The Quick Read: An investment property line of credit can pay off an older HELOC, and a DSCR cash-out loan can do the same job, but the right route depends on which property secures the old line, how much combined leverage the new loan allows, and whether the old lender will release or subordinate its lien.
- A DSCR loan sits in first lien position, so an old HELOC behind it must be paid off, subordinated, or paid down first.
- An investment-property line through Lendmire’s network tops out at 70% combined loan-to-value, up to $500,000, with a 700 minimum credit score.
- A DSCR cash-out refinance on a standard long-term rental tops out around 75% LTV across most of the network, with about 6 months of seasoning as the common expectation.
- A zero balance does not close a HELOC. The line must be formally closed and the lien released.
- Clearing the coverage test does not mean the property cash flows, because repairs, vacancy, and management sit outside the ratio. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Which Path Are You On?
The title can describe two different deals, and mixing them up wastes weeks of confusion. Here are the three real paths, side by side.
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.
| Path | What happens | Best fit |
|---|---|---|
| Replace line with new line | New investment line pays off the old HELOC | Owner holds title personally, wants a line again |
| Roll into DSCR cash-out | New first-lien loan pays off first mortgage and HELOC | Wants one fixed-term loan, coverage is solid |
| Refinance first, keep HELOC | DSCR loan replaces the first; HELOC stays behind it | Old lender agrees to subordinate |
The first path is the literal reading of the title. A new investment-property line is a standalone line that can sit in first or second lien position, so it can replace an older line on the same rental. The second path works because a first-lien DSCR loan can absorb both liens in one payoff. The third path depends entirely on the old HELOC lender’s cooperation.
Throughout this article, “the old line” means the HELOC you already have. “The new loan” means whichever product replaces it.
Key Terms Defined
DSCR (debt service coverage ratio): The monthly rent divided by the property’s monthly housing obligation, meaning principal, interest, taxes, insurance, and any HOA dues.
HELOC: A revolving credit line secured by property, with a draw period when you can borrow and a repayment period when you cannot.
CLTV (combined loan-to-value): All loans secured by the property added together, divided by the property’s value.
Subordination: A written agreement where an existing lender agrees to stay behind a new first mortgage in lien order.
Payoff letter: A lender-issued document stating the exact amount needed to retire a loan on a specific date, which is different from a statement balance.
Lien release: The recorded document proving a lender no longer has a claim on the property.
Seasoning: The waiting period a lender wants between events, such as buying or refinancing a property and the next refinance.
Why Investors Move Off an Old HELOC
The most common trigger is a line that is changing shape. A HELOC has a draw period and a repayment period. The CFPB’s HELOC booklet explains that some plans allow interest-only payments during the draw, that rates are typically variable, and that payments can change even if you draw nothing more. When the draw ends, the lender may set a schedule to repay the full balance, often over 10 or 15 years, or the whole balance may come due at once.
Experian reports that draw periods typically run 5 to 10 years, usually followed by a 20-year repayment period. Terms vary by lender, and some lines carry a balloon payment.
An investor sitting at the end of a draw period is looking at a payment that stops being interest-only and starts amortizing. That is payment shock, and it is a legitimate reason to refinance.
There are other reasons as well:
- A bank can freeze or reduce a line if credit or finances worsen. A term loan cannot be taken away that way.
- A bank line is reviewed around personal income and debt-to-income. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. That helps investors with many properties or tax returns that understate cash flow.
- A fixed-term loan is easier to plan around than a floating line.
One point matters here. An investment-property line through our network floats, and the pricing never converts to fixed. A new line replacing an old line fixes the lien problem but not the variable-payment problem. If payment stability is the goal, the DSCR route is the one that delivers it, since the spine of DSCR lending is the 30-year fixed.
How Underwriting Treats the Old Line, Step by Step
Underwriters care about three things: lien order, combined leverage, and whether the rent covers the new payment. Here is how a file moves through those checks.
1. Pull the facts on the old line. Get the payoff letter, the credit limit, whether the line is in draw or repayment, and its lien position. Note what the line originally funded.
2. Confirm which property secures it. A line on your primary home or on a different rental is not a lien on the subject rental. It needs no payoff or subordination on this refinance.
