The Quick Read: On a conventional cash-out refinance, the lender swaps your card minimums for a larger mortgage payment and tests the new total against your income. Paying the cards off at closing can pull their minimums out of the ratio. The bigger mortgage payment then goes in. Whether you net out ahead depends on the size of the balances, the new payment, and the ceiling your file is held to. For most automated approvals that ceiling is 50% of gross monthly income, and cash-out files can be held lower.
Key Takeaways
- DTI (debt-to-income) is your monthly debts divided by your gross monthly income. The new mortgage payment counts.
- Cards paid off at or before closing generally stop counting. The larger mortgage payment replaces them.
- The automated ceiling is 50%. Manually underwritten files use 36% or 45%.
- Cash-out leverage is capped at 80% of value on a one-unit primary residence.
- A lower combined payment can come from a longer term, which can cost more overall.
- You turn unsecured card debt into debt secured by your home.
How Does DTI Work in a Cash-Out Refinance?
DTI is a simple fraction. The top is your total monthly obligations. The bottom is your gross monthly income, before taxes. The lender runs this test on the new loan, not the old one.
The top of the fraction includes the full payment on the new mortgage: principal, interest, taxes, insurance and any association dues. It also includes the minimum payments on the debts that stay behind. Those are car loans, student loans, and any cards you did not pay off.
A cash-out refinance replaces your current mortgage with a new, larger one. You receive the difference as cash, or the lender sends that cash straight to your creditors. For card consolidation, the second route is the usual one. If you want the program overview before the mechanics, Lendmire’s cash-out refinance programs page covers the basics.
Lenders talk about a front-end ratio (housing costs only) and a back-end ratio (housing plus all other debts). On conventional files, the back-end total is the number that decides things. That is the one this article means by DTI.
Here is the thing most consolidation pages skip. A cash-out refinance does not lower your debt. It moves it. The card balances disappear, the mortgage balance grows, and the monthly math changes. Sometimes it improves. Sometimes it does not.
What Counts in Your DTI?
Card minimums count, new mortgage payments count, and debts paid off at closing generally do not. The lender uses the minimum payment shown on your credit report, not what you actually pay each month. A card you pay in full every month still counts at its minimum if there is a balance on the report.
| Item | Counts in DTI? |
|---|---|
| New mortgage payment (P&I) | Yes |
| Property taxes and insurance | Yes |
| HOA or condo dues | Yes |
| Card minimums, cards kept | Yes |
| Card minimums, cards paid at closing | Generally no |
| Car and student loan payments | Yes |
| Groceries, utilities, phone | No |
Under Fannie Mae’s Selling Guide on monthly debt obligations, revolving accounts and unsecured lines of credit are long-term debts. They count in your recurring monthly obligations. The test is about what shows on the credit report and in the file, not what you feel you owe.
How the File Is Underwritten, Step by Step
The lender follows a set order. Knowing it tells you where a file can stall.
1. Application and credit pull. You list the cards you want paid off. The credit report shows each balance and minimum payment.
2. Eligibility screen. The lender checks occupancy, equity, credit score, reserves and seasoning (the waiting period on the loan and your time on title).
3. Underwriting. The new, larger payment goes into the top of the fraction. Cards slated for payoff come out only if the payoff happens at or before closing and is documented.
4. Payoff documentation. The Closing Disclosure shows the payments going straight to your creditors. The lender verifies the funds and the balances.
5. Appraisal. The appraised value sets the maximum loan. The cash-out cap is lower than for a plain rate-and-term refinance, so value drives how much you can pull.
6. Pre-closing recheck. If new debts or lower income surface after the decision, the file can be re-underwritten.
7. Closing. The lender pays the creditors directly. Any cash left over goes to you.
Fannie Mae’s rule on debts paid at or prior to closing sits behind step 3. It says a payoff done solely to qualify must be carefully evaluated in the overall loan analysis. It also says your history of credit use can decide whether a debt is counted or excluded.
In plain words: the underwriter looks at your pattern. A borrower who paid cards down and kept them quiet looks very different from one who refills them every few months.
Lendmire’s piece Conventional Cash-Out Refinance DTI Rules for Debts Paid at Closing goes deeper on this step.
