The Quick Read: The lender tests your debt-to-income ratio (DTI) on the picture after closing, not the one you walk in with. Debts paid off at closing generally drop out of the ratio. The new, larger mortgage payment goes in. Whether your DTI improves depends on one thing: whether the payments you remove add up to more than the housing payment grows.
Paying debts with cash-out does not shrink what you owe. It moves the debt into the mortgage. On paper the ratio can look better, worse, or about the same. This guide walks through the mechanics, step by step, so you can tell which one you are facing before you apply.
Cash-out refinance estimate
The starting figures are an example value with a balance and a cash request in proportion. Replace them with yours.
Editable benchmark: 7.18% as of November 5, 2026 · Freddie Mac 30-year average via FRED®. A conventional market reference, not a cash-out refinance quote.
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.
What Is DTI, and Why Does It Decide This Loan?
DTI is your total monthly debt payments divided by your gross monthly income. Gross means before taxes. Lenders often split it into two views. Front-end DTI counts only housing costs. Back-end DTI counts housing plus every other monthly debt.
Housing cost here means principal, interest, taxes, insurance, and any association dues. On a 2-4 unit home you live in, that payment covers the whole building, not just your unit.
On the wholesale conventional programs, the automated underwriting finding governs most files, with a total ratio ceiling of 50%. Manually underwritten loans use 36% or 45% tiers, tied to the reserve and credit-score factors in the Fannie Mae Eligibility Matrix. The matrix also ties extra reserves to cash-out loans with higher DTI. Every figure is subject to lender guidelines and full file review.
How Is the Loan Underwritten, Step by Step?
The lender treats your loan as a cash-out refinance the moment proceeds pay off debts, then runs the ratio on the post-closing picture. Here is the sequence.
1. Classify the loan. Paying off non-mortgage debts makes it a cash-out refinance, not a rate-and-term (limited cash-out) refinance. Leverage limits and pricing adjustments follow the cash-out label.
2. Check eligibility. For the conventional cash-out, the mortgage you are paying off must be at least 12 months old, counted note date to note date. At least one borrower must have been on title for 6 months, with exceptions for delayed financing, inheritance, and legal awards.
3. Build the “before” debt list. The lender pulls your credit report and collects payoff statements. Installment loans, credit cards, support obligations, and leases all go on the list.
4. Decide what gets paid at closing. The closing instructions send funds straight to creditors. Debts shown as paid in full drop out. Debts left open stay in, at their monthly payment.
5. Compute the “after” housing payment. On a 2-4 unit home you occupy, Fannie Mae’s automated underwriting includes the proposed payment on the subject property in your total expenses, per its job aid on rental income. That payment now sits on a bigger balance.
6. Add rent used for lender review, if any. More on this below.
7. Appraise the building. A 2-4 unit needs a multi-unit appraisal that supports both value and rent. Value drives the loan-to-value (LTV) test, which caps how much cash you can take.
8. Run the final ratio. The result depends on post-closing DTI, leverage, credit score, reserves, and documentation.
9. Fund. Payoffs go to creditors. Whatever remains is your actual cash out.
What Leaves the Ratio, and What Enters It?
The simplest way to see it is a ledger. Some items leave. Some enter. Some stay.
| Item | Effect on DTI |
|---|---|
| Credit card paid at closing | Leaves the ratio |
| Installment loan paid at closing | Leaves the ratio |
| Old first-mortgage payment | Replaced by new payment |
| New, larger housing payment | Enters the ratio |
| Collections, judgments, liens | Must be paid, not simply excluded |
| Debts you leave open | Stay in at current payment |
Fannie Mae’s Selling Guide counts every debt you owe unless a named exclusion applies. Its topic on debts paid off at or before closing is the payoff rule, and revolving balances paid at closing need no monthly payment in the ratio. The guide’s debt-obligations section is B3-6-05.
Do you have to close the cards? Under that guidance, a paid revolving account does not have to be closed to drop out of DTI. A lender can still add its own conditions, so ask early.
How Does Rental Income From the Other Units Count?
Rent from the units you do not live in can help you qualify, but only a portion counts and only with documentation. Rent from your own unit generally does not count. Boarder income and accessory-unit situations are the usual exceptions.
Fannie Mae sets its own rules for rental income on a 2-4 unit principal residence, and your loan officer can tell you which version applies to your file. In practice the file includes the multi-unit appraisal (Form 1025) and a rental income worksheet (Form 1037), with rents stated separately by unit. FHA requires fair-market-rent evidence from the appraisal when there is little or no rental history, per HUD Mortgagee Letter 2023-17.
Agencies apply a haircut or a payment-based limit to the rent. The exact factor varies by agency and by guideline version, so ask your loan officer which one applies to your file rather than assuming a percentage.
Here is the catch. Counted rent offsets the housing payment, but it does not erase it. A larger loan means a larger payment, and the rent credit may cover only part of that growth.
A Worked Example With Three Paths
Picture a homeowner living in one unit of a fourplex, with the other three units rented. Income is steady. The monthly debts are a mortgage, two credit cards, a car loan, and a personal loan. No dollar figures here, just direction.
| Scenario | Debts leaving | Housing payment | Net DTI direction |
|---|---|---|---|
| Keep the cash | None | Larger | Up |
| Pay all debts | Cards, car, personal | Largest | Depends on break-even |
| Pay only high-payment debts | Highest-payment ones | Larger, but less | Depends on break-even |
Path one is a plain cash-out. The loan grows, the housing payment grows, and no other debt leaves. DTI rises.
Path two pays everything. Several payments disappear, but the loan balance jumps by the full payoff amount. If the payments removed exceed the housing payment increase, DTI falls. If not, it rises.
Path three sizes the cash-out to retire just the debts whose monthly payment is large next to their balance. A card with a large minimum and a modest balance helps the ratio far more than a loan with a low payment and a big balance. Because the loan grows by less than in path two, the housing payment rises by less, though the result still turns on the same break-even comparison.
When Does Paying Off Debt Backfire?
Payoff backfires when the housing payment increase exceeds the payments you remove. That is the break-even test, and it is worth running before you commit.
Add up the monthly payments of the debts you plan to retire. Then estimate how much the new housing payment rises. Your loan officer can estimate the increase without quoting you a price. If the first number is bigger, DTI improves. If the second is bigger, it worsens.
Three patterns can trip this up:
- Low-payment, high-balance debts. Paying off a loan with a small payment and a large balance adds a lot to the mortgage and removes little from the ratio.
- Nearly finished installment loans. Some installment debts with few payments left can be excluded without payoff, per guideline. Ask your loan officer to confirm the guideline before spending cash-out on them.
- Debts left open. If one balance slips through unpaid, its payment stays in.
There is also a plain trade-off. Moving unsecured debt into a mortgage stretches the repayment period and puts your home behind the debt. Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit.
Where the General Rule Breaks
These edge cases change the answer. Know them before you submit.
Debts someone else pays. A debt another person pays can be excluded, but only with the most recent 12 months of canceled checks or bank statements from the payer showing no late payments, per the same Selling Guide section. Verbal assurance does not count.
Business debt in your name. It can be excluded with evidence the business paid it from company funds, such as 12 months of canceled company checks.
IRS installment agreements. The payment can drop out only if it meets the exclusion terms. Otherwise the balance must be paid at or before closing.
Collections, charge-offs, judgments, and liens. These generally must be paid, not skipped.
Government streamlines. The FHA Streamline and the VA IRRRL are no-cash-out products for existing FHA or VA loans. Neither can pay off other debts. Debt payoff on an FHA or VA loan means a full cash-out refinance with full underwriting. For FHA, a non-occupant co-borrower’s income cannot be used to qualify a cash-out.
Energy-retrofit liens. Freddie Mac treats some of these payoffs as no-cash-out and others as cash-out, depending on the lien.
State rules. Some states have separate rules for cash-out loans. In Texas, a cash-out on a homestead is capped at 80% of the home’s value by the state constitution, and the wholesale no-mortgage-insurance lane is not written there.
How Much Cash Can You Actually Take?
On a conventional cash-out, leverage tops out at 80% LTV on a one-unit principal residence and 75% on a two- to four-unit principal residence. Occupancy sets the leverage, so a 2-4 unit lands lower than a single-family home. That ceiling limits how much debt you can fold in. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Equity, not DTI, is often the first wall. A low appraisal shrinks the cash available, which can leave some debts unpaid and in the ratio. Because the agency cash-out ceiling sits at or below 80%, mortgage insurance rarely comes into play on that path. The exception is a wholesale no-mortgage-insurance cash-out lane reaching 89.99% LTV for a primary residence, which requires a 680 score and a 50% ratio on a 30-year fixed with a conforming balance, and has its own six months of seasoning. Whether a 2-4 unit fits that lane is a file-by-file question.

