The Quick Read: A DSCR HELOC that stays behind a new first mortgage has to pass two separate tests: the rent must cover the line under a stress test, and the line lender must agree in writing to sit in second position. The first test is math, and the second is a consent decision that no formula can force.
- The rent must reach at least 1.10x on a stress payment over the entire credit limit, not just the drawn balance.
- A second lien reaches up to 70% CLTV at a 720 score or better, on lines of $50,000 to $500,000, subject to underwriting.
- The junior lender decides whether to subordinate. The new first-mortgage lender can only ask.
- Subordination changes lien priority only. It does not change the line’s terms or payments.
- If the junior lender says no, the usual fix is paying the line off at the refinance closing.
You own a rental, you have a line of credit against it, and you want to refinance the first mortgage. The refinance lender will not close unless your line steps back. This guide covers what that takes, what the underwriting looks at, and what to do when the answer is no.
Why a Refinance Forces the Question
Liens rank by recording order. Mortgage liens follow a “first in time, first in right” rule, so the first mortgage outranks a later second, as legal-education publishers explain. Priority matters in foreclosure, because the first lien gets paid first.
A refinance reshuffles that order. The old first mortgage gets paid off and released. Your line, still on title, moves up to first position. The new loan would land behind it.
No refinance lender wants that. Wikipedia’s entry on subordination agreements notes that a new lender will not refinance the first mortgage if the second-mortgage holder refuses to subordinate. A subordination agreement fixes this. It puts the new loan in first position and sends the existing line back to second.
Here is the before and after:
| Stage | First position | Second position |
|---|---|---|
| Before refinance | Old first mortgage | Your line |
| Old first paid off, no agreement | Your line | Nothing |
| After refinance with agreement | New first mortgage | Your line |
Subordination is not automatic. Without a signed agreement, the line simply moves up.
Key Terms Defined
Subordination agreement: a signed document in which a lienholder agrees to rank behind another lender’s loan.
Lien priority: the order in which lenders get paid from a property if it is sold in default.
CLTV (combined loan-to-value): all loans against the property, first mortgage plus the line, divided by the property’s value.
Resubordination: the same agreement, used when a line already behind one first mortgage must now sit behind a different one.
Stress payment: a fully amortizing payment calculated on the whole credit limit at the start rate plus 2 percentage points, used only to test qualification.
DSCR (debt service coverage ratio): gross monthly rent divided by the qualifying payment.
What Is a DSCR HELOC, and Where Does It Sit?
A DSCR HELOC is a revolving line of credit on a non-owner-occupied rental. It is written as a standalone second lien behind a first mortgage you keep, or as a standalone first lien on a rental with no mortgage. It is never a third lien. It is never written on your own home or a second home.
The rent qualifies the line. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. There is no traditional personal-income documentation: no W-2s, pay stubs or personal income calculations. The lease, the credit report and the valuation are all documented. The LLC can stay on title, with the members signing as guarantors. DSCR loans are designed for non-owner-occupied investment properties, and because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage.
A line can also be the first lien. Bills.com notes that a HELOC can sit in first position when no mortgage exists. Subordination only comes up later, if a new mortgage goes on the property.

