The Quick Read: A DSCR lender handles new vacancies in a rental pool by counting each empty house at the appraiser’s market-rent opinion instead of a lease, then testing the pool as a whole, so stronger properties can offset weaker ones, while still reviewing each vacant property’s condition and rent-readiness on its own. A vacancy does not automatically disqualify the file. It changes the math, and sometimes the structure.
- Vacant, rent-ready houses are generally counted at appraiser-supported market rent. Leased houses are generally counted at the lower of the lease or market rent.
- On the 30-year portfolio DSCR loan, coverage is measured on pooled rent against pooled debt service, with a 1.00 floor.
- One weak property drags the blended number down, and the lender still reviews it individually.
- Your options are to keep it in, cure it, carve it out, or split the pool.
- Clearing 1.00 is not the same as positive cash flow.
What Does a Portfolio Refinance Actually Mean?
A portfolio refinance puts several rentals under one loan, or closes several loans together. The difference matters more with vacancies than almost anywhere else. One note secured by many properties tests them together. Separate loans test each house alone.
DSCR stands for debt service coverage ratio. It compares rent to PITIA, which is principal, interest, taxes, insurance, and association dues. The lender divides eligible rent by that monthly obligation. 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.
Across our wholesale network, two portfolio structures cover most of these files. Both are subject to lender guidelines.
The first is the 30-year portfolio DSCR loan:
- It covers 2 to 20 properties under one note, with loan sizes of roughly $300,000 to $5,000,000 (larger balances on review).
- Leverage runs up to 80% of value on investment-property purchases and rate-and-term refinances.
- Rate types include fixed and adjustable, and an interest-only period is available.
- Eligible property types are single-family, 2-4 unit, condo, and townhome.
- Coverage is measured on the pool.
The second is the rental portfolio term loan:
- It is built for five or more rental properties or units under one loan, with loan sizes of $500,000 to $50,000,000 (larger balances on review).
- Leverage runs up to 75% of value on investment property.
- Terms are fixed at 3, 5, 7, or 10 years with a balloon at maturity, and prepayment follows a yield-maintenance schedule.
- Recourse and non-recourse versions both exist. A non-recourse loan looks to the real estate, with carve-outs such as fraud and bankruptcy.
- Properties in several markets can sit under one loan, and small multifamily is an eligible type. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
The standard single-property DSCR loan-size range does not apply to either structure. The full picture of how these loans work sits in Lendmire’s complete DSCR loans guide.
Key Terms Defined
Market rent: the monthly rent an appraiser estimates a property would earn if leased today, supported by comparable rentals.
Rent roll: a list of every unit, its tenant status, and its current rent.
Pooled coverage: total eligible rent across all properties divided by total PITIA across all properties.
Cross-collateralization: every property in the pool secures the whole loan, not just its own share.
Release clause: the loan term that lets one property leave the pool when you sell it, usually on the lender’s price and conditions.
Rent-ready: a vacant property in livable, market-ready condition, so a tenant could move in without major work.
How Does the Lender Count Each Property?
Each property gets its own rent figure, and the pool ratio is built from those figures. Vacant and leased houses are treated differently, but neither is ignored.
The income input starts with the appraisal. For one-unit properties, the appraiser’s rent schedule is the standard single-family comparable rent schedule form. It carries an indicated monthly market rent line. It also asks the appraiser to comment on the local rent range, estimated rental vacancy, and the trend in rents and vacancy. For 2-4 unit properties, the report is Form 1025, which carries rent unit by unit.
These forms are borrowed from the conventional world. DSCR loans are not governed by that world’s rules. Fannie Mae’s appraiser guidance for one-unit investment properties describes the rent schedule as a tool for documenting monthly market rent. It is not built for nightly-rate projections, so short-term rentals run on a different track.
| Property status | Typical rent input | What helps |
|---|---|---|
| Leased at market | Lease, capped at market | Signed lease, deposit record |
| Leased above market | Market rent, usually | Appraisal comps |
| Leased below market | The lease | Lease-up at renewal |
| Month-to-month or expired | Generally market rent | Rent roll, payment history |
| Vacant and rent-ready | Market rent | Photos, listing, rent comps |
| Under renovation | Not eligible as-is | Finish work first |
A high lease rarely boosts the ratio, because the lender generally uses the lower of the lease or market rent. Each property still needs a lease or an appraiser-supported market rent. Consolidating the loan does not skip valuation, so every house gets its own appraisal and rent schedule.
