The Quick Read: A BRRRR batch can carry only as much vacancy as its pooled coverage ratio, the leverage cap, and the lease-or-market-rent rule allow, and that depends on whether the rentals sit under one blanket note or separate loans, because separate loans are judged one property at a time while a blanket note blends them. No lender publishes a flat vacancy percentage for a batch. The capacity is math you can run before you apply, subject to lender guidelines.
- Separate loans test each rental on its own. A blanket note tests the pooled rent against the pooled debt service.
- A vacant rental that is finished and rent-ready is treated very differently from one that is still under construction.
- Vacant units are usually counted at an appraiser’s market rent, not at zero. Some files are stress-tested at zero anyway.
- Clearing the coverage test does not mean the batch has positive cash flow. Vacancy, repairs, and management sit outside the ratio.
What Counts as a Batch?
A batch is two or more rehabbed rentals refinanced out of bridge or hard-money debt around the same time. The word has no lending definition. What matters is how the lender packages them: as separate loans or as one pool.
Across Lendmire’s wholesale network, the packaging is one of the main things that shapes how vacancy gets judged. Here is the structural difference.
| Factor | Separate loans | Blanket (pooled) loan |
|---|---|---|
| Coverage test | Per property | Pooled rent vs pooled debt |
| Vacancy judged | Per property or unit | Across the whole pool |
| Weak property | Can fail alone | Offset by stronger ones |
| Collateral | Each property alone | Properties tied together |
Two blanket structures exist in the network. The 30-year portfolio DSCR loan covers 2 to 20 properties under one note, typically from $300,000 to $5,000,000, with leverage up to 80% of value on a purchase or rate-and-term refinance and a 1.00 coverage floor measured on the pool. The rental portfolio term loan covers five or more rentals or units, typically from $500,000 to $50,000,000, with leverage up to 75% of value and fixed terms with a balloon at maturity. Both are subject to lender guidelines. Neither is the same product as a standard DSCR loan on one rental.
Are Vacant Rentals Eligible at All?
It depends on the transaction. On a purchase, a vacant property in turnkey condition is routinely allowed. On a refinance, most programs want a lease or an operating history, because the whole point of the loan is that the property already produces rent.
DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage. That also means a vacant unit cannot be a place the borrower moves into during lease-up. Owner-occupied property is ineligible in the pool.
Multi-unit buildings are where lenders flex. Some will accept one or two vacant units on a refinance if those units are rent-ready, meaning a tenant could move in now. A single-family rental with no tenant is the hardest case, since there is no other unit to show income.
Condition matters as much as occupancy. A vacant unit with finished work and a listing is a leasing question. A unit with open permits or missing fixtures is a construction question, and lenders do not treat it as rentable.
How Does the Pool Treat a Vacant Rental?
Every property in a pool still needs a lease or an appraiser-supported market rent. A signed lease covers an occupied unit. For a vacant unit, the appraiser’s rent opinion stands in for the lease.
Appraisers borrow vocabulary from the agency world here. A single-family comparable rent schedule, form 1007, gives the rent opinion on a one-unit rental. For 2-4 units, the small residential income property report, form 1025, is the matching format. DSCR loans are not bound by agency rules. The forms are simply what appraisers know how to produce.
Two practical points follow.
- The lender’s rent figure, not the investor’s hoped-for rent, carries the vacant unit. Where a lease and a market opinion differ, programs generally lean toward the lower number.
- Vacancy is not a line in the ratio. It shows up through the rent source, a possible leverage trim, and any stress test the program applies.
A rental that falls below 1.00 on its own can sit in a pool, but what underwriting tests is the pooled coverage, the leverage, and the terms. It does not turn the file into a below-1.00 program. Programs below 1.00 coverage exist through select lenders in the network, with leverage and terms adjusted, and that is a separate path from the pooled test.
The Capacity Formula: How Many Empty Units Can the Pool Absorb?
The pool can absorb vacancy equal to one minus the inverse of its blended coverage. In plain terms, the maximum vacant share of rent equals 1 − (1 ÷ blended coverage), assuming vacant units earn zero. This is a modeled stress, not a lender rule.
Run it with these modeled assumptions: ten similar rentals, each covering its own debt service at 1.25x. Treat vacant rent as zero, which is the harshest reading.
| Vacant of 10 | Pooled coverage | Read |
|---|---|---|
| 0 | 1.25x | Clean |
| 1 | about 1.13x | Passes the 1.00 floor |
| 2 | 1.00x | Sits exactly on the floor |
| 3 | about 0.88x | Fails the pooled floor |
At 1.25x blended coverage, the pool tolerates 20% of its rent going dark. At 1.10x, the tolerance shrinks to about 9%. At 1.40x, it grows to about 29%. The stronger your leased properties, the more room the weak ones get.
If the program instead counts vacant, rent-ready units at the appraiser’s market rent, the ratio does not move at all. The question then shifts to leverage and documentation. Ask the lender in writing which reading applies before you build the batch around one.
