The Quick Read: Usually yes, because a cash-out refinance pays you only the value above the existing payoff, and an underwater rental has no value above its debt, so it adds risk and no proceeds to the new loan.
- Cash-out on a standard rental tops out around 75% LTV across most of our wholesale network, and that cap applies to value, not to what you owe.
- On separate loans, the underwater house stays on its current note while the equity-rich properties refinance on their own merits.
- A blanket (pooled) loan is where including it gets risky: one lien set, cross-default exposure, and release-price friction.
- Strong rent cannot create equity that does not exist, and equity cannot fix weak rent coverage.
- If the shortfall is small and you have cash, paying it down is a cure. Cash goes in, not out. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
What Does “Underwater” Mean for a Rental?
A rental is underwater when you owe more than it is worth. Appraised value minus total payoff gives your equity. If the answer is negative, there is nothing to cash out.

A cash-out refinance replaces your old loan with a larger new one. The new loan pays off the old one, covers closing costs and any prepayment penalty, and hands you the difference. On an underwater property that difference is zero or less. The new loan would have to be sized at or above the old payoff, and the leverage cap sits on value, not on debt.
Lenders say it plainly: you cannot borrow against value that isn’t there.
Can You Refinance One Rental and Skip Another?
Yes, when each property sits on its own loan. Each house has its own note, lien, coverage test, and exit path. Refinancing the equity-rich ones does not touch the underwater one. Lendmire’s complete DSCR loans guide walks through how those single-property loans are built.
Seasoning matters on the properties you do refinance. Most programs want about 6 months of ownership, measured from title recording, before they will pay out cash. Equity in the stronger houses is then sized against the 75% LTV ceiling on cash-out, reserves, and rent coverage. It is never a guaranteed cash figure.
The exclusion gets harder when your loans are bundled. A blanket loan puts several properties under one note. Then you cannot simply “leave one out” without restructuring, and that is where the real decision sits.
Why Blankets Make an Underwater Rental Dangerous
A blanket loan secures every property against the whole balance. Add a weak asset and you have added a weak link to the chain.
Fortune Builders calls the biggest threat in cross-collateralization the potential to lose one or more assets after falling behind on payments. Corporate Finance Institute notes that cross-collateralized assets require every loan to stay in good standing, or the borrower risks defaulting on all of them.
Here is how that plays out in a pool:
- Blended coverage can hide the weakness. Picture a weak fourth property testing near 0.85x. On its own, on a separate loan, it fails the coverage test. Inside a pool it can land near a blended 1.15x. The ratio looks fine. The risk did not go away.
- Tougher requirements. Blanket structures can carry stricter coverage rules than the same properties on separate notes.
- Cross-default. One struggling property can expose the rest to enforcement.
- Release friction. Without a release clause, selling one property can force payoff of the whole loan. Even with one, release pricing often exceeds the property’s share of the debt, so net cash is smaller than the paper equity suggests.
Separate notes keep a problem local. That is the strongest argument for leaving the underwater house on its own loan.
How the Excluded Rental Still Affects You
Leaving a property out of the new loan does not make it disappear. Its payment still exists, and you still have to make it. If it loses money each month, that drain comes out of the same reserves you need to show on the refinance.
Reserves vary by lender, leverage, loan size, and transaction type. Commonly they run around 6 months of PITIA (principal, interest, taxes, insurance, and any HOA dues), stepping up to about 9 months above $1,500,000. A negative-cash-flow rental you are carrying competes for that same cash.
One more point: DSCR compares rent to PITIA only. Clearing 1.00 is not the same as positive cash flow. Repairs, vacancy, management, utilities, and capex sit outside the calculation. A rental can pass coverage and still bleed you monthly.
A Two-Property Illustration
This is an illustrative scenario with modeled assumptions, not a market fact.
Say you own Property A and Property B on separate loans. A has meaningful equity and rents that cover its full payment at roughly 1.25x. B is underwater and covers at about 1.0x on paper, but carries a second lien.
| Move | Result on A | Result on B |
|---|---|---|
| Cash-out A alone | Proceeds sized to 75% LTV cap | Untouched, same note |
| Blanket both | Pool tested together | B becomes collateral for everything |
| Pay down B first | Uses cash you might have kept in reserve | Moves toward a workable LTV |
The clean path is the first row. Property A is evaluated on its own value, rent, credit, and reserves. B keeps its loan, its second lien, and its problems, but they stay contained.
