The Quick Read: It depends on what happens to your existing first mortgage. A cash-out refinance replaces the first loan with a larger one and pays you the difference, while a second lien sits behind the first and leaves it untouched. Keep the first loan if its terms are worth protecting and you need a bounded amount of cash. Replace it if you want one payment, the largest lump sum, or the first loan isn’t worth keeping.
- A cash-out refinance reprices the whole balance; a second lien prices only the new money.
- On most files in Lendmire’s wholesale network, cash-out tops out around 75% LTV on a standard rental, with about 6 months of seasoning.
- A second lien adds a payment, so rent has to cover the combined debt service.
- Clearing 1.00 coverage does not mean positive cash flow.
- Second liens on rentals are offered by fewer lenders, so availability can decide the question for you.
What Is the Difference in Plain Terms?
A cash-out refinance swaps your old mortgage for a new, larger one. You take the difference in cash. The CFPB describes it this way and notes that closing costs often apply.

A second lien is a separate loan recorded behind the first. It can be a closed-end loan (a lump sum) or a line of credit (draw as needed). Your first mortgage keeps its rate, term, and balance. You simply make a second payment.
That one distinction drives almost everything else. Whole-balance repricing versus new-money-only pricing. One payment versus two. One lender versus two.
Key Terms Defined
- Cash-out refinance: a new first mortgage that pays off the old one and returns the extra as cash.
- Second lien: a loan secured by the same property that is paid only after the first mortgage in a default.
- Closed-end second: a second lien funded as one lump sum with a fixed repayment schedule.
- Line of credit: a revolving second lien you draw on as needed.
- PITIA: principal, interest, taxes, insurance, and association dues, the full monthly housing obligation.
- DSCR (debt service coverage ratio): monthly rent used for lender review divided by PITIA.
- Subordination: an agreement that keeps a second lien behind a new first lien after a refinance.
- Seasoning: how long you must have owned the property before cash-out is allowed.
Which Costs More, and Why?
Neither is always cheaper. A cash-out usually prices lower per dollar because the lender holds first position. A second-lien lender is paid only after the first is satisfied, so it prices that risk higher on the amount it lends. Cash-outs, though, apply the new rate and full closing costs to the whole balance.
So the real comparison is a blended cost. Take the first loan’s cost on its balance, add the second’s cost on the new money, and compare that mix to one new loan on the entire amount.
Three inputs decide the break-even:
- The gap between your current first-mortgage terms and what a new first would carry.
- How much cash you actually need.
- How long you will hold the property.
A low-cost first loan with a modest cash need favors the second lien. A first loan with expensive terms, or a large cash need, favors the cash-out. If you plan to sell or refinance within a short window, the extra closing costs on a cash-out have less time to pay off.
How Does Coverage Change Under Each Path?
Both options lower your DSCR. They do it differently.
A cash-out raises the balance on one loan, so rent is tested against a single, larger payment. A second lien leaves the first payment alone and adds another, so rent is tested against the combined payments. In both cases coverage falls from where it started.
Across the wholesale network, 1.00 is where select programs start, not a universal standard. Stronger coverage opens better pricing and leverage. Some select lenders in the network will review coverage below 1.00, with leverage and terms adjusted.
Here is the part landlords miss. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capex all sit outside the calculation. A property can clear 1.00 and still lose money in a bad month. Run your own cash-flow numbers before borrowing, not just the lender’s ratio.
What Do Lenders Actually Allow?
For a cash-out on a standard rental, most programs in the network cap leverage around 75% LTV, with about 6 months of seasoning measured from title recording. A short-term rental cash-out is lower, around 70% on that collateral. Credit floors begin at 620 in parts of the network, most programs want around 660, and 700 and up unlocks the strongest tiers. Loans generally run from about $100,000 up to $3,000,000, and reserves commonly sit near 6 months of PITIA, stepping up to roughly 9 months on larger balances. These are typical ranges, subject to lender guidelines, and every file is reviewed individually.
Consumer guidance gives a useful contrast. The CFPB’s home equity guide says lenders typically want you to keep roughly 10% to 20% equity after borrowing. That is an owner-occupant benchmark, not a DSCR figure. For a rental, use the network’s 75% ceiling instead.
Equity is only one test. A larger equity cushion helps, but it does not erase credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
Which Landlord Are You?
| Your situation | Usually leans toward |
|---|---|
| Cheap first mortgage, modest cash need | Second lien |
| Expensive first mortgage, large cash need | Cash-out refinance |
| Existing second you want to fold in | Cash-out refinance |
| Prepayment penalty on the first loan | Second lien, or wait |
| Property held in an LLC | Cash-out (title rules matter) |
| Thin rental coverage already | Smaller draw, or neither |
| Want the simplest exit later | Cash-out refinance |
Treat these as starting points. The flip points are real. A cheap first mortgage on a property you plan to refinance again soon may still be better served by a cash-out, since stacked liens complicate that later move.
What Is the Catch With a Second Lien?
Availability. Closed-end seconds on rentals are offered by fewer lenders than first-lien cash-outs, and many banks don’t write investment-property lines at all. Those that do typically underwrite you personally, on credit and debt-to-income, not on rent. Bank-style lines also tend to want personal or revocable-trust title.
