The Quick Read: No bank list exists for this, because the lender holding your existing line decides whether it can stay open behind the new first mortgage, the refinance lender cannot override that choice, and the outcome is usually one of three paths: subordinate the line, pay it off, or replace it later. Which path fits depends on combined leverage, credit, and how the property is titled.
- The refinance pays off the old first mortgage, so the HELOC becomes the oldest lien unless its holder agrees to sit second again.
- The HELOC holder can refuse, and a refusal usually means paying the line off to refinance.
- Combined loan-to-value is tested on the full credit limit, not the drawn balance.
- Folding the line into the new loan changes how the refinance is classified, which can affect leverage limits.
- Investment-property lines are harder to find, so closing one can mean losing it for good.
Who Is the “Bank” in This Question?
The word “bank” points to three different lenders, and each has a different role. Mixing them up is why searches for a bank list go nowhere.
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.
The first is the new first-mortgage lender. It writes the refinance and sets conditions, including what must happen to the open line. The second is the existing HELOC holder. It owns the decision that matters most, because it controls whether its lien stays in second position. The third is a new junior lender, which only matters if you want a fresh line after the refinance.
A bank that offers a HELOC today may refuse to subordinate it tomorrow. A lender that writes great refinances may have no interest in sitting behind someone else’s line. So the useful question is not which banks do this. It is which lender will consent for your file, at your leverage, on your property type.
Lendmire is a mortgage broker, not a lender. It places files with a network of wholesale lenders, which lets a scenario be matched to a program instead of tested one bank at a time.
Why a Refinance Disturbs an Open HELOC
A refinance pays off the old first mortgage and releases its lien. As bills.com explains, the HELOC then becomes the oldest recorded lien and moves into first position. The new first-mortgage lender will not close in second position.
The fix is a subordination agreement. The HELOC holder signs a document agreeing to stay behind the new first mortgage. Once it is signed and recorded, the line can generally stay open and you can draw on it again.
Three points shape every file:
1. The HELOC holder decides. The refinance lender can ask for subordination. It cannot compel it.
2. The full limit counts. Combined loan-to-value uses the whole credit line. bills.com advises adding the new first-mortgage balance to the full HELOC limit before you apply.
3. Old consent does not carry over. A subordination signed for the old first mortgage covered only that loan. A new refinance means a new request.
Key Terms Defined
Lien position: The order in which recorded loans are paid if the property is sold or foreclosed. Earlier recording means earlier payment.
Subordination agreement: A signed document in which a lender agrees to keep its lien behind another lender’s lien.
Resubordination: A second subordination request, made when the first mortgage is replaced and the earlier agreement no longer applies.
Combined loan-to-value (CLTV): All liens on the property, using the full HELOC limit, divided by the property value.
Cash-out refinance: A refinance that pays off debts or returns funds beyond the old first mortgage. Paying off a HELOC in the loan usually puts it in this category.
The Three Paths, Side by Side
| Path | Who must consent | Main risk |
|---|---|---|
| Keep the line, subordinate | HELOC holder | Request refused |
| Pay off and close the line | Nobody extra | Line may be hard to replace |
| Pay off now, new line later | New junior lender | Title, credit, or leverage limits |
Keep the line and subordinate. This preserves the existing credit line and its terms. The cost is the consent request, which is the step most likely to stall. Paying the balance down first does not remove that request, because the holder must still approve staying open behind the new loan. If the holder declines, the refinance lender generally requires payoff and closure.
Pay it off and close it. The refinance lender sees one clean first lien. The catch is classification. Folding the HELOC into the new loan typically makes the whole transaction a cash-out refinance, even when no cash reaches you. That can change the leverage ceiling and the seasoning review.
Pay it off, then open a new line. This works only if a lender will write the new line on your property type and title, covered below.
How the HELOC Holder Decides
The HELOC holder treats a subordination request as a new credit decision. It looks at the size of the new first mortgage, the property value, and the full credit limit. Then it asks whether its line is still safe behind a larger lien.
Across files, three things drive the answer:
- Combined leverage after the refinance. A modest, low-leverage refinance is a more realistic request than a maximum-leverage cash-out.
- Credit profile. Consent often carries a minimum score.
- The holder’s own appetite. Policies differ by institution, and no public source lists them. Fees and processing steps vary as well, so treat any single quoted figure with caution.
The CFPB states plainly that you may need the HELOC lender’s approval to refinance the first mortgage, that the lender can refuse, and that a refusal may leave payoff as the only route. That one rule is the whole reason the bank list does not exist.
