The Quick Read: A few vacant rentals rarely disqualify a portfolio cash-out refinance, because underwriting swaps each empty unit’s missing lease for an appraiser’s market-rent opinion and then tests the combined rent against the combined payment, so the real question is how much cushion the pool has left. Your outcome depends on that pooled coverage, the size of the pool, and whether the empty units are ready to rent.
- A vacant unit usually counts at appraised market rent, not at zero, though some programs trim that figure.
- Coverage is tested across the whole pool, so strong rentals can carry weak ones.
- Small pools feel vacancy more: one empty door in a three-property pool moves the number far more than one in fifteen.
- Cash-out never exceeds 75% of the pooled value, even though the 30-year portfolio loan allows up to 80% on a purchase or rate-and-term refinance, and the rent-based loan size can cut cash-out lower.
- Clearing the coverage test does not mean the pool makes money after repairs, vacancy and management.
What a Portfolio Cash-Out Refinance Actually Is
A portfolio cash-out refinance puts several rentals under one loan and returns part of your equity as cash. One note is secured by every property in the pool. Lenders call that cross-collateralization. Across Lendmire’s wholesale network, “portfolio DSCR loan,” “blanket loan,” and “cross-collateralized loan” all describe this same thing. (A bank’s own portfolio loan, one it keeps on its books instead of selling, is a different use of the word.)
DSCR stands for debt service coverage ratio. For a rental it is monthly rent divided by PITIA, which is principal, interest, taxes, insurance, and any association dues. The general finance definition uses net operating income and treats a result under 1 as a shortfall, per Wikipedia’s debt service coverage ratio entry. Rental loans simplify this by using rent and PITIA. For the broader mechanics, the complete DSCR loans guide covers the basics.
Two structures matter here, and the network treats them differently:
- The 30-year portfolio DSCR loan covers two to twenty properties under one note, with loan sizes from $300,000 to $5,000,000 and larger balances on review. It allows leverage up to 80% of value on a purchase or rate-and-term refinance. The coverage floor of 1.00 is measured on the pool, with an interest-only period available.
- The rental portfolio term loan is for five or more rental properties or units under one loan. Balances run from $500,000 to $50,000,000, with leverage up to 75% of value and fixed terms of 3, 5, 7, or 10 years that end in a balloon payment. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Both are subject to lender guidelines, and every figure is a ceiling or floor, never a quote.
How Underwriting Treats a Vacant Rental, Step by Step
Underwriting treats a vacant rental as a unit with no lease income, so it substitutes the appraiser’s market-rent opinion and retests the pool. The sequence is predictable even though details differ by lender.
1. Each property is appraised. The appraisal sets value, which sets the leverage ceiling. It also supplies the market-rent opinion.
2. Each unit gets a counted rent. A leased unit generally counts the lower of the lease or market rent. A vacant unit counts market rent alone. Some programs trim that figure with a vacancy haircut, and others do not.
3. The pool is totaled. Counted rent from every property is added up and divided by the total PITIA across the pool.
4. Coverage is compared with the floor. On the 30-year portfolio loan, pooled coverage must reach 1.00. A pool that tests below that floor does not qualify on this structure.
5. Proceeds are sized. Cash-out is the lower of the value-based loan size and the rent-based loan size, minus payoff and closing costs. Equity is not the same as net cash.
6. The file is documented. There is usually one master package for the borrowing entity, plus a set of exhibits for each property covering ownership, rent, value, and insurance. A vacant unit typically adds a letter explaining why it is empty and what the plan is.
The pool must also pass the usual checks. The credit floor on the portfolio programs is 640, and some portfolio structures ask for 680 or 720. Some structures require a special-purpose entity, typically an LLC, and recourse loans carry a personal guarantee. Owner-occupied property, co-ops, mixed-use property, and commercial property are ineligible inside the pool.
Where the rent number comes from
The appraiser, not you, supplies the rent for a vacant unit. For a single-family investment property that opinion usually lands on a standard rent schedule form (Form 1007 in Fannie Mae’s numbering). Two-to-four-unit buildings use the sister form, Form 1025. These are appraisal tools. They are named here only because the document you will see in a DSCR file looks much like them, and agency lending rules do not govern these loans.
The appraiser works from monthly lease comparables. Fannie Mae’s appraiser update on market rent says an appraiser should not take nightly short-term-rental rates and multiply by 30. If your vacant unit was an Airbnb, expect a lower monthly-rent opinion than the nightly numbers suggest.
