These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
The Quick Read: The choice is between funding the full equity yourself on a DSCR first lien and asking the seller to carry part of that equity as a second note behind the lender. The first path is cleaner and fits buyers who have the cash. The second only works if the first-lien program allows a junior lien and the rent still covers both payments. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
- A DSCR first lien qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
- Purchase leverage on most investment-property files is 75%-80% LTV. Select high-leverage programs reach 85% LTV on a purchase with roughly a 700+ score.
- Short-term-rental purchases top out at 75% LTV, with a 640+ score and about 12 months of hosting history expected.
- Many DSCR programs do not allow a seller second at purchase. Select lenders in the network may, with terms set by the program.
- A second note adds a payment, and rent has to carry both.

As of Oct 15, 2026 · General Freddie Mac market benchmark, not a Lendmire loan offer. Nightly rate, occupancy, taxes, and insurance are editable estimates. 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.
Who Each Option Is Really For
The buyer with the cash is the fit for the first-lien-only path. The buyer who is short on cash and has a motivated seller is the fit for the seller second. That second buyer carries more risk. The structure also depends on a lender’s permission, not just the seller’s willingness.
A first Airbnb adds a wrinkle. A 15% down payment means 85% LTV. Across the wholesale network, that tier is a select high-leverage purchase program for standard rentals, and it generally wants a score near 700 or higher. Short-term-rental collateral is treated differently. Purchase leverage on STR files tops out at 75% LTV, so the buyer funds at least 25% in equity.
The two options therefore overlap less than the title suggests. If you want 15% down on a true STR file, you face a gap of roughly ten points of equity. A seller second is one way people try to fill that gap. Another is to underwrite the property as a long-term rental and skip the STR income. Each choice has trade-offs, covered below. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
Side-by-Side
The seller-second column shows published industry norms. Program rules differ, and Lendmire’s wholesale network places both structures depending on the lender.
| Factor | DSCR first lien, buyer funds equity | First lien plus seller second |
|---|---|---|
| Review basis | Property rent vs. PITIA | Rent vs. PITIA, second may count |
| Borrower documentation | Credit, funds, entity papers | Same, plus note and lien documents |
| Source of equity | Buyer’s own verified funds | Part buyer funds, part seller note |
| Lender permission | Standard for the program | Program-specific; often not allowed |
| Number of payments | One | Two |
| Entity vesting | LLC or personal, per program | Same, seller may want a guarantee |
| Reserves | Per program and leverage | Per program, plus second’s exposure |
| Timeline | Fewer parties to coordinate | More parties, more document review |
| What breaks first | Appraisal or coverage shortfall | Lender refuses the lien, or coverage fails |
How a DSCR First Lien Works on a First Airbnb
Coverage is the property’s rent used for lender review divided by the full monthly obligation: principal, interest, taxes, insurance, and any HOA dues. Many select programs start at 1.00 coverage, and stronger ratios open better leverage tiers. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.
For an STR purchase with no operating history, income is typically supported by an appraiser’s short-term-rental analysis. Some programs also accept a market projection. Others fall back on the appraiser’s long-term market rent, which usually produces a lower coverage figure. Programs differ, so ask which method applies before you pick a property.
Clearing 1.00 does not mean positive cash flow. The calculation sees rent and PITIA only. Repairs, vacancy, management, utilities, furnishing, and capex all sit outside it. A first Airbnb has no actual history, so that gap deserves a cushion.
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.
Credit and reserves apply under either option. A 620 floor exists in parts of the network, and most programs want about 660. STR files generally want 640 or better. Reserves run commonly around 6 months of PITIA, though they vary by lender, leverage, loan size, and transaction type.
How a Seller Second Changes the File
A seller second is a junior note secured behind the lender’s first lien. The seller agrees to carry part of the price and gets paid over time, often with a balloon. The seller funds no cash at the table. The note shows up as a credit on the settlement statement, and the first lender funds its share.
Here is the catch. Many DSCR programs do not allow another lien on the property being bought. Underwriting looks at the property and the borrower’s credit, and lenders want the buyer to have capital in the deal. A note from the seller is not the buyer’s own money. It is added leverage.
Some select lenders in the network do review subordinate financing. When they do, they typically set a combined LTV cap that counts both liens. They also decide whether the second’s payment goes into the coverage ratio. Both points are program-specific. Treat any answer from a seller, an agent, or an online post as unconfirmed until the lender confirms it in writing.
General seller-finance structure is covered in this seller financing overview. It is not DSCR program data, so use it for how seller notes work, not for what a lender will accept.
Disclosure is not optional. The first lender needs to know about the second. Hiding a subordinate note or restructuring it to look like something else misstates the source of funds. That is not a strategy.
A Modeled Example in Ratios
This is a hypothetical structure, not a quote. Assume a first Airbnb purchase where the buyer funds 15%, the seller carries 10%, and the first lien covers 75% of the price. Combined leverage is 85% of the price. The first lien sits at the STR purchase ceiling of 75% LTV. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Now assume the first lien alone produces coverage of about 1.25x. That clears a 1.00 floor with room to spare. Add the seller note as a second payment, and if the program counts it, coverage might drop to roughly 1.05x. That is still passing on paper. It leaves almost no margin if the projected STR income comes in light.
Run it the other way. Assume the first lien alone sits near 1.10x. Add a second payment and coverage falls below 1.00. The file now needs a smaller seller note, a bigger buyer down payment, or a different income method. A sub-1.00 path is available through select lenders in the network, with leverage and terms adjusted, but it is a separate path with its own conditions.
