The Quick Read: When you refinance a first mortgage, the home equity line behind it does not disappear. It moves up to first position unless its lender signs a subordination agreement, which is a document that lets the new loan go first. Most new first-lien lenders will not close without that signature, so the line must be subordinated, paid off, or rolled into the new loan.
- The HELOC lender has to agree, and it can say no.
- The test is mostly combined leverage after the new loan, not your payment history.
- A no-cash-out refinance is easier to subordinate than a cash-out refinance.
- If consent fails, the usual exits are paying off the line or consolidating it into the new first.
- A DSCR first lien needs first position, so the line gets handled before closing.
Investors hit this wall more than they expect. You own a rental, you drew on a line for a rehab, and now a better first mortgage is on the table. The new lender wants first position. The old line holder holds a veto. This guide walks through how that plays out and what to do about it.
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
Subordination agreement: A signed document in which one lienholder agrees to rank behind another. Wikipedia’s entry on subordination agreements describes it as a way to give first-lien status to a lender who would otherwise sit second, with the approval of the party that would otherwise be first.
Resubordination: A fresh subordination request made when the HELOC already sits behind one first mortgage and a different first mortgage is replacing it. The new first lender gets a new review.
Senior and junior lien: The senior lien is paid first if the property is sold or foreclosed. The junior lien is paid from what is left.
CLTV (combined loan-to-value): All loans secured by the property, added together and divided by its value. For a line, lenders count either the full credit limit or only the drawn balance, depending on their rules.
Recording priority: The order in which liens are filed in the county records. Earlier filing usually means higher rank.
DSCR (debt service coverage ratio): A rental loan test that compares the property’s monthly rent to its monthly housing payment: principal, interest, taxes, insurance, and any association dues. Together these are called PITIA.
What Happens to Lien Order When You Refinance?
Refinancing pays off the old first mortgage, and the HELOC automatically steps into first position. Liens follow a first-in-time rule, so the oldest recorded lien ranks highest. Once the old first is gone, the line is the oldest lien left. The new loan would land behind it unless someone changes the order.
Here is the sequence on a typical investment rental:
1. You hold a first mortgage and a HELOC behind it.
2. The refinance closes and the old first is paid off.
3. The HELOC becomes the oldest recorded lien, so it is senior by default.
4. The new loan records afterward, so it would rank second.
5. A subordination agreement, recorded with the new mortgage, flips that order back.
| Stage | First position | Second position |
|---|---|---|
| Today | Old first mortgage | HELOC |
| Old first paid off | HELOC | (empty) |
| New loan, no agreement | HELOC | New loan |
| New loan, with agreement | New loan | HELOC |
Notice what subordination does not do. The line keeps its limit, its balance, and its repayment terms. Nothing is paid down or removed. Only the order of the claims changes. People often assume the agreement shrinks the HELOC, and it does not.
Why the New First Lender Won’t Sit in Second
A new first-lien lender prices and sizes its loan on the assumption that it gets paid first. Sitting behind an unplanned line changes that risk completely. Bills.com’s explainer on subordinating a HELOC says that without a subordination agreement, most refinance lenders will not close.
That matches what happens across the wholesale network Lendmire places files with. DSCR first-lien programs generally expect first position. A few lenders may look at an existing junior lien case by case, but the standard assumption is a clean first slot. Plan for that and you avoid a surprise at the closing table.
Who Decides, and What the HELOC Lender Checks
The HELOC lender decides, and it has no duty to say yes. The Consumer Financial Protection Bureau states that you may need your HELOC lender’s approval to refinance your first mortgage. It adds that the lender can refuse, and that you may then need to pay off the HELOC to refinance.
That makes this a three-party deal: you, the new first lender, and the line holder. A clean payment history helps. It does not guarantee a yes.
Here is what the line holder weighs:
- Combined leverage after the new first. This is the core test. The question is whether the new first plus the line still fits the lender’s limit against the property’s value.