How One Vacancy Moves the Pooled Ratio
A vacancy moves the pooled ratio by the gap between that house’s coverage and the pool’s average, divided by the number of properties. Small pools feel it hard. Large pools absorb it.
Run the numbers on a modeled four-house pool. Assume equal debt service on each house. Three houses cover at 1.30, 1.25, and 1.20. The fourth just lost its tenant.
| Scenario | Pool size | Vacant house counted at | Pooled coverage |
|---|---|---|---|
| Market-rent credit | 4 houses | 0.80 | About 1.14 |
| Leased-only counting | 4 houses | 0.00 | About 0.94 |
| Market-rent credit | 10 houses | 0.80 | About 1.16 |
| Leased-only counting | 10 houses | 0.00 | About 1.08 |
The ten-house line assumes nine houses at 1.20 and one vacant house, again with equal debt service. These are modeled assumptions, not market data.
The takeaway is the treatment, not the size. Counting the empty house at market rent keeps the small pool above 1.00. Counting it at zero drops that pool to roughly 0.94, under the pooled floor on the 30-year portfolio DSCR loan. A rental below 1.00 can sit in the pool, but only when the pooled coverage, the leverage, and the terms hold up under underwriting, subject to underwriting.
Files with several vacancies at once rarely fail on one house. They fail because three houses share the same problem, such as a seasonal gap or a local rent reset. Then the pool has no stronger property left to carry the weaker ones.
Keep It, Cure It, Carve It Out, or Split the Pool
Each vacant property has four paths, and the right one depends on its condition and the pool’s cushion. The decision is yours, but underwriting shapes what is available.
| Option | Choose this when | Trade-off |
|---|---|---|
| Keep it in | Rent-ready, pool clears with room | Pool carries the weaker house |
| Cure it | Light work or lease-up is near | Delays the application |
| Carve it out | One house drags the ratio | Refinance it later, separately |
| Split the pool | Two groups with different strengths | More than one closing |
Curing means finishing the work, listing the house, or signing a tenant before you apply. A signed lease only helps if it holds up against market rent, since the lender generally uses the lower figure. Curing a rehab matters most, because properties needing structural or major work are generally not eligible as-is. That is why investors often use a short-term bridge loan first, then refinance once the house is rent-ready.
Carving out is the cleanest fix for a problem house. Splitting suits a mixed portfolio. A strong group can go to the term loan, while a smaller group sits on separate loans. With separate loans, a vacant house must qualify alone, but it cannot drag the others. Watch for dragnet or cross-default language, though.
How the Lender Works the File, Step by Step
The lender’s workflow runs in the same order on almost every portfolio file. The vacancy checkpoints sit at steps one, two, and five.
1. Intake and sort. Each property is tagged leased, vacant but rent-ready, or under renovation. You supply leases, a rent roll, and unit status, plus concessions and collections where they apply.
2. Appraisals ordered. Each house gets its own appraisal and rent schedule. Vacant houses get market rent only.
3. Rent assigned per property. Vacant means market rent. Leased generally means the lower of lease and market.
4. Pool test. Total eligible rent is divided by total PITIA across the pool.
5. Property-by-property review. Even when the pool clears, condition, occupancy, and value are checked individually. A vacant house is the first candidate to cure or carve out.
6. Entity and credit review. The credit floor is typically 640, rising to 680 or 720 on some portfolio structures. A special-purpose entity, usually an LLC, is required on some structures, subject to program terms.
7. Structure and release terms set. Partial releases, substitutions, and sales out of the pool follow the loan documents. The remaining portfolio must still cover its debt service.
