The Quick Read: Yes. Every cash-out refinance has a debt-to-income (DTI) limit, but no single national number applies. DTI is your total monthly debt payments divided by your gross monthly income. The limit depends on the loan program and on how the lender underwrites the file. On a conventional cash-out loan, the automated finding governs most files, with a total ratio ceiling of 50%, subject to lender guidelines and full file review.
How Does DTI Work on a Cash-Out Refinance?
A cash-out refinance replaces your current mortgage with a larger one and pays you the difference. The lender counts the new, bigger payment when it measures your DTI. Taxes, insurance, and any HOA dues go in too.

Illustrative starting assumptions: a $350,000 home value, a $193,000 current balance, the agency cap on a one-unit principal residence, a thirty-year term at the current Freddie Mac benchmark, and property taxes and insurance estimated at typical national rates. Every field is editable.
Illustrative estimate only — not a Loan Estimate, approval, quote, or commitment to lend. The rate field carries the weekly Freddie Mac thirty-year conventional benchmark, a market reference and not a cash-out refinance quote; a cash-out loan is priced by the lender at lock. The cash available is the loan the program cap allows less the balances paid off, before closing costs, which are not included. The HELOC line is the program’s combined loan-to-value ceiling applied to the same value and balance. Taxes and insurance are editable estimates. Licensed in sixteen states for consumer mortgages.
Here is the formula in plain steps:
1. Add up your monthly debts: the new mortgage payment, car loans, student loans, minimum card payments, and support payments.
2. Divide that total by your gross monthly income (before taxes).
3. The result is your DTI, expressed as a percentage.
The federal consumer-finance regulator says different loan products and lenders have different DTI limits. That is the whole story in one sentence. Anyone quoting you “the” DTI cap is skipping a step.
The surprise for most homeowners is the before-and-after effect. Your current ratio uses your old payment. The lender tests the ratio with the new payment, and that payment is larger because the loan is larger. A file that looks comfortable today can look stretched once the cash is added to the balance.
What Is the DTI Limit on a Conventional Cash-Out Loan?
For conventional loans, the automated underwriting finding sets the ceiling, and it tops out at 50%. Manually underwritten loans are held to 36%, or 45% when you meet the credit score and reserve factors of the Eligibility Matrix.
Fannie Mae’s own rule, Selling Guide B3-6-02, confirms the split: a 50% maximum for automated underwriting and 36% to 45% for manual. Check the current guide for exact wording.
An automated finding can allow a higher ratio, and a manual file with compensating factors can reach the upper end of the manual range. The same split applies to 2–4 unit properties.
| Underwriting path | Typical ceiling | Notes |
|---|---|---|
| Automated finding | 50% | Weighs the whole file |
| Manual, base | 36% | Fixed ceiling |
| Manual, with factors | 45% | Needs score and reserves |
Rates are not quoted here.
Why do the numbers differ? The FHFA Inspector General notes that the two enterprises’ limits differ based on whether the loan runs through an automated or manual system. Manual underwriting falls back on fixed ceilings. Automated underwriting looks at the whole risk picture.
Does a Cash-Out Loan Have Stricter DTI Rules Than a Rate-and-Term Refinance?
Often, no. A rate-and-term refinance, also called a limited cash-out refinance, pays off your existing first mortgage and closing costs, with only incidental cash back. It is still fully underwritten, so DTI applies. But leverage caps are higher: up to 95% LTV on a one-unit principal residence, against 80% for cash-out. LTV, or loan-to-value, is your loan balance divided by the home’s appraised value.
Cash-out gets a harder look because you are pulling equity out. Higher leverage plus a larger payment is a bigger risk to the lender. That is also why cash-out files carry a reserve trigger. The Fannie Mae Eligibility Matrix says minimum reserves apply to automated cash-out files with a DTI above 45%. Reserves are verified cash you still have after closing.
How Do FHA and VA Handle DTI?
FHA and VA both treat DTI as one factor, not a single hard wall.
FHA. HUD capped cash-out loans at 80% of adjusted value in Mortgagee Letter 2019-11. For DTI, FHA weighs the whole file, and the ratio limits depend on the underwriting path, including the automated scorecard finding. The applicable ratio moves with the path and with lender overlays.
VA. VA treats DTI as a guide. VA Pamphlet 26-7, Chapter 4 says DTI is secondary to residual income. Residual income is what is left of your monthly income after taxes, debts, and living costs. A ratio above 41% draws close scrutiny. An automatically closed loan above 41% needs a justification signed by the underwriter’s supervisor. That requirement falls away if residual income beats the guideline by at least 20 percent.
Here is the catch: many lenders set their own stricter caps than the agencies. The same veteran can get different answers from different lenders.