How Each Kind of Vacancy Is Typically Treated
Treatment varies by program, but the pattern is consistent. A rent-ready empty unit is the easiest case. An unfinished renovation is the hardest.
| Unit status | Typical rent counted | File impact |
|---|---|---|
| Leased, current | Lower of lease or market | Cleanest |
| Month-to-month or expired lease | Often market rent | Weaker file |
| Vacant, rent-ready | Market rent, sometimes trimmed | Usually workable |
| Vacant, under repair | Program by program | May need a cure |
| Nonpaying tenant | Market rent or zero | Re-rated, then retested |
| Vacant short-term rental | Monthly-lease market rent | Lower than nightly math |
Notice what separates the rows: whether the lender can trust a rent figure. A unit with a market-rent opinion and a clear listing gives underwriting something to count. A gutted unit with no finish date gives it nothing, and a pool can absorb only so much of that.
Worked Example: One Pool at Zero, One, and Two Empty Doors
The sharpest way to see the effect is to run one pool through the stress cases. Treat these as modeled assumptions, not program terms. Say you own five similar rentals, each with the same rent and the same payment, and the pool covers at roughly 1.30x when every door is counted.
- No vacancies: pooled coverage sits near 1.30x, comfortably above a 1.00 floor.
- One door counted at zero: four of five rents remain against five payments, which puts coverage near 1.04x. The pool still clears, but barely.
- Two doors counted at zero: three of five rents remain, and coverage drops near 0.78x. The pool fails the floor.
If the empty doors count at appraised market rent instead of zero, the picture is far better, since the counted rent barely moves. The zero case is the stress test. It applies when a unit is not rent-ready, when a lender trims vacant rent, or when a tenant has stopped paying.
Pool size matters just as much. Picture a three-property pool at about 1.40x. Counting one door at zero cuts it to roughly 0.93x, which is under a pooled 1.00 floor. At that point a lender may ask you to cure the unit, re-lease it, pull it from the pool, or wait. A fifteen-door pool with one empty unit barely notices.
A quick rule for your own planning: a pool at 1.30x can lose about a fifth of its counted rent before reaching 1.00. A pool at 1.10x can lose less than a tenth. Run your pool at market rent and again with the problem unit at zero before you apply.
Why Vacancy Also Shrinks Your Cash-Out
Vacancy cuts your proceeds even when the pool clears the floor. Cash-out is sized to the lower of two numbers: what the value supports and what the rent supports. Less counted rent means a smaller rent-based loan size, and that smaller number can bind before the leverage cap does.
For a portfolio cash-out, the ceiling is 75% of the pooled value, and never above the structure’s own ceiling. Cash-out proceeds are available on seasoned properties, which means about six months of ownership measured from title recording. Inside the first six months, the loan is also capped at 90% of total cost (purchase price plus documented improvements), and at 100% of total cost from six to twelve months. The leverage ceiling still applies, so the loan is the lower of the two. After twelve months the appraised value alone is the basis. A rate-and-term refinance is not subject to the cost-basis cap.
One more point before you count your cash. A pool that clears 1.00 has shown only that rent covers PITIA. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation. A pool can pass and still lose money in a bad month.
Where the General Rule Breaks
Three situations push a vacancy from tolerable to problematic.
A small pool. Each door carries a large share of the rent. A single empty unit can move a three-property pool below the floor, as the example showed.
An unfinished renovation. Normal turnover and an unfinished rehab are different conditions. Eligibility for non-rent-ready property is a program-by-program question, so ask early instead of assuming. Manufactured and mobile homes are not reviewable on any of these programs, whatever their condition.
A tenant who has stopped paying. A rent-ready vacant unit is generally easier to underwrite than a tenant months behind. Unpaid-rent situations are typically re-rated to market rent or zero, then the pool is retested.
A weak rental can still sit in the pool when underwriting tests the pooled coverage, the leverage, and the terms together. That is the benefit of pooling. It is also the risk, because the loan is cross-collateralized: one struggling property can put the whole note under pressure.
Release terms deserve attention too. Partial releases, substitutions, and the sale of one property out of the pool follow your loan documents and the lender’s release terms. The remaining pool must still cover its debt service. The release price runs above the property’s allocated balance, so selling one property to fix the pool may cost more than the balance allocated to it. Read those terms before you sign, not after a vacancy appears.
