The Quick Read: A fixed DSCR loan suits the investor who wants a known payment path on a building with uncertain HOA finances. An interest-only ARM suits the investor who needs the rent to cover a lower tested payment and has a defined exit before the rate adjusts. Non-warrantable status changes which lenders review the file. It does not decide the structure.
- Non-warrantable is an agency label. A DSCR loan is not an agency product, so the lender weighs the unit’s rent against the payment plus project risk.
- Interest-only on the network’s programs runs 120 months, caps at 75% leverage, and is reviewed on interest, taxes, insurance and dues (ITIA).
- Non-warrantable condos are typically reviewed to 75% leverage and $1,500,000 through select wholesale programs, subject to underwriting.
- HOA dues sit in the payment on both structures, so rising dues and special assessments hit the coverage number either way.
- The real risk on an IO ARM is stacking. The end of the IO window and an adjustment period can land on a building that is hard to sell or refinance.
The honest answer on who each option fits comes first. A fixed loan fits a long hold, a thin reserve cushion, and a building where the HOA budget is a question mark. An IO ARM fits a file that needs the lower tested payment to clear, a shorter hold, and an investor with deep reserves. The exit plan cannot depend on the building becoming easier to finance later. Neither choice relaxes credit, reserves, or leverage rules. Lendmire is a broker, and its wholesale network places both structures. The IO ARM column below describes published industry norms for ARMs, and the program figures come from the network’s guidelines.

Key Terms Defined
Fixed-to-ARM hybrid: A note with a fixed starting period, then a rate that adjusts. In a 7/6, the 7 is the fixed period in years and the 6 means adjustment every six months after that.
Interest-only (IO) period: A stretch of the loan where the scheduled payment covers interest only, with no principal paydown.
ITIA: Interest, taxes, insurance and association dues. Many IO programs test rent against this instead of the fully amortizing payment.
PITIA: Principal, interest, taxes, insurance and association dues. Fixed amortizing loans test rent against this.
Payment shock: The jump in the payment when the IO period ends or the rate adjusts.
What “Non-Warrantable” Actually Means for a DSCR File
Non-warrantable is a secondary-market label. Fannie Mae’s Selling Guide lists ineligible project traits such as hotel or motel operations, split ownership, commercial space allocation, and mandatory memberships. That is the contrast, and it ends there. A DSCR loan does not follow the agency checklist.
What happens on a real file: the lender asks why the project fails. The cause matters more than the label. High investor concentration blocks agency loans but is often workable on a DSCR file. Structural litigation or critical repairs can block both. Condotels run through a narrower pool of lenders.
Rent is typically set by the appraiser on the standard forms. Fannie Mae’s forms list names Form 1007 for the rent schedule and Form 1073 for an individual condo unit.
Across the wholesale network, most programs that accept non-warrantable condos cap them at 75% leverage and $1,500,000. Condotels sit in their own box: 75% on a purchase, 65% on a refinance, $1,500,000, with $250,000 cash-in-hand. All of it is subject to underwriting.
The project package is where friction lives. Expect the HOA questionnaire, budget, reserve study, master insurance certificate, litigation disclosure, and owner and investor concentration figures. An incomplete questionnaire stalls more condo files than the payment structure does.
Side-by-Side
The fixed column reflects the network’s guidelines. The IO ARM column reflects published industry norms for ARMs, with the IO terms from the network’s guidelines.
| Factor | Fixed DSCR loan | IO ARM DSCR loan |
|---|---|---|
| Rent tested against | Full PITIA | Often ITIA on the IO window |
| Payment path | Constant principal and interest | Steps up at IO end and at adjustment |
| Review basis | Property rent vs payment | Property rent vs payment |
| Documentation | Lease or appraisal rent schedule, HOA package | Same, plus ARM rider and schedule |
| Property types | 1-4 units, condos, non-warrantable | Same, with possible added overlays |
| Entity vesting | LLC welcome, subject to program terms | Same |
| Reserves | 6 months on the subject, 12 for first-time investors | Same, counted on ITIA when IO |
| Leverage | Full ladder for the loan size | IO capped at 75% |
| Main risk | Lower qualifying cushion | Reset and recast on a hard-to-sell asset |
Pricing is not on this table by design. The calculator handles it as an illustrative estimate.
When Fixed Is the Better Fit
Fixed wins when the building’s finances are the weak point. A non-warrantable condo with a thin reserve fund or a history of assessments already carries payment uncertainty through dues. A fixed note holds the interest rate and the principal-and-interest payment for the life of the loan. The only moving pieces are taxes, insurance and dues.
Fixed also fits these cases:
- A long hold. The investor plans to keep the unit through several lease cycles.
- A thin coverage cushion after amortization. If the file only clears on interest, fixed forces the honest test first.
- Exit risk on the building. If the project stays non-warrantable, the buyer pool and refinance pool stay narrow. Fixed removes the reset from that problem.
- A cash-out refinance. Interest-only helps the coverage test but not the leverage test. Cash-out runs 75% to $1,000,000 and 70% to $1,500,000 on standard collateral, and the ladder tightens above that.
Run the numbers on a modeled unit at the 1.00 benchmark with full amortization. If coverage lands near 1.00 and a dues increase would push it under, the file leans on a structure to hide the thin spot. That is a warning sign worth acting on before choosing a loan structure.
