The Quick Read: No, DSCR loans are not all adjustable, and the 30-year fixed is the spine of the programs most investors use, with adjustable-rate (ARM) structures offered as an alternative for investors who want a lower starting payment and a defined hold.
- Fixed is the default. Across a wholesale lending network, the 30-year fixed is the structure most files are built around.
- Most adjustable loans start fixed. A hybrid ARM holds its rate steady for an initial period, then resets.
- Interest-only is a payment feature. Select lenders in the network offer it on both fixed and adjustable structures.
- Longer terms exist. A 40-year term is available through select lenders, and loans above $2,500,000 generally stay with 30-year fixed structures.
- Your plan picks the structure. Hold period, exit strategy, and tolerance for payment change matter more than any rule of thumb.
Where Does the “All Adjustable” Idea Come From?
Three things get blended together in investor conversations. They are fixed-rate loans, hybrid ARMs, and interest-only periods. Each one changes the monthly payment in a different way, and people often treat them as one thing.

A DSCR loan (debt service coverage ratio loan) qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Because it is built around the property and not your paycheck, people assume it must be a different animal in every way. It isn’t. The rate structure works like it does on other mortgages.
Here are the pieces that get mixed up:
- Fully fixed: The rate never changes for the whole term.
- Hybrid ARM: The rate is fixed for several years, then adjusts on a schedule.
- Interest-only period: You pay only interest for a set stretch. The rate can still be fixed. The payment changes later because principal begins.
A payment that rises after an interest-only period can feel like an adjustable rate. It isn’t one. The rate stayed the same and the loan simply began paying down principal.
What Does a Fixed DSCR Loan Look Like?
A fixed DSCR loan locks the interest rate for the full term, and the term is usually 30 years. Your principal and interest payment stays the same for as long as the loan runs. Taxes and insurance can still move, but the loan itself does not.
This is the structure we place most often. Most programs across our wholesale network build their guidelines around it. The standard purchase tiers on an investment property typically sit at 75%-80% LTV (loan-to-value, the loan as a percentage of the property’s value). Select high-leverage programs can reach 85% LTV on a purchase with a stronger credit score, roughly 700 or higher. All of this is subject to lender guidelines, and every file is underwritten individually.
Fixed suits investors with these goals:
- A long hold, where payment stability matters more than the lowest starting cost.
- A thin margin, where a payment increase would hurt.
- A portfolio where the investor wants the debt side to be the predictable part.
The tradeoff is cost at the start. An ARM typically starts out cheaper than a comparable fixed loan, so the fixed payment is often higher in the early years. You are paying for certainty.
Fixed also doesn’t mean free to leave. Prepayment penalties are a separate feature, and they show up on fixed and adjustable loans alike. A common structure is a step-down schedule such as 5-4-3-2-1, where the penalty percentage drops each year. Lenders often trade a longer or heavier penalty for better pricing. Fewer penalties usually cost more at the start.
How Does a Hybrid ARM Work?
A hybrid ARM keeps the rate fixed for an initial period, then lets it adjust on a schedule. Nothing floats from day one. An investor who takes a five-year hybrid ARM has five years of a fixed rate before the first change.
Reading the notation
The shorthand tells you two things. The first number is how many years the rate stays fixed. The second number is how often it adjusts after that.
- 5/1: Fixed for five years, then adjusts every year.
- 7/6: Fixed for seven years, then adjusts every six months.
A 5/1 and a 5/6 sound nearly identical, but they reset at different frequencies. Confirm the actual terms in the loan documents rather than trusting the label.
Index plus margin
After the fixed period, the new rate is built from two parts. The index is a market benchmark, such as SOFR. The margin is a fixed number set when the loan is made. The CFPB explains the basic formula for adjustable-rate mortgages generally: index plus margin equals your interest rate, subject to any rate caps. It also notes that the margin is set in the loan agreement and doesn’t change after closing.
One caution on that source. The CFPB’s consumer handbook on ARMs is written for consumer mortgages. DSCR loans are business-purpose investor loans, and consumer disclosure rules don’t govern them. Your note and loan documents control the terms, so read those line by line.
