The Quick Read: The best program for your file is the one that lets the new loan pay off the existing second mortgage and still leaves room under the leverage cap. A cash-out refinance puts a new first lien on the property, so the second has to be paid off or subordinated at closing.
- Cash-out leverage tops out at 75% LTV on a standard rental across most of the network. Short-term-rental collateral sits lower.
- The new loan has to cover the first payoff, the second payoff, and closing costs. Whatever is left is your cash.
- Rent has to cover the larger payment. Select programs start at 1.00 coverage.
- Keeping the second means the junior holder must agree to sit behind the new loan, and it can refuse.
- The right fit depends on your equity, credit, rent, and property type, which is why a broker shops several wholesale lenders. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
You already have a second lien on a rental, and you want cash out. That one fact changes the order of operations. It does not change the product. This guide walks through how underwriting treats the second, the structures that exist, and where the general rule breaks.

Key Terms Defined
Cash-out refinance: A new, larger first mortgage that pays off the old loan and returns the leftover equity to you as cash.
First lien and junior lien: The first lien is paid first if the property is sold or foreclosed. A junior lien, such as a second mortgage or HELOC, is paid after it.
HELOC: A home equity line of credit, a revolving second loan secured by the property.
Subordination agreement: A written deal in which the second-lien holder agrees to stay behind the new first mortgage.
Combined loan-to-value (CLTV): All liens on the property added together, divided by its value.
DSCR: The debt service coverage ratio. You divide monthly rent by the full monthly payment: principal, interest, taxes, insurance, and any HOA dues.
Seasoning: The waiting period between buying a property and refinancing it. Across most of the network, about six months of ownership is the common expectation for a cash-out.
What Happens to a Second Mortgage in a Cash-Out Refinance?
A new lender will not close behind another lender. The existing second has to be paid off at closing or formally agree to stay in second position. Those are the only two clean paths, and the first is far more common on DSCR cash-outs.
Here is why. When the new loan pays off the old first, that old lien disappears from the record. The second is suddenly the oldest lien on title, which puts it in first position. Wikipedia’s entry on subordination agreements states the consequence plainly: if the second-mortgage holder will not subordinate, the new lender will not refinance the first.
The CFPB’s guidance on HELOCs and refinancing points the same direction. Once you have a HELOC, you may need that lender’s approval to refinance your first mortgage. The HELOC lender can refuse. If it does, you may need to pay off the line to refinance. That page is general consumer guidance, not a DSCR rule, but the lien logic is the same.
So the choice looks like this.
| Path | What it means | Main risk |
|---|---|---|
| Pay off the second | New loan retires both liens | Shrinks your net cash |
| Subordinate the second | Second stays, sits behind new first | Junior holder can refuse |
| Skip the refinance | Keep first, use a second lien instead | Different product, different cost |
How Underwriting Treats the Second, Step by Step
Underwriting a cash-out with a second on title runs in a set order. Knowing it helps you see where a file gets stuck.
Step 1: Title and lien search. Title work finds every lien: HELOCs, closed-end seconds, private seconds, and any mechanics’ liens. A HELOC with a zero balance still has a lien. The line must be closed and the lien released in writing.
Step 2: Payoff statements. The first mortgage needs a payoff with daily interest. The second needs its own written payoff, because a HELOC balance moves with draws and interest. Ask for closure instructions at the same time.
Step 3: Pick the path. If the second is being paid off, there is nothing to subordinate. If it stays, the new lender requests a subordination agreement. The junior holder reviews that request like a fresh credit decision. It looks at the new first mortgage, the property value, and the full line, and its own limits on combined leverage may decide the outcome.
Step 4: The DSCR test. The lender checks whether rent covers the payment. If a second stays in place, it adds a payment, and rent has to carry both. If the second is paid off inside the new loan, the first gets bigger and the payment rises that way instead. Either way, coverage drops compared with the old setup. Select programs start at 1.00 coverage, and stronger ratios open better pricing and leverage.
Step 5: Size the proceeds. Net cash equals the new loan, minus the first payoff, minus the second payoff, minus closing costs and prepaids, minus any prepayment charge on the old note. On thin equity, that number can land at zero.
Step 6: Close and record. The new first mortgage is recorded. Either the second is released, or the subordination agreement is recorded with it.
How Much Does the Second Shrink Your Cash-Out Check?