- Full limit or drawn balance. Depending on the lender, the whole credit line may count as owed even if you have drawn little. The new first lender worries about the same thing, since the line could be drawn later.
- Size of the new loan. A no-cash-out refinance leaves senior debt about where it was. A cash-out refinance puts more debt ahead of the line, so the junior lender faces more risk.
- Credit and payment history on the line. Late payments make a yes harder.
- Property value. A weak or falling value squeezes the combined-leverage math.
For scale, consider how the network treats new investment-property lines. Those lines top out at 70% CLTV on an investment property, with a 700 minimum credit profile, a $500,000 maximum line, and a 5-year interest-only draw followed by a 25-year repayment. Each existing line holder sets its own limit for subordination. Still, the example shows how tight junior-lien leverage gets on rentals.
One practical fix many borrowers miss: if the test counts the full limit, lowering the limit can help. Ask the line holder to reduce or freeze the limit before the request goes in.
The Second-Position HELOC Subordination Rules, Step by Step
Here is how a request moves from start to finish.
1. Decide the path. You choose among paying off the line, folding it into the new loan, or asking for subordination. This article covers the third path, and the options table below compares all of them.
2. Tell the new first lender about the line up front. Disclose it on the application. A surprise lien found in the title search can stall a file.
3. Authorize the request. The new first lender or the title company usually contacts the HELOC servicer. You typically provide or authorize access to the line’s loan information, and a copy of the HELOC note is commonly requested.
4. The HELOC lender underwrites the request. It reviews the factors above and sends back an approval, a counteroffer, or a refusal.
5. Sign the agreement. Once approved, the line holder issues the subordination agreement for signature.
6. Title and recording. The title company folds the signed agreement into the closing package. It is recorded along with the new mortgage, which is what protects the new lender’s priority.
7. Draws on the line. The balance of a revolving line can rise until the line is frozen. Many new first lenders want a freeze or a fixed balance during the process.
Timing deserves a plan. Subordination adds a step that depends on a third party’s schedule. Submit the request early, before your loan terms are set to expire, so a slow junior lender does not run out your commitment window. Whether the HELOC sits with the same institution as the old first or a different one does not change the rule. A same-lender line may be easier, but it is not automatic.
Your Options Compared
Subordination is one of four paths. The right one depends on the size of the line, the leverage left after the refinance, and whether you want to keep the line open.
| Option | Fits when | Main risk | Line stays open? |
|---|---|---|---|
| Subordinate the line | No-cash-out refi, leverage fits | Lender can refuse | Yes |
| Pay off and close the line | Small balance, or refusal | You lose the credit access | No |
| Consolidate into new first | Cash-out refi covers both | Higher first-lien balance | No |
| Refinance only the second | First mortgage is worth keeping | Different terms on the junior loan | Depends |
The consolidation path deserves a closer look for rental owners. A DSCR cash-out refinance can pay off the old first and the HELOC in one new loan, and the new loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Across most of the network, cash-out refinances top out around 75% LTV on a standard rental, with about six months of ownership (seasoning) as the common expectation. The 75% cap applies to all the debt the new loan replaces, so the line’s balance eats into the cash you can pull. The complete DSCR loans guide walks through the other rules.
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. A stronger ratio generally opens better pricing and leverage.
Clearing 1.00 is also not the same as positive cash flow. Repairs, vacancy, management, utilities, and capital spending all sit outside the calculation, so size your reserves with those in mind.
If the HELOC Lender Says No
A refusal is not the end of the refinance. Work through these in order.
1. Ask what they would approve. Some lenders will agree if the new first is smaller, or if the balance on the line is lower. Ask for the actual limit they will accept.
2. Pay the line down, or reduce its limit. If the limit is what pushes combined leverage over the line, lowering it may change the answer. Freeze new draws while you do.
3. Consolidate into the new first. If the refinance is a cash-out and the numbers fit under the leverage cap, the new loan can retire the line directly. No agreement is needed because the line is gone.
4. Pay off and close the line. Use your own cash or another source. You lose the credit access, but the refinance can move forward.