Caps and floors
Adjustments are usually bounded. Lenders set limits on how much the rate can move at the first reset, at each later reset, and over the life of the loan. Cap structures vary by program, so don’t assume any one set of numbers applies to your loan.
Many ARMs also carry a floor, often the starting rate. That means a falling market may not lower your payment. The downside is capped but the upside may be too, so ask about the floor before you assume falling rates will help you.
What happens at the reset
Pricing and available terms vary by lender, borrower profile, property type, and full underwriting review. If the index has risen, so does your payment. If it has fallen, the floor may hold you where you were.
Refinancing before the reset is a common plan among investors, but it carries a risk: the market, the property’s rents, or your own credit may look different when you need the new loan. Lendmire’s piece Refinancing an Adjustable Mortgage Into a Fixed Payment Before the Reset walks through that exit.
Fixed vs. Adjustable, Side by Side
| Factor | Fixed DSCR Loan | Hybrid ARM DSCR Loan |
|---|---|---|
| Rate during term | Locked for full term | Locked, then resets |
| Starting payment | Usually higher | Usually lower |
| Payment certainty | High | High until reset, then varies |
| Best hold period | Long | Shorter or defined |
| Refinance dependence | Low | Higher if you plan to exit before reset |
| Prepayment penalty | Possible | Possible |
The row that matters most is refinance dependence. A fixed loan has no cliff. An ARM has a date on the calendar, and your plan should be built around it.
What Decides Which Structure You Can Get?
Availability varies by lender, and it doesn’t follow one universal rule. The common drivers are the lender’s program menu, the loan size, the property, and the structure you want to add.
This is where a broker with access to many lenders earns its keep. A single lender may only offer the 30-year fixed. Another may offer the fixed plus an ARM. Select lenders in our network add 40-year terms and interest-only periods. Above $2,500,000, the network generally holds to 30-year fixed structures, so a larger balance narrows the menu.
The usual file requirements still apply whichever structure you choose. Most programs want a credit score around 660, a 620 floor exists in parts of the network, and 700 or higher opens the strongest leverage tiers. Reserves are commonly around 6 months of PITIA (principal, interest, taxes, insurance, and any association dues), and they step up to about 9 months on loans above $1,500,000. Conservative rate-and-term files at modest leverage under that size can see reserves waived. The complete DSCR loans guide covers the full qualification picture.
Manufactured homes (single- and double-wide), log homes, and barndominiums are not offered through the network’s DSCR programs. Rate structure doesn’t change that.
Does the Rate Structure Change Your DSCR?
It can. DSCR is monthly rent divided by the monthly housing payment, which is PITIA. A lower starting payment raises the ratio. A property that clears 1.00 on an ARM’s starting payment may sit lower on a fixed payment.
Lenders handle the testing differently. Some test the ratio at the starting payment. Others use a different qualifying payment for adjustable loans. Ask which payment the lender will test before you pick a structure around the ratio.
Coverage of 1.00 is where many select programs start, not a universal standard. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger ratios generally open better pricing and leverage.
A passing ratio also isn’t the same as positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation, and they hit the ARM investor and the fixed investor alike.
DSCR vs. conventional financing
There are two common ways to finance an investment property, and they qualify you differently — here’s how investors weigh them.
Why investors choose it
- Qualifies on the property’s rental income — no personal tax returns, W-2s, or pay stubs needed to document income.
- No personal debt-to-income ceiling to clear, so existing mortgages and obligations don’t cap your borrowing the same way.
- Can be closed in an LLC, keeping the property inside a business entity.
- Built for scaling — not held to the limit on number of financed properties that conventional financing applies.
- Underwriting centers on the deal: generally qualifies when the rent covers the payment, a 1.00x coverage ratio being a common baseline (confirmed in underwriting).
- Designed specifically for investment property, including long-term and, where the program allows, short-term rentals.
Where it’s strong
- Often the lowest ongoing financing cost for a buyer who fully qualifies on personal income — a fit for a first property or a cost-first purchase.