3. Choose the path. Pay it off inside the new loan, ask for subordination, or pay it down first from other funds.
4. Run combined leverage. If the old line stays open, the whole credit limit usually counts toward leverage, not just the drawn balance. A line you barely use can still eat your leverage room.
5. Test the rent. The appraiser typically completes a single-family or 2-4 unit appraisal with a rent schedule, and the lender compares market or lease rent to the new payment. Credit, insurance, and entity documents are reviewed too. Reserves vary by lender, leverage, loan size, and transaction type, and commonly run around 6 months of PITIA.
6. Close and release. The title company pays the old line from proceeds and records the release. You sign a closure request so the line cannot be drawn again.
7. Confirm afterward. Check that the lien release was recorded and that the old line no longer allows draws.
Coverage deserves a plain warning. A DSCR calculation compares rent to the subject property’s housing obligation only. Whether a remaining line’s payment enters the coverage math depends on the lender, so ask early. Either way, your bank account still pays that line, and clearing the ratio is not the same as positive cash flow.
On coverage, 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger coverage opens better pricing and leverage.
What an Investment-Property Line Can and Cannot Do
An investment-property line is narrower than most investors expect. Here are the parameters on files we place, always subject to lender guidelines and full file review.
- Leverage: 70% CLTV on an investment property. A 700 and a 720 credit profile both reach that same ceiling, so a higher score buys eligibility rather than extra leverage.
- Size: lines run up to $500,000 on investment properties. Larger lines are limited to primary residences.
- Credit: 700 is a hard floor for investment property.
- Structure: a 5-year interest-only draw followed by a 25-year fully amortizing repayment. At least 75% of the line is drawn at closing.
- Valuation: at or below $500,000, lines ordinarily run on an automated valuation with no traditional appraisal, though a higher CLTV may require a secondary valuation.
- Debt-to-income: 50% maximum, qualified on the interest-only payment calculated on the maximum draw.
- Property types: single-family, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not eligible.
- Exposure: a borrower is limited to three lines, and an owner of more than 15 financed properties is not eligible.
- Availability: the equity-line programs are offered in 16 states, narrower than the 41-market DSCR footprint (40 states plus Washington, D.C.)
The sharpest difference from a DSCR loan is title. Title must be held by you personally or by a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on the line. A rental already deeded to an LLC needs a vesting change or a DSCR cash-out instead. DSCR loans to LLC-titled entities are available subject to lender program eligibility.
Which Property Secures Your Current Line?
This is the question most investors skip, and it changes everything. Use this table before anything else.
| Old line secured by | Lien on subject rental? | Next step |
|---|---|---|
| This same rental | Yes | Payoff, subordination, or paydown |
| Your primary home | No | Leave it alone; refinance the rental separately |
| A different rental | No | Same, handled on its own file |
| Nothing (unsecured) | No | Not a lien issue at all |
A common confusion comes up in the second row. Investors sometimes believe a HELOC on their home blocks a DSCR refinance on a rental. It does not. The two properties are separate collateral. What the lender will look at is the credit report, because the line shows up there.
A Worked Example With Percentages
Here is a modeled scenario. The inputs are assumptions, not market data.
Say a rental carries a first mortgage equal to 50% of its value, plus a HELOC with a limit equal to 20% of value, of which half is drawn (10% of value).
- If the HELOC stays: combined leverage counts the whole limit, so it reads as 70% of value. A new first mortgage would have to leave that room intact, and the HELOC lender must agree to subordinate.
- If a DSCR cash-out pays off both: the payoff is 60% of value (50% first plus 10% drawn). On a standard long-term rental, a cash-out refinance tops out around 75% LTV, which leaves up to about 15% of value before closing costs and reserves.
- If the rental is a short-term rental: the cash-out ceiling drops to 70% LTV on short-term-rental collateral, which leaves about 10% of value before costs. Expect a 640+ score and about 12 months of hosting history. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Now the coverage test. Suppose the rent covers the new loan’s full monthly obligation at roughly 1.15x. That clears the benchmark many select programs use. It says nothing about what remains after repairs, vacancy, and management.
The alternative is a new investment line at the 70% ceiling. In the same example, the existing first stays at 50% of value, so the line has room for up to 20% of value. Paying off the old HELOC’s drawn balance (10% of value) would use only half of that room, so the new line could leave about 10% of value available as cash. Subject to a 700 credit score and personal title, that works. The tradeoff is that a floating line replaces a floating line. Every figure here varies by lender and program, and guidelines, property type, leverage, and credit profile all apply.
