The Quick Read: On a standard rental, a cash-out refinance typically lends up to about 75% of appraised value across all liens combined, so an existing second lien either gets paid off inside the new first mortgage or stays in place behind it, and either way it uses up part of that 75% before cash reaches the owner. The cap applies to total debt, not to the new first loan alone.
- Short-term-rental collateral is capped lower, at 70% on a cash-out.
- The choice between paying the second off and keeping it changes the payment structure and who has to consent, not the cash before costs.
- Rent must cover the larger obligation. Many select programs start at a 1.00 coverage floor, and stronger ratios open better terms.
- Seasoning of about 6 months, a credit score near 660 or better, and reserves of about 6 months of PITIA also shape the outcome.
- Clearing the coverage test does not mean the property cash-flows. Repairs, vacancy, and management sit outside the calculation.
What Does “Lends With a Second Lien” Actually Mean?
A second lien is a separate loan recorded behind the first mortgage on the same property. A cash-out refinance replaces the first mortgage with a larger one and pays the difference to the owner. When both exist, the new lender has to decide what happens to the junior loan, because it cannot let that loan sit ahead of its own.

A common first question is how much the new first mortgage can be. The better question is how much total debt the property can carry, and what is left after every existing lien is accounted for.
The sizing logic runs in plain steps:
1. Take the appraised value and multiply it by the leverage cap. On a standard rental cash-out across most of Lendmire’s wholesale network, that cap is about 75%.
2. Subtract every lien that will remain or be paid off: the old first and the second.
3. What is left is the room for cash, before closing costs.
Lendmire’s complete DSCR loans guide covers the loan type itself.
Three Ways a Second Lien Can Fit Into the Deal
An investor with a second lien has three realistic paths. Each one changes the paperwork, the payment, and the consent needed from other parties.
| Path | What happens to the second | Main catch |
|---|---|---|
| Pay it off in the new loan | Retired at closing | Whole balance reprices |
| Keep it and subordinate | Stays, sits behind new first | Second lender must sign |
| Skip the refinance | Handled on its own | No cash-out from this loan |
Paying it off inside the new loan. The new first mortgage carries both old balances. The 75% cap applies to that one larger loan. The result is a single lien and a single payment, with no later consent needed from a junior lender.
Keeping it through subordination. A subordination agreement is the document that lets the new first mortgage take first position while the old second stays junior. The new lender counts the first and second together against its cap. If the second is a revolving line, many lenders count the full credit limit rather than only the drawn balance, so check how the program treats it.
Skipping the refinance. Adding or keeping a junior loan without touching the first is a different product from a cash-out refinance. Its terms depend on the junior lender and on whether the existing first mortgage restricts junior liens.
How the Numbers Work: A Percentage Walkthrough
Percentages of value show the logic without dollar figures. These are modeled inputs, not market data.
Assume the existing first mortgage equals 50% of appraised value. Assume the second lien equals 15%. Combined debt is 65%. The cap is 75%.
| Step | Pay off second | Keep second |
|---|---|---|
| New first mortgage | Up to 75% | Up to 60% |
| Old first payoff | 50% | 50% |
| Second lien | Paid inside loan | 15% stays |
The cash before costs is the same in both columns. In the first, the new first is 75% and pays off 65 points of existing debt. In the second, the new first is capped at 60% because the second already uses 15 points of the 75% ceiling, and it pays off the 50-point first. Either way, 10 points of value are left.
Keeping a second lien therefore does not let you borrow more in total. The cap sits on the stack, and the stack is the same size.
Closing costs come out of that 10 points. A lower appraisal also shrinks it. A drop in appraised value cuts the allowed total debt and can push the room toward zero.
How Does Underwriting Treat the Second Lien, Step by Step?
Underwriting follows a fixed order. Knowing the order tells you where a deal can stall.
Step 1: Title search and payoff statements. These show every recorded lien: the first, any home equity line, and any private or hard-money second. The lender sizes the loan against total liens, so a lien you forgot about still counts.
