The Quick Read: No ranked list of providers can answer this, because subordination is a decision the line holder makes file by file. What you can control is the structure you choose, the leverage you carry, and the questions you ask before you open the line.
- A refinance that pays off the old first mortgage pushes an existing line into first position, so the new lender needs the line holder to sign a subordination agreement or the line must be closed.
- The line holder can agree, charge for it, or refuse. The new lender only asks.
- A DSCR HELOC (a line of credit on a rental, qualified on the property’s rent) is written either as a standalone second lien behind a first mortgage you keep or as a standalone first lien on a rental with no mortgage.
- Combined leverage counts the full credit limit, not the drawn balance.
- The best provider for you depends on your property, credit, leverage, and how the first mortgage is held.
Why Does Refinancing the First Mortgage Force the Question?
Lien priority follows recording order. Your first mortgage is first because it was recorded first, and a line recorded later sits behind it. When a refinance pays off the old first mortgage and releases it, the line becomes the oldest mortgage on record. Left alone, it would jump to first position.
No new lender will fund behind that. Lawyers.com notes that most lenders won’t refinance a first mortgage unless the second-lien holder signs a subordination agreement. It also notes that second-lien lenders don’t always agree to take the lower priority.
The agreement changes priority and nothing else. Your line keeps its limit, its draw rules, and its terms. The line holder simply agrees that the new first mortgage gets repaid first in a foreclosure. Wikipedia’s overview adds that the junior holder usually prefers to subordinate, since releasing and re-filing its own mortgage brings extra cost and priority problems.
Why You Won’t Find a Ranked List of Providers Here
Lendmire is a mortgage broker, not a lender, and it places DSCR HELOC files with wholesale lenders in its network. Naming a winner would mislead you. Whether a line holder will subordinate depends on your property, your credit, your combined leverage, and what the new first mortgage looks like.
So the useful question is how to pick a provider whose policy fits your plan. A broker that shops several wholesale lenders can match the scenario to a program, and the lenders that write this product vary in how they handle consent. The checklist further down gives you the questions that sort providers.
How Underwriting Treats Subordination, Step by Step
The line holder is asking one core question: is the line still safe behind the new first mortgage? Here is how that review typically runs.
1. Map the lien stack. Write down the first-mortgage payoff, the line’s full credit limit, and the property value. Combined loan-to-value (CLTV) is the first mortgage plus the whole line, divided by value.
2. Choose a path. You can subordinate and keep the line, pay off and close the line at the refinance, or roll everything into a new first lien. Rolling in needs no subordination, because one new loan replaces the whole stack.
3. Request the agreement. The refinance lender or title company asks the line holder, usually through a dedicated subordination desk. Treat it as a closing condition and ask early.
4. The line holder reviews. It compares the new first mortgage to the old one, looks at how much cash comes out, and recalculates combined leverage with the full limit counted. It also looks at how the line has been paid.
5. Sign and record. The agreement is recorded with the county, usually alongside the new mortgage through title.
An old agreement written for the previous first mortgage does not carry over. Each new first mortgage needs a fresh one. Expect these documents: recent statements for both loans, the title commitment, the agreement itself, and a payoff letter if the line is closing. Fees and turnaround vary by line holder, so ask for both in writing.
What a DSCR HELOC Looks Like Across the Network
A DSCR HELOC is a revolving line secured by a rental you keep. The rent qualifies it, so the lender does not calculate your personal income, subject to lender guidelines. Your LLC can stay on title, subject to program terms. It is never a line on your own home or a second home, and it is never a third lien.
The line is written either behind a first mortgage you keep or as the first lien on a rental with no mortgage, and it does not close alongside a purchase. Here are the structures at a glance. Every figure is a ceiling or floor on select programs, subject to underwriting.
| Factor | Second lien | First lien |
|---|---|---|
| When it applies | Behind a first you keep | Rental with no mortgage |
| Credit score | 720 or better | 700 or better |
| Leverage | Up to 70% CLTV | Up to 75% LTV at 740+ |
| Mid tier | None below 720 | 70% LTV at 700-739 |
| Line size | $50,000 to $500,000 | To $1,000,000 |
| Over $500,000 | Not offered | 65% LTV at 720+ |
The coverage test is a minimum 1.10x. Gross monthly rent is divided by a stress payment on the entire credit limit. Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. A lease must be in place, and a two-to-four-unit property may have at most one vacant unit. Whether the first-mortgage payment joins the coverage calculation on a second lien depends on the lender’s own method, so confirm on the file how it is treated.
Terms are a 5-year interest-only draw period, then a 25-year repayment period, with a 30-year maturity and a variable rate. At least 80% of the line is drawn at closing, and later draws are at least $5,000 each. No reserves are required.
For valuation, lines up to $400,000 use an automated valuation with a property inspection report, or a full interior appraisal. Larger lines take the full appraisal. Appraisal waivers are not accepted.