How Paying Off Cards Changes the Ratio
Payoff helps when the card minimums you remove are larger than the extra mortgage payment you add. Payoff does not help when the new payment is bigger than the minimums leaving. The balance moves into a longer-term loan, and the mortgage payment grows more than the minimums shrink.
Here is a before-and-after picture in words, with no dollar figures.
| Item | Before | After payoff |
|---|---|---|
| Current mortgage payment | In the ratio | Replaced by new payment |
| Card minimums | In the ratio | Out (cards paid at closing) |
| New mortgage payment | Not yet | In, and larger |
| Other debts | In | Still in |
Scenario one: payoff helps. Picture a homeowner carrying several cards, each with a minimum payment. Together those minimums eat a big slice of monthly income. The homeowner’s mortgage is small and the equity is large. After consolidation, the new mortgage payment rises modestly, and the card minimums vanish. The total ratio falls, often by enough to clear a tight ceiling.
Scenario two: payoff does not help. Now picture a homeowner with one card balance, a modest minimum, and a mortgage already near the ceiling. Cash-out pushes the loan up to the 80% leverage cap to cover the balance and closing costs. The new payment rises by more than the single minimum that leaves. The ratio goes up, not down. The consolidation adds cost and does not improve the file. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
So the break-even question is simple. Compare the minimums you remove with the payment increase on the mortgage. If the first is bigger, DTI improves. If the second is bigger, it worsens.
Closing costs matter too. They come out of the loan amount or your proceeds. When they eat into the money meant for the cards, the payoff can come up short. A short payoff leaves a card balance in the ratio, and you either bring cash or reduce the payoff list.
What Are the Conventional DTI Limits?
The automated ceiling is 50%. Fannie Mae’s DTI rules set 50% as the maximum for loans run through its Desktop Underwriter (DU). If a recalculated ratio lands above that on a DU file, the loan is not eligible for delivery to Fannie Mae.
Manually underwritten loans are held to 36%, expandable to 45% when the credit score and reserve requirements of the Eligibility Matrix are met. That means the same borrower can get different answers from automated and manual review. Across the wholesale programs Lendmire places files with, the automated finding governs most files.
Do not read 50% as a promise. The same guide notes that for cash-out refinances the maximum DTI can be lower for DU files. DU weighs the whole file: credit, reserves, equity, income stability and the transaction itself. It can reach a lower limit or decline a file at a ratio under 50%. The guide does not give one fixed number for cash-out, so a lender’s decision comes from the DU findings.
Compensating factors are the strengths that let a file carry a higher ratio. These include strong reserves, a high score, low leverage and a stable income history. Under automated review they are baked into the finding. Under manual review they are the key to moving from the base ratio toward the higher manual ceiling.
If a non-occupant co-borrower is on the loan, the ceiling for the occupying borrower on a manual file is lower than 45%. The guide spells out that exception.
What Else Is Reviewed Alongside DTI?
DTI is one gate among several. A file that clears the ratio can still fail on equity or seasoning. These figures are subject to lender guidelines and full file review.
| Requirement | Conventional cash-out (primary home) |
|---|---|
| Max LTV, one unit | 80% |
| Max LTV, two to four units | 75% |
| Credit score floor | 620 at the wholesale level |
| First mortgage seasoning | At least 12 months |
| Time on title | 6 months |
| Appraisal | Required; sets the loan cap |
LTV (loan-to-value) is your loan balance divided by the home’s appraised value. At 80% LTV you must keep at least 20% equity after the new loan. Many consolidation borrowers run into this cap before they run into DTI. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Seasoning has two parts. The mortgage being paid off must be at least 12 months old, counted from note date to note date. You must also have been on title for 6 months. Exceptions exist for delayed financing after a cash purchase, inheritance, and legal awards.
Cash-out loans also carry pricing adjustments built into the loan’s cost. They are described in the Loan Estimate and are not a separate line you can negotiate away. Mortgage insurance is required above 80% LTV on most conventional loans. A wholesale lane reaches 80% LTV with no mortgage insurance. It needs a 680 score, a 50% ratio on a thirty-year fixed loan, a primary residence, a conforming balance and its own six months of seasoning. In Texas, a cash-out on a homestead is capped by the state constitution, and that lane is not written there.
