The Quick Read: A DSCR cash-out refinance suits investors who want one new loan that pays off the old first mortgage, the HELOC, and the card balances at closing, while resubordination suits investors whose current first mortgage is worth protecting and whose HELOC lender is willing to sign. Neither option is better in the abstract. The choice turns on three things: your equity, your existing lien terms, and whether the HELOC lender cooperates.
- Cash-out refinance: one lender, one payoff, one new first lien. A standard rental cash-out typically tops out around 75% LTV across most of the network.
- Resubordination: you keep the HELOC, and its lender agrees to sit behind a new first mortgage. That lender has no duty to say yes.
- Card debt is the sticking point in both: paying personal cards with property-secured money changes the risk, and use-of-proceeds rules vary by lender.
- Equity decides most files: if the combined balances already sit near the ceiling, there may be no room to roll cards in at all.
Here is the honest version. Cash-out is for the investor who wants a clean slate and has the equity to fund it. Resubordination is for the investor who is happy with the existing first mortgage and wants to add or keep a junior line without disturbing it. Both routes put unsecured card balances on a rental, and that tradeoff deserves more weight than the paperwork.
How large a line the equity supports.
An equity line is sized by combined loan-to-value, occupancy, and credit — not by rental coverage. Switch the occupancy or the credit band and the ceiling moves with it.
Investment-property lines require a 700 minimum credit score; second-home lines start at a 640 minimum and primary-residence lines at 600, and the combined-LTV ceiling steps down as the credit band drops on primary-residence and second-home lines and holds on investment-property lines; the line cap steps down on primary-residence lines and holds at every tier on investment-property and second-home lines.
A debt-to-income ratio above 45% requires 680+ credit. Profiles under 640 are limited to single-family homes. At least 75% of the approved line is drawn at closing. Ceilings, floors, and caps update from Lendmire’s centralized guideline source.
Line estimate
Illustrative estimate only — not a quote, Loan Estimate, approval, or commitment to lend. The rate is an editable assumption; equity-line pricing is variable through both the draw and repayment periods and never converts to fixed. Occupancy and credit drive the ceiling together: an investment property tops out at 70% combined LTV (minimum credit 700, line cap $500,000); a second home tops out at 90% combined LTV (minimum credit 640, line cap $500,000), with the ceiling stepping down as the credit band drops (the cap holds at every tier); a primary residence tops out at 90% combined LTV (minimum credit 600), and its $750,000 maximum line is available only at 75% combined LTV or below with a 700-or-better credit profile (720 on the longer-runway program) and a full appraisal. Lines above $500,000 require a full appraisal. Credit, debt-to-income, property type, and full underwriting review all affect the final line.
Key Terms Defined
Several terms get used loosely on this topic, so here is how this article uses them.
Lien position is the order in which lenders get repaid if the property is sold or foreclosed. The first lien is paid first.
Subordination is a written agreement in which a junior lender agrees to stay behind a new senior loan. Resubordination is the same idea applied again: a HELOC lender that already sat behind one first mortgage is asked to sit behind a replacement. People search with either word, and lenders use them interchangeably.
CLTV (combined loan-to-value) adds every loan on the property, first and junior, and divides by the property’s value.
DSCR (debt service coverage ratio) compares a rental’s income to its full monthly obligation: principal, interest, taxes, insurance, and any association dues. A DSCR cash-out refinance is a new loan on a rental that qualifies primarily on property-level rental income covering the payment, subject to lender guidelines, and that returns equity as cash.
An investment-property HELOC is a revolving line of credit secured by a rental, usually in second position behind an existing first mortgage.
Side-by-Side
The table below compares the structure of each route. The second column describes how resubordination generally works, based on published industry norms. The HELOC lender you already have sets its own terms.
| Factor | DSCR cash-out refinance | HELOC kept via resubordination |
|---|---|---|
| Review basis | Rent covering the payment (DSCR) | HELOC lender’s review of credit and file |
| Personal income review | Property-income focus, per program | Usually credit and income reviewed |
| Property types | 1-4 units, condos, STR per program | Varies by HELOC lender |
| Entity vesting | Entity or individual, per program | Often individual or revocable trust |
| Approvals needed | One lender; HELOC paid at closing | New first lender plus HELOC consent |
| Reserves | Commonly about 6 months of PITIA | Varies; first lender’s rules still apply |
| Leverage ceiling | 75% LTV on standard rental cash-out | Combined leverage must fit both lenders |
| Card payoff | Paid from the closing proceeds | Paid by a HELOC draw or new funds |
PITIA means principal, interest, taxes, insurance, and association dues, the full monthly cost of holding the loan. Reserves are cash or liquid assets you keep after closing. They vary by lender, leverage, loan size, and transaction type.
One more row belongs in your mind even though it is not in the table: timing and control. A cash-out refinance has fewer parties, so fewer things can stall. Resubordination adds a second approval from a lender that has little reason to help.