Every program has its own tolerance for vacancy. Across our network, some lenders are comfortable with one or two vacant houses in a larger pool. Others want a lease or operating history on every refinanced property. Ask before you apply, because a refinance is often treated differently from a purchase.
Where the General Rule Breaks
The market-rent rule is the general rule. These edge cases are where it bends.
- Purchase versus refinance. Vacancy on a purchase is routine. On a refinance, some lenders want a lease or an operating history.
- Long vacancy. A house that sat empty for a long stretch invites questions about marketability and occupancy history. Listing records, rent comps, and a signed lease answer those questions.
- Vacancy and other terms. A vacancy can also shift leverage, reserves, and appraisal review, not only the ratio.
- Short-term rentals. Short-term rental collateral follows its own purchase, refinance, and cash-out leverage limits. It needs a hosting history, not just a monthly rent schedule.
- Ineligible property types. Owner-occupied property, mobile homes, co-ops, mixed-use, and commercial property are ineligible in the pool. Manufactured homes, log homes, and barndominiums are not offered in the network’s DSCR programs.
The biggest edge case runs after closing. With one note, every property secures the whole loan. As Corporate Finance Institute explains, selling a pledged asset may require repaying all the debt it supports unless the lender consents to alternatives. Default also raises the risk of losing the asset. Release terms are negotiated lender by lender. The release price runs above the property’s allocated balance, so plan for a larger paydown than a simple per-house share.
What Changes on a Cash-Out Refinance?
Cash-out proceeds on a portfolio loan never exceed 75% of the pooled value on seasoned investment properties, and the structure’s own ceiling can bind first. Short-term-rental collateral has its own lower cash-out ceiling.
Vacancy makes cash-out tighter. In the first six months of ownership, a cost-based cap limits how much you can take out. A rate-and-term refinance carries no such cost restriction.
Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
Timing matters here too. For vacancies, the practical rule is simple. Lease first, then pull cash.
Stress-Test Your Own Pool Before You Apply
Run four checks yourself before a lender does.
1. Two vacancies at once. Drop two houses to market rent and see whether the pool still clears.
2. A rent dip. Lower every rent a notch and recheck the blended ratio.
3. A repair shock. Imagine your weakest house needs work and has to come out. Does the rest of the pool hold?
4. Zero credit. Count your vacant house at nothing. That is your worst case.
The most common mistakes follow from skipping these checks. Investors count a vacant house at last year’s rent instead of today’s appraisal. They bundle a rehab into a pool of rent-ready houses. They ignore release terms until a sale is already under contract. And they confuse the coverage test with cash flow.
That last one matters. DSCR compares rent to PITIA only. A pool that clears 1.00 can still lose money month to month, because repairs, vacancy loss, management, utilities, and capital expenses sit outside the calculation. The strongest files clear two tests, enough equity and enough rental coverage.

Frequently Asked Questions
Does one vacant house disqualify a portfolio refinance?
Not on its own. A rent-ready vacant house is generally counted at appraiser-supported market rent, and the pool is tested as a whole. The house is still reviewed individually for condition and value, so it may be cured, carved out, or kept in depending on the cushion.
Can I include a house that is under renovation?
Usually not as-is. Properties needing structural or major work are generally not eligible until they are rent-ready. Finish the work first, or carve that house out and refinance it later on its own.
Do I need a lease for every property?
No, but every property needs either a lease or an appraiser-supported market rent. On a leased house the lender generally uses the lower of the lease and market rent. A high lease does not lift the ratio.
Is a blanket loan or separate loans better with vacancies?
Separate loans keep a vacant house from dragging the others, though the vacant house must qualify alone. A single note gives you one closing and blended coverage, but it ties every property together and makes release terms matter. Both depend on lender guidelines and the pool’s cushion.
Does clearing 1.00 mean the portfolio is cash-flow positive?
No. The coverage test counts rent against PITIA only. Repairs, vacancy loss, management, utilities, and capital expenses are outside it, so budget for them separately.