Then there is sequencing. A second lien does not change your first loan’s terms, but it can complicate a later refinance of that first loan. The new lender may require the second to be paid off or subordinated, which needs the second lender’s consent. Check this before you stack a lien.
Check two more items in the note itself: whether the first mortgage permits a junior lien, and whether a prepayment penalty applies. A penalty makes retiring the first loan through a cash-out more expensive.
What Is the Catch With a Cash-Out?
You reprice everything. If your current first mortgage has terms worth keeping, a cash-out gives them up on the whole balance. You also pay closing costs on the full new loan, and a new 30-year term resets your payoff clock.
The upside is simplicity. One loan, one payment, one lender, and a cleaner path to future sales or refinances. Cash-outs also commonly accept LLC title, subject to program terms, which matters if you hold rentals in an entity.
Extended terms such as 40-year amortization and interest-only periods are available through select lenders in the network. ARM structures exist too. These can help coverage, but they trade lower early payments for different long-run costs.
A Worked Comparison
Take a rental with no existing second lien and a first mortgage you would happily keep. Say you want a bounded amount of cash for a renovation.
Path one, second lien. Your first payment stays put. The second adds its own payment. Rent tested against both lands the file at, say, roughly 1.05x coverage. That is thin, but it clears 1.00 for a program that starts there.
Path two, cash-out. The first loan is replaced by one larger loan at a new rate, and rent is tested against that single payment. If the new first is priced higher than your old one, coverage might land near 1.10x, a bit stronger on paper, but you gave up your old terms on the entire balance.
Those coverage figures are illustrative assumptions, not market data. The point is the shape of the trade. The second protects a cheap first loan at the price of a higher cost on the new money. The cash-out costs more up front and resets the whole loan, but it leaves you with one clean lien. Neither wins automatically.
A Pre-Decision Checklist
Before choosing, work through these:
1. Is the first mortgage worth keeping, on its terms alone?
2. Does rent cover the combined payments (second) or the single larger payment (cash-out)?
3. How is the property titled, personally or in an LLC, and does the product accept that title?
4. Does the note allow a junior lien, and is there a prepayment penalty?
5. Do you plan to refinance or sell soon, and how would a stacked lien affect that?
6. Will the cash earn its keep? If the use doesn’t produce more than the borrowing costs, skip both.
For documents, expect a lease or a market-rent appraisal (Form 1007 for single-family, Form 1025 for two to four units), title and vesting documents, the payoff statement on the first lien, and entity documents if the property is in an LLC.
Either option puts the property at risk. The CFPB notes that missed payments on a home-equity-backed loan can lead to foreclosure on the collateral. The same logic applies to a rental, and stacking leverage on a property with thin coverage is where landlords get hurt when rents soften.
Common Misconceptions
“A cash-out always costs more.” The new rate applies to the whole balance, but a second can cost more per dollar borrowed. Compare the blended cost.
“A second lien leaves my first mortgage alone, so it’s harmless.” It leaves the first loan’s terms alone. It can still complicate a later refinance.
“If the ratio passes, I’m safe.” The ratio compares rent to PITIA. It ignores vacancy, repairs, and reserves.
“Any bank line works on a rental.” Many banks don’t lend on investment property, and those that do underwrite you personally.
“Consumer 80% limits apply here.” Those are conventional owner-occupant figures. Cash-out leverage in the network tops out around 75% on a standard rental.
What Should You Do Next?
Start with the first mortgage. Pull the note, check the rate, the prepayment terms, and whether a junior lien is allowed. Then run the combined-payment coverage and the single-larger-payment coverage side by side, and stress both against a month of vacancy.

Frequently Asked Questions
Is a second lien easier to get than a cash-out refinance?
Not on a rental. Fewer lenders offer closed-end seconds on investment property than offer first-lien cash-outs, and many banks decline investment-property lines altogether. Where a bank does lend, it usually underwrites you personally rather than the property’s rent. A cash-out through a DSCR program is often the more available route.
Can I do both, a cash-out and a second lien?
Sometimes, but the second lien has to fit behind the new first. Stacking raises combined leverage and lowers coverage, and a later refinance may require the second to be paid off or subordinated. Many landlords pick one structure per property to keep the exit simple.
What if my rental is in an LLC?
It narrows the options. Bank-style lines generally want personal or revocable-trust title, while DSCR cash-outs commonly accept an LLC, subject to program terms. Confirm title requirements before you commit to either path.
Does a second lien hurt my coverage more than a cash-out?
Not necessarily. Both lower coverage. A second adds a payment on top of your existing one, while a cash-out enlarges one payment. Which hurts more depends on how your current first loan compares with a new one and how much cash you take.
How much equity can I pull out of a rental?
On a standard rental, cash-out leverage tops out around 75% LTV across most of the network, so you keep at least 25% equity. Short-term rental collateral is lower, around 70%. What you can actually take depends on rent used for lender review, the full payment, reserves, and credit, so treat 75% as a ceiling, not a promise. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