Leave It Out, Cure It, Hold It, or Sell It?
| Option | What it does | Cash needed | Best when |
|---|---|---|---|
| Leave it out | Keeps B on its own note | None extra | Loans are separate |
| Cure the shortfall | Pays principal to restore workable LTV | Cash in | Gap is small, cash is spare |
| Hold for paydown | Waits for paydown and appreciation | Monthly carry | Property cash flows or breaks even |
| Sell or short sale | Exits the asset | Varies | Carry is unsustainable |
BiggerPockets commenters describe the investor’s real choices as injecting capital to restore a workable LTV, or holding at break-even and waiting. Those are investor opinions, not rules. The same thread warns that a short sale can hurt credit and may block future conventional purchases, and that a second lender can refuse to let go.
Walking away also carries tax and legal consequences, including a possible deficiency bill. Tax treatment varies; consult a qualified professional.
How to Decide
Run these questions in order:
1. Are the loans separate or blanketed? If separate, leave the underwater house out. If blanketed, ask whether a release clause lets you carve it out.
2. Is the shortfall small? If so, and you hold real reserves, a paydown may be cleaner than carrying it.
3. Does it cash flow? An underwater rental that covers its costs can be held. One that drains you each month is a different conversation.
4. Is there a second lien? It still counts toward combined debt even if you refinance only the first.
5. Can you stress-test the portfolio? If B stays negative for a year, do you still clear reserves on the loans you are refinancing?
The choice between paying down the underwater loan and holding it is a genuine toss-up for borderline files. Paying down B can feel responsible, but it spends cash you may need as reserves. Holding it can feel passive, but it keeps your liquidity intact.
Mistakes That Cost Investors
- Using good-asset equity to bail out a bad asset with no plan. Pulling cash from A to prop up B only helps if B has a path to recovery.
- Planning around phantom equity. Equity on paper is not cash in hand. Run proceeds only on properties that truly have equity.
- Pooling to hide a weak ratio. A blanket can pass coverage while adding cross-default exposure.
- Assuming a blanket always saves money. Savings come from per-loan fees, not cheaper money, and they shrink if you sell doors one at a time.
- Assuming rent decides everything. An investor with plenty of equity can still be declined if the loan is sized against weak property income. The reverse holds too.
Credit and coverage still matter on the files you do refinance. A 620 score is the floor in parts of our network, most programs want around 660, and 700+ opens the strongest leverage tiers. Coverage of 1.00 is where select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Neither path solves negative equity, because the LTV cap still binds. All of it is subject to lender guidelines and individual underwriting.
Key Terms Defined
Underwater: owing more on a property than it is worth.
Cash-out refinance: a new, larger loan that pays off the old one and returns the difference to you.
Cross-collateralization: using several properties as security for one loan or one pooled balance.
Blanket loan: a single loan secured by multiple properties.
Release clause: a term that lets one property leave a blanket loan, usually for a price.
PITIA: principal, interest, taxes, insurance, and any HOA dues, the full monthly obligation DSCR is measured against.
Frequently Asked Questions
Can I cash out on a rental that is worth less than I owe?
No. A cash-out pays only value above the payoff, and the leverage cap of about 75% applies to value. With negative equity there are no proceeds to release. The practical move is refinancing your other properties and leaving this one alone.
Is an underwater rental only a problem if I sell or refinance it?
Mostly, yes. If you stay current and the rent carries it, you can hold it. The trouble shows up when you want to sell, refinance it, or fold it into a pooled loan. It also still draws on your reserves while you carry it.
Will an excluded rental hurt my approval on the other properties?
It can, indirectly. It is not part of the new loan’s coverage test on separate notes, but its payment and any monthly losses still eat into the cash you show for reserves, which commonly run around 6 months of PITIA.
Should I just walk away or short sell it?
Not as a first move. Investors report that a short sale can hurt credit, leave a deficiency bill, and block future conventional financing. Talk to a CPA or attorney before choosing.
Does a lower-than-1.00 coverage program help an underwater property?
It helps with rent coverage, not equity. Sub-1.00 coverage is available through select lenders in the network, with leverage and terms adjusted, but the LTV cap still applies to value.
