The Quick Read: A seller note behind a DSCR first mortgage on a duplex, triplex or fourplex is tested twice: once for combined leverage, meaning all liens against value, and once for coverage, meaning whether the rent still covers the payments, and many programs do not allow a seller note in the structure at all. Where a select lender in the wholesale network permits one, the combined figure is held to that program’s leverage tier. The seller note also cannot stand in for your own cash down. Each lender sets its own rules, so get them in writing before you sign a contract that includes a seller carry.
- Combined LTV (CLTV) adds every lien together and divides by value. A seller second counts.
- Many programs do not allow subordinate financing. Those that do require full disclosure.
- On an investment-property purchase, most first liens land at 75%–80% LTV. Select high-leverage programs reach 85% with roughly a 700+ score.
- Rent is tested against the first payment and, in some programs, the seller note’s payment too.
- Clearing both tests matters. Equity alone does not rescue thin rent, and strong rent does not lift a leverage cap. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Key Terms Defined
DSCR (debt service coverage ratio): Monthly rent divided by the monthly housing obligation. A result of 1.00 means rent equals the payment.
PITIA: Principal, interest, taxes, insurance and any association dues. It is the payment figure DSCR measures rent against.
LTV and CLTV: LTV is the first mortgage divided by the property’s value. CLTV adds every other lien to the top of that fraction.
Seller carry-back (seller note): A loan the seller makes to you for part of the price. It is a promissory note secured by a recorded mortgage or deed of trust, per a market source’s explainer on seller financing.
Junior lien: A loan that ranks behind the first mortgage. If the property is sold or foreclosed, the first lien gets paid first.
Subordination agreement: A signed document in which a lien holder agrees to rank behind another loan.

What Are the DSCR Combined Leverage Requirements on a 2-4 Unit?
There is no single industry-wide number. A DSCR loan is a non-QM investor product, so each lender in the network writes its own leverage grid. What stays constant is the logic: the lender looks at all debt secured by the building, not just its own loan.
On a plain purchase with no second lien, LTV and CLTV are the same number. The seller note is what pulls them apart. Say you buy a fourplex with a first mortgage at 70% of value and the seller carries 10%. Your LTV is 70%. Your CLTV on that investment-property purchase is 80%.
Which number a lender holds to its grid depends on the program. Many programs do not allow a second lien at all. Others allow a disclosed, subordinate seller note and test the combined figure against the same tier as everything else. A few cap the seller note separately. So the first question is never “how much can the seller carry?” It is “does this program allow a seller note, and against which number is it measured?”
For the big picture on how these loans work, see Lendmire’s complete DSCR loans guide.
Can a DSCR Lender Even Accept a Seller Second?
Sometimes, and the answer is program by program. Most programs prefer a clean file: your cash in, one lien on title. A seller second changes that, so a lender that permits it will want every detail on paper.
Here is what lenders in the network typically look for:
- Your own cash in the deal. A seller note generally cannot replace your down payment. The seller carrying part of the price is one thing. The seller funding your equity is another, and most programs treat it as a no.
- First position. The DSCR loan is recorded first. The seller’s note sits behind it by design.
- Full disclosure. Every lien goes on the application. Hiding a seller second from the lender is misrepresentation, and it surfaces at title anyway.
- Arm’s-length terms. A sale between relatives, or one with a tenant or leaseback seller, is often disqualified no matter how the liens are arranged.
DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage.
How Does Underwriting Treat the Deal, Step by Step?
Underwriting runs in a fixed order, and the seller note touches most of the steps.
1. Appraisal sets value and rent. For two to four units, the appraisal form is Form 1025, the small residential income property report, as the Fannie Mae Selling Guide names it. DSCR is not an agency product. The form just shows where per-unit market rents come from and how they roll up to the building’s rent.
2. Value is chosen. Leverage is generally measured against the lower of the contract price or the appraised value, as the program allows. If you overpay on paper, the gap comes out of your pocket.
3. Liens are added. First loan plus seller note, divided by value, gives CLTV.
4. Leverage is checked. The result is compared with the program’s tier for your credit score, loan size and transaction type.
5. Coverage is run. Rent is divided by the first loan’s PITIA. Some programs then test rent against the first payment plus the seller note’s payment.
6. Reserves and documents are verified. The lender asks for the seller note, the purchase contract, the settlement statement and title work showing its loan in first position.
Reserves vary by lender, leverage, loan size and transaction type. Commonly they run about 6 months of PITIA, and loans above $1,500,000 typically step up to about 9 months. Lendmire’s piece How Jumbo Loan Leverage and Reserves Work for a 2-4 Unit Rental covers that side in more detail.
