Cash-Out Refinance Debt-to-Income — The Quick Read: Your debt-to-income ratio on a cash-out refinance is the new housing payment plus the debts that stay, divided by your qualifying income. Debts paid off at closing drop out of the math. The new mortgage payment usually goes up. So the ratio improves only when the payments you retire outweigh that increase. Everything here is subject to lender guidelines and full file review.
What Is a Cash-Out Refinance, and Why Does DTI Change?
A cash-out refinance replaces your current mortgage with a larger one and pays you the difference, or pays your creditors directly. On a home you live in, conventional programs generally cap the new loan at 80% of the home’s value on a one-unit principal residence. Two- to four-unit homes, second homes and investment property cap at 75%.
Debt-to-income (DTI) is your total monthly debt payments divided by your gross monthly income. Gross means before taxes. Lenders use it to judge whether you can carry the loan.
Here is why it moves on a cash-out. Your mortgage balance grows. Your payment on it usually grows too. At the same time, you may pay off credit cards, auto loans or personal loans at the closing table. Those payments disappear from the ratio. The final number is the net of those two moves.
If you want to see the programs themselves, Lendmire’s cash-out refinance programs page lays out the loan options. Lendmire is a mortgage broker. It arranges these loans through wholesale lenders and does not lend directly.
Key Takeaways
- DTI has two parts: monthly obligations on top, qualifying income on the bottom.
- Debts paid off at or before closing are left out of the ratio.
- The bigger mortgage payment is the main swing factor. It can cancel out the benefit.
- A true cash-out refinance gets a full DTI recalculation. Streamline-type refinances mostly do not let you pay off consumer debt.
- The ceiling is not one national number. It depends on the program, the underwriting path and the lender.
Key Terms Defined
Debt-to-income ratio (DTI): Your total monthly debt payments divided by your gross monthly income.
PITIA: Principal, interest, taxes, insurance and association dues. It is the full monthly cost of owning the home.
LTV (loan-to-value): The loan amount as a percentage of the home’s value.
Seasoning: The waiting period that must pass before a refinance is allowed, such as how long you have owned the home or held the current loan.
Automated underwriting: Software that reviews the whole file and returns a finding. Fannie Mae’s version is called DU.
Manual underwriting: A person reviews the file against fixed guidelines, usually with tighter ratio limits.
Limited cash-out refinance: A rate-and-term refinance. It pays off the old loan and costs, with only small cash back.
How Is DTI Calculated on a Cash-Out Refinance?
The formula has two parts. Per the Fannie Mae Selling Guide on debt-to-income ratios, DTI is total monthly obligations divided by the total monthly income of all borrowers, to the extent that income is used to qualify.
On the debt side, a principal residence counts the full housing payment: principal, interest, taxes, insurance and association dues. Then the lender adds the rest:
- Installment loans with more than ten months left.
- Alimony, child support or maintenance running beyond ten months.
- Revolving accounts that stay open with a balance.
- Other recurring obligations.
- Any net rental loss.
That is the “before” snapshot. The cash-out changes two things in it: the housing payment and the list of debts that remain.
The Net-Out Mechanic: Paid-Off Debts Drop Out
Debts you pay off at or before closing do not count against you. Fannie Mae’s rule on debts paid off at or prior to closing says an installment loan paid down to ten or fewer remaining payments does not need to be included. It also says a revolving balance paid off at or before closing carries no monthly payment in the ratio.
Here is the part people miss. You do not have to close the card account. The payment is excluded because the balance is zero, not because the account is gone. A lender can add its own conditions, though. Fannie Mae lets lenders be more conservative as long as they apply the approach consistently.
A Walk-Through With Made-Up Numbers
These figures are invented for illustration only. They are not quotes, and no real payment amounts are used. Think in units instead of dollars.
Say your gross monthly income is 100 units. Run the numbers on this borrower:
- Current mortgage payment: 25 units.
- Credit cards, auto loan and a personal loan: 15 units combined.
- Current DTI: 40 units of debt over 100 units of income, or 40%.
Now the cash-out. The new, larger loan pushes the housing payment to 30 units. You use the proceeds to pay off the cards and the personal loan, which together carried 10 units. The auto loan, at 5 units, stays.
- New housing payment: 30 units.
- Remaining auto loan: 5 units.
- New DTI: 35 units over 100, or 35%.
The ratio improved by five points even though the mortgage payment rose. That is the good case.
