The Quick Read: A vacant house in a portfolio loan is credited at the appraiser’s market rent, not at zero. That rent is pooled with the other houses’ rents, and the lender tests the combined coverage against the combined payment. The house still gets its own appraisal, condition review and value check.
- Vacant does not mean zero income. The appraisal’s rent schedule supplies the number.
- Coverage is measured on the pool: total rent over total PITIA, not an average of ratios.
- One weak or unleased house drags the pool, and stronger houses can only offset it with rent a lease or appraisal supports.
- Rent-readiness is the real test. A gutted or mid-rehab house is a different problem from an empty, turnkey one.
- Clearing 1.00 is not positive cash flow. Repairs, vacancy, management, utilities and capex sit outside the ratio.
Across the wholesale network, this is the convention on most portfolio files, though each lender sets its own rules and every file is underwritten individually. Nothing here is a commitment to lend. For the full framework, see the complete DSCR loans guide.
Key Terms Defined
DSCR: Debt service coverage ratio, meaning the property’s rent used for lender review divided by its monthly obligation.
PITIA: Principal, interest, taxes, insurance and association dues, the full monthly payment used in the denominator.
Market rent: The monthly rent an appraiser concludes a house would command, built from comparable rentals.
In-place rent: The rent a signed lease actually pays today.
Rent schedule: The appraisal exhibit that documents comparable rents and reconciles to a final market rent figure. Form 1007 covers single-family houses. Form 1025 covers 2-4 unit buildings, unit by unit.
Pool (blanket) loan: Several properties under one note, tested together. “Pool” here means a loan pool, not a swimming pool.
What Does “Portfolio Loan” Mean Here?
The term gets used three ways, and the vacant-house answer depends on which one is in play.
A blanket or pooled loan puts several properties under one note. A lender-held portfolio loan is one the lender keeps on its own books rather than selling. Per-property financing is separate loans, one per house, sometimes from one lender.
This article is about the first. On the network’s portfolio programs, a 30-year structure takes roughly 2 to 20 properties under one note, with leverage up to 80% of value on a purchase or rate-and-term refinance and coverage of 1.00 measured on the pool. A separate rental portfolio term loan covers five or more rentals, with leverage up to 75% of value. Both are program ceilings and floors, typically stated with qualifiers, never quotes, and subject to lender guidelines.
A blanket structure consolidates the loan, not the collateral analysis. Each property still gets its own appraisal and its own rent opinion.
How Is a Vacant House Counted, Step by Step?
The mechanics run the same way on most files.
1. Each house is appraised and gets its own rent opinion. The appraiser documents comparable rentals on a rent schedule. For a single-family house, that is Form 1007, where the appraiser comments on vacancy and rent trends and reconciles to a final monthly market rent.
2. Rent is chosen property by property. A leased house is usually credited at the lower of the signed lease and market rent. A vacant house has no lease to compare, so market rent stands alone. Your own projection does not set the number. The appraiser’s opinion does.
3. Each house gets a full PITIA. Principal, interest, taxes, insurance and association dues. Leave one out and the coverage looks better than the lender will see it.
4. Sum and divide. Total rent used for review goes over total PITIA. That is not the average of each house’s ratio. A few large payments can dominate the result.
5. The lender tests the pool. The pooled ratio has to clear the program floor. Lenders can also look at aggregate leverage and the weakest asset. Some programs add a per-property overlay on top, so the term sheet matters.
6. Every house still needs a lease or appraiser-supported rent. A house with neither is a gap in the file, not a free rider.
7. Who decides what. The appraiser stops at the rent opinion. The lender decides how it gets used, whether on coverage, reserves or leverage tier. Two lenders can read the same rent schedule and land in different places on leverage.
The agency forms are borrowed as a format only. Agency rental-income qualifying rules do not govern DSCR files. By contrast, FHA program rules call for an appraisal plus Form 1007 to document proposed rental income on a one-unit property. That shows market rent is a widely accepted stand-in for a tenant not yet in place, nothing more.