Step 2: Appraisal. DSCR files use a full appraisal with a rent schedule. The common forms are Form 1004 for single-family, Form 1025 for 2-4 units, and Form 1007 for the rent schedule. Appraised value drives every leverage test, and the appraiser’s market rent drives the coverage test. Scotsman Guide’s trade coverage of DSCR lending makes the same point: the lender looks at the property, with rent coming from an appraiser’s rental survey. That article is a few years old, so treat it as background on the structure and not as current program detail.
Step 3: Classifying the transaction. A second lien that was not used to buy the property generally pushes the refinance into cash-out territory, even when no cash comes back. Paying off a junior loan with no cash to the owner often still prices and sizes as a cash-out, so plan around the 75% cap and not a higher rate-and-term tier. The exact treatment is program-specific.
Step 4: Deciding what happens to the second. The lender picks one of the three paths above, or the borrower does, based on the second lender’s willingness to cooperate.
Step 5: The coverage test. Rent used for lender review is divided by the full monthly obligation: principal, interest, taxes, insurance, and any association dues. That is PITIA. If the second stays, many programs also count its payment, and some do not, so ask which treatment applies.
Step 6: Clearing title and recording. The new first records ahead of any subordinated second. Seasoning is measured from title recording, and about 6 months of ownership is the common expectation for cash-out.
What Happens to Rent Coverage When Debt Stacks?
Every point of extra debt increases the monthly obligation, so coverage tightens as you pull cash. The increase is less than proportional because taxes and insurance do not change when the balance grows. The principal and interest portion does.
Run the numbers on a modeled file. Suppose a rental covers its existing obligation at about 1.40x. If the new obligation comes out 25% higher, coverage lands near 1.12x. That clears a 1.00 floor with some room, but it leaves less cushion for a rent dip.
| Structure | Typical coverage effect |
|---|---|
| Pay second off in new loan | One larger payment tested once |
| Keep second, subordinated | First and second may both be counted |
| Larger cash-out amount | Coverage moves toward the floor |
| Lower leverage chosen | More coverage cushion |
A separate select-lender path takes coverage below 1.00 with leverage and terms adjusted, so a file that lands under the line is not automatically dead. It does mean a different conversation.
Clearing the test is not the same as positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses are all outside the calculation. A file can pass at 1.15x and still lose money in a bad year.
Which Limit Binds First?
Several limits apply at once, and the tightest one sets the loan amount. A strong credit score does not override a rent shortfall, and plenty of equity does not override a reserves rule.
| Limit | Typical range | Binds when |
|---|---|---|
| Leverage cap | About 75% on standard rentals | Total liens are high |
| Short-term rental cap | 70% on a cash-out | Collateral is an STR |
| Loan size | Up to $3,000,000 standard | Value is very high |
| Credit tier | 620 floor; about 660 common; 700+ for top tiers | Score is near a tier line |
| Reserves | About 6 months PITIA; about 9 above $1,500,000 | Liquid assets are thin |
| Rent coverage | 1.00 where many programs start | New payment is large |
Above $2,500,000, the network generally holds to 30-year fixed structures. Extended 40-year terms and interest-only periods exist through select lenders for smaller balances, and ARM structures are available for investors who want them. These are options, not defaults, and terms vary by lender and file.
Reserves deserve a note. They vary by lender, leverage, loan size, and transaction type. Conservative rate-and-term files at modest leverage under $1,500,000 can see them waived. Ask whether cash proceeds can count toward reserves, because that varies by lender.
A larger down payment on a purchase lowers the payment and can lift coverage. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
Where the General Rule Breaks
The 75% sizing rule is a good map. These are the places where it fails.
The second lender refuses to subordinate. A second-lien holder is not required to cooperate. The CFPB’s guidance on home equity lines and refinancing says a borrower may need that lender’s approval, that the lender can refuse, and that the borrower may then have to pay the line off to refinance. The usual fallback is the single larger first-lien cash-out described above.
An old subordination agreement. An agreement written for the old first mortgage generally does not carry over to a new one. Plan on a fresh signature.
A low appraisal. A drop in value cuts total allowed debt. It can also trigger a re-test by the second lender, which can sink a subordination that looked settled.
A revolving second. If the lender counts the full limit rather than the drawn balance, room shrinks even when the line is mostly unused. Closing the line at payoff removes the issue.