Why a Refinance Forces the Subordination Question
Liens follow a simple rule: first in time, first in right. Nolo’s legal encyclopedia explains that when a first mortgage is refinanced, the old loan is paid off and the existing second mortgage moves up to first position. The new lender then lands in second place.
No new first-mortgage lender will accept that. So the junior lender must either sign a subordination agreement or be paid off. Subordination changes only the order of repayment, and it does not rewrite the HELOC’s other terms.
One wrinkle matters for investors. A HELOC is second only when a first mortgage exists. Bills.com notes that on a property owned free and clear, the HELOC is the first lien. In that case the argument for protecting a low-balance first mortgage disappears, and the comparison gets simpler.
When a Cash-Out Refinance Is the Better Fit
A cash-out refinance is the better fit when the HELOC lender is unlikely to cooperate, the combined balances are large, or you want to simplify. It replaces the whole stack with one first lien and pays the cards at closing. You deal with one lender instead of two.
The HELOC lender won’t sign, or you can’t count on it. A junior lender has no obligation to subordinate. If it refuses, the refinance stalls. A cash-out that is large enough to pay off the HELOC removes the question entirely, because once the second lien is released there is nothing left to subordinate.
Your existing first mortgage has no special value. If its terms are ordinary, or you were going to refinance anyway, you give up little by replacing it. Rolling everything into one loan also leaves a single payment and a single set of maturity dates.
The property is reviewed on its own rent. Across most programs in the network, a cash-out refinance on a standard rental tops out around 75% LTV, and about 6 months of seasoning is the common expectation. Coverage of 1.00 is where select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger coverage opens better leverage and pricing.
You hold the property in an entity. An LLC-titled rental can be refinanced subject to lender program eligibility. A standalone HELOC generally cannot do that, as covered below.
On credit, a floor of 620 exists in parts of the network, and most programs want around 660. A score of 700 or better unlocks the strongest leverage tiers. Standard loan sizes reach up to $3,000,000 on standard programs, with smaller balances available through select lenders, and above $2,500,000 the network generally holds to 30-year fixed structures. For the full program picture, see Lendmire’s complete DSCR loans guide.
Two cautions apply. First, a bigger first-lien balance lowers coverage, because the same rent now covers a larger payment. Clearing 1.00 also does not mean the property produces spendable cash. Repairs, vacancy, management, utilities, and capital expenses all sit outside the calculation. Second, short-term rentals run tighter: a cash-out on short-term-rental collateral caps at 70%, against 75% on a standard long-term rental, and expects about 12 months of hosting history.
When HELOC Resubordination Is the Better Fit
Resubordination is the better fit when your current first mortgage is something you want to keep, the HELOC is already in place, and the junior lender is willing to stay behind a new first. It is also a fit when you want revolving access rather than a one-time lump sum.
The existing first mortgage is worth keeping. If you have no reason to touch it, a junior line leaves it undisturbed. The legacy first stays exactly as it is, and the HELOC sits behind it. If you do need to refinance the first, resubordination keeps the line alive through the swap.
The HELOC balance is small relative to the property. A small junior balance is easier for the junior lender to accept behind a new first. A big one makes that lender less comfortable, because a larger first-lien balance pushes its own position further down.
You want flexibility, not one lump sum. A HELOC is a revolving, open-end line. Per the CFPB’s HELOC explainer, a lender may freeze or reduce a line if the home’s value drops significantly or the borrower’s finances change. That risk matters if you counted on the line as a standing reserve.
You are adding a new line, not keeping an old one. Lendmire also brokers standalone investment-property HELOC lines through select wholesale partners. The parameters are narrow:
- The ceiling on an investment property is 70% CLTV, with a 700 minimum credit score.
- The maximum line is $500,000, and there is no larger investment tier.
- The line runs a 5-year draw followed by a 25-year repayment period. At least 75% of it is drawn at closing, and it is variable and never converts to fixed.
- Lines at or below $500,000 ordinarily run an automated valuation instead of a full appraisal, though a higher CLTV may call for a second valuation.
- DTI (debt-to-income) can reach 50%, calculated on the interest-only payment at the maximum draw.
- Eligible properties include single-family, 2-4 units, PUDs, townhomes, and condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.
- Title must be held by the individual borrower or a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title.
- A borrower is limited to three lines, and one with more than 15 financed properties is not eligible.
- These lines are placed only in Lendmire’s 16 full-service states, which is narrower than its DSCR footprint of 41 markets, including Washington, D.C.
Every figure is subject to lender guidelines and full file review. A primary-residence line follows a different set of tiers, so this article keeps to rentals.
The vesting rule is the sharpest structural difference between the two options. A rental already deeded to an LLC cannot carry this kind of line without a title change. In that case a DSCR cash-out is usually the cleaner route.
How Resubordination Actually Works
Resubordination follows a sequence, and each step depends on a lender that is not you.
1. A new first-lien loan pays off the old first mortgage, and the old lien is released.
2. The new first lender requires first position as a condition of the loan.
3. The HELOC lender receives a request to subordinate. It reviews the new loan amount, your combined leverage, and your credit.
