The Quick Read: Nothing is literally merged; a new first-lien DSCR loan, borrowed by the LLC, pays off the old first mortgage and the HELOC at closing and leaves one lien and one payment. Whether it works depends on two tests at once: appraised value against the combined payoff, and rent against the new, larger obligation.
- The new loan has to cover both payoffs, closing costs, and any cash back to the borrower.
- Most lenders in Lendmire’s network treat a HELOC payoff as cash-out, which tops out around 75% LTV on a cash-out refinance of a standard long-term rental.
- Rent is tested against the full new payment (principal, interest, taxes, insurance, and HOA dues). Clearing the coverage test does not mean the property cash-flows after repairs and vacancy.
- The main cost is giving up a favorable legacy first mortgage. That tradeoff decides most files.
Who Counts as a Portfolio LLC Operator?
A portfolio LLC operator is an investor who holds rentals inside one or more LLCs and runs them as a business. Debt is the daily friction for this borrower. A first mortgage sits on one side and a home equity line sits on the other. The two often come from different lenders and have different payment dates and different draw rules.
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.
This article covers a single-property consolidation, where one rental’s two liens become one DSCR loan. A true blanket loan, with one note across several properties, is a different structure with its own underwriting. Both exist. The mechanics below describe the first.
What “One Loan” Actually Means
One loan means payoff and replace. The lender originates a new first-lien note. At closing, the title company sends proceeds to the old first-mortgage servicer and to the HELOC lender. Both liens are released and the new lien takes first position.
The cleaner version of this is a payoff, not a subordination. Subordination keeps the HELOC alive behind a new first lien, and that requires the HELOC lender’s cooperation. The CFPB notes that a HELOC can affect a first-mortgage refinance, that the HELOC lender may need to approve, and that the lender can refuse. Paying the line off at closing removes that veto.
| Before | After |
|---|---|
| Old first lien | Paid off |
| HELOC lien | Paid off and closed |
| Two payments | One payment |
| Two lenders | One lender |
Why a First Lien Plus HELOC Gets Awkward for an LLC
The awkwardness starts with title. Across the wholesale network Lendmire works with, equity lines on investment property must be held by an individual or a revocable living trust. LLCs, corporations, partnerships, and land trusts cannot hold title on those lines. A rental already deeded into an LLC therefore needs either a vesting change or a DSCR cash-out to reach equity.
That is the strongest reason operators consolidate. A HELOC drawn before the property moved into the entity can become a loose end. The line may still be open, the lien still sits on the property, and the lender may object to the transfer. Consolidating into one entity-borrowed DSCR loan cleans up the title and the debt in one pass, subject to program terms on entity eligibility.
For context, investment-property equity lines cap at $500,000 total, and an LLC-held rental generally cannot use one at all.
How the Lender Tests the Combined Balance
The DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Two tests run side by side, and the tighter one limits the loan.
The value test. The lender adds both payoffs, costs, and any cash back. It compares the total to appraised value. On most files in the network, DSCR cash-out refinances top out around 75% LTV, and about 6 months of seasoning is the common expectation. Heavy HELOC draws can push the stack past that line.
The rent test. The lender divides monthly rent by the new PITIA. The 1.00 level is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger ratios open better pricing and leverage.
Credit matters too. A 620 floor exists in parts of the network, most programs want around 660, and 700 or higher unlocks the strongest leverage tiers. Standard loan sizes run up to $3,000,000 on standard programs (smaller balances available through select lenders). Reserves vary by lender, leverage, and loan size, and commonly land near 6 months of PITIA. Treat each figure as a typical range, not a promise.
Worked Example: One Pass, One Fail
Run the numbers on two modeled files. These are illustrative assumptions, not market data.
Pass case. The old first lien plus the HELOC balance equals roughly 60% of appraised value. Adding costs and no cash back leaves the new loan well under the 75% cash-out cap. Rent covers the new payment at about 1.25x. Both tests clear, and the deal moves on to credit, reserves, and entity review. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Fail case. The first lien is modest, but the HELOC was drawn heavily. The combined stack plus costs reaches roughly 78% of value, which is over the cash-out cap. Rent also covers the larger payment at slightly below 1.00x. The loan amount shrinks to fit the cap, which leaves a gap the investor must fund.
Here the operator has a few paths:
- Pay the line down before applying.
- Look at a select-lender sub-1.00 structure, where leverage and terms adjust.
- Keep the first lien and replace only the line.
- Revisit whether the property belongs in the plan at all.
Qualification stays subject to credit approval and property review.
Combine, Keep, or Pay Down?
| Option | Fits if | Tradeoff |
|---|---|---|
| Combine into one DSCR loan | Title or HELOC is the problem | Reprices the whole balance |
| Refinance first, subordinate HELOC | HELOC is small and cheap | HELOC lender must agree |
| Pay the HELOC down first | Cash is available | Ties up liquidity |
| Keep both | Legacy first is favorable | Two payments remain |
For a broader look at the keep-or-roll decision, see Lendmire’s piece Keeping the First Lien vs Rolling Both Into One Cash-Out Refinance.
When Not to Combine
The whole balance reprices. If the legacy first mortgage carries favorable terms, consolidating gives that up to fix a problem that may be small. The better move may be paying off only the HELOC, or leaving everything alone.
Coverage margin is the second flip point. If rent barely clears the new payment, the file has little room for a vacancy or a repair bill. DSCR counts rent against PITIA only. It ignores repairs, vacancy, management, utilities, and capex, so a 1.00x file can still lose money each month.
An operator with a thin margin and a good legacy loan should usually keep what they have. Consolidation pays off most when title, a stuck HELOC, or portfolio simplicity outweighs the repricing cost.