Which Rent Goes Into the Pool?
| Situation | Rent typically used |
|---|---|
| Leased house | Lower of lease and market rent |
| Vacant house | Appraiser’s market rent |
| 2-4 unit, mixed occupancy | Per-unit lease or market rent |
| Short-term rental | Hosting history, not Form 1007 |
Treatment varies by lender, so confirm before you build the file around it.
How Much Can One Empty House Drag the Pool?
The drag is roughly the house’s share of total payment times the gap between its ratio and the rest of the pool. Take a hypothetical weak house carrying 25% of total payment and sitting 0.50 below the others. It costs about 0.125 of pooled coverage.
The sensitivity is sharper at the extreme. Lendmire’s own worked example counts a house at a 0.00 ratio, the stress case where it earns nothing. That pulls a pool of four to about 0.975 and a pool of ten to about 1.17. Those figures are illustrative, built on assumed inputs, and not program thresholds.
| Pool size | One house at 0.00 | Read |
|---|---|---|
| Four houses | About 0.975 | Can sink the pool |
| Ten houses | About 1.17 | Barely registers |
The lesson is concentration. The same empty house sinks a small pool and hardly moves a large one. Network treatment is market rent, not zero, so the stress case is what the cure, carve-out and split options protect against.
What Gets Checked Even When the Pool Passes?
Passing the pooled test does not clear each house. The property-by-property gate covers condition, rent-readiness, occupancy and value.
Condition is the gating issue, not vacancy. A turnkey house with no tenant usually works on market rent. A gutted or mid-rehab house usually fails because it is not rentable yet. Those are the first candidates to cure, carve out or split off.
Occupancy is its own item. Vacancy does not create owner occupancy, and the borrower cannot move in during lease-up. A DSCR loan is non-owner-occupied investment financing, and owner-occupied property is ineligible in the pool.
Property type matters too. Manufactured homes, log homes and barndominiums are not offered in these programs. Mixed-use, commercial, co-op and mobile-home collateral is also ineligible in the pool.
Credit, reserves and eligibility rules still apply to a vacant house. Pool credit floors typically start around 640, with 680 or 720 on some structures, and a special-purpose entity (typically an LLC) is required on some, subject to program terms. Reserves vary by lender, leverage and loan size, and are commonly held for taxes, insurance and capital expenditures.
Keep It In, Cure It, Carve It Out, or Split It Off?
| Option | When it fits | What it changes |
|---|---|---|
| Keep it in | Turnkey house, pool clears with room | Nothing |
| Cure it | Minor work, then lease or re-rent opinion | Rent becomes supported |
| Carve it out | Pool is thin without it | Smaller pool, cleaner ratio |
| Split it off | Needs rehab or its own financing | Separate loan for that house |
A practitioner habit on pooled files: look at the weakest house first, not the average. If one house is the only thing between the pool and the floor, fix or remove it before submission. A strong pool should be able to absorb a vacancy. A thin one can’t.
What About Releases and Re-Tests Later?
Partial releases, substitutions and the sale of one property out of the pool follow the loan documents and the lender’s release terms. The release clause sets the release price, whether a fresh appraisal or coverage retest is required, and the notice period. The release price runs above the property’s allocated balance.
The practical point: the remaining portfolio must still cover its debt service. Selling the strongest house out of a pool that carries a vacant one can leave the remainder short. Read the release language before you commit to the structure.
Separate vacancy at closing from vacancy after closing. A house vacant at closing is underwritten on market rent. A tenant who leaves after closing is an operating risk, not an underwriting event. Keep reserves for it.
What If the Appraisal Rent Comes In Low?
The rent opinion caps what the house contributes, and a pro forma will not override it. Options are limited and honest:
- Request an appraisal reconsideration with comparable rental evidence the appraiser did not have.
- Check the comps before going under contract, not after.
- Lease the house at a rent the market supports, then let the lower-of rule work on a real lease.