It shrinks it dollar for dollar. The 75% LTV ceiling is a limit on all the new debt, so everything the new loan must pay off comes out of the same pool before you see a cent. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Run the numbers on a generic rental valued at 100 units. At the 75% cash-out ceiling, the new loan can reach 75 units. Suppose the old first is 50 units and the second is 15 units. The two payoffs total 65 units. Closing costs and prepaids come next, say 3 units. That leaves about 7 units of cash (75 minus 65 minus 3). With no second on title, the same property would have returned about 22 units (75 minus 50 minus 3). Every figure here varies by lender and program, since guidelines, property type, leverage, and credit profile all apply.
Now picture a property where the first is 60 units and the second is 14 units. The payoffs total 74 units, and costs push past the 75-unit ceiling. This file becomes a payoff-only refinance with no cash back, and you may have to bring cash to close. That is the thin-equity case.
These are generic units, not market figures. Your lender will size the real number from the appraisal and payoff letters. This is also where the 75% cap matters most. A rate-and-term refinance, which returns no cash, carries a higher ceiling of 85%. But a refinance that retires a non-purchase-money second is often treated as cash-out, even if no money comes back to you. Programs differ on this, so confirm the classification before you plan around the higher tier.
Should You Pay Off the Second or Keep It?
Pay it off when the equity is there and you want a predictable closing. Keep it only when the junior holder is likely to cooperate and you want a smaller new first mortgage.
Paying off the second inside the new loan. Only one lien remains after closing, and you pay it off once, when you later sell or refinance. The cost is a larger first mortgage, a higher payment, and lower rent coverage. It is also the route you control. Nobody outside the lender and title company has to say yes.
Keeping the second with subordination. The new first loan is smaller, so the first payment is lower. But the second still has a payment, and rent has to carry both. You also depend on a third party. That junior holder is not required to subordinate. It is less likely to agree when total mortgage debt is close to the home’s value, and a cash-out raises the first balance, which makes the cushion thinner. Subordination is a formality only when equity is ample.
Paying the second down first. This needs your own cash. It can pull the combined leverage into range, but it is a different decision than a refinance.
If your closing needs certainty, paying the second off in the new loan is the more predictable route.
What Makes a Program the Best Fit for This File?
There is no single best program in the abstract. The best program for your situation is the one whose numbers fit your property, your equity, and your credit. Four things decide it.
1. Leverage ceiling versus your payoff stack. Across most of the network, cash-out refinances top out around 75% LTV on standard rentals. Short-term-rental cash-outs sit at 70%. Add up both payoffs and costs against that ceiling first.
2. Rent coverage of the new payment. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger coverage opens better pricing and leverage.
3. Credit. A 620 floor exists in parts of the network. Most programs want around 660. A score of 700 or higher unlocks the strongest leverage tiers.
4. How the lender classifies the second payoff. Some programs treat it as cash-out, which triggers cash-out leverage and credit tiers. This varies, so it is worth asking before you apply.
Loan size, reserves, and property type matter too. Standard programs run up to $3,000,000. Reserves commonly run about six months of PITIA, which is principal, interest, taxes, insurance, and association dues, and they step up to about nine months above $1,500,000. Reserves vary by lender, leverage, and transaction type.
A broker earns its place here. Each wholesale lender sets its own overlays on cash-out classification, seasoning, and how a junior lien is handled. The lenders that write your file depend on your scenario, and a broker matches the scenario to the program instead of sending you to one door.
Clearing the coverage test is not the same as positive cash flow. The calculation compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside it.
DSCR vs. conventional financing
There are two common ways to finance an investment property, and they qualify you differently — here’s how investors weigh them.
Why investors choose it
- Qualifies on the property’s rental income — no personal tax returns, W-2s, or pay stubs needed to document income.
- No personal debt-to-income ceiling to clear, so existing mortgages and obligations don’t cap your borrowing the same way.
- Can be closed in an LLC, keeping the property inside a business entity.
- Built for scaling — not held to the limit on number of financed properties that conventional financing applies.
- Underwriting centers on the deal: generally qualifies when the rent covers the payment, a 1.00x coverage ratio being a common baseline (confirmed in underwriting).
- Designed specifically for investment property, including long-term and, where the program allows, short-term rentals.
Where it’s strong
- Often the lowest ongoing financing cost for a buyer who fully qualifies on personal income — a fit for a first property or a cost-first purchase.
Trade-offs for investors
- Requires full personal income documentation and must fit within a debt-to-income limit — salary, existing debts, and other mortgages all count.
