The Quick Read: It depends on the program, not the condo: being non-warrantable does not change the DSCR formula, but it decides whether interest-only is offered at all, and the test only helps when the lender qualifies the file on the interest-only payment (interest, taxes, insurance and dues) instead of the fully amortizing payment. Across Lendmire’s wholesale network, select programs qualify interest-only files on that interest-only payment, and non-warrantable condos run to 75% and $1,500,000 on an investment property, subject to underwriting.
- Interest-only helps the coverage ratio only when the lender tests the interest-only payment.
- Non-warrantable status changes eligibility, leverage, reserves and pricing, not the formula.
- HOA dues sit in the payment on both tests, so heavy dues shrink the interest-only benefit.
- Most investors miss the exit: the payment steps up after the interest-only window, and fewer lenders will refinance or buy these units.
Two Separate Questions Hiding in One
Eligibility and payment testing are independent decisions. First, will the program finance this condo project at all? Second, if it will, which payment goes in the denominator? A file can pass the first and miss on the second.

Short-term rental figures are estimates only and vary significantly by season, property type, management approach, and local short-term-rental rules — confirm local regulations before relying on them. Qualifying income for short-term rentals varies by program — some use appraisal market rent, others use documented STR history or projections — and is confirmed in underwriting. Not a Loan Estimate, approval, or commitment to lend. Program availability and eligibility are subject to lender guidelines, credit approval, property review, and underwriting.
Most investors blend the two. They hear that non-warrantable condos need specialty financing and assume interest-only is either automatic or off the table. Neither is true. On files we place across the network, the project review comes first. The payment test comes after, and it follows the program’s own rules.
The DSCR formula never changes. It is monthly rent divided by the payment the lender tests. What changes is the payment. For the broader mechanics, Lendmire’s complete DSCR loans guide covers the full qualification model.
What Makes a Condo Non-Warrantable
A non-warrantable condo is a project that fails the agency standards for purchase and securitization. It is a label on the building, not a flaw in the unit and not a mark against the borrower. Enact’s education blog defines it the same way: a condo that does not meet the eligibility rules of the two big mortgage agencies.
Fannie Mae’s Condo Status Finder FAQ lists the common triggers. The table below shows how each one tends to touch a DSCR file.
| Trigger | Why it matters | Touches payment test? |
|---|---|---|
| Critical repairs | Project safety and budget risk | No, eligibility only |
| Inadequate insurance | Coverage gap on the building | Can raise dues |
| Pending litigation | Possible assessments | Can raise dues |
| Hotel or short-term rental operation | Different income basis | Often changes rent basis |
One trigger is enough. A building does not need to fail several tests to land in the non-warrantable bucket.
Agency standards define the label. They do not approve or decline a DSCR loan. Each DSCR program applies its own project review, so the same building can pass at one program and fail at another. That is the main reason lender selection matters more on condos than on single-family rentals.
How Interest-Only Changes the Coverage Number
Interest-only removes the principal line from the payment. A fully amortizing payment is PITIA: principal, interest, taxes, insurance and association dues. An interest-only payment is ITIA, the same stack without principal. Rent stays the same, the denominator gets smaller, and the ratio goes up.
That only matters if the lender tests the smaller payment. Practice splits into two camps across the programs we see.
| Approach | Payment in the denominator | Effect of IO |
|---|---|---|
| IO-tested program | ITIA | Raises the ratio |
| Amortized-tested program | PITIA | Helps cash flow only |
In the first camp, the borrower pays interest-only and is reviewed on interest-only. In the second, the borrower pays interest-only but qualifies as if the loan were amortizing. The second camp helps monthly cash flow after closing. It does nothing for qualification.
The select programs in Lendmire’s network that offer a 120-month interest-only period on 30- and 40-year terms qualify the file on ITIA. They cap interest-only at 75% on an investment property, subject to underwriting. Always ask which camp a program sits in before you run the numbers.
Interest-only does not relax the other rules. Credit, reserves and leverage still apply. Credit starts at a 660 floor on most files, and reserves run six months on the subject property, counted as ITIA on interest-only loans. First-time investors typically need twelve months. Those figures are subject to underwriting and program terms.
The Same Condo, Run Twice
Run the numbers on one modeled condo, with the inputs labeled as assumptions and not market data. Say rent covers the fully amortizing payment at roughly 0.95x. That is below the 1.00 benchmark most standard programs are built around.
Switch the same file to a program that tests ITIA. With principal out of the denominator, the ratio moves to roughly 1.1x on a condo with modest dues. That is the case where interest-only changes the answer.
Now add heavy dues. Dues sit in both versions of the payment. Principal is the only piece that disappears. On a condo where dues are a large share of the monthly obligation, the same switch moves the ratio from roughly 0.95x to only about 1.05x. The benefit is real but smaller, and it can shrink further if a special assessment lifts the dues.
Sub-1.00 files have other paths. Some select lenders in the network review coverage below 1.00, but LTV and terms adjust, subject to underwriting. A lender may also review an interest-only restructure or a larger down payment. None of these is a promise. Each is a structure a lender would review against credit, reserves and the project.
Ask the association for current dues and any pending assessments before you write the offer. They move the ratio more than most investors expect.
Where Programs Differ
Some programs offer interest-only on warrantable property. Others offer it on non-warrantable condos but cut the maximum leverage. A few treat the two features as stacked limits, so the non-warrantable cap and the interest-only cap both apply and the lower one controls. No neutral source publishes a typical split, so treat this as a program-by-program question.