The Two Tests
Across the wholesale network Lendmire works with, this is how the file splits.
Test one: the coverage math. Rent used for lender review is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. The qualifying payment is principal and interest on the entire credit limit at the stress rate. Taxes and insurance are not part of it. Divide rent by that payment, and the result must reach 1.10x, subject to underwriting.
Here is the catch for a second lien. Confirm on the file how the lender treats the first-mortgage payment in that coverage calculation. Do not assume it drops out, and do not assume it counts. The lender’s own calculation governs.
Test two: the consent decision. The junior lender reviews the new first-mortgage amount, current value and combined exposure. Bills.com says the new lender asks the line lender to sign the agreement. The junior lender then decides whether the equity covers both loans if a foreclosure happens. Equity alone never qualifies a file, but thin equity gets a no fast.
What the Requirements Look Like
These are typical ceilings and floors on select programs. They are subject to underwriting, and the lender’s own calculation governs.
| Item | Second lien | First lien |
|---|---|---|
| Leverage | Up to 70% CLTV at 720+ | 75% LTV at 740+; 70% at 700-739 |
| Line size | $50,000 to $500,000 | Up to $500,000; larger lines to $1,000,000 at 65% LTV |
| Credit floor | 720 | 700 |
| Coverage | At least 1.10x on stress payment | Same |
Larger first-lien lines above $500,000 run at a 65% LTV ceiling. Two more points apply to the combined leverage. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
- A second lien never goes above 70% CLTV, and the test uses the full credit limit, not the drawn amount.
- Some markets are flagged as declining, which lowers the ceiling by 5 points.
Terms are the same either way. The draw period is 5 years, interest-only on the drawn balance. Then a 25-year repayment period follows, with a 30-year maturity. The rate is variable. At least 80% of the line is drawn at closing, and later draws are at least $5,000 each.
The file also needs a valuation. Lines to $400,000 use an automated valuation with a property inspection report, or a full interior appraisal. Larger lines take a full interior appraisal. Appraisal waivers are not accepted.
A rental bought or refinanced inside the last 6 months is not eligible (that clock runs from the last note date to the new note date), and the owner must have held title for 6 months (settlement date to note date). Mortgage history needs no 30-day late in the last 12 months. Exposure tops out at 5 loans or $2,500,000 per borrower with the program.
Several property types fall outside the lane: rural-designated property, condotels, row homes and leaseholds.
Subordinate, Pay Off, or Roll It In?
You have three routes. Which one fits depends on the equity, the line lender, and whether you want to keep the line.
| Route | Who must agree | Main risk | Effect on the line |
|---|---|---|---|
| Subordinate | Junior lender | Refusal or stall | Line stays open |
| Pay off and close | Nobody | Need cash or proceeds | Line ends |
| Cash-out refinance | New lender | Reprices all debt | Line paid off |
Paying off the line is the usual plan on a DSCR refinance. If the proceeds pay the line in full and close it, no subordination is needed. A cash-out refinance pays off the old first mortgage and the old line with one new first mortgage.
The tradeoff is real. A cash-out refinance reprices the entire payoff balance. A second lien leaves your first mortgage alone. If your existing first mortgage carries terms you like, keeping it and adding a line may be the stronger play. If you were refinancing anyway, rolling everything into one loan can be cleaner. This is a genuine toss-up that depends on the numbers.
The Subordination Process, Step by Step
1. Inventory the liens. Write down the first-mortgage payoff, the line’s full credit limit, and the property value.
2. Ask early. The new lender requests subordination from the line lender. Starting at the beginning of the process beats waiting until clear-to-close.
3. The junior lender underwrites the request. It looks at the new first-mortgage amount, current value and combined exposure.
4. Sign and route. The agreement goes to the title company or escrow officer under the closing instructions.
5. Record. It is recorded alongside the new mortgage.
6. Close. The new first lien records in first position, and the line’s own terms stay the same.
Bills.com confirms subordination concerns repayment priority in a foreclosure or default and does not change your regular monthly payments. Corporate Finance Institute describes it as a narrow form of intercreditor agreement focused on the priority of creditors’ claims.

| Title company | Routes and records |
When the Answer Is No
The junior lender holds a veto. Many lenders want a record of on-time payments before they agree, and a line opened shortly before a planned refinance creates a subordination request you did not need. Not ideal.
If the lender refuses, you have a short list:
- Pay the line off and close it at the refinance closing.
- Use a larger new first mortgage to pay off both liens.
- Skip the refinance and keep the existing structure.
Before assuming the line stays open at all, read the line agreement for freeze or acceleration language. Some agreements let the lender freeze or call the line when a new lien appears.
If several lenders are involved, all of them must agree. And an older subordination was written for the old first mortgage, so it usually does not carry over to a new one. That is where resubordination comes in.
Edge Cases Where the Usual Rule Breaks
Seller, gap or hard-money seconds. A seller or gap second owes you no subordination at all. Plan to pay it off at the exit closing.
DSCR first, then a line behind it. This works only if the first lender’s documents allow it. Some second-lien lenders will not sit behind a non-QM first, and published second-lien matrices often exclude subordinate financing behind most non-QM firsts.
A zero balance. The line’s credit limit is still tested, and the open line is still a lien until it is closed. Do not assume a zero balance clears the way.
LLC title. The LLC can hold title, subject to program terms. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument.
Your own home. A line on a primary residence is a different, owner-occupied product. This program is written only on non-owner-occupied rentals.
A line already behind another first. Resubordination applies here. The same agreement, the same consent decision.
Files like these can stall on the line lender’s response time, which nobody controls. Experienced brokers ask for consent before the appraisal is ordered, not after.
Practical Takeaways
Count your leverage first. Add the new first mortgage and the full credit limit, then divide by value. If that lands above 70% on a second lien, subordination is a long shot and payoff is the cleaner route.
Then check the rent. A rental whose rent clears the stress test comfortably, with a lease in place and no more than 1 vacant unit in a two-to-four-unit building, gives the file a stronger footing. 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.
This program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Lendmire is a broker that arranges the line through a wholesale lender. Every file is underwritten individually, and nothing here is a commitment to lend.

Frequently Asked Questions
Does subordination change my HELOC payment or terms?
No. Subordination changes priority only. Your draw period, repayment period and variable rate stay as written, and the payment does not change because of the agreement.
Who asks for the subordination agreement?
The new first-mortgage lender requests it, usually after the refinance has an underwritten approval. The line lender then decides. The new lender can ask, but it cannot force the answer.
Does the line’s full limit count, or just what I have drawn?
The full limit counts. The junior lender tests combined leverage using the entire credit limit, and the DSCR stress payment is also calculated on the whole line.
What if I would rather close the line than subordinate it?
If the refinance proceeds pay the line off and close it, no agreement is needed. That is the usual plan on a DSCR refinance. Ask for a payoff letter and confirm the lien release records.
Can a rental I just bought get this line?
Two six-month clocks apply: the line is not available on a rental bought or refinanced in the last 6 months (last note date to new note date), and title must have been held for 6 months (settlement date to note date). Qualification remains subject to lender guidelines.
