The Quick Read: You buy the property with a DSCR first mortgage from a lender and a smaller note the seller carries behind it, which can cut the cash you bring to closing. It works only if the first lender allows a junior lien, the rent still covers the payments once both are counted, and total leverage stays inside program limits.
- The first lender decides whether a seller second is allowed. Nothing gives a rental buyer a right to one.
- Most programs in the network treat the second’s payment as part of the monthly obligation, so it lowers coverage.
- On a purchase, most files land at 75%-80% LTV on the first loan, with select high-leverage programs reaching 85% LTV at roughly a 700+ score.
- The seller note must be disclosed to the first lender. A hidden second is a red flag.
- Plan the exit. The note usually has to be paid off or subordinated when you refinance.
A first-time landlord usually runs into the same wall: the down payment. A seller second is one of the few creative tools that can move that wall without breaking the loan. It is also easy to get wrong. This guide walks through the mechanics in order, then shows where the structure breaks.

What Is a DSCR First Loan Plus a Seller Second?
The stack has two loans on one property. The DSCR lender funds the senior loan and sits in first lien position. The seller accepts less cash at closing and carries the difference as a note, secured by a mortgage or deed of trust recorded behind the first.
DSCR means debt service coverage ratio. It compares the property’s rent to its monthly housing obligation: principal, interest, taxes, insurance, and any HOA dues (together, PITIA). The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. It is designed for non-owner-occupied investment properties, and because it is a business-purpose investor loan, it is reviewed differently from a standard owner-occupied mortgage.
Picture a purchase split three ways: a first loan from the lender, a seller note, and your own cash. The seller note stands in for part of the down payment. That is the whole appeal.
The seller is always in second position in this structure. This is not the same as a “subject-to” deal, where the seller’s old loan stays in place. A seller second is a new junior debt behind a new first. The seller generally needs to be paid off at closing by the first loan, which usually means the seller owns the property free and clear or close to it.
Key Terms Defined
First lien: the senior mortgage. It gets paid first if the property is sold or foreclosed.
Seller second (seller carryback): a note and mortgage in which the seller finances part of the price, junior to the first.
Combined LTV (CLTV): all liens added together, divided by the appraised value.
Subordination agreement: a signed document in which a lienholder agrees to stay behind another loan.
PITIA: principal, interest, taxes, insurance, and association dues. This is the payment the rent is measured against.
Balloon: a lump-sum payoff of the remaining note balance due on a set date.
Seasoning: the waiting period a lender wants between two events, such as buying and refinancing.
Will a DSCR Lender Allow a Seller Second?
Some will and many won’t, and that is the first thing to find out. Across the wholesale network, lenders differ on whether they permit subordinate financing at all, what combined leverage they accept, and whether you must put in a minimum amount of your own money. Nothing in federal law hands a rental buyer the right to add one.
Ask in this order, before you write an offer:
1. Does the program permit seller or other subordinate financing?
2. What is the maximum combined LTV?
3. Is a minimum borrower cash contribution required?
4. Does the seller-note payment count in the coverage calculation?
Get the answers in writing. A broker who sees many lenders’ guidelines can screen programs for you, because the answers vary by lender, leverage, and loan size. Non-QM programs, which fall outside standard agency lending rules, tend to be more flexible than banks here, though not universally.
What the Law Does and Doesn’t Protect
Investors sometimes hear that federal law lets them add a second lien freely. It doesn’t, for rentals. The due-on-sale limit on subordinate liens in 12 CFR 191.5 applies to a home occupied or to be occupied by the borrower, as the regulation text shows. Your first lender’s own note and guidelines govern. Treat permission as a contract question, not a legal entitlement.
How Does Underwriting Treat the Second Payment?
Assume it counts. The second’s payment is a debt on the property, so a lender will typically add it to the obligation before dividing rent by it. Whether a deferred, interest-only, or balloon note is treated differently is lender-specific, so confirm it per program.
Here is why that matters. Say a property clears the first loan at about 1.25x on its own. Add a seller note with a regular payment and coverage might slide toward 1.00x or below. A modest second can push a property under the program floor. The first loan can pass alone and fail combined.
Coverage rules to keep straight:
- 1.00 is where select programs start. It is a floor for specific programs, not the standard.
- Stronger ratios open better pricing and leverage.
- A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.
- Clearing 1.00 is not positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capex sit outside it.
Lenders also test combined leverage. Take the first loan plus the seller note and divide by the appraised value. A first loan at 75% LTV on a purchase leaves only a thin slice for a second. Because most files land at 75%-80% LTV on a purchase, the seller note often fits inside what the lender would let you borrow anyway, which is where a program that permits it can help. Select high-leverage programs reach 85% LTV at roughly a 700+ score, but anything above those caps is off the table however creative the note.
A bigger down payment lowers the payment and can lift coverage, but it never erases leverage caps, credit floors, reserve rules, or property eligibility. Strong files clear both tests: enough equity and enough rental coverage.
Step by Step: From Offer to Closing
1. Screen the program. Confirm the first lender permits a second and what combined LTV it accepts.
2. Run coverage both ways. Test the property with the first loan alone, then with the seller note’s payment included. If it fails combined, resize the note.
3. Write the offer with the structure in it. Name the seller note, its size, term, payment type, and any balloon. Disclose it to the first lender at this stage, not later.
4. Negotiate the note. Size, term, interest-only versus amortizing, and the balloon date are all negotiable. Asking the seller to carry a second and cut the price at once weakens your position, so choose which lever you want.
5. Order the appraisal and rent schedule. The appraised value drives combined leverage. A low appraisal squeezes the whole stack.
6. Draft the documents. Expect a seller promissory note, a mortgage or deed of trust recorded in second position, a lien-position acknowledgment, and disclosure of the second on the settlement statement. A title company or real estate attorney should draft it.