The pool also has limits that coverage math will not show. Leverage still tops out at the structure’s ceiling. Cash-out on a pooled loan never exceeds 75% of pooled value. The credit floor is typically 640 for the pool, rising to 680 or 720 on some structures, and a special-purpose entity (typically an LLC) is required on some structures, subject to program terms.
Passing the Ratio Versus Surviving the Month
The ratio compares rent to PITIA only. It does not count repairs, vacancy, management, utilities, or capex. A batch can clear the coverage test and still bleed cash.
Take the same ten-property pool at 1.25x with two units empty. If vacant rent counts as zero, coverage sits at 1.00x. In real life that means the remaining rent covers the loan payment and nothing else. Repairs, management, and every vacant unit’s utilities come out of your reserves.
Reserves vary by lender, leverage, loan size, and transaction type. On a loan against a single rental, about 6 months of PITIA is common, and loans above $1,500,000 typically step up to about 9 months. Pooled structures follow their own rules. The rental portfolio term loan holds reserves for taxes, insurance, and capital expenditures. Size your liquidity for the worst month of the batch, not the average one.
Where the Rule Breaks
Five edge cases account for most surprises on batch files.
1. Seasoning is a separate gate. A tenant in place does not clear it. About 6 months is the common expectation for cash-out. On a pooled loan, leverage in the first six months is limited to 90% of total cost, and from six to twelve months it is 100%. A rate-and-term refinance carries no cost restriction. For the cash-out side, see Lendmire’s piece How Much Cash a BRRRR Investor Gets on a DSCR Refinance by Seasoning.
2. Rehab dates differ. If one property finished work two months before another, the later one may be vacant and inside the cost-based limits while the earlier one is stabilized. The batch is only as ready as its newest unit.
3. Lease paperwork gaps. BRRRR investors often have a tenant but not a 12-month lease, deposit proof, or proof of the first month’s rent. A missing document can turn an occupied unit into an undocumented one.
4. Half-empty buildings. Some lenders treat a building with a large share of vacant units as unleased. That is one program’s rule, not a universal one, so ask per lender.
5. Ineligible property. Manufactured homes, log homes, barndominiums, mixed-use, commercial property, co-ops, and mobile homes are not offered. One of these in the batch can sink the pool.

Refinance Now, Lease First, or Split the Batch?
The right move depends on how many units are empty and how much cushion the stronger ones give. Use the table as a starting decision frame.
| Situation | Usual move |
|---|---|
| All units leased, pool clears floor | Refinance the batch together |
| One or two empty, strong cushion | Ask for market-rent treatment, then refinance |
| Several empty, thin cushion | Lease first, then apply |
| One weak asset drags the pool | Split it into its own file |
| Rehab unfinished on one unit | Hold it out until rent-ready |
Splitting has a cost. Each separate loan stands alone, so you give up the offset between strong and weak properties. Leaving a weak unit out of the pool keeps the blend clean, but it leaves that unit on bridge debt, where interest keeps accruing. Both are real trade-offs, and neither is free.
What to Have in the File
Clean paperwork removes the preventable gaps. For each property, assemble:
- A signed lease, deposit proof, and first-month rent evidence for occupied units.
- An appraiser rent opinion for vacant units.
- Proof the work is finished and the unit is rent-ready, plus a listing or marketing record.
- Entity documents, where the structure calls for a special-purpose entity.
- Reserves documentation that covers the whole batch, not one property.
Qualification runs primarily on property-level rental income covering the payment, subject to lender guidelines. It still reviews credit, reserves, and property eligibility. For the broader picture, Lendmire’s complete DSCR loans guide covers how the programs fit together. Tax treatment varies; consult a qualified professional.
Key Terms Defined
Blended coverage: The pooled rent divided by the pooled debt payment across every property in a blanket loan.
Rent-ready: A finished unit that a tenant could occupy now, with no open work.
Market rent: The rent an appraiser supports for a unit without a lease behind it.
Seasoning: The ownership period a lender requires before it allows cash-out against a recent purchase or rehab.
Pooled value: The combined appraised value of all properties under one blanket loan, which sets the cash-out ceiling.

Frequently Asked Questions
Can a vacant rental be refinanced with a DSCR loan?
Sometimes. Most refinance programs want a lease or an operating history, but a few accept a finished, rent-ready unit supported by an appraiser’s rent opinion. Leverage may be trimmed, and every file is reviewed individually.
Can one strong rental carry a vacant one in the same pool?
Only under a blanket loan. A pooled structure measures total rent against total debt service, so a stronger property can offset a weaker one. Separate loans never blend, so each property has to stand on its own.
Does the DSCR ratio include vacancy?
Not as a line item. The ratio compares rent to PITIA. Vacancy shows up through which rent figure is used, any leverage adjustment, and any stress test the program applies.
How much reserve should a batch hold?
Enough to survive its worst month. On a loan against one rental, about 6 months of PITIA is common, and loans above $1,500,000 typically step up to about 9 months. Pooled loans follow their own reserve rules, so confirm them per structure.
What if the pooled coverage comes in short?
You have a few options: lease up the empty units first, remove the weakest property from the pool, or put more equity into the loan. Smaller or different structures may also fit, subject to lender guidelines.