Run the Arithmetic Before You Apply
Take a property worth 100 units of value. The existing HELOC has a limit equal to 15% of that value, and the refinance would put a first mortgage at 55% of value. Combined, that is 70% CLTV, and the 15% counts whether you have drawn one dollar or all of it.
Now compare the same property if the line is paid off inside the refinance. The new first mortgage must cover the old balance plus the HELOC payoff, so it is larger, and the loan is typically classified as cash-out. You trade a two-lien stack for one lien and a different leverage test.
Run both versions before you ask anyone for consent. If the stacked version lands near the ceiling, the HELOC holder is more likely to hesitate, and a payoff structure may be the cleaner route. This arithmetic is the first thing a lender checks, so it belongs in your own file first.
Edge Cases Where the General Rule Bends
A zero balance does not remove the line. An open line with nothing drawn is still a recorded lien until it is formally closed. It needs subordination or a closure letter just like a drawn line.
A HELOC on a different property. That line is not a lien on the property being refinanced, so no subordination is needed there.
A HELOC as the only lien. A HELOC typically is a second lien only when a first mortgage exists. On a property owned free and clear, the line sits in first position, as bills.com notes.
Sequence matters. A HELOC opened behind an existing first mortgage needs that first lender’s consent under its loan documents. A HELOC opened first has to be subordinated when you later refinance. Opening a line just before a planned refinance creates a consent request you did not need.
A HELOC after an investor first lien. If the first lien is a DSCR loan, the answer sits in that loan’s documents, which must allow a junior lien. Read them before you open the line, not after.
Alternative-income borrowers. Bank-statement or similar documentation changes how income is proven. It does not change lien priority or who must consent.
Government-backed first mortgages. These follow their own refinance paths, but the HELOC holder still has to agree to subordinate.
What Changes for Investment Properties
Most of the mechanics above apply to any property. Investment property adds a title problem and a supply problem.
Supply. Fewer lenders write lines on rentals than on owner-occupied homes. Closing a line during a refinance can therefore mean losing it permanently. That makes the consent request worth more effort than it would be on a primary residence.
Title. Investment-property lines generally require title in an individual’s name or an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on the wholesale programs Lendmire places. A rental already deeded to an LLC needs a vesting change before a HELOC is possible, or it points toward a DSCR cash-out instead.
Network figures for investment lines. On an investment property, the ceiling is 70% CLTV, with a 700 minimum credit score and a maximum line of $500,000, subject to lender guidelines. These lines run a 5-year interest-only draw followed by a 25-year fully amortizing repayment, and pricing floats across both periods. At least 75% of the line is drawn at closing. Lines at or below $500,000 ordinarily use automated valuation, though a full appraisal can be requested.
Lendmire’s piece Best Investment Property HELOC Program When Refinancing a Mortgage With an Open HELOC covers that side in more detail.
Owner-Occupied Lines Have Different Ceilings
If the property is your primary residence or second home, the grid is wider, which is why a single “max CLTV” number is misleading. Keep each tier with its occupancy.
On a primary residence, the 90% CLTV ceiling exists only at a 720-or-better credit profile and only up to $500,000. At 700 and above, 85% CLTV is available up to $500,000. Lines of $500,000 to $750,000 are primary-residence only, cap at 75% CLTV, require a full appraisal, and call for 700 or better credit (720 on the longer-runway structure, a 5-year draw with a 25-year repayment).
On a second home, the ceiling is also 90% CLTV at 720 and above, up to $500,000. The credit floor is 640. Any higher CLTV figure you see quoted elsewhere reflects the broader market, not this network.
A line can sit in first or second lien position. A standalone first-lien line can help where the first mortgage is already paid off. These lines are placed only in 16 states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. That is narrower than Lendmire’s DSCR footprint of 41 markets, including Washington, D.C.
Lender Types and What to Ask Before Paying for an Appraisal
Screen by lender type, then by question. The right lender depends on your property, credit profile, leverage, and documentation.
The current HELOC holder. Ask whether it will subordinate to a new first mortgage of a stated size, what its CLTV limit is, whether a minimum credit score applies, and who handles requests. Ask for the subordination department’s contact, not just a branch.
The refinance lender. Ask whether it requires the HELOC to be closed, subordinated, or either. Ask whether paying the line off makes the loan cash-out under its rules, and what that does to the leverage ceiling.
A new junior lender. Ask whether it writes on your property type and title. Confirm it accepts your occupancy, since investment lines, second-home lines, and primary-residence lines carry different ceilings.
A broker. A broker that shops multiple wholesale lenders can match the file to a program before you spend money on valuations. It cannot force consent from your existing HELOC holder.