7. Close and record in order. The first lender’s mortgage records first. The closing agent controls recording order and funds flow. The seller’s carried equity shows as a non-cash credit.
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 Design a Seller Note a Lender Will Accept?
Design it around the coverage ratio, not around what the seller wishes. Four levers matter.
Size. A smaller second protects coverage and combined leverage. A large one risks both.
Payment type. Interest-only or longer amortization lowers the monthly payment but may be treated differently from lender to lender. Confirm before you offer it.
Term and balloon. A short balloon date forces a payoff or refinance soon. That can be fine if you plan an exit, risky if you don’t.
Prepayment terms. You want the right to pay it off early without a penalty, since you will probably refinance.
How Do You Pitch It to the Seller?
Seller carry works best when the seller owns the property outright and values steady income over a lump sum. The seller earns interest, as a bank would, and may be able to command a firmer price in exchange for flexible terms. Be honest about the seller’s risk, because they will be thinking about it.
A second-lien holder has thin protection when equity behind them is small. If the first loan defaults, the seller may need to buy out the first lender to protect the second. Don’t oversell. Offer a reasonable interest term, a real down payment from you, and a sensible balloon date. Keep the seller’s own attorney in the loop and recommend they get independent advice.
On the legal side, seller-financing limits under the Dodd-Frank rules mostly target consumer loans on owner-occupied one- to four-unit homes. A law-firm summary says the exemptions apply to owner-occupant sales and do not cover a buyer who won’t live there. That is general information, not legal advice, so the seller should check with counsel.
What If the Second Breaks the Math? Alternatives
Not every deal can carry a second. When coverage or leverage fails, you have other levers.
| Option | Effect on loan | Effect on coverage | Cash at closing |
|---|---|---|---|
| Seller second | Adds a junior lien | Lowers it | Reduces it |
| Seller credit | No new lien | No change | Lowers cash to close |
| Price reduction | Smaller first loan | Often improves it | Lowers the price |
| More cash down | Smaller first loan | Improves it | Raises cash needed |
If a lender refuses the second, the usual fallback is converting it into a seller credit or a price reduction. If the appraisal comes in low, the combined leverage may fail even when the first loan alone would pass. Resize before you waive contingencies. If the seller backs out, you are back to a standard purchase at 75%-80% LTV on the first loan. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Exit: What Happens When You Refinance?
Plan this on day one. A new first lender wants first position. If the old first is paid off, a recorded second moves up unless its holder signs a subordination agreement. Holders don’t always agree. A legal-education explainer notes that second-lien holders may refuse to subordinate.
The practical consequence is that the seller second may have to be paid off at the refinance. That’s why balloon dates and prepayment rights matter. On a cash-out refinance, the network generally tops out near 75% LTV on standard rentals, with about 6 months of seasoning as the common expectation. Your exit math has to cover the seller note’s payoff within that ceiling.
Where the General Rule Breaks
- Owner-occupied protections don’t carry over. Don’t assume a rule written for homes you live in shields your rental.
- Seller with an existing mortgage. Owner carry is a hard sell if the seller isn’t free and clear. It then turns into a wrap or subject-to deal, which is a different structure.
- Secret seconds. An undisclosed second is a red flag. The first lender should know about the second, and the settlement agent should record both in the right order.
- Ineligible property types. Manufactured homes (single- and double-wide), log homes, and barndominiums are not offered through the network’s DSCR programs, so no seller note rescues them.
- Short-term rentals. Purchase leverage tops out at 75% LTV, with a 640+ score and about 12 months of hosting history expected. 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.

Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
What Does a First-Timer Need Besides the Structure?
A seller second doesn’t replace the basics. Credit tiers start at a 620 floor in parts of the network, most programs want around 660, and 700+ unlocks the strongest leverage. Reserves vary by lender, leverage, and loan size, commonly around 6 months of PITIA, stepping up to about 9 months on loans above $1,500,000. Standard programs run up to $3,000,000, and above $2,500,000 the network generally holds to 30-year fixed structures. Everything is subject to lender guidelines and individual underwriting.
Add the practical items: a property manager or a plan for one, an entity if you want one (subject to lender program eligibility), and insurance quotes in hand before you commit. For a general walkthrough of the loan itself, see the complete DSCR loans guide. For the broader first-purchase playbook, Lendmire’s article How to Buy a First Rental With a DSCR Loan and Seller Carry covers the companion scenario.
Honestly, the real question here is whether the property can carry two payments. If it needs the second to make the numbers work, the numbers are probably too thin. That’s a judgment call a broker can pressure-test before you’ve spent money on an appraisal.
Tax treatment varies; consult a qualified professional.
Frequently Asked Questions
Can a first-time investor really do this?
Yes, if the program allows it and the file clears coverage with both payments counted. First-timers should expect to show credit, reserves, and a property that meets eligibility rules. Having no landlord history doesn’t rule out a DSCR purchase, but it does make clean documentation and conservative leverage more important.
Does the first lender have to approve the second?
Yes. The first lender’s guidelines and note terms control. Disclose the seller note before the contract is final and get the lender’s position in writing. Hiding it from the lender is a serious mistake and can jeopardize the loan.
Does the seller second count against my coverage ratio?
Assume it does. Most underwriting adds subordinate debt payments to the monthly obligation, which lowers the ratio.
Can the seller second serve as my down payment?
Sometimes, depending on the program. Some lenders want a minimum amount of your own funds regardless of the second. A second can replace part of the cash needed only if the first lender permits it and any minimum contribution is met.
What if I refinance later?
The seller second typically has to be paid off or subordinated. A new first lender wants first position, and the seller isn’t obligated to subordinate. Build a balloon date and prepayment right into the note so your exit works.