Before relying on any ratio, confirm these items with the lender or broker:
1. Does the program offer interest-only on a non-warrantable condo, or only on warrantable property?
2. Which payment is tested for coverage: ITIA or PITIA?
3. What are the maximum leverage and loan amount once both features apply?
4. What project documents are required: HOA questionnaire, budget, insurance certificate, litigation disclosure?
5. Which rent basis does the program use: lease, market rent from the appraisal, or an operating history?
Rent comes from the appraisal or the lease, depending on the program. Appraisers use the individual condominium unit report, Form 1073, and the single-family comparable rent schedule, Form 1007, which Fannie Mae’s Selling Guide describes. Those are only form names. Agency rules do not govern the DSCR loan, and the rent exhibit varies by program.
What the Network Allows on These Condos
On an investment property, select programs in the network finance non-warrantable condos to 75% and $1,500,000, subject to underwriting. Interest-only carries its own 75% ceiling, so the two limits line up. Warrantable condos use the broader leverage ladder, which runs higher at lower balances.
Condotels sit in a separate lane. Select programs allow them to 75% on a purchase and 65% on a refinance, up to $1,500,000, with $250,000 cash in hand required. That is a different property class, and the rent basis changes with it.
Entity vesting is welcome on these files, subject to program terms, though layered entities are not. An investor can hold the condo in a single LLC and qualify on the property’s rental income covering the payment, subject to lender guidelines. The entity documents still have to be clean, and the project review runs on the building regardless of who holds title.
Lendmire arranges these loans as a broker, with business-purpose financing in 41 markets, including Washington, D.C. Programs change, and every file is underwritten individually.
Tradeoffs: What Interest-Only Costs You
Interest-only means no principal paydown during the window. Equity grows only if the property appreciates. The payment also rises when the window ends and the loan recasts to full principal and interest over the remaining term. A ten-year interest-only window on a 30-year note amortizes over the final twenty years, so the payment steps up on a shorter schedule.
A forty-year term does not mean forty years of interest-only. On most programs it means a ten-year interest-only window on top of the amortizing period.
The exit is the part investors skip. A non-warrantable condo has a narrower buyer and lender pool than a warrantable one. When the window ends, you may need to refinance into a market where fewer lenders will touch the project. Plan the hold period and the refinance path before you choose interest-only. Tax treatment varies; consult a qualified professional.
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.
When Interest-Only Is the Wrong Choice
Skip interest-only when the file only works on the interest-only payment and the dues are already stretched. If a small assessment would push the ratio under the line, you do not have a cushion. The same goes for a short hold on a thin-margin condo with a weak refinance path.
It also fits poorly when the project is unstable. A building with pending litigation or deferred repairs can see dues jump. A payment that clears only barely on the interest-only test can slip below it after one special assessment.
On the other side, interest-only fits an investor who holds long, buys with real equity in the unit, and wants cash flow while the rent grows into the eventual payment. In that case the structure can make sense even at a modest ratio.
Where the General Rule Breaks
Condotels and short-term rental use. Fannie Mae’s Condo Status Finder FAQ lists hotel operations and managed short-term rentals as reasons a project cannot be financed through the agencies. Select DSCR programs may allow them, but usually with a different rent basis and tighter leverage. Short-term rental rules vary by city, county, HOA and property type, so investors should confirm local rules before relying on projected rental income. Lendmire’s piece Does a DSCR Lender Verify STR Permits on a Non-Warrantable Condo? covers the documentation side.
Small projects and detached units. Agency rules often waive full project review for detached units and very small projects, as KSN Law’s summary of Fannie Mae’s condo guidance explains. Do not assume the waiver carries over. DSCR programs set their own review.
Status changes during the contract. New litigation, a special assessment or a critical repair can flip a project to non-warrantable between contract and closing. A file that cleared as warrantable can change programs mid-stream. Pull fresh project documents before the file goes in.
Blanket loans. If several condos sit under one loan, interest-only windows convert to amortization on the same date.
Key Terms Defined
ITIA: The monthly payment of interest, taxes, insurance and association dues, with principal left out.
PITIA: The monthly payment of principal, interest, taxes, insurance and association dues.
Non-warrantable condo: A condo project that fails the agency standards for purchase and securitization.
Condotel: A condo project run partly like a hotel, usually with managed short-term rental use.
Interest-only window: The period when the borrower pays interest and no principal, which is 120 months on select programs.
Recast: The reset to full principal and interest payments when the window ends.
Frequently Asked Questions
Does interest-only always make a non-warrantable condo easier to qualify?
No. It helps only when the program tests the interest-only payment. If the program qualifies the file on the fully amortizing payment, interest-only improves cash flow after closing and leaves the ratio unchanged.
Do HOA dues count in the coverage calculation?
Yes. Dues sit in the payment on both the interest-only and amortizing tests. Heavy dues shrink the benefit of removing principal, and a special assessment can erase it. Get the dues figure early.
Are condotels treated the same as other non-warrantable condos?
No. Select programs allow condotels at lower leverage, 75% on a purchase and 65% on a refinance, with a $1,500,000 ceiling and $250,000 cash in hand, subject to underwriting. The rent basis is often different too, since managed short-term use is common.
What happens when the interest-only period ends?
The loan recasts to full principal and interest over the remaining term. On a ten-year window with a 30-year note, that means a twenty-year amortization, so the payment rises. Plan the refinance or sale before the window closes.
Can a sub-1.00 file still work on one of these condos?
Select lenders in the network review coverage below 1.00, but LTV and terms adjust, and the condo’s project review still applies. It is a structure a lender would review, not a promise of approval.
