If you’ve been brokering business sales for any length of time, you know that clean deals, where the buyer has everything they need, the valuation is uncontested, and the bank says yes on the first call, are the exception, not the rule.

Most deals have a gap somewhere. Maybe the seller’s asking price is higher than the bank’s appraised value. Maybe the buyer is short on equity. Maybe cash flow looks strong on paper but the tax returns tell a different story. These are the moments where a broker’s real value shows up—and where knowing how to structure a seller note can be the difference between a deal that closes and one that dies on the vine.

At Always.bank, we work closely with brokers on complex acquisition financing every day. Here’s a practical breakdown of what seller notes are, when they make sense, and how to structure them in a way that works for everyone at the table.

What Is a Seller Note, Exactly?

A seller note, sometimes called seller financing or a seller carry, is when the seller of a business agrees to accept a portion of the purchase price as a promissory note rather than cash at closing. Instead of getting paid in full on day one, the seller becomes a creditor: the buyer repays them over time, with interest, according to agreed-upon terms.

Think of it as the seller lending part of the purchase price to the buyer. It’s a real financial instrument, with a principal balance, an interest rate, a maturity date, and typically a subordination agreement that places it behind the primary lender.

“A seller note isn’t a workaround or a sign of a weak deal. It’s a legitimate financing tool that sophisticated buyers, sellers, and lenders use every day to get well-structured acquisitions across the finish line.”

In the SBA lending world, seller notes are well-established. The SBA 7(a) program explicitly recognizes seller financing as an eligible source of equity injection, which means structuring one correctly can open doors that would otherwise stay closed.

When Does a Seller Note Make Sense?

Not every deal needs one. But there are a handful of situations where a seller note isn’t just helpful, it’s often essential.

1. The Valuation Gap
   The seller’s asking price is higher than what the bank will lend against. A lender will typically finance up to a certain multiple of EBITDA or appraised value. If the seller wants more, a note bridges that difference without forcing a renegotiation that kills the deal.
2. Equity Injection Shortfall
   SBA 7(a) loans typically require 10% equity injection from the buyer. If the buyer’s cash is tight, a seller note structured on standby can count toward that requirement, giving buyers a path to ownership they couldn’t otherwise access.
3. The Seller Wants More Upside
   Sellers who believe strongly in the business they built may prefer to stay financially involved for a few years. A seller note lets them earn interest income on the carry while giving the buyer time to grow into the purchase price.
4. Tax Efficiency for the Seller
   Spreading proceeds over time via an installment sale can provide meaningful tax advantages for sellers. It’s worth encouraging your sellers to talk with their CPA early, sometimes the note structure is more attractive to them than a full cash payout.
5. The Transition Period
   When a business’s value depends heavily on the seller’s relationships or institutional knowledge, a seller note can serve as a built-in performance incentive. The seller stays motivated to support a smooth transition because their repayment depends on the buyer’s success.

The SBA Rules: What Brokers Need to Know

If you’re structuring an SBA-financed acquisition, the seller note has to fit within SBA guidelines. Getting this wrong can delay or derail approval. Here’s what matters most:

Standby vs. Full Standby
The SBA distinguishes between two types of seller note arrangements:

Full Standby means the seller agrees to receive no principal or interest payments during the term of the SBA loan. This is the cleanest structure from the lender’s perspective, and the SBA will allow it to count toward the buyer’s equity injection.

Partial Standby means interest-only payments are allowed during the SBA loan term, with principal deferred. This is sometimes acceptable, but lenders will want to confirm the cash flow can support the combined debt service.

Key Rule to Remember

Under current SBA guidelines, a seller note on full standby for the life of the SBA loan can count as equity injection—meaning the buyer may not need to bring as much cash to the table. This is one of the most powerful tools in acquisition financing, and many buyers (and some brokers) don’t know it exists.