Now flip it. Suppose the new housing payment jumps to 38 units because you took out a lot of cash for other reasons, and only 5 units of debt got paid off. Your new total is 38 plus 10 remaining, or 48%. Same borrower, worse ratio.
So the rule is simple. A cash-out lowers DTI only when the retired payments are bigger than the added mortgage payment. It does not lower DTI automatically.
Which Debts Actually Disappear From the Ratio?
The answer depends on how the debt is set up. Run through these cases:
- Revolving accounts (credit cards): Paid in full at or before closing, the payment is excluded. The account can stay open.
- Installment loans (auto, personal, student): Excluded once paid off. Also excluded if paid down to ten or fewer remaining payments.
- Student loans not paid in full: The lender must include a monthly payment amount in your obligations.
- Alimony and child support: Counted if they run beyond ten months.
- IRS installment agreements: Fannie Mae allows an approved, documented, current agreement as a monthly obligation. Otherwise it must be paid off at closing.
On ten-month debts, one more wrinkle. Fannie Mae’s archived guide on debt-to-income ratios notes that payments on short-term debts may still count if they significantly affect your ability to meet obligations. That archived page is older, so treat the detail as a pointer and not as today’s wording. A lender can still look past the label.
What Limits Does the Lender Apply?
There is no single national DTI limit. The ceiling depends on the underwriting path, the program and the lender.
Across the wholesale conventional programs I work with, the automated finding governs most files. The total ratio ceiling there is 50%. Manually underwritten loans run at 36% or 45%, depending on the reserve and score factors in the Eligibility Matrix. Credit starts at a 620 decision score on the conventional programs, and 640 on an adjustable rate under manual underwriting. These are program guidelines, not promises. Each lender can set stricter rules.
Two details matter for cash-outs specifically. First, the agency guide lists cash-out refinances as an exception to the usual maximum, and the cap can be lower on files run through automated underwriting. Second, higher ratios on a cash-out can trigger a reserves requirement. Reserves are cash or liquid assets left after closing. Ask your loan officer whether your ratio puts you in that zone.
One more point on the rulebook. The old 43% cap on “qualified mortgages” no longer sets a limit. The Consumer Finance Monitor explains that a price-based test replaced it. Lenders still must consider DTI or residual income and document a good-faith ability-to-repay decision.
Who Qualifies for a Cash-Out in the First Place?
Before DTI even matters, the loan has to be eligible. Based on the conventional programs I place files with, you need:
- Seasoning on the current loan: The first mortgage being paid off must be at least 12 months old, measured note date to note date.
- Time on title: At least one borrower on title for 6 months. Delayed financing, inheritance and legal-award exceptions exist.
- Leverage within the cap: 80% LTV on a one-unit principal residence. The Fannie Mae Eligibility Matrix publishes its own caps by occupancy and transaction type.
- Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
One wholesale lane goes further. It reaches 89.99% LTV with no mortgage insurance. That lane needs a 680 score and a 50% ratio on a thirty-year fixed rate, primary residence, conforming balance, with its own six months of seasoning. In Texas, a cash-out on the homestead is capped by the state constitution at the agency figure, and that wholesale lane is not written there. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
If you are wondering about a second home or a rental, the answer is one sentence: occupancy decides the leverage, and the caps drop to 75% for those properties.
Where the Rule Breaks: Edge Cases
The general idea holds up well, but a few cases bend it.
Streamline and IRRRL loans do not consolidate debt. The FHA Streamline and the VA IRRRL are rate-driven products for people who already have an FHA or VA loan. No cash comes out on a Streamline, per the FDIC summary of the FHA Streamline. Both require a net tangible benefit, meaning the refinance must clearly help you. The FHA Streamline has no appraisal and a limited credit review. The VA IRRRL has no VA appraisal and uses a benefit test in place of a DTI test. If you want to retire cards or a car loan, you need a true cash-out.
Rate-and-term refinances can’t pay consumer debt either. A limited cash-out refinance allows only the old first mortgage, closing costs and a purchase-money second lien to be paid off, with only incidental cash back. Paying off a non-purchase second lien or a credit card makes it a cash-out. Mortgage insurance applies above 80% LTV on the rate-and-term side. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Debts paid by someone else. A lender may exclude a payment made by another person, but it wants documented proof of the payment history.
Co-borrowers on FHA cash-outs. FHA does not allow income from a non-occupant co-borrower on a cash-out. Rental income from an accessory dwelling unit cannot be used to qualify either.
