The Quick Read: Fixed fits the investor who plans to hold the pool for years, and adjustable fits the investor who expects to sell or refinance before the first reset. Both sit on the same underwriting: the pool qualifies primarily on rental income covering the debt service, subject to lender guidelines. The structure you pick decides how that coverage behaves after closing.
- On the 30-year portfolio DSCR loan, both fixed and adjustable structures exist. The rental portfolio term loan is fixed-term with a balloon at maturity.
- Coverage is measured on the pooled rent against pooled debt service, so stronger properties can offset weaker ones.
- Geographic spread does not spread reset risk, because one index moves every adjustable loan at once.
- Mixed structures are only possible with separate loans, not inside one note.
- A fixed structure with a balloon still ends in a refinance or a sale.
Across Lendmire’s wholesale network, the fixed-versus-adjustable question is a central one on multi-market files. The answer depends less on the structure itself than on hold period, pool design, and the exit.
Side-by-Side
Fixed and adjustable differ mainly in how the note behaves over time. The review basis is the same. The table shows published industry norms alongside the network’s portfolio structures.
| Factor | Fixed | Adjustable |
|---|---|---|
| Review basis | Pooled rent vs. pooled debt service | Same pooled test |
| Documentation | Entity papers, guarantor credit, leases or market rent | Same file |
| Property types | SFR, 2-4 unit, condo, townhome | Same |
| Entity vesting | Usually an LLC; common on both | Same |
| Tested debt service | The note’s own schedule | Varies by program; may differ from the starting schedule |
| Reset exposure | None inside the fixed term | Pool-wide at each adjustment |
| Reserves | Vary by lender, leverage and size | Same, sometimes stricter |
| Exit planning | Hold, sell, or refinance at maturity | Refinance or sell before the reset |
Two details matter here. First, the tested debt service on an adjustable loan can differ by program. Some programs test at the starting schedule, and others test at a stressed one. Interest-only periods change the test again, because coverage on interest-only debt service reads differently than on a fully amortized schedule.
Second, DSCR compares rent to PITIA only. Clearing 1.00 is not the same as positive cash flow. Repairs, vacancy, management, utilities, and capital expenses all sit outside the ratio.
What the Network’s Portfolio Structures Look Like
A portfolio DSCR loan is one note secured by several rentals. “Blanket loan” and “cross-collateralized loan” name the same thing. (A bank’s portfolio loan, meaning a loan the bank keeps on its books, is a different use of the word.)
Lendmire arranges two structures through its wholesale network:
- The 30-year portfolio DSCR loan covers two to 20 properties under one note. Balances run from $300,000 to $5,000,000, with larger sizes on review. Leverage goes up to 80% on a purchase and on a rate-and-term refinance. It offers fixed and adjustable structures, a 30-year term, and an interest-only period.
- The rental portfolio term loan covers five or more rental properties or units under one loan. Balances run from $500,000 to $50,000,000, with larger sizes on review. Leverage goes up to 75%. Terms are fixed at 3, 5, 7, or 10 years with a balloon at maturity. Recourse and non-recourse versions exist, and it is the only structure that takes small multifamily of five or more units.
Both are subject to lender guidelines. Credit floors start at 640, and some portfolio structures want 680 or 720. A special-purpose entity, typically an LLC, is required on some structures. Recourse loans carry a personal guarantee.
Several property types are not eligible in a pool. Owner-occupied homes, co-ops, mixed-use property, and commercial property are out. Manufactured and mobile homes are not reviewable on these programs.
Every property still needs a lease or an appraiser-supported market rent. A rental below 1.00 coverage can sit in the pool when underwriting tests the pooled coverage, the leverage, and the terms.
When Fixed Is the Better Fit
Fixed is the better fit when the pool is a long-term hold and the investor values a payment that stays put. That is the cleanest case across a multi-market portfolio, where rents move at different speeds in different places.
Consider an investor with a dozen rentals spread across several metros. Some markets see rent growth and others flatten. A fixed structure makes the debt side of the ratio a known quantity. The investor only has to watch the rent side.
Fixed also suits investors who underwrite conservatively. If the pool clears the floor with thin room, a payment that cannot move removes one variable. Thin coverage and an adjustable note compound each other.
The catch is that fixed does not mean refinance-free. On the rental portfolio term loan, the 3-, 5-, 7-, or 10-year term ends in a balloon. The investor refinances or sells at maturity, so the exit risk moves from a reset date to a maturity date.
Prepayment terms matter too. On that term loan, prepayment follows yield maintenance. The schedule runs 54 months on the 5-year note and 114 months on the 10-year note. An investor who may sell a property early should weigh that against the benefit of a longer fixed term.
Fixed also tends to be the more forgiving choice if the investor is unsure of the hold. An investor who guesses wrong on a fixed note faces a prepayment question. One who guesses wrong on an adjustable note faces a payment question and a refinance question at once.
When Adjustable Is the Better Fit
Adjustable is the better fit when the investor has a defined exit before or near the first reset. Typical cases are a planned sale, a stabilization plan followed by a refinance, or a pool that will be restructured.
On the 30-year portfolio DSCR loan, an adjustable option sits next to the fixed one. The appeal is an initial period that suits a shorter plan. The risk is what happens if the plan slips.