Should You Run the File With and Without Rent?
Yes, when rent is close to the line. Sometimes the file works on income alone and rent only adds paperwork. Other times the rent credit is what gets the ratio under the ceiling. Ask for both versions.

Pre-Application Checklist
- List every debt, payment, and balance.
- Rank debts by payment relative to balance.

- Collect rent roll and leases for the other units.
- Confirm the loan being paid off is at least 12 months old.
- Ask for the file to be run with and without rent.
Frequently Asked Questions
Does paying off debts at closing always lower my DTI?
No. It lowers DTI only when the payments removed exceed the increase in your housing payment. Documentation also has to show the debts were paid in full.
Do I have to close my credit cards after the payoff?
Generally no. Fannie Mae guidance excludes a paid revolving balance without requiring the account to be closed. A lender can add its own conditions, so confirm before closing.
Can I count rent from the unit I live in?
Generally not. Rent from your own unit is excluded, apart from boarder income and accessory-unit exceptions. Rent from the other units can count in part, with a multi-unit appraisal and rent documentation.
Can an FHA Streamline or VA IRRRL pay off my credit cards?
No. Both are no-cash-out refinances of an existing government loan. Paying debts requires a full cash-out refinance with full underwriting.
What is the maximum DTI on this loan?
It depends on the underwriting path. Across the wholesale conventional programs, the automated finding governs most files with a 50% ceiling, and manually underwritten loans use 36% or 45% tiers with reserve and score factors. All of this is subject to lender guidelines and full file review.