High-LTV refinance exceptions. Fannie Mae’s high-LTV refinance has no maximum DTI under certain paths. That is a narrow program. Do not assume it applies to you.
Co-op shares. The matrix prohibits cash-out on second-home co-op share loans.
Why Do Closing Timing and the Payoff List Matter?
The lender builds the payoff list into the loan file. Your title or settlement agent normally pays the creditors directly from the loan proceeds, so the balances reach zero at closing. Confirm that handling with your own lender. The key is to name each debt on the list, since a debt left off keeps its payment in your ratio.
If you pay a debt down but not fully, the lender counts what remains. For installment loans, that means the payment is excluded only if the debt is paid off or paid to ten or fewer payments left.
What Does the Borrower’s Decision Look Like?
DTI is the lender’s test. It is not your test. A loan can pass the ratio and still be a poor choice for your budget.
The CFPB’s guide on using home equity points out that a cash-out can lengthen your term and raise your monthly payment, because you replace the current loan with a larger one. Your ratio can look better while your household cash flow still has to carry a bigger mortgage.
There is a risk shift too. A CFPB report on cash-out refinances and debt paydown notes that converting non-mortgage debt into home-secured debt puts the home at risk if payments become unsustainable. Missing a credit card payment is unlikely to cost you the house. Missing a mortgage payment can.
The same report says paying off non-mortgage debt can make sense if the cost of pulling out the cash is less than the cost of continuing to pay down the higher-interest debt. And watch the behavior trap. The CFPB found that credit scores jump after a cash-out, then drift down, and that card balances rose in the year after the refinance. A paid-off card is only paid off until you use it again.
If you are asking whether the move is worth it, this guide on whether to cash-out refinance to pay off debt walks through the decision itself.
A Checklist Before You Apply
1. List every monthly debt and its remaining payments. 2. Mark which ones you would pay off at closing. 3. Estimate how much the new mortgage payment would rise. 4. Compare the retired payments to that increase. 5. Check whether your remaining ratio fits the program’s ceiling. 6. Ask for the Loan Estimate and read the closing costs line by line.
Closing costs vary by lender. Some people roll them into the loan. That raises the balance and the payment. Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit.
What Mistakes Do Borrowers Make?
Practitioner view: the same errors show up again and again across the files I see.
- Assuming the payment shrinks. A bigger loan means a bigger payment in most cases.
- Forgetting the debts that stay. One leftover car loan can hold the ratio above the line.
- Leaving a debt off the payoff list. It keeps counting.
- Thinking the card must be closed. It does not, though a lender may add its own conditions.
- Running the ratio only once. Your DTI gets recalculated on the new loan. Do the math before you apply, not after.
- Using up the cash on other things. Every extra dollar borrowed raises the housing payment and the ratio.
Decision Table: Which Refinance Fits Which Goal?
| Goal | Better fit | Pays off consumer debt? |
|---|---|---|
| Retire cards and auto loans | Conventional cash-out | Yes |
| Lower the payment on an FHA loan | FHA Streamline | No cash out |
| Lower the payment on a VA loan | VA IRRRL | No |
| Swap the old loan, keep it simple | Rate-and-term | Only incidental cash back |
| Pull equity above the conforming limit | Jumbo lane | Program-dependent |

Frequently Asked Questions
Does cash-out refinancing always lower my DTI?
No. It lowers DTI only when the debts you retire carry more monthly payments than the new mortgage adds. If you take out extra cash or only pay off small debts, the ratio can go up.
Do I have to close my credit cards after paying them off?
Not under Fannie Mae’s rule. A revolving balance paid off at or before closing carries no counted payment, and the account can stay open. A lender may set stricter conditions, so ask yours.
Can I pay off only some of my debts at closing?
Yes. The debts you pay off drop out of the ratio, and the ones you leave stay in. Pick the payoffs that cut the most monthly obligation, since that is what moves the number.
What is the maximum DTI for a cash-out refinance?
On the conventional programs I place, automated findings allow up to 50%, and manual underwriting runs at 36% or 45%. Higher ratios can bring a reserves requirement, and cash-outs can face a lower cap than other loans.
Can I use an FHA Streamline or VA IRRRL to consolidate debt?
No. Both are designed to reduce the cost of an existing FHA or VA loan, and neither lets you take cash out to pay off consumer debt. For that you need a true cash-out refinance.