5. Restructure or wait. If none of those fit, reconsider the size of the refinance or the timing. A smaller loan may clear leverage limits that a bigger one cannot.
The trade-off is access versus simplicity. Keeping the line preserves flexible capital, but it raises combined leverage and puts a third party in the middle of your closing. Closing the line removes the veto altogether.
Edge Cases Where the General Rule Breaks
A HELOC is not always second. Lien position depends on what is already recorded, not the product type. On a property with no first mortgage, Bills.com notes a HELOC can be the first lien. If you later want a new first mortgage on that property, the line must be paid off or subordinated just the same.
A tiny line against a large new first. When the balance is small, paying it off is often simpler than chasing a signature. The paperwork cost may exceed the benefit of keeping the line open.
Adding a HELOC behind an existing first is a different situation. Subordination comes up when the line already exists and a new first is coming. A new line added behind a first mortgage is governed by the first lender’s loan documents, including any covenant limiting additional liens.
Resubordination. If the line already sits behind one first and a different first is replacing it, the line holder reviews the request fresh. Approval on the old structure does not carry over.
Other junior liens. The same logic applies to a second mortgage that is not a HELOC. Any junior lien outranks the new loan unless its holder agrees to rank behind it.
An LLC in the picture. DSCR loans can close in the name of an LLC, subject to lender program eligibility. Home equity lines through the network cannot be held by an LLC, corporation, partnership, or irrevocable trust. If a property is already deeded to an LLC, it needs a vesting change before a line fits, or a DSCR cash-out refinance instead.
Eligibility limits on lines. Manufactured homes, co-ops, condotels, log homes, and mixed-use or agricultural-zoned properties are not eligible for those lines. On the DSCR side, manufactured homes, log homes, and barndominiums are not offered.
What the Investor Decision Looks Like in Practice
Many investors use a HELOC as short-term capital for a rehab and plan to refinance out of it. That sequence works when the exit is planned before the first draw. The lien question is simply part of the exit.
Say you own a rental with a line drawn for repairs and a new first mortgage lined up. Before applying, run through this checklist:
- Pull the line’s current balance, its limit, and its draw status.
- Ask the line holder whether it counts the limit or the balance, and whether it will freeze draws.
- Decide whether the refinance is no-cash-out or cash-out, since that shapes the junior lender’s risk.
- Estimate combined leverage with the new first included.
- Price the alternatives: subordinating, paying off, or consolidating into a DSCR cash-out refinance.
- Check how the property is titled, since that affects which products fit.
A line you are not touching can still block a refinance. That surprises many owners, because the balance may sit near zero while the lien stays recorded. The lien matters more than the usage.
Keep in mind that home equity lines through the network are available in Lendmire’s 16 full-service states only. That is narrower than the 41-market DSCR footprint, which includes Washington, D.C. 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.
Frequently Asked Questions
Can I keep my HELOC when I refinance my first mortgage?
Yes, if the HELOC lender signs a subordination agreement and the new first lender accepts the structure. Neither is automatic. If the line holder refuses, you may need to pay off the line, consolidate it into the new loan, or change the size of the refinance.
Is subordination automatic?
No. It is a request that the HELOC lender reviews and can decline. The line holder looks at combined leverage, the size of the new loan, your credit, and the property’s value. Treat it as an approval step, not a formality.
Does a zero balance on the line still matter?
Yes. An open line is still a recorded lien, and the new first lender worries about the amount that could be drawn. Some lenders count the full limit rather than the balance. Closing the line or reducing its limit before the request can solve the problem.
Do I need a subordination agreement if I consolidate the line into the new loan?
No. If the new loan pays off the HELOC at closing, the line is retired and nothing remains to reorder. The tradeoff is a larger first-lien balance, which has to fit under the new loan’s leverage cap.
Will my draws be frozen during the process?
Often, yes. Because a revolving balance can grow, a new first lender usually wants the balance fixed or the line frozen. Ask the line holder about its freeze procedure at the start so it does not delay the file.