- Accept the lower rent and see whether stronger houses carry the pool.
Rent can cap proceeds before value does. LTV and coverage are two separate tests, and either can bind first. A larger down payment can lift coverage by lowering the payment, but it never erases leverage caps, credit floors, reserve rules or property eligibility.
Where the General Rule Breaks
Purchase versus refinance. Purchases are the easy case. On refinances, some lenders prefer a lease or operating history, and some attach an underwriting condition requiring one.
On cash-out within a portfolio, leverage never exceeds 75% of pooled value, and inside the first six months of ownership the amount is capped by the seasoning rule.
2-4 unit buildings. On purchases, both property types generally qualify off appraised market rent per unit. On refinances, a multifamily building sometimes gets more flexibility when only one or two units are vacant, since occupied units show income. Form 1025 lists rent unit by unit, and the file typically needs a rent roll and leases for the occupied units.
Short-term rentals. Form 1007 documents monthly rent for single-family homes, not nightly rent or business income, as McKissock’s appraiser education explains. Converting a nightly rate and plugging it into the form is the wrong approach. Short-term rental income runs on hosting history, often about 12 months. Lendmire’s piece What Counts As Short Term Rental Income For A Lender? covers the income side.
Rent-stabilized units. Underwriting may use the legal registered rent, depending on the program.
Pooled coverage below 1.00. A house with weak coverage can sit in the pool, but the pooled coverage, leverage and terms are what underwriting tests, subject to underwriting.
What 1.00 Does and Doesn’t Tell You
A pooled ratio of 1.00 means rent covers PITIA. That is all. Select programs start there, and stronger ratios open better pricing and leverage. Clearing it is not positive cash flow. Repairs, vacancy, management, utilities and capex sit outside the calculation.
For a vacant house this gap is wider. Coverage can look fine on paper while real monthly cash is negative until the house leases. Qualification runs primarily on property-level rental income covering the payment, subject to lender guidelines.
Pre-Submission Checklist for a Pool With a Vacant House
- Appraisal with rent schedule for every house, Form 1007 for single-family, Form 1025 for 2-4 units.
- Listing history and comps for the vacant house.
- Leases for occupied houses, plus rent roll for multi-unit buildings.
- Full PITIA built for every property, association dues included.
- Entity documents if the structure requires a special-purpose entity.
- Reserves documentation.
- A read on the weakest house and a plan: keep, cure, carve out or split off.
- The release clause, read before signing.
Lendmire’s piece Non-QM DSCR vs Portfolio Lender for an $8M Acreage Rental is useful if the pool is large enough to raise that question.
Frequently Asked Questions
Is a vacant house counted at zero in a DSCR portfolio loan?
No. On the network’s convention, the appraiser’s market rent supplies the income. The house still gets its own condition and value review, and the pooled ratio is tested on all rents against all PITIA.
Can a vacant house even be in a portfolio loan?
Yes, when it is rent-ready. Vacancy alone is not disqualifying. A house with no lease and no appraiser-supported rent is a gap in the file. A mid-rehab house is usually a candidate to cure or split off.
Does my signed lease or my projection set the rent?
Neither alone. Underwriting generally caps rent at the lower of lease and market rent, and a vacant house uses market rent from the appraisal. A pro forma doesn’t set the number.
Is the pooled ratio an average of each house’s ratio?
No. It is total rent used for lender review divided by total PITIA. Larger payments carry more weight, so one big weak house moves the result more than a small one.
Does a vacant refinance work like a vacant purchase?
Not always. Purchases are the easier case. Some lenders prefer a lease or operating history on a refinance, and a few attach a lease condition. Confirm the lender’s preference before building the file.
If you are buying or refinancing rental properties and want to see how the numbers work, Lendmire can help you compare DSCR loan options based on property income, credit profile, leverage and investor goals. Tax treatment varies; consult a qualified professional.
One more point on the pool itself: the best defense against a vacant house is a pool large and strong enough that one empty house is a rounding error.