- Typically held in your personal name rather than a business entity.
- Caps how many financed properties you can carry, which can become a ceiling as a portfolio grows.
- Evaluates you as a borrower as much as the property, which usually means more paperwork.
How investors usually choose: a first or single property often optimizes for the lowest financing cost; portfolio builders often optimize for leverage, vesting in an LLC, and scaling past conventional caps. The right answer depends on your goals, the property, and current guidelines — both paths run through select lenders in Lendmire’s wholesale network, with eligibility and terms confirmed in underwriting.
Where the General Rule Breaks
These are the edge cases where a standard cash-out plan runs into trouble.
The junior holder refuses. The result is a forced payoff or a dead deal. The practical fix is to fold the second into the cash-out, if equity allows.
A second used to buy the property. A loan taken to purchase the property can be treated differently from a later equity draw. This varies by program, so it needs a check up front.
Recent HELOC draws. A line drawn heavily just before the refinance can change how the second is classified. Opening a HELOC shortly before a planned refinance also creates a subordination request you may never have needed.
Prepayment charges on the old first. DSCR loans often carry prepayment penalties in the early years, which discourages refinancing out of one. That charge comes straight out of your net proceeds.
A cheap existing first. A cash-out reprices the entire payoff balance, not just the new cash. If your current first is the best part of your debt, compare the blended cost of keeping it and adding a second against one full replacement loan.
A second behind an existing DSCR first. The documents on that first loan may restrict added liens. Read them before you record anything.
LLC title and a personal line. A HELOC taken in your personal name while the property sits in an LLC can complicate title and payoff. Loans to LLC-titled borrowers are available subject to lender program eligibility.
Ineligible property types. Manufactured homes, log homes, and barndominiums are not offered in the network’s DSCR programs, regardless of how much equity they hold.
Is a DSCR Second Mortgage a Real Alternative?
Sometimes, but it is a narrower market. A DSCR cash-out replaces the first. A second lien leaves the first alone. They are different structures, not two versions of one loan.
Investors sometimes ask about a rent-based second that sits behind an existing first. That route keeps a cheap first mortgage intact, which is its main appeal. The tradeoffs are a smaller pool of lenders and different pricing and leverage. If your current first is a keeper, it deserves a side-by-side look. If the first is average, one clean replacement loan is usually simpler. Lendmire’s piece Best Super Jumbo DSCR Cash-Out Refinance Program to Pay Off a Second Mortgage covers the larger-balance version of this problem.
What Should You Prepare Before You Apply?
A clean file moves through lien search and payoff without surprises. Gather these before you talk to a broker.
- Current statements for the first mortgage and every junior lien
- Written confirmation of how you want the HELOC handled, including closure
- The lease or rent history for the property
- Proof of ownership date, since seasoning runs from recording
- Insurance and entity documents if the property is in an LLC
- Evidence of reserves
Also ask your broker three things. How does this program classify a payoff of my second? What leverage tier applies if it counts as cash-out? Will the lender require subordination, or a payoff and closure?
Lending guidelines change, and each file is underwritten individually. Nothing here is a commitment to lend. For a fuller picture of how these loans work, see the complete DSCR loans guide.
Frequently Asked Questions
Can I do a DSCR cash-out refinance if I already have a HELOC on the rental?
Yes, but the HELOC has to be handled at closing. The usual route is paying it off from the new loan and closing the line. The alternative is a subordination agreement, which the HELOC lender can refuse. Either way, the new lender will want first position.
Does paying off my second count as cash-out even if I get no money back?
Often, yes. Many programs treat the payoff of a non-purchase-money second as cash-out, so the 75% cash-out ceiling and cash-out credit tiers apply.
What happens if the second-lien holder refuses to subordinate?
You pay the second off, either inside the new loan or with your own cash beforehand, or the refinance does not close. The junior holder has no obligation to cooperate, and refusal is more likely when combined debt is close to the property’s value.
How does a second mortgage affect my DSCR?
It raises the debt that rent has to cover. If the second stays, its payment is added to the new first. If it is paid off in the loan, the first grows instead. Either way, coverage falls compared with your old setup. Select programs start at 1.00, and a separate select-lender path goes below 1.00 with leverage and terms adjusted.
Will a thin-equity property return any cash?
Not necessarily. The new loan must first cover both payoffs and closing costs under the leverage cap. If those exceed the cap, the deal turns into a payoff-only refinance, and you may need cash to close.