A first mortgage that bars junior liens. Some servicers and some non-QM first mortgages restrict subordinate financing. That matters most when an investor wants to add a second instead of refinancing, and the answer should be confirmed in writing.
Short-term-rental collateral. Short-term-rental cash-out sits lower: 70% on a cash-out, against about 75% for standard long-term rentals in the same network. Programs typically expect a 640+ score and about 12 months of hosting history. 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.
Coverage below the line. A rental that cannot reach 1.00 after the larger payment may still be reviewed through select lenders in the network, with leverage and terms adjusted. The tradeoff is real: lower leverage means less cash out.
Ineligible property types. Manufactured homes, single- and double-wide, log homes, and barndominiums are not offered in the network’s DSCR programs. A second lien on one of those does not change that.
Entity title. Vesting the property in an LLC can work, depending on program guidelines. The lien analysis is the same, but guarantor and documentation requirements differ.
Key Terms Defined
Combined loan-to-value (CLTV): Total debt from all liens divided by appraised value.
Subordination agreement: A signed document that lets a new first mortgage take first position ahead of an older second lien.
Seasoning: The period of ownership, measured from title recording, before a property is eligible for cash-out; about 6 months is common.
PITIA: Principal, interest, taxes, insurance, and any association dues, which together form the monthly obligation in the coverage test.
Debt service coverage ratio (DSCR): Rent used for lender review divided by PITIA, which shows whether the property’s income covers its own payment.
Net proceeds: Cash to the borrower after lien payoffs, closing costs, and any amounts held back.
What Does the Investor Decision Look Like in Practice?
The decision usually comes down to three choices: pay the second off inside the new loan, keep it with a subordination, or wait. The right answer depends on what the second costs, what the investor does with the cash, and how much cushion the rent leaves.
| If your situation is… | The usual lean |
|---|---|
| Second lender is slow or uncooperative | Roll it into the new first |
| First mortgage is cheap and worth keeping | Weigh keeping it, if the first allows a subordination |
| Coverage lands near the floor | Take less cash or wait |
| Value just dropped | Wait for a fresh appraisal |
| Cash will fund another purchase that cash-flows | Cash-out can pencil |
Rolling the second in gives one lien and one payment. It also reprices the whole balance, including a low-cost first if you had one. That tradeoff is the main cost of simplicity.
Keeping the second preserves cheap first-lien debt, but adds a payment and leaves later refinances dependent on that lender’s cooperation. It is worth the extra step only when the existing first mortgage is clearly worth protecting.
Taking the full amount is not always wise. Pulling the maximum can erase whatever cash flow the property produced. Many investors choose a smaller pull so the file keeps real breathing room.
A net-proceeds checklist keeps the planning honest:
- Confirm every recorded lien from the title search.
- Get payoff statements for the first and the second.
- Estimate closing costs against the room left.
- Check reserves separately from proceeds.
- Re-run coverage on the full new obligation, with and without the second’s payment.
Common mistakes follow the same pattern. Investors forget a lien, assume a junior lender will sign, count on a higher rate-and-term tier, or treat passing coverage as proof the property makes money. Each of these is avoidable with a title search and a clear read of the program.

Frequently Asked Questions
Can a cash-out refinance on a rental pay off my second mortgage?
Yes, the second can be paid off inside the new first mortgage, subject to lender guidelines. The combined balance is then tested against the 75% cap on a standard rental cash-out. You end up with one lien and one payment, but the whole balance reprices.
Does keeping a second lien give me more cash than paying it off?
No. The cap applies to total debt, so the cash before costs is the same either way. Keeping the second preserves the first-lien terms you already hold, but it needs the second lender’s signature and may add that payment to the coverage test.
What if my second lender will not subordinate?
The usual fallback is to pay the second off and take a single larger first-lien cash-out. That works only if the combined balance fits under the leverage cap and rent covers the larger payment. A low appraisal can make this path tighter.
Does a refinance that only pays off a second count as a cash-out?
Often yes. A second lien that did not fund the purchase generally pushes the refinance into cash-out treatment even when no cash comes back.
Does passing the coverage test mean the rental cash-flows?
No. The coverage ratio compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside it, so a file can clear 1.00 and still lose money in a weak year.
