The Quick Read: A new lender counts every lien on the property in its combined leverage test, so an old equity line either gets paid off and closed at closing or it stays in the math, and many lenders count its full credit limit rather than just the drawn balance. The old line does not disappear because you stopped using it. A line you keep open can also require the old lender’s written consent to sit behind the new loan.
- An open line counts in combined leverage, even at a zero balance, until it is closed.
- Some lenders add the drawn balance and others add the full limit, so ask before you apply.
- Paying off and closing the old line at closing is the cleanest path.
- On an investment property, the network’s equity line ceiling is 70% combined loan-to-value, which leaves little room for a large open line.
- A DSCR cash-out refinance is the usual alternative when the old line is in the way.
What Is Combined Leverage, and Why Does the Old Line Sit in It?
Combined loan-to-value (CLTV) adds every loan secured by the property and divides the total by the property’s value. A new lender cannot ignore a recorded lien, because the old line sits on the same collateral it is about to lend against.
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.
Here is how the pieces fit together. The new lender orders a title search and pulls credit. Both show the old line, and the lender then asks three questions:
1. Will the old line be paid off and closed?
2. If it stays, will its lender agree to sit behind the new loan?
3. If it stays, does the new lender count the drawn balance or the full limit?
The third question is where borrowers get surprised. The answer depends on the lender’s method, not on how much you owe today.
Balance or Limit: Which One Gets Counted?
The conventional mortgage world gives a clear reference point, though it does not govern investor loans. Fannie Mae’s home equity combined loan-to-value definition includes the full amount of any HELOC, whether or not funds have been drawn. A mortgage insurer’s training material on calculating these ratios shows the two versions side by side. One counts the drawn portion, and the other counts the full line. The two results differ by exactly the undrawn amount.
Those are conventional definitions. Equity lines and DSCR loans placed through a wholesale network follow each lender’s own method. Across the lenders Lendmire works with, the sensible planning assumption is that an open line counts at its full limit. Treat the drawn balance as the count only when the lender confirms it in writing.
Here is a hypothetical, with every figure expressed as a percentage of property value. Assume an investment property with a first mortgage equal to 50% of value. The old HELOC has a limit equal to 20% of value, and 8% of value is drawn. The new line faces a 70% CLTV ceiling, which is the network ceiling for equity lines on investment properties.
| Method | Liens counted | Combined total | Room under 70% |
|---|---|---|---|
| Drawn balance | 50% + 8% | 58% | 12% of value |
| Full limit | 50% + 20% | 70% | — |
| Old line paid off and closed | 50% | 50% | 20% of value |
The same borrower, the same property, and the same old line produce three different answers. Closing the line is the only version that removes the question.
How Underwriting Treats the Old Line, Step by Step
An equity line file with an old HELOC on it moves through a predictable sequence. Documentation gaps at each step cause most of the delays.
1. Lien discovery. Title and credit show the old line. If a second lien does not appear on credit, the lender needs documentation from you or the creditor. Fannie Mae’s guide uses the same approach, which is why a payoff letter matters even on a line you believe is dormant.
2. Payoff or keep decision. The old line is either paid from the new loan’s proceeds or stays in place. Because the network’s equity line programs require at least 75% of the line to be drawn at closing, a new line has a built-in source of payoff funds.
3. Consent, if the line stays. The old lender controls this step. The Consumer Financial Protection Bureau says you may need your HELOC lender’s approval to refinance a first mortgage. It also says that lender can refuse, and that you may then have to pay off the HELOC to proceed.
4. Leverage test. The new lender compares the combined total to the property value. The value comes from an automated valuation on lines at or below $500,000, which ordinarily involve no traditional appraisal. A full appraisal is required on every line above $500,000, and a borrower may request one in any case. A valuation that lands below what the old lender used raises the ratio even though no balance changed.
5. Debt ratio test. The network’s equity line programs allow up to a 50% debt-to-income ratio, calculated on the interest-only payment on the maximum draw. An old line that stays open usually shows up in the borrower’s obligations under the lender’s method.
6. Release confirmation. If the old line is paid and closed, the lender wants evidence of a recorded release, not only a zero balance.
Three Ways the Old Line Gets Handled
Most files fit one of three structures. Each has a different decision-maker and a different risk.
| Path | What happens | Who decides | Main risk |
|---|---|---|---|
| Pay off at closing | New proceeds retire the line | Borrower and new lender | Payoff exceeds expectation |
| Subordinate | Old line stays behind new loan | Old lender | Consent refused or delayed |
| Pay down, keep open | Line stays, smaller drawn balance | New lender’s method | Full limit still counted |
Paying off at closing is the common route because it moves every decision into one file. The new lender holds the payoff figure and the title company records the release.
Subordination is a favor the old lender grants, not a right you hold. The old lender may refuse, take time, or want a fee. A file that depends on subordination has an outside party that can stop it.
The third path often disappoints. Paying the drawn balance down while leaving the line open helps only if the new lender counts drawn balances. If it counts limits, nothing improves.
What Is the Difference Between a Zero Balance and a Closed Line?
An open line with no balance is still a recorded lien until it is closed and released. The borrower who writes the last payment and assumes the matter is over is the one who gets a surprise at underwriting.