- Current first-mortgage payoff and the HELOC’s full credit limit
- Recent statements for both loans, and the HELOC agreement with draw-period dates
- Payoff letters, not just balances
- The subordination contact at the HELOC lender
- How the property is titled
- A written plan for what happens if consent is refused
The Process Step by Step
1. Inventory every lien. Pull the first-mortgage payoff, the HELOC’s limit, and a realistic value. Disclose the HELOC on day one.
2. Pick a path. Subordinate, pay off and close, or pay off and replace.
3. Request subordination early. The refinance lender or title company usually sends the request, and it is typically a condition of the new loan.
4. Let the HELOC holder underwrite it. Expect it to test combined leverage on the full limit.
5. Sign and record. The agreement is recorded with the county, usually alongside the new mortgage through the title company.
6. Confirm in writing afterward. Get written confirmation that the line was closed, left open, or subordinated as agreed.
Timing depends on how fast two lenders and a title company coordinate, and no reliable outside source gives a typical figure, so plan around the slowest party rather than a quoted number.
When Consent Is Refused
A refusal is a decision about that file at that moment, not a permanent verdict. The fallback options are limited, so choose deliberately.
- Pay the line off inside the refinance. The lender sees one clean first lien. Expect the cash-out classification.
- Pay it down first. A smaller line lowers combined leverage and may change the answer, but it needs a second request.
- Delay the refinance. If the first mortgage carries terms worth keeping, waiting can beat forced payoff.
- Move the equity access to a different structure. For a rental, a DSCR cash-out refinance can replace the line. On a standard rental, cash-out refinance tops out around 75% LTV across most of the network, with about 6 months of seasoning as the common expectation. On short-term-rental collateral, the cash-out ceiling is 70%. Most programs want a credit score near 660, with a 620 floor in parts of the network and 700 or better opening the strongest leverage tiers. Loan sizes run up to $3,000,000 on standard programs (smaller balances available through select lenders), and reserves commonly sit around 6 months of PITIA, though they vary by lender, leverage, loan size, and transaction type. LLC-titled borrowers are possible, subject to lender program eligibility.
DSCR compares rent to the monthly housing obligation. Clearing 1.00 is where select programs start, but it is not the same as positive cash flow, since repairs, vacancy, and management sit outside the ratio. A HELOC payment you keep carrying still comes out of your own cash flow, so weigh it yourself. Many DSCR loans carry prepayment terms, so check those before planning a later refinance.
Lendmire’s complete DSCR loans guide walks through how that alternative is structured. A different Lendmire article on refinancing the first mortgage with a HELOC already open covers the owner-occupied angle.
Common Misconceptions
The new lender can force the HELOC to subordinate. It cannot. It can ask, and the HELOC holder answers.
A zero balance means no problem. The open line is still a recorded lien.
Only the drawn balance counts. The full credit limit counts toward CLTV.
An earlier subordination carries over. It was written for the old first mortgage.
Paying the HELOC off is a rate-and-term deal. It typically makes the loan a cash-out refinance.
A DSCR HELOC is the same as a bank HELOC. The two are different products. A DSCR cash-out is a first-lien refinance that qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. A HELOC is a line that also looks at credit, debt-to-income, and combined leverage.
Frequently Asked Questions
Can I refinance my first mortgage and keep my HELOC open?
Sometimes. It works when the HELOC holder signs a subordination agreement agreeing to stay behind the new first mortgage. If it declines, the refinance lender will generally require the line to be paid off and closed.
Which banks will let me keep my HELOC through a refinance?
No reliable list exists, because the existing HELOC holder decides file by file. Its answer turns on combined leverage, your credit profile, and its own appetite. The most useful step is to ask your current HELOC holder directly before you pick a refinance lender.
Does paying off the HELOC in the refinance make it a cash-out loan?
Usually yes. Folding the line into the new first mortgage typically classifies the whole transaction as cash-out, even if no money reaches you. That can change the leverage ceiling and seasoning review, so confirm the classification with the refinance lender early.
Can I open a new HELOC after I refinance?
Often, but eligibility depends on occupancy and title. On an investment property, the network ceiling is 70% CLTV with a 700 minimum credit score, and the property must be titled to an individual or a revocable trust rather than an LLC. Fewer lenders write rental-property lines, which is why closing an existing one carries risk.
What if my HELOC is on a different property than the one I’m refinancing?
No subordination is needed, because that line is not a lien on the property being refinanced. The line can still matter for debt-to-income or exposure limits, so disclose it anyway.