Where the General Rule Breaks
Rate-and-term turns into cash-out. A file built as rate-and-term can be recharacterized because of a small item in the payoff, such as a line drawn for unrelated purposes, a rolled-in business debt, or modest cash back. Classification is lender policy, so ask early.
Owner-occupied or mixed use. DSCR loans are designed for non-owner-occupied investment property. Because they are business-purpose loans, they are reviewed differently from a standard owner-occupied mortgage. The CFPB’s Regulation Z interpretation deems credit for non-owner-occupied rentals to be business purpose, and it treats credit to a non-natural person separately. An owner who plans to occupy the property falls under different rules.
Business purpose is not a free pass. A Hunton Andrews Kurth paper cautions that business purpose does not mean compliance exempt. It is dated, so use it qualitatively. Keeping cash-out proceeds tied to the rental business is the practical safeguard.
Prepayment terms. Both old loans may carry early-payoff or early-closure fees, and the new loan may carry its own. Read both payoff statements before committing.
A line secured elsewhere. If the HELOC sits on a different property, it is not a lien on this collateral. It can still be repaid from proceeds, but that is a lender-by-lender question.
Ineligible property. Manufactured homes, log homes, and barndominiums are not offered in these DSCR programs. No consolidation structure changes that.
LLC Mechanics: Borrower, Guarantor, and Documents
The LLC is the borrower, subject to program terms on entity eligibility. Many DSCR loans also carry a personal guaranty from the LLC’s principals, so read the guaranty language rather than assuming the entity shields you.
Expect four document groups:
- Entity: formation papers, operating agreement, good-standing certificate, and tax ID letter.
- Guarantor: identification and credit authorization.
- Property: lease or market-rent schedule, insurance, and title work.
- Existing liens: payoff statements for both loans.
Confirm that the signing authority in the operating agreement matches who signs at closing, and that the entity name matches title exactly. Name mismatches cause late surprises.
An appraisal typically supports both value and rent. A single-family property uses the 1004 with a rent schedule, and a 2-4 unit property uses the 1025.
DSCR vs. conventional financing
There are two common ways to finance an investment property, and they qualify you differently — here’s how investors weigh them.
Why investors choose it
- Qualifies on the property’s rental income — no personal tax returns, W-2s, or pay stubs needed to document income.
- No personal debt-to-income ceiling to clear, so existing mortgages and obligations don’t cap your borrowing the same way.
- Can be closed in an LLC, keeping the property inside a business entity.
- Built for scaling — not held to the limit on number of financed properties that conventional financing applies.
- Underwriting centers on the deal: generally qualifies when the rent covers the payment, a 1.00x coverage ratio being a common baseline (confirmed in underwriting).
- Designed specifically for investment property, including long-term and, where the program allows, short-term rentals.
Where it’s strong
- Often the lowest ongoing financing cost for a buyer who fully qualifies on personal income — a fit for a first property or a cost-first purchase.
Trade-offs for investors
- Requires full personal income documentation and must fit within a debt-to-income limit — salary, existing debts, and other mortgages all count.
- Typically held in your personal name rather than a business entity.
- Caps how many financed properties you can carry, which can become a ceiling as a portfolio grows.
- Evaluates you as a borrower as much as the property, which usually means more paperwork.
How investors usually choose: a first or single property often optimizes for the lowest financing cost; portfolio builders often optimize for leverage, vesting in an LLC, and scaling past conventional caps. The right answer depends on your goals, the property, and current guidelines — both paths run through select lenders in Lendmire’s wholesale network, with eligibility and terms confirmed in underwriting.
From Payoff Letters to Closing
1. Request payoff statements for both liens.
2. Confirm the title and vesting match the borrowing entity.
3. Check seasoning and how the HELOC was used.
4. Order the appraisal and rent schedule.
5. Test combined value and rent coverage against program limits.
6. Gather entity and guarantor documents.
7. Close, then get written HELOC close-out authorization and proof of lien release.
Step seven matters. A zero balance does not close a line, so the line stays open until the lender formally closes it.
Key Terms Defined
PITIA: the monthly principal, interest, taxes, insurance, and HOA dues that rent must cover in the DSCR test.
CLTV: the combined loan-to-value ratio, which counts every lien on the property against its value.
Subordination: an agreement that lets an existing HELOC stay in place behind a new first lien.
Cash-out classification: the lender’s label for a refinance that returns cash or pays off certain debts, which usually carries a lower leverage cap.
Recourse: the borrower’s or guarantor’s personal liability for the debt beyond the property itself.

Frequently Asked Questions
Can I merge a first mortgage and a HELOC into one loan?
Not literally. A new first-lien loan pays off both at closing. The old liens are released and one lien remains. The new loan must cover both payoffs plus costs.
Can my LLC be the borrower?
Often yes, subject to program terms on entity eligibility. This is a main reason operators choose DSCR over an equity line, since LLCs generally cannot hold title on investment HELOCs. Confirm entity acceptance and name consistency early.
Does paying off the HELOC count as cash-out?
Commonly yes, unless the line funded the original purchase. Any cash beyond payoffs and costs also makes the file cash-out. A DSCR cash-out refinance typically carries around 75% LTV on a standard long-term rental, subject to lender guidelines.
Do I have to close the HELOC?
Yes, in practice. A zero balance does not end the line. Get written close-out authorization and proof of lien release so the new lender holds a clean first position.
What do I give up by replacing my old first mortgage?
You give up its terms. Because the whole balance reprices, a favorable legacy first lien is the biggest cost of consolidating. If title or the HELOC is not causing a real problem, keeping the first lien may be the stronger choice.