A deal can pass with the first lien alone and fail once the second is added. Test both numbers before the offer, not after.
When the 15% Down First Lien Is the Better Fit
Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Choose the first-lien-only path in these cases:
- You have the cash and the credit. A score near 700 or above matters for the highest-leverage tiers, and you can fund the equity, closing costs, and reserves from your own verified funds.
- The deal is thin on coverage. One payment is easier to cover than two, and a first Airbnb has no history to back up the projection.
- You want fewer parties. A deal with no seller note has no subordination terms, no seller consent at refinance, and no balloon date to manage.
- You plan to hold in an entity. An LLC can take title on a first-lien-only file, subject to lender program eligibility. A seller carrying a note to an LLC often asks for a personal guarantee, which adds friction.
- You may refinance later. Without a junior note, the first lien can be refinanced on its own terms.
One reality check. Before relying on the 85% LTV tier, confirm whether the property will be underwritten as a standard rental or as an STR. The tiers are not interchangeable. Ask which one your file falls under before you commit to a down payment number. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
When the Seller Second Is the Better Fit
Choose the seller second only when all of these line up:
- The first lender confirms in writing that a subordinate lien is permitted. Get the combined LTV cap and whether the second’s payment counts in coverage.
- Rent covers both payments with a cushion. Aim for margin beyond the minimum, since projected income is untested.
- The seller wants the structure. Sellers who want steady payments, or who have no mortgage balance of their own, are more likely to agree than sellers who need cash out.
- You have a plan for the balloon. A seller note often matures before the first lien does. The exit is usually a refinance, and the seller may need to consent to staying subordinate if the first lien is replaced.
- Your attorney or title company has reviewed the note. Seller financing to an investor involves rules that vary by state, so a qualified attorney should check them for both sides.
The federal due-on-sale statute often comes up here. Garn-St Germain limits a lender’s ability to call an existing loan due when a subordinate lien is created on residential property of fewer than five units. That protects an existing borrower from acceleration. It does not require a new DSCR lender to approve a seller second at purchase, so do not treat it as a green light.
What Breaks First on Each Path
First lien only:
- The appraisal comes in low, which reduces the loan amount and raises the cash you need.
- The STR income analysis is lower than the projection, so coverage falls short.
- Hosting history is thin for an STR program, so the file gets pushed toward long-term rent underwriting.
- Reserves are not documented clearly.
First lien plus seller second:
- The lender refuses the junior lien after the offer is accepted.
- Coverage fails once the second payment is counted.
- The seller backs out or asks for terms the lender will not accept.
- Title surfaces an issue with the note or its recording.
- The balloon arrives before refinancing is workable.
The second list is longer because the structure has more moving parts. That is a reason to confirm permission first, not a reason to avoid it.
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.
Key Terms Defined
DSCR: Debt service coverage ratio, the property’s rent used for lender review divided by its full monthly obligation.
PITIA: Principal, interest, taxes, insurance, and any association dues, the monthly obligation used in the ratio.
LTV: Loan-to-value, the first-lien balance as a share of price or appraised value.
CLTV: Combined loan-to-value, which adds every lien on the property together.
Seller carry: The seller agrees to be paid part of the price over time instead of in cash at settlement.
Subordination: An agreement that a junior lien stays behind the first lien in payment priority.
Common Mistakes
- Treating the seller note as the buyer’s own money. Lenders see it as a lien, not as cash from you.
- Writing the offer before asking the lender. A seller’s yes does not override the first-lien program’s rules.
- Counting only the first payment. If the second counts in coverage, the ratio is lower than you modeled.
- Assuming 15% down applies to STR collateral. STR purchases top out at 75% LTV.
- Equating a passing ratio with cash flow. The ratio ignores operating costs and setup cash.
- Hiding the second. Undisclosed subordinate debt misstates the file. Leverage and reserves vary by lender and program, and final terms follow the full file review.
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.
The Verdict
Pick the first-lien-only path if you can fund the equity. It has fewer failure points, one payment, and cleaner exits. Pick the seller second only after a lender has confirmed in writing that it permits a junior lien, you have run coverage with both payments, and you have a realistic refinance plan.
Either way, a larger down payment can lower the payment and lift coverage. It does not erase leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage. For the full picture of how these programs fit together, see the complete DSCR loans guide.

Frequently Asked Questions
Can a seller carry a second behind a DSCR loan?
Sometimes, but many programs do not allow it at purchase. Select lenders in the network may review it, with a combined LTV cap and their own view on whether the second’s payment counts. Get the program’s written position before negotiating with the seller.
Does a seller note count toward my cash to close?
Usually not as your own funds. Lenders look for verified borrower capital in the deal, and a seller note is another lien. The program decides how the note is treated in combined leverage and in the coverage ratio.
Does rent have to cover the second payment too?
That is program-specific. Where the second counts, the ratio is rent against both loans, so it is lower than the first-lien number. Model both versions before you make an offer.
Is a seller second better for a first-time Airbnb buyer?
Usually not, unless cash is the real constraint. A first-time buyer has no operating history, so the income is a projection, and layering a second payment on a projection raises the risk. If a lender allows it, keep the note small.
Can an LLC take title under either option?
Often yes, subject to lender program eligibility. Entity documents and any personal guarantee follow the program’s rules. A seller carrying a note to an LLC may ask for a guarantee on top of that.