Is 43% a Legal Limit?
No. A lot of people still believe it is. The old 43% cap for General QM loans was replaced by a price-based test, per an NAHB summary of the CFPB rule. Lenders still have to consider and verify your income and debts, and weigh DTI or residual income. So there is no federal cap on a refinance. The real limits come from the program and the lender.
Which Refinances Skip the DTI Check?
Only the streamlines, and not all of them. A streamline gives you no cash, so a cash-out is never a streamline.
- VA IRRRL. It is for an existing VA loan, with no cash out. Lenders typically don’t re-underwrite income. Confirm the details with VA, since lender practice varies.
- FHA Streamline. Your loan must already be FHA-insured and current, and the refinance must produce a net tangible benefit, per HUD. There are two tracks. The credit-qualifying track asks for income and credit documentation. The non-credit-qualifying track does not.
If you want the cash, you are on a fully underwritten path, and DTI applies.
What Else Counts Besides DTI?
DTI never decides alone. The lender weighs it with credit, LTV, reserves, and income stability. A strong score does not erase a high ratio, because hard ceilings still apply. Other pieces on a conventional cash-out:
- Leverage. 80% LTV on a one-unit principal residence, 75% on two- to four-unit principal residences.
- Seasoning. The first mortgage you are paying off must be at least 12 months old, and you must have been on title for 6 months. Delayed financing, inheritance, and legal-award exceptions exist.
- Credit. The wholesale conventional programs start at a 620 decision score.
- A no-mortgage-insurance lane. One wholesale lane reaches 89.99% LTV with no mortgage insurance at a 680 score and a 50% ratio, on a thirty-year fixed, primary residence, conforming balance. It has its own six months of seasoning. In Texas, a homestead cash-out is capped by the state constitution, and that lane is not written there. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Everything here is subject to lender guidelines and full file review. None of it is a commitment to lend.
What If Your DTI Is Too High?
You have more options than most people think. Walk through them in this order.
1. Pay off debts at closing. Cash-out proceeds can retire debts, and a debt paid off at closing may leave the ratio. The lender confirms how each account is treated.
2. Borrow less. A smaller cash-out means a smaller payment and a lower ratio.
3. Add documented income. Co-borrower income or other stable, documented income raises the denominator.
4. Build reserves. Verified cash after closing can strengthen a borderline file.
5. Switch programs. A different underwriting path may treat the same file differently.
6. Use a no-cash refinance. If the goal is a better term, rate-and-term may fit.
Watch one pitfall. Paying off cards with home equity only helps if the cards stay at zero.
A quick scenario. Say a homeowner earns a steady salary and carries a car loan and two credit cards. Her current ratio sits near the middle of the range. She wants cash for a renovation, and the new payment lifts her ratio past 45% on the automated path. The fix is to roll the card balances into the loan and borrow a little less for the renovation. The cards drop out of the ratio and the loan shrinks. Her file may now fit the automated ceiling, subject to the lender’s review.
Key Terms Defined
DTI (debt-to-income ratio): Your total monthly debt payments divided by gross monthly income.
LTV (loan-to-value): The loan balance divided by the home’s appraised value.
Reserves: Verified cash or liquid assets you still hold after closing.
Residual income: The money left each month after taxes, debts, and living costs; VA weighs it first.
Seasoning: The waiting period a lender wants on your existing loan or title before you can cash out.
Lender overlay: A rule a lender adds on top of the agency minimums.
Frequently Asked Questions
Can I get a cash-out refinance with a DTI over 45%?
Sometimes. On a conventional automated file, the ceiling is 50%, and reserves are required once DTI passes 45%. Manual files are held lower. Lender overlays can set the bar below that. Your file is reviewed as a whole, subject to lender guidelines.
Does my DTI affect my credit score?
No. Credit bureaus don’t use income to calculate scores. A hard inquiry at application can touch your score, but DTI itself does not. DTI matters because lenders use it to judge whether you can carry the payment.
Does a co-borrower help with DTI?
It can, when the co-borrower’s income is documented and counts toward qualifying. Their debts count too. A co-borrower who does not live in the home is treated differently under agency rules, so confirm the specifics with your loan officer before relying on it.
Is the DTI rule different for a duplex I live in?
The ratio logic is the same, but leverage drops. A one-unit principal residence cash-out reaches 80% LTV, and a two- to four-unit principal residence reaches 75%. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Do two lenders give the same DTI answer?
Not always. Agencies set the outer limits, and each lender can add stricter overlays. That is why a broker who shops multiple wholesale lenders can surface a different answer on the same file.
Where Does This Leave You?
DTI is a gate on every cash-out refinance, but the gate has several widths. Know your number with the new payment in it, and know which underwriting path your file will take.