Where the Rules Bend or Break
- Cards left open. Fannie Mae policy generally lets a card paid to zero at closing stay open, and no payment is counted. The lender can still weigh your credit-use history when deciding.
- Collections, charge-offs and judgments. These are treated differently from cards. Payoff is required at or before closing. Check the exact thresholds with your lender.
- Thirty-day charge accounts. The lender must verify enough funds to cover the balance on top of closing costs and reserves.
- A spouse who is not on the loan. The lender looks at the borrower’s own obligations. Paying a non-borrowing spouse’s debts may not help your ratio.
- Limited cash-out (rate-and-term). This is a different product. It allows only small cash back, and it cannot pay off credit cards. Fannie Mae’s limited cash-out rules explain the line between the two.
- Second homes, investment properties and multi-unit homes. Occupancy sets the leverage. Anything other than a one-unit primary home carries a lower cash-out cap.
- State law. Some states add limits on cash-out. Texas is the best-known case.
- FHA and VA. They follow different DTI and cash-out rules. This article covers conventional loans only.
What If Your DTI Is Too High?
Four levers move the ratio. Each has a trade.
| Lever | Effect on DTI | Tradeoff |
|---|---|---|
| Pay off more cards | Removes more minimums | Needs more equity or cash |
| Pay down a car loan first | Removes a fixed payment | Uses cash you may need as reserves |
| Add a qualifying co-borrower | Adds income | Adds their debts and credit |
| Take a smaller cash-out | Lowers the new payment | Leaves some cards unpaid |
Lenders also look at income that is documented and likely to continue. Raising a number on paper does not help if the file cannot support it.
A longer term can also lower the payment. Watch that one. A lower payment may only reflect a longer repayment period, and that can mean paying much more over time, fees included.
Risks to Weigh Before You Consolidate
You swap unsecured debt for secured debt. The Consumer Financial Protection Bureau warns that using a home equity loan to consolidate credit card debt is risky, because you could lose your home in foreclosure if you do not repay. Defaulting on a card is unlikely to cost you the house. Defaulting on a mortgage can.
You use up equity. Equity can leave you underwater if values fall, and it may be out of reach in an emergency.
Balances can come back. A CFPB research report on cash-out refinances and paydown behavior found that paying off other bills was the most common reason borrowers took cash out. Card balances fell sharply after the refinance, then drifted back up. If spending is the cause, the new loan fixes the symptom and leaves the cause.
Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit.
Pre-Application Checklist
1. Pull your credit report and list every card with its balance and minimum payment.
2. Add up your gross monthly income from all borrowers on the loan.
3. List your other monthly debts: car, student, personal loans.
4. Note your current mortgage payment, taxes, insurance and any dues.
5. Estimate your home’s value and your loan balance, then calculate your LTV.
6. Check the age of your current mortgage and how long you have been on title.
7. Decide how much you need for payoff versus how much extra cash you want.
8. Ask whether the lender wants the cards closed or left open.
9. Compare the combined payment with your current obligations before you proceed.

Frequently Asked Questions
What DTI do I need for a conventional cash-out refinance to pay off credit cards?
The automated ceiling is 50%, and manually underwritten files use 36% or 45%. Cash-out files can be held lower than 50% depending on how DU assesses risk and the Eligibility Matrix. Your lender can tell you the finding on your file, subject to lender guidelines.
Does paying off cards before I apply change my DTI?
Yes, if the balance is paid to zero, since no minimum remains to count. But a payoff done only to qualify gets a close look. The lender weighs your credit-use history. Paying cards down with your own cash also reduces the money available for reserves.
Do I have to close the credit cards I pay off?
Not under the debts-paid-at-closing policy, which generally lets a card paid to zero stay open. The lender can still weigh your history. If balances have bounced back before, expect a closer look at whether the cards stay open.
Will the new mortgage payment make my DTI worse?
It can, depending on how the numbers net out. The larger mortgage payment goes into the ratio, and the card minimums come out. When the extra mortgage payment exceeds the minimums removed, the ratio rises. Compare the two numbers before you apply.
Is a cash-out refinance better than a personal loan or balance transfer?
It depends on your equity, your DTI and your appetite for risk. Cash-out can reach larger balances and can stretch the term, which can cost more in total. It also puts your home behind the debt. A personal loan or balance transfer keeps the debt unsecured.