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.
Where the General Rule Breaks
Paying off a HELOC is usually treated as cash-out. That is the working rule. The agency version is spelled out in Fannie Mae’s Selling Guide, which treats paying off a non-purchase-money second lien as a cash-out refinance, and requires a second left in place to be resubordinated. DSCR loans are not agency products, and each program sets its own rules, so treat that as context only. Across our network, a HELOC payoff is generally priced and capped as cash-out.
The exceptions are real, though:
- The HELOC financed this rental’s purchase. Some lenders may treat the payoff as rate-and-term, but that is lender-specific and typically requires documents proving where the proceeds went.
- The line has a zero balance but is still open. It is still a lien. It must be closed and released.
- Subordination is refused. Large retail lenders often decline on investment properties, especially when a cash-out refinance grows the first lien. The fallback is payoff, paydown, or skipping the refinance.
- The existing first mortgage is cheap. Replacing a good first just to remove a HELOC may not pay off. A separate second-lien product may fit better.
- The property is in an LLC. The investment line is off the table. A DSCR loan to an LLC-vested rental can work, subject to program terms.
- The property was recently bought or refinanced. Seasoning applies, with about 6 months the common expectation on cash-out.
- A prepayment penalty applies. A recently placed DSCR loan can carry one, so check the existing note before refinancing out of it.
- Property type. DSCR loans are not offered on manufactured homes (single- and double-wide), log homes, or barndominiums.
Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.
Credit history can also redirect the plan. On investment files, a bankruptcy needs 4 years of seasoning from discharge or dismissal. A foreclosure follows a 7-year path, and a deed-in-lieu, pre-foreclosure, or short sale a 4-year path. On the DSCR side, a 620 score floor exists in parts of the network, most programs want around 660, and 700+ unlocks the strongest leverage tiers.
Deciding in Practice
Start with the easiest question: does the old line even touch this rental? If not, leave it alone. If it does, the decision runs through four checks.
1. Is the line near the end of its draw period? If yes, the urgency is real.
2. Does the rent cover a new first-lien payment with room to spare? If coverage is thin, a smaller loan or a different product may work better than forcing a cash-out.
3. Does your combined leverage fit? Remember that DSCR cash-out ceilings are lower than purchase ceilings, which reach 75%-80% LTV on most files.
4. Will the old lender subordinate? If not, payoff is the path.
When the answers line up, a DSCR cash-out that retires both liens is the cleanest result: one loan, one lien, one fixed-term structure. When they do not, a new investment line, a paydown, or staying put can be the better call. This one is a real toss-up for investors with a cheap first mortgage, because the DSCR route trades away that cheap first to remove the HELOC.
Loan sizes for DSCR files run up to $3,000,000 on standard programs (smaller balances available through select lenders), and above $2,500,000 the network generally holds to 30-year fixed structures. Extended terms, interest-only periods, and ARM structures are available through select lenders for investors who want them.
A larger down payment or more equity can lift coverage, but it never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage. For the full picture of how these programs fit together, see Lendmire’s complete DSCR loans guide.
Frequently Asked Questions
Do I need the old lender’s permission?
Only if the old line stays in place. A payoff needs no permission, just a payoff letter and a signed closure request. Subordination is a favor the old lender can refuse, and many do on investment properties or cash-out deals.
Can a DSCR loan sit in second position?
Generally no. A DSCR loan is a first-lien product. If you want a line alongside it, the usual order is the DSCR loan first, then a line behind it, if a lender allows one.
Can I refinance a HELOC on my home using a rental’s equity?
Yes, in principle, through a DSCR cash-out on the rental whose proceeds you use to pay down the home line. The home line is separate collateral, so you handle it on its own. Cash-out leverage, seasoning, and reserves all apply to the rental.
What if my rental is in an LLC?
The investment-property line cannot be used, because title must be held personally or in a revocable living trust. A DSCR loan to an LLC-titled rental may work, subject to lender program eligibility. A vesting change is the other option.
What if the rent does not cover the new payment?
You have options. A smaller loan amount can lift the ratio. Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted. Or the line-for-line route avoids the coverage test on the first mortgage entirely, though it carries its own qualification on credit and debt-to-income.