Here is how the mechanics work, per the CFPB’s explanation of ARM index and margin. When the initial period ends, the index and the margin are added together to set the new rate, subject to caps. The index moves with the market. The margin is set in the loan agreement and does not change after closing. Those mechanics are written for consumer loans, but the same index-plus-margin logic is how adjustable notes generally work. The CFPB also notes that adjustments follow the market, not the borrower’s personal finances.
Caps limit how fast a payment can rise. They do not promise the properties still cover the new debt service. Coverage is typically tested at origination, not at each reset.
Run the numbers on a hypothetical pool. Say the pool clears the floor at roughly 1.25x at closing. After a reset, the debt service rises and the pooled ratio slides toward 1.10x. Nothing breaks, but the cushion has thinned. If one market also softens in vacancy, the pool can reach the floor even though no one property failed. This example is illustrative, not a quote.
The multi-market twist is worth stating plainly. Spreading properties across metros diversifies local rent risk. It does not diversify reset risk. A single index drives every adjustable loan, so several adjustable notes with similar reset dates move together.
An interest-only period adds a wrinkle. Coverage on interest-only debt service can look stronger at underwriting. The investor should model what coverage looks like once amortization begins, and ask whether the payment can rise during the interest-only period itself.
Pool or Separate Loans? The Structure Question Often Matters More
For investors with properties in several markets, the pool design can matter more than the fixed-or-adjustable choice. A pool puts everything under one maturity and one set of terms. Separate loans can differ in structure, term, and maturity.
That difference drives three points:
1. Mixing structures. Fixed on long holds and adjustable on planned sales is possible only with separate loans. A single note carries one structure.
2. Cross-collateral exposure. In a pool, every property backs the one note. A reset or a soft market in one place affects the whole.
3. Releases. Partial releases, substitutions, and the sale of one property follow the loan documents and the lender’s release terms. The release price runs above the property’s allocated balance, and the remaining portfolio must still cover its debt service.
Pools bring real advantages as well. Pooled coverage lets stronger properties offset weaker ones, and the investor manages one note instead of many. On the rental portfolio term loan, properties in several markets or states may sit under one loan.
A Quick Decision Map
| Investor profile | Hold plan | Likely fit |
|---|---|---|
| Long-term holder, several markets | Years, no set exit | Fixed pool |
| Value-add investor | Sell or refinance soon | Adjustable pool, or separate loans |
| Mixed hold plans across properties | Varies by property | Separate loans, or several smaller pools |
| Thin pooled coverage | Any | Fixed, or a smaller pool |
These are starting points, not rules. A pool with a real stabilization plan can make an adjustable note sensible even when the investor intends to keep the assets. The reverse also holds: a short plan with an uncertain refinance market can favor fixed.
The Refinance Dependency
Every adjustable choice quietly assumes a refinance later. Three things can block it:
- Prepayment terms. Exiting early may carry a cost, depending on the note.
- Valuation. If values drop, the refinance may not support the old balance.
- Pool mechanics. Refinancing a cross-collateralized pool may require taking out the whole pool, not one property.
Cash-out on a pool never goes above 75% of the pooled value. Inside the first six months of ownership the loan is also capped at 90% of total cost (purchase price plus documented improvements). From six to twelve months the cap is 100% of total cost. 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 Short Note on Why the Consumer Rules Don’t Apply
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. The Federal Register’s ability-to-repay rule states that business-purpose loans are outside the consumer ability-to-repay provisions. In practice, the caps and index terms on a DSCR note are set by the note and the program, not by a standard consumer disclosure. Read the note itself.
Key Terms Defined
Pooled coverage: total rent across the pool divided by total debt service across the pool.
Cross-collateralization: every property in the pool backs the same loan.
Reset: the date an adjustable note’s payment is recalculated from the index plus the margin.
Balloon: the unpaid balance due at the end of a fixed term, which the investor refinances or pays from a sale.
Yield maintenance: a prepayment charge that compensates the lender for early payoff.
Special-purpose entity: an entity, typically an LLC, formed to hold the properties, subject to program terms.
The Balanced Verdict
Neither structure wins in the abstract. Fixed gives the investor a known debt side and suits long holds and thin coverage. Adjustable suits defined, near-term exits and investors with real cushion to absorb a reset.
Pool design usually decides the question before rate type does. If hold plans differ across the properties, separate loans or several smaller pools may serve better than one note. If the investor wants one maturity and one relationship, a pool is cleaner. Either way, the investor should stress-test the exit, not just the starting coverage.
Frequently Asked Questions
Can one portfolio loan cover properties in several markets?
Yes, on the rental portfolio term loan, properties in several markets or states may sit under one loan, subject to lender guidelines. Each property still needs a lease or appraiser-supported market rent, and the pooled coverage and leverage are tested together.
Are portfolio DSCR loans fixed or adjustable?
Both exist. The 30-year portfolio DSCR loan offers fixed and adjustable structures. The rental portfolio term loan is fixed for 3, 5, 7, or 10 years with a balloon. Availability varies by lender and program.
What happens to my coverage if the payment resets?
The pooled ratio falls as debt service rises. Caps limit the pace of increases but do not guarantee the pool still covers its debt service. Coverage is typically tested at origination, so the investor should model the reset in advance.
Can I mix fixed and adjustable across my properties?
Only with separate loans. A single pooled note carries one structure, so mixing means splitting the portfolio into more than one loan. That also lets each loan have its own term and maturity.
Is a pool or separate loans better for a multi-market investor?
It depends on hold plans and exit flexibility. A pool offers pooled coverage and one note, while separate loans offer cleaner releases and structure choices.
