points in one closing. With the Freddie Mac average at 7.11% on November 12, 2026, the lowest in seven weeks, more homeowners in Scottsdale, Phoenix, and the rest of Arizona are asking whether their debts will block a refinance. Here is how lenders count it and which path fits which file.

How Lenders Calculate DTI on a Refinance

Your debt to income ratio is your monthly debt payments divided by your gross monthly income. On a refinance, the lender uses the new mortgage payment, not the old one.

The Consumer Financial Protection Bureau defines it the same way lenders do. The housing side includes principal, interest, property tax, homeowners insurance, mortgage insurance, and HOA dues. The debt side is what shows on your credit report: car loans, minimum card payments, student loans, personal loans, plus child support or alimony you pay. Utilities, phone bills, and groceries do not count. Two details trip people up. Student loans in deferment still count, usually at a calculated payment. And a debt you plan to pay off only stops counting if it is actually paid at or before closing.

DTI Limits by Loan Type

The ceiling depends on the loan program and whether a person or the automated system underwrites it. Here is the general picture, before any lender adds its own overlay.

The conventional numbers come from Fannie Mae and Freddie Mac guidelines, and the FHA rules are in HUD's Single Family Housing Policy Handbook. If you already have an FHA loan, our guide to the FHA streamline refinance in Arizona covers the payment benefit test and the timing rules.

A Real Example: 53% DTI to 38%

Here is a composite file we see often in the East Valley: a couple earning $10,000 a month gross who bought in 2024 at 7.875%. Their ratio sits at 53%, which is over the conventional limit.

Housing payment includes an estimated $450 a month for Maricopa County property tax and insurance. Other debts are a $650 car payment, $900 in minimum card payments on $26,000 of balances, and a $400 student loan. The home is valued at $560,000, so the cash-out loan sits under 80% loan to value. Rates are illustrations, and cash-out pricing usually runs a bit higher than rate and term.

The rate drop alone moved the ratio less than three points. Paying off two debts moved it fifteen.

That is the pattern. A small rate improvement rarely fixes a high ratio by itself. Clearing the debts with the biggest payment per dollar owed does. The tradeoff is real, though: you are turning short term debt into 30 year debt secured by your house. Our debt consolidation refinance guide walks through when that math helps and when it hurts.

Run Your Own Numbers

Streamline Refinances That Skip the DTI Check

If you already have an FHA or VA loan, a streamline refinance may be the cleanest route, because it usually does not recalculate your ratio at all.

A non credit qualifying FHA streamline does not verify income. It needs an existing FHA loan, a solid recent payment history, and a net tangible benefit, which usually means a meaningfully lower payment. The VA version, the Interest Rate Reduction Refinance Loan, works similarly, and the VA expects the costs to be recovered through the lower payment within 36 months. Some lenders add their own credit or income checks, which is one reason it pays to shop. Our VA IRRRL guide for Arizona has the details for veterans around Luke Air Force Base and Davis-Monthan.

Conventional borrowers may get something similar later. The mortgage executive order signed October 22 asks the FHFA to consider waiving income re-verification on limited cash-out refinances that lower the payment. That is not in effect, so do not plan around it yet.

Self Employed With a High DTI

Business owners often have a high ratio on paper and plenty of cash in the bank. The fix there is usually the documentation, not the debt.

A full documentation loan qualifies you on the net income from your tax returns, after every write off. If you run a contracting company in Gilbert or a medical practice in Scottsdale and write off aggressively, your qualifying income can look half of what actually comes in, and your ratio balloons. A bank statement loan counts deposits instead, usually over 12 or 24 months, minus an expense factor. Many of those programs allow ratios up to 50%. The rate typically runs higher than a conventional loan, and some carry prepayment terms, so it only makes sense when the conventional path is truly closed. It is also worth checking whether your tax preparer can add back depreciation or a one time expense, since lenders already add some of those back on their own. A second look at the returns sometimes moves a file from denied to approved without changing a single debt.

One more Arizona note. Because Arizona is a community property state, a spouse's debts can come into play on some government loans even when that spouse is not on the refinance, so tell your loan officer about every debt in the household up front.

Lowering Your DTI Before You Apply in Arizona

A few targeted moves in the 30 to 60 days before you apply can drop your ratio enough to switch programs. None of them require a new job.

Pay a car loan down to ten or fewer remaining payments, which many conventional guidelines let a lender leave out of the ratio. Pay a high minimum card to zero rather than spreading cash across every card. Make sure all of your income is counted, including a documented bonus, overtime, or a second job with history. And if a co owner on title earns income but is not on the loan, ask whether adding them helps. Homeowners in Mesa and Chandler who bought at the 2023 and 2024 peak rates are the ones we see most in this spot.