The practical fix has two parts. Ask the old lender for a payoff letter that shows the current limit and balance. Also ask for a written closure request, so the line cannot be drawn again, and then confirm the release is recorded. A balance of zero proves only that you owe nothing today.
Where the General Rule Breaks
Several edge cases change the answer. Each one is worth checking before the file goes in.
A draw before closing. The payoff is measured at closing. A draw taken the week before raises the number the new loan must cover. Freeze the line once you decide to refinance.
A reduced or modified limit. Fannie Mae’s rule for conventional loans allows a permanently reduced limit to be used. If the drawn balance is higher than the modified limit, the balance is used instead. Whether an investor equity lender accepts a reduced limit depends on that lender, so get the lender’s position before you rely on it.
A refused subordination. If the old lender will not sit behind the new loan, the fallback is payoff. A file that cannot fund the payoff has no path, so the question belongs early in the process.
A property held in an LLC. The network’s equity line programs require title in the individual borrower’s name or an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A property already deeded to an LLC needs a vesting change, or a DSCR cash-out refinance instead, subject to lender program eligibility.
Large lines. The maximum investment line in the network is $500,000, and lines above that size are available only on primary residences. An investor with a large existing line cannot count on replacing it with a larger one.
Credit and property type. Investment equity lines in the network require a 700 minimum credit profile. Manufactured homes, co-ops, condotels, log homes, and commercial or mixed-use properties are not eligible.
What the Occupancy Does to the Limit
The ceiling moves with occupancy, so no single number applies to every old-line problem. On an investment property, the network’s equity line ceiling is 70% CLTV at 700 or better credit, up to $500,000. On a second home, the ceiling reaches 90% CLTV, but only at a 720 or better credit profile. On a primary residence, the same 90% ceiling applies at 720 or better and a line up to $500,000.
The old-line math matters most at the low ceiling. On an investment property with a 70% ceiling, an old line that counts at its full limit can consume most of the available room. On a primary residence at a higher ceiling, the same old line leaves more space. This is the main reason investors feel the problem more than owner-occupants do.
A line is also eligible only in first or second lien position, and either way the old HELOC has to be dealt with. If the new line takes first position, the old HELOC needs to subordinate or be paid off. If the new line takes second position, there can be only one second lien, which means the old HELOC has to be paid and closed.
When a DSCR Cash-Out Refinance Handles It Better
An equity line is one tool, and a DSCR cash-out refinance is the other. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. The old HELOC can be paid from the proceeds, which closes the question of whether the old line counts.
Most DSCR cash-out files in the network top out around 75% LTV on standard rentals, with about six months of seasoning commonly expected. A 1.00 coverage ratio is where select programs start, and stronger ratios open better pricing and leverage. Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted. The complete DSCR loans guide covers how the calculation works.
Clearing 1.00 does not mean positive cash flow. DSCR compares rent to the monthly housing payment, and repairs, vacancy, management, and utilities sit outside that calculation.
The Investor Decision in Practice
Four situations cover most of what investors face.
If the old balance is small and you have cash, pay it off before applying. That removes the count, the consent step, and the release question in one move.
If the balance is large, use the new loan’s proceeds to retire it, and confirm that the payoff plus costs fits under the new ceiling. If it does not fit, the new line will come out smaller than the old balance.
If the old lender will not subordinate, plan for payoff or a different structure. A file that depends on a refusal being reversed is a risky file.
If the line is frozen or reduced, treat the number the new lender uses as unknown until the lender states it. Ask for a written answer about whether it uses limit or balance.
Before applying, collect these items:
- The old line’s current limit and current balance, from the old lender.
- A payoff quote, plus a freeze or closure request so the line cannot be drawn again.
- Confirmation of how title is held, since LLC-held property changes the product.
- A short written question to the new lender asking whether it counts limit or balance.
Availability is also narrower for equity lines than for DSCR loans. Lendmire arranges DSCR investor loans across 40 states plus Washington, D.C., while the equity line programs are limited to Lendmire’s 16 full-service states. All figures here are subject to lender guidelines and full file review, and nothing here is a commitment to lend.

Frequently Asked Questions
Does an old HELOC with a zero balance still count against the new limit?
Usually yes, until it is closed and released. A zero balance means you owe nothing, but the line is still a recorded lien with a credit limit attached. Many lenders count that full limit. Closing the line removes it from the math.
Will the new lender pay off my old HELOC for me?
It can, when the new loan is large enough to cover the payoff and costs. The network’s equity line programs require at least 75% of the line to be drawn at closing, so proceeds are available. The payoff is measured at closing, so a draw before then raises it.
What happens if my old HELOC lender refuses to subordinate?
The fallback is paying the old line off. That is the same position the CFPB describes for first mortgage refinances. If you cannot fund the payoff, the new loan may not be able to go forward in that structure.
Is the limit counted the same way on every loan type?
No. Conventional mortgage rules count the full HELOC limit, and investor products follow each lender’s own method. Across the lenders in Lendmire’s network, plan on the full limit unless the lender confirms in writing that it counts drawn balances.
Can a DSCR refinance avoid the problem?
Often, because the old line can be paid from the proceeds and closed. If you want to compare options, Lendmire can help you weigh the property, the equity available, your credit profile, and combined leverage against your goals.