When an IO ARM Is the Better Fit
IO works when the tested payment is the obstacle and the investor has a plan. Because the network’s interest-only programs review the file on ITIA, principal drops out of the denominator and the coverage number rises on the same rent. The IO window runs 120 months on 30- and 40-year terms, with a 75% leverage cap and coverage of 0.75 or better, subject to underwriting. Coverage between 0.75 and 0.99 is a real path through select programs, with LTV and terms adjusting. Final terms follow the full file review. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
The ARM piece adds a separate trade. The leading number in a 5/6, 7/6 or 10/6 is the fixed period, not the loan term. After it, the rate becomes an index plus a margin, usually with periodic caps and a lifetime ceiling. Risk arrives at the reset, not on day one.
IO ARM fits these profiles:
- A defined short-to-mid hold. The investor expects to sell or refinance before the first adjustment.
- Deep reserves. The shortfall risk after reset is absorbed by cash, not hope.
- A coverage gap that is purely mechanical. Rent is solid, but principal pushes the ratio under the line.
- A portfolio view. Cash preserved now funds the next acquisition, provided the investor tracks every conversion date.
An IO ARM can see both events at once: principal begins and the rate adjusts. Stack several of these loans and the conversion dates cluster across the portfolio.
IO and ARM are separate choices. IO is a payment structure. ARM is a rate structure. You can have fixed IO, adjustable IO, fixed amortizing, or adjustable amortizing. Many investors blur them and then compare quotes that differ in both.
Where Condo Risk and Structure Collide
Three failure modes show up repeatedly on non-warrantable condo files.
1. Passing on IO, failing on amortization. The file clears on ITIA. Then the IO window ends and the full payment lands on the same rent. Stress-test the amortizing payment before making the offer, not after.
2. Dues and assessments in the denominator. HOA dues sit in the payment on both structures. A special assessment or a dues increase compresses coverage whether the loan is fixed or adjustable. On an IO ARM the compression stacks on top of the reset.
3. Exit liquidity. The investor plans to sell or refinance before the adjustment. But a building’s warrantability status can change, and a non-warrantable building narrows both the buyer pool and the refinance pool. An ARM that resets while the building is hard to move is the main combined risk. HOA questionnaires can surface bad news late, which is a reason to read the package before committing to a plan that depends on exit.
One practitioner habit keeps these files clean. On condo files across the network, the questionnaire and budget get pulled first, before the structure is chosen. The project package often tells you more about which structure is safe than the rent does.
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.
Short-Term Rentals on a Condo
Short-term-rental files qualify at coverage of 1.00 or higher, to $2,000,000, on documented operating history or the appraisal’s short-term-rent analysis, at 80% of gross income. They are for experienced investors and are not on the no-ratio path. Many condo associations restrict short-term use, so the project documents matter first. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income. Variable income plus a reset is a heavier load than a long-term lease plus a fixed note.
A Quick Decision Matrix
| Investor profile | Leans toward | Main risk |
|---|---|---|
| Long hold, thin reserves | Fixed | Tighter qualifying coverage |
| Short hold, deep reserves | IO ARM | Exit slips past the reset |
| Coverage short only on principal | IO, fixed or ARM | Amortizing payment at recast |
| Building with assessment history | Fixed | Dues shock on any structure |
| Multiple financed properties | Fixed or staggered resets | Clustered conversion dates |
Match the timeline too. Three dates should be checked separately: the prepayment window, the first adjustment or IO end, and the expected exit. If the exit falls after the adjustment, the ARM is no longer a short-hold tool.
The Verdict
Fixed is the default for a non-warrantable condo when the hold is long or the building’s finances are unclear. IO ARM earns its place when the tested payment is the only barrier, the exit is defined, and reserves can carry a bad reset. This is a genuine toss-up on a mid-length hold with decent reserves. The coverage math favors IO, while the building risk favors fixed. Settle it by reading the HOA package, then stress-testing the amortizing payment.

Frequently Asked Questions
Can a DSCR loan finance a non-warrantable condo at all?
Yes, through select programs in the wholesale network. Non-warrantable condos are typically reviewed to 75% leverage and $1,500,000, subject to underwriting. The lender reviews the project package, since the reason for the label matters more than the label.
Does interest-only change the leverage I can get?
Often it lowers the ceiling. Interest-only on the network’s programs caps at 75% leverage with coverage of 0.75 or better, qualified on ITIA. Choosing IO does not relax credit or reserves either. Reserves run 6 months of ITIA on the subject property, 12 for first-time investors.
Is the 7/6 or 5/6 number the loan term?
No. The first number is the fixed period in years. The note is typically 30 years, and the rate adjusts every six months after the fixed period ends.
What happens to coverage when the IO period ends?
The payment steps up as principal begins, even if the rate does not move. A file that clears on the IO payment may not clear on the amortizing one, so run that test before the offer.
Do HOA special assessments affect the coverage ratio?
Yes, on both structures. Association dues sit in the monthly obligation the rent is tested against. A dues increase compresses coverage on a fixed loan and on an ARM alike.
Is a condotel the same as a non-warrantable condo?
No. A condotel is typically non-warrantable, but the label has many other causes. In the network, condotels sit at 75% on a purchase and 65% on a refinance, to $1,500,000 with $250,000 cash-in-hand, subject to underwriting.