Subordination Requirements

Seller notes in SBA transactions must be subordinated to the SBA lender. This means the primary lender gets paid first in the event of default. Most sellers understand this as a condition of the deal, it’s standard practice, but it needs to be clearly documented and agreed upon before the deal gets to underwriting.

Seller Note Size Limits

The SBA doesn’t cap how large a seller note can be in absolute terms, but it does look at the overall debt structure to confirm the business can service total debt. If the combined monthly payments on the SBA loan and the seller note are too high relative to cash flow, the deal won’t pencil. The size of the note needs to reflect realistic repayment capacity.

How to Structure a Seller Note That Gets Approved

The mechanics matter. A poorly structured seller note can confuse underwriters, stall the deal, or cause a last-minute decline. Here’s what a well-structured note looks like in practice:

• Interest Rate: Typically between 6% and 10%, depending on the deal. Rates should reflect market conditions and be clearly stated in the note document.
• Term: Often 3 to 7 years. Shorter terms can put pressure on cash flow; longer terms are generally preferred by buyers and lenders alike.
• Repayment Structure: Full standby (SBA preferred) or interest-only with deferred principal. Monthly amortizing payments are possible but require a strong cash flow analysis.
• Subordination Agreement: Required by the primary lender. This must be signed before closing and clearly subordinates the seller note to all obligations owed to the bank.
• Security: The seller note may or may not be secured. If it is, any collateral position must be subordinated to the primary lender’s lien.
• Documentation: A promissory note, subordination agreement, and any intercreditor arrangements should be drafted by legal counsel and reviewed by all parties before underwriting.

Broker Tip

Don’t wait until underwriting to disclose the seller note. Present the full deal structure, including the note amount, rate, term, and standby status upfront. Surprises in underwriting cost time and deals. Lenders like Always.bank appreciate brokers who bring a complete picture from day one.

Common Mistakes Brokers Make With Seller Notes

We’ve seen a lot of deals structured well and a few structured poorly. Here are the patterns that show up most often when things go sideways:

Misrepresenting standby status. Claiming a note is on full standby when there’s actually a side agreement for payments is a serious problem. Lenders verify. Don’t put your deal or your credibility at risk.

Not stress-testing the debt service. A seller note is additional debt. Before bringing a deal to a lender, run the numbers on total debt service coverage. If it doesn’t work at 1.25x DSCR or better, the lender’s answer is going to be no and you’ll have lost time getting there.

Failing to get seller buy-in early. Some sellers balk at a note because they don’t understand it or feel like it signals buyer weakness. Educate your sellers early. Frame it as a tool that gets them to their number, often a higher one, rather than a compromise.

Skipping legal review. A handshake agreement or a template from the internet isn’t a properly structured seller note. Real documentation protects everyone and gives the lender something they can work with.

How Always.bank Works With Brokers on Complex Deals

We built Always.bank to be the kind of lender that brokers actually want to call, not just for the easy deals, but for the complicated ones. We’re an online lender with deep SBA experience, and we know how to move quickly and communicate clearly when a deal has layers to it.

When you bring us an acquisition with a seller note, here’s what you can expect:

A real conversation, not a form. We’ll walk through the deal structure with you before you bring in the borrower. If something doesn’t work, we’ll tell you why and help you think through alternatives.

Clarity on structure early. We’ll let you know upfront whether the seller note qualifies as equity injection, what documentation we need, and what the likely timeline looks like—so there are no surprises down the road.

Speed that respects your client’s timeline. We typically close SBA loans in 45 to 60 days when borrowers are prepared. Complex structures don’t have to mean slow timelines if everyone comes to the table organized.

Partnership, not gatekeeping. Our job isn’t to say no. It’s to find a path to yes when the deal makes sense and to tell you honestly when it doesn’t so you can spend your energy on the right opportunities.

The deals that come with seller notes are often the most interesting ones, the businesses with real value, sellers who care about what happens next, and buyers with genuine skin in the game. Those are exactly the kinds of deals we want to be part of.