Pooled and separate loans also differ on a point that matters here. In a pool, strong properties can offset a weak one. Under separate loans, each vacant house must qualify on its own, and it cannot drag the others down.
A Decision Tree for Your Own Pool
Your three paths are pool everything, pool minus the weak properties, or separate loans.
Pool everything when your pooled coverage still clears 1.00 with the empty units counted at the conservative figure. This keeps one note and one closing, and it lets strong doors carry the weak ones.
Pool minus the weak properties when one or two units drag coverage under the floor or are not rent-ready. Leave them out, refinance the rest, and bring the weak ones in after they lease. You give up some cash-out today and keep the pool’s coverage clean.
Separate loans when the vacancies are scattered and you want to avoid cross-collateral exposure. Each property stands on its own rent and value. A vacant house can then fail without tipping the others, though you lose the pooled offset.
Before choosing, work through these questions in order:
1. Does the pool clear 1.00 with every vacant door at market rent? If not, you have a structural problem.
2. Does it clear with the worst unit at zero? If yes, you have cushion.
3. Is the empty unit rent-ready, and can you lease it before you apply? If yes, lease first.
4. Would you want to sell any of these properties soon? If yes, read the release terms before pooling it.
For the leasing question, the strongest evidence is a unit that is clean, listed, and priced to market. A rent-ready condition, an active listing, and a short explanation letter are the proof most lenders look for.
Checklists for the File
- Proof of ownership and title, with the recording date for seasoning
- A current lease, or an appraiser-supported market rent if vacant
- Appraisal with the market-rent opinion
- Insurance evidence
- For vacant units, a letter of explanation and listing or rent-ready proof
- Entity formation documents and, where required, a special-purpose entity
- Credit review for the guarantors, against the 640 floor or the higher floor on some structures
- Reserves evidence, which varies by lender, leverage and loan size (the term loan holds reserves for taxes, insurance and capital expenditures)
- A schedule of every property in the pool with rents, payments and balances
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.
Key Terms Defined
Blended (pooled) coverage ratio: the combined counted rent of every property in the pool divided by the combined PITIA. Strong properties can offset weak ones.
Market-rent opinion: an appraiser’s estimate of what a unit would rent for, built from comparable monthly leases. It replaces a missing lease.
Seasoning: the waiting period after you take title before a lender will return cash. For a cash-out on this structure, about six months of ownership from title recording.
Release clause: the loan term that governs how a property can leave the pool, usually at a price above its allocated balance.
Cross-collateralization: one loan secured by several properties, so trouble at one can affect them all.
What This Means for Your Decision
Treat vacancy as a coverage problem you can measure before you apply. Re-rate the pool twice, at market rent and with the weak unit at zero. If the second number still clears 1.00 with room to spare, a pooled cash-out is realistic, subject to lender guidelines and property review. If it does not, lease up, carve out the weak door, or split the pool.
Plan the cash side too. Turnover after closing still costs money, and coverage is tested at closing, not monthly afterward. Keep reserves for the months a door sits empty.
Frequently Asked Questions
Does one vacant rental kill a portfolio cash-out refinance?
Not typically. The unit is re-rated to appraised market rent, and the pool is retested for coverage, leverage and terms. It becomes a problem when the unit counts at zero and the pool is small, or when it needs repairs that make it ineligible to rent.
Can a vacant unit in a multi-unit building still be part of the pool?
Yes, in many cases. Two-to-four-unit buildings are eligible in both structures, and each unit’s rent is counted separately, so one empty apartment is re-rated while the others keep their leases. Buildings with five or more units are eligible only inside the rental portfolio term loan.
Is a vacant rental under renovation treated like a rent-ready one?
No. A rent-ready unit has a market-rent opinion underwriting can count. A unit mid-renovation may be excluded from the pool or require a cure, and eligibility is decided program by program, so ask before you pool it.
How many vacancies can a pool absorb?
It depends on the coverage cushion and the number of doors. In a five-door pool at about 1.30x, one door counted at zero leaves four of five rents against five payments, which still clears a 1.00 floor. Two empty doors would push it under. Larger pools absorb more.
Does clearing the coverage test mean the pool is cash-flowing?
No. The test compares rent with PITIA only. Repairs, vacancy, management, utilities and capital spending are outside the number, so a pool can clear 1.00 and still lose money.