4. The HELOC lender decides. It can agree, decline, or ask you to pay down the balance.
5. If it agrees, the signed subordination agreement is recorded with the new mortgage, and the HELOC stays open behind the new first.
Card payoff can happen in two ways. You can draw on the HELOC to pay the cards, which adds no new money from the refinance. Or a new loan can pay the cards while the HELOC stays subordinated. Drawing the HELOC just before a planned refinance creates a bigger balance for the junior lender to accept behind the new first, so sequencing matters.
A zero-balance HELOC is still a recorded lien until it is formally closed and released. Do not assume an unused line disappears on its own. Ask the title company how it will be handled.
Tell your lender about the HELOC upfront. Surprises on the title report can slow a file down. If the HELOC lender asks for the new loan terms and your combined leverage, giving them cleanly and early can help.
What If the HELOC Lender Says No?
The usual fallback is a payoff, which means paying the HELOC off and closing it as part of the refinance. That is where the two options in the title meet. A refusal turns resubordination into a cash-out or a rate-term refinance with a HELOC payoff.
Ask the HELOC lender three questions before you commit to this path:
- What combined leverage will you accept behind a new first mortgage?
- What documents do you need, and from whom?
- Does a cash-out amount for card payoff change your answer?
If the answers are vague, plan for the payoff route from the start. Waiting for a refusal late in the process is the way files stall.
The Real Risk: Turning Card Debt Into Property-Secured Debt
Credit cards are unsecured. A HELOC or a cash-out refinance is secured by the rental. If you fall behind on a HELOC, the CFPB warns you could lose the home, and the same logic applies to a rental pledged as collateral. Card debt that could once be negotiated now has a lender with a lien.
There is also a purpose question. DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage. The federal rule on business-purpose credit, reproduced in Cornell’s legal reference, treats credit to acquire, improve, or maintain a non-owner-occupied rental as business purpose. Paying off personal cards is not on that list, so how a lender treats that use of proceeds varies. Disclose the plan for the cash up front and confirm how your lender handles it.
On the tax side: tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
Finally, a cash-out that clears the cards does not clear the habit that built them. A rental carrying a larger balance has less margin for a vacancy. Plan for the case where the cards fill back up.
Run the Numbers: Two Scenarios
These examples use percentages of property value only, to show the structure.
Scenario one: room to spare. Say a rental carries a first mortgage near 55% of value and a HELOC near 10%. The card balances equal about 8% of value. Rolling everything into one standard cash-out refinance lands near 73% combined, under the 75% ceiling on a long-term rental. The refinance can pay off both liens and the cards, subject to lender guidelines and coverage. Resubordination is also possible, but it adds an approval step without adding value.
Scenario two: no room. Now say the first mortgage sits near 60% and the HELOC near 12%. That is already 72% combined. A cash-out with a 75% ceiling leaves about 3% of value, far too little to retire meaningful card debt. Here the real options are paying down the cards another way, selling a different asset, or leaving the stack alone.
Coverage is a second test. A larger first-lien balance lowers the DSCR, because the rent stays the same while the payment grows. Strong files clear both tests: enough equity and enough rental coverage.
The choice is a genuine toss-up when equity is moderate and the first mortgage has favorable terms. Resubordination preserves those terms, but it depends on a lender that owes you nothing. Cash-out gives up the old terms but removes the dependency. For many investors, certainty is worth more than keeping a legacy loan.
Balanced Verdict
Choose a cash-out refinance if you want one lender, one payoff, and no dependence on a junior lender’s cooperation. It fits best when you hold the property in an entity, when the property’s rent supports the larger payment, and when the existing first mortgage is not a prize.
Choose resubordination if the first mortgage has terms you want to protect, the HELOC balance is modest, and the junior lender has signaled it will sign. It also fits if you need a revolving line rather than a lump sum.
Choose neither if combined leverage is already near the ceiling or if card debt is a recurring pattern. Putting unsecured debt onto a rental raises the stakes, and the better answer may be a different structure.

Frequently Asked Questions
Can I keep my HELOC when I refinance my first mortgage?
Sometimes. The HELOC lender must agree to sign a subordination agreement, and it has no obligation to do so. If it declines, you can pay the line off at closing or fold it into a cash-out refinance.
Does subordination change the terms of my HELOC?
It changes lien priority only. The HELOC lender agrees to repayment behind the new first mortgage, and the line’s other terms generally stay as written. Your lender’s own paperwork controls the details.
Is a HELOC always a second lien?
No. On a rental owned free and clear, the HELOC is the first lien, and there is nothing to subordinate to until a new first loan is added.
Can an LLC hold a HELOC on a rental?
Not on the investment lines Lendmire places. Title must be held by the individual or a revocable living trust. A rental already deeded to an LLC would need a vesting change, or a DSCR cash-out instead.
Does a DSCR cash-out refinance need my personal income documents?
It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Credit, reserves, and property eligibility still matter, and use-of-proceeds questions for personal card payoff are reviewed program by program.