Seasoning has two clocks, and both are written into one rule: 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).
The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Exposure is capped at 5 loans or $2,500,000 per borrower with the program. Rural property, condotels, row homes, and leaseholds are outside it. The complete DSCR loans guide covers how property-rent-based lender review works more broadly.
Four Paths When the First Mortgage Gets Refinanced
The right path turns on how much leverage the new first mortgage consumes and how much you value the line.
| Path | What happens | Fits when |
|---|---|---|
| Subordinate | Line stays, priority drops | Line holder consents, leverage fits |
| Pay off and close | Line retired at closing | Holder refuses or leverage is tight |
| Roll into cash-out | One new first lien | You want one loan, not two |
| Skip the refinance | First stays, line stays | The first is worth keeping |
Picture a rental with a first mortgage at 45% of value and a line sized at 20% of value. Combined leverage is 65% CLTV, inside the 70% second-lien ceiling at 720 or better. Now suppose the refinance lifts the first to 55%. The same line pushes the stack to 75%. A line holder reviewing that stack may decline to consent, because the combined number sits above what the program writes on a new second lien. Whether any given holder consents is that holder’s call.
Because the full limit counts, a large unused line can crowd out cash on the refinance. Shrinking the limit before the refinance sometimes helps. A refinancing of the first can also be where a prepayment penalty on the existing first matters, which may favor keeping the first and adding a line.
Where the General Rule Breaks
These edge cases catch investors who assume subordination works the same everywhere.
- A zero balance does not remove the lien. An unused line stays recorded until it is formally closed, so it still needs closure or subordination.
- A line can be the first lien. On a rental with no mortgage, the line sits first. Subordination only arises when a new mortgage is placed later.
- A DSCR first mortgage may restrict additional liens. Its loan documents can limit a junior lien, and the loan may later be sold. Get the servicer’s position in writing before you open a line behind it. Some second-lien matrices also exclude subordinate financing behind many non-QM first mortgages.
- No third liens. If an existing second stays, a new line would be a third lien. The old line must be closed first.
- Seller, gap, or hard-money seconds. These lenders owe you no subordination, so plan to pay them off at the refinance.
- Keeping a second while taking cash out is generally treated as cash-out, with lower leverage caps than a rate-and-term refinance.
- Thin coverage. A variable-rate line payment can pull a thin DSCR first mortgage below 1.00x. Short-term rentals are hardest here. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.
- Declining-market flags. A declining-market designation lowers the program ceiling by 5 points.

Questions to Ask Any Provider Before You Open the Line
Use these to sort providers. Their answers matter more than their marketing.
1. Do you subordinate to a refinanced first mortgage, and is that always, case by case, or never?
2. What do you review: loan amount, cash out, combined leverage, payment history?
3. Do you charge for the agreement, and what does closing the line early cost?
4. Does the line count its full limit toward combined leverage?
5. Will you work with an investor-owned or non-QM first mortgage?
6. Can the line stay in my LLC through the refinance?
7. What does the first-mortgage servicer say about adding a second lien?
Ask for answers in writing. A provider that cannot describe its policy before closing probably has not set one.
Open the Line Before or After the Refinance?
If a refinance is coming, ask about subordination before you open any line. A line opened just before a planned refinance creates a consent request you did not need.
If the refinance is a year or more out, a line can fund the next purchase. You then refinance out of it once the rent seasons. The risk is the variable rate squeezing cash flow while you wait.
Key Terms Defined
Subordination agreement: a signed document in which a lienholder agrees to rank behind another lender’s mortgage.
Lien position: the order in which lenders are repaid from a sale or foreclosure, set by recording order.
CLTV: combined loan-to-value, meaning all mortgages plus the full line limit, divided by property value.
DSCR HELOC: a revolving line on a rental, qualified on the property’s rent instead of your personal income.
Draw period: the stretch when you can borrow from the line, followed by repayment.
Frequently Asked Questions
Is subordination automatic when I refinance?
No. The line holder decides, and it can consent, charge for it, or decline. If it declines, you either pay off and close the line or give up the refinance. Ask early so you have time to choose.
Does subordination change my line’s terms?
No. It changes priority only. The limit, the variable rate, and the draw and repayment periods stay as written. The line holder is simply agreeing to sit behind the new first mortgage.
What if I want a line behind a DSCR first mortgage?
Start with the first loan’s documents, which may limit additional liens. A DSCR HELOC also requires a 720 score on a second lien and a 1.10x stress test on the full limit. Confirm on the file how the lender treats the first-mortgage payment. Exact terms depend on lender and investor guidelines, credit profile, reserves, and property review.
How does seasoning work on a DSCR HELOC?
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).
Can my LLC hold the property and the line?
Yes, on an investment property. The members sign as guarantors, subject to program terms. A title holder who is not a borrower signs an acknowledgment and the security instrument.