The Two Gates
Think of the file as passing through two gates. A deal needs both.
| Gate | What it measures | What fails it | Typical fix |
|---|---|---|---|
| Permission | Is a seller second allowed? | Program bars subordinate debt | Pick a different program |
| Combined leverage | All liens ÷ value | Note pushes CLTV over the tier | Smaller note or more cash |
| Combined coverage | Rent ÷ stacked payments | Thin rent after the note’s payment | Lower note payment |
| Down payment source | Whose cash is in | Seller funds your equity | Use your own cash |
| Reserves | Liquid cash after closing | Cash drained at closing | Smaller note or more savings |
| Title | Lien order on record | Another lien ahead of the DSCR loan | Clear or subordinate it |
Most failed files break the combined leverage or combined coverage gate rather than permission. The fixes differ, which is why you need to know which one binds.
How Do You Work Out Combined Leverage Room?
Use one formula: room = value × combined ceiling − first lien. In percentage terms, ceiling minus first-lien LTV gives the room for a seller note, as a share of value.
Run it on a modeled example. These inputs are assumptions for illustration, not market data.
- Assume a program that holds the combined figure to 80% on an investment-property purchase.
- Assume your first lien is 70% of value.
- Room for a seller note is 10% of value. Your own cash covers the rest, which is the remaining 20% of value before closing costs.
Now flip it. Assume the first lien is 75% and the seller wants to carry 10%. Combined leverage is 85%. On a program capped at 80% on that purchase, the file fails the leverage gate. A select high-leverage program at 85% with roughly a 700+ score might accommodate it, but only if it allows a seller second and counts it at face value.
Notice what the formula leaves out. A bigger seller note does not mean less cash from you overall. It means a thinner equity cushion and an extra payment. Lenders see that as more risk, not less.
How Does the Seller Note Affect Rent Coverage?
A seller note can drag coverage below the line even when leverage passes. On a 2-4 unit, the coverage test pools the rent from every unit, then divides by the payment obligation the program counts.
Run two modeled scenarios. The ratios are illustrative assumptions.
| Scenario | First lien alone | With seller note | Leverage gate | Coverage gate |
|---|---|---|---|---|
| A: Pass | About 1.30x | About 1.08x | Within tier | Clears 1.00 |
| B: Fail | About 1.15x | About 0.92x | Within tier | Below 1.00 |
In scenario A, the seller note’s payment is about a fifth the size of the first payment. Stacked, rent still clears 1.00. In scenario B, the note’s payment is about a quarter of the first payment. Leverage is fine, but coverage slips under 1.00.
Where does that leave scenario B? A DSCR of 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. So scenario B is not automatically dead. It likely means lower leverage, a different structure or a stronger credit profile. Whether it works depends on lender guidelines, credit approval and property review.
Not every program stacks the payments. Some test rent against the first payment only. Ask which method the lender uses before you negotiate the note’s size.
A caution on what the ratio means. DSCR compares rent to PITIA only. Clearing 1.00 is not the same as positive cash flow, because repairs, vacancy, management, utilities and capital expenses sit outside the calculation. A seller note adds a payment those costs must also be paid from.
How Do Seller Note Terms Change the Test?
The note’s own terms feed the underwriting. Two notes for the same amount can land very differently.
| Note type | What it is | Underwriting question |
|---|---|---|
| Amortizing | Principal and interest each month | Is the payment stacked on coverage? |
| Interest-only | Interest paid, principal due later | Does the lender count the payment or the full term? |
| Balloon | Short term, large payoff at end | How will it be paid off or refinanced? |
| Deferred | No payments for a stretch | Does the lender still count it? |
Treatment is program-specific. A balloon note creates a refinance event later. A deferred note may look free on day one and still draw questions from underwriting. Longer terms and lower payments make stacked coverage easier. Short balloons make it harder, because the payoff comes due while you are still stabilizing the building.
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.
Edge Cases Where the General Rule Breaks
A note for part of the price versus a note for the down payment. These are not the same thing. A seller carrying part of the price behind a disclosed first lien is a structure some programs accept. A seller note that funds your down payment is a different structure and a harder sell.
An existing loan on the seller’s side. If the seller still owes a mortgage on the property, lenders get cautious. Your DSCR loan needs first position, so the old loan must be paid off at closing.
Wrap-around notes. The seller’s old mortgage stays in place and your new note wraps around it. The wrap becomes a junior lien, as Lone Star Land Law’s seller-finance overview describes it. A DSCR lender that needs first position generally cannot use it.