Trade-offs for investors
- Requires full personal income documentation and must fit within a debt-to-income limit — salary, existing debts, and other mortgages all count.
- Typically held in your personal name rather than a business entity.
- Caps how many financed properties you can carry, which can become a ceiling as a portfolio grows.
- Evaluates you as a borrower as much as the property, which usually means more paperwork.
How investors usually choose: a first or single property often optimizes for the lowest financing cost; portfolio builders often optimize for leverage, vesting in an LLC, and scaling past conventional caps. The right answer depends on your goals, the property, and current guidelines — both paths run through select lenders in Lendmire’s wholesale network, with eligibility and terms confirmed in underwriting.
How Do You Choose?
Start with your hold period, because it settles more than any rate comparison. Then test the plan against what could go wrong.
Run the numbers on two investors with the same property.
Investor one plans to sell in about four years. A five-year hybrid ARM covers the whole hold. The lower starting payment lifts the coverage ratio, and the first reset never arrives. This is the case where an ARM is a reasonable fit.
Investor two plans to keep the property for a decade. The ARM would reset several times during that hold. If the rent covers the payment at roughly 1.10x on the fixed structure, there is little cushion for a payment jump. A fixed loan removes that question.
A third case sits in the middle. Say a plan calls for renovating and refinancing in three years. An ARM fits the timeline. But the refinance depends on appraisal and rents at that point, so the investor should keep cash reserves and a backup plan.
A simple test helps. Ask what happens if the exit slips by a year. If the answer is “I’d be fine,” an ARM may work. If the answer is “the deal breaks,” choose fixed.
Is Interest-Only the Same as Adjustable?
You can have a fixed-rate loan with an interest-only period, or an adjustable loan with one.
On a 30-year loan with a 10-year interest-only period, the balance starts paying down only after year ten. The payment steps up then, even though the fixed rate hasn’t moved. An interest-only period is partial, and it doesn’t last the whole term.
Combining interest-only with an ARM adds two sources of payment change: the rate reset and the later principal start. Select lenders in the network offer interest-only periods, so ask whether a given structure carries both risks and when each one hits.
Questions to Ask a Lender
Bring this list to any loan conversation:
- Is the loan fully fixed, or does the rate reset? When?
- If it adjusts, what is the index, the margin, and the adjustment frequency?
- What are the first-adjustment, periodic, and lifetime caps?
- Is there a rate floor?
- Which payment is used to test my DSCR?
- Is there an interest-only period, and when does principal begin?
- What is the prepayment penalty schedule, and how does it interact with my exit plan?
Can You Mix Structures Across a Portfolio?
Yes. Many investors hold fixed loans on long-term keepers and shorter-term adjustable loans on properties they plan to sell or refinance. The benefit is balance. The risk is that adjustment dates can cluster, so several loans may reset in the same year.
Staggering the dates, or keeping your longest holds on fixed loans, limits that exposure. Track every reset date and every prepayment schedule in one place.
Tax treatment varies; consult a qualified professional.

Frequently Asked Questions
Are all DSCR loans adjustable?
No. The 30-year fixed is the structure most programs are built around. Adjustable options exist for investors who prefer a lower starting payment, and availability depends on the lender.
Can I get a 30-year fixed DSCR loan?
Yes, on most files. It is the structure we place most often, subject to lender guidelines, credit, property review, and loan size. Above $2,500,000, the network generally holds to 30-year fixed structures.
What does the first number in an ARM mean?
It is the number of years the rate stays fixed. In a 7/6, the rate is fixed for seven years and then adjusts every six months. In a 5/1, it is fixed for five years and then adjusts once a year.
Can an ARM rate keep rising without limit?
Usually not. Adjustable loans carry caps that limit how much the rate can change at each reset and over the life of the loan. The exact caps depend on the program, so confirm them before you commit.
Can I refinance before the first reset?
Often, but it isn’t certain. The new loan depends on your credit, the property’s rents and value, and the program’s requirements at that point. Check the prepayment penalty schedule so you know what an early exit would cost.