Contract for deed. The seller keeps legal title until you pay in full. That is not a recorded seller note where you hold title, and it does not fit a standard DSCR first-lien structure.
Due-on-sale and the 1-4 unit line. A federal statute, 12 U.S.C. §1701j-3, limits when a lender can call a loan due on transfer. Its exceptions apply only to residential property with fewer than five dwelling units, as Foust & Foust explain. A 2-4 unit sits inside that line, and a subordinate lien that does not transfer occupancy rights typically does not trigger the clause. That governs an existing first lender calling a loan. It does not oblige any DSCR lender to approve a seller second.
Property type. Manufactured homes, log homes and barndominiums are not offered in these DSCR programs, with or without seller financing.
What Happens When You Refinance Later?
A seller note does not stay second forever. When you refinance, the new first lien needs first position. The seller must either be paid off or sign a subordination agreement. Nolo explains that refinancing with multiple mortgages only works when the junior holders agree to change their positions.
Sellers often decline. That leaves payoff as the cleaner route. On a cash-out refinance of an investment property, leverage tops out around 75% LTV across most of the network, and about 6 months of seasoning is the common expectation. The proceeds and the new first lien must be enough to retire the seller note, so size the original note with that exit in mind.
If the seller is a friendly party, ask for a clause in the note that allows prepayment without penalty and commits them to subordinate on request. Put it in writing at the start.
Which Gate Is Binding?
Work backward from the failure.
- Leverage binds, coverage is fine. Shrink the seller note, add your own cash or negotiate the price down.
- Coverage binds, leverage is fine. Lower the seller note’s payment with a longer term, or reduce the note. A larger down payment lowers the first payment too, which can lift the ratio.
- Both bind. The deal is probably priced too high for the rents. Renegotiate or walk.
- Permission binds. The program will not take a seller second. No amount of equity changes that. Move to a different program or drop the carry.
A larger down payment never erases leverage caps, credit floors, reserve rules or property eligibility. On credit, a 620 floor exists in parts of the network, most programs want around 660, and 700+ unlocks the strongest leverage tiers.
Mistakes That Sink These Files
- Signing the contract before checking permission. The seller is told yes, then the lender says no.
- Sizing the note without running coverage. A note that looks small can still push the ratio under the line.
- Counting on the appraisal. A thin appraised rent limits the first loan even if combined leverage has room.
- Hiding a lien. Undisclosed debt is misrepresentation, and title work finds it.
- Draining reserves for the down payment. Cash left after closing matters to the lender and to you.
- Ignoring the exit. A balloon with no refinance plan is a deadline, not a structure.
Tax treatment varies; consult a qualified professional before relying on any deduction tied to seller interest.
What to Ask Your Lender Before You Write the Offer
1. Does this program allow a subordinate seller note on a 2-4 unit purchase?
2. Is the combined figure tested against my leverage tier, and which number do you use for value?
3. Is the seller note’s payment included in the coverage test?
4. Can the note cover any part of the down payment? (Expect no.)
5. What documents does the seller note require, and who must sign?
6. What reserves apply at my loan size and leverage?
7. What happens to the note on a later refinance?
Frequently Asked Questions
Can I use seller financing as my down payment on a DSCR loan?
Usually not. Most programs want your own cash in the deal, unencumbered. A seller note that covers part of the price behind a disclosed first lien is a different structure, and only some select lenders in the network accept it. Ask before you write the offer.
Does the seller note count in the DSCR calculation?
It depends on the program. Standard coverage is rent divided by the first loan’s PITIA. Some programs also add the seller note’s payment to the test. Interest-only, balloon and deferred notes can be treated differently, so ask how the lender counts yours.
Do I have to tell the lender about a seller second?
Yes. Every lien must be disclosed. Lenders see liens at title anyway, and hiding one is misrepresentation. Disclosure lets the lender decide whether to proceed and how to size the first loan.
Does the seller have to subordinate to the DSCR loan?
On a purchase, the structure usually places the DSCR loan first and the seller note second at recording, so no subordination is needed. On a later refinance, a junior holder does not automatically stay behind the new loan. The seller either signs a subordination agreement or gets paid off.
Is there one combined-leverage cap that every DSCR lender uses?
No. Purchase first liens most often land at 75%–80% LTV on investment property, with select high-leverage programs reaching 85% at roughly a 700+ score. Whether a seller note counts toward those figures is lender-specific. Subject to lender guidelines, credit approval and property review.
Where This Leaves You
A seller note can reduce the cash you bring to closing, but it adds a second payment, a second lien and a later refinance problem. The strongest files clear both tests: enough equity and enough rental coverage.
