Seller financing is one of the most useful tools in a buyer's deal structure toolkit — but only if you know what normal looks like. Ask for terms that are too aggressive and you lose credibility with the seller. Accept terms that are too rich and you're carrying expensive debt that compresses your returns for years. Here's what typical seller notes actually look like, how to negotiate them, and how they interact with your DSCR.
How Much Seller Financing Is Normal?
In the $1M–$5M acquisition market, seller notes typically represent 10–20% of the purchase price. At the low end, the seller carries a small note to bridge the gap between SBA financing (up to 90%) and the buyer's equity. At the high end, a motivated seller might carry 20–30% — particularly in deals where the buyer has less cash to bring to closing, or where the deal structure includes an SBA loan that requires the seller note on standby as the equity injection.
Seller financing above 30% of the purchase price is less common in SBA-backed deals because lenders want to see a meaningful equity position and a clearly subordinated seller note. In all-cash or non-SBA deals, seller financing can go higher — sometimes to 50% or more of the price — but these structures require careful legal documentation and a clear payment priority in case of default.
The amount of seller financing a seller will accept depends heavily on their motivation. A seller retiring with adequate liquidity may prefer a clean close with minimal financing. A seller who needs the sale to close quickly — or who wants to stay financially engaged in the business's success — may prefer to carry a note. Understanding the seller's situation is the first step in knowing how much seller financing is on the table.
Rate & Term Benchmarks
Seller note interest rates typically run in the 5–8% range in the current market. Rates are negotiable — unlike SBA loans, which are tied to Prime — and the right rate depends on the size of the note, the term, and the standby period.
For notes under $200K, sellers often accept 5–6% because the absolute dollar amount of interest is modest and they're more focused on the overall deal structure than the financing rate. For larger notes — $300K–$500K — sellers may push for 7–8% to ensure the note delivers meaningful passive income during the repayment period. If the note is on standby (no payments during standby), sellers sometimes negotiate a higher rate to compensate for the deferred income.
Term length for seller notes most commonly runs 3–7 years. Shorter terms (3–4 years) mean higher annual payments but lower total interest cost — better for the seller in present value terms, potentially challenging for buyer cash flow in early years. Longer terms (6–7 years) reduce the annual payment, improve DSCR, and give the buyer more runway — at the cost of more total interest paid over the life of the note.
As a buyer, you generally want the longest term at the lowest rate that the seller will accept. As a seller, the reverse is true. Most deals land somewhere in the middle — a 5–6 year term at 6–7% is a common landing point in the $1M–$3M deal range.
- Typical seller note size: 10–20% of purchase price
- Interest rate range: 5–8%, negotiable (not Prime-tied)
- Term length: 3–7 years, most common in the 5–6 year range
- Standby period: 0–36 months depending on SBA lender requirements
Standby vs. Non-Standby Notes
The most important structural decision in a seller note isn't the rate or the term — it's whether the note is on standby or immediately active. These two structures have fundamentally different implications for DSCR, SBA approval, and the seller's cash flow during the repayment period.
A non-standby seller note begins amortizing immediately at close. Payments are made monthly to the seller starting in month one. Because the note is active, SBA underwriters count the annual note payment in the DSCR denominator from day one. This means a $150K note at 6% over 5 years adds roughly $35,000/year to your debt service — which directly reduces your DSCR calculation. If the deal is already tight on coverage, an active seller note can push DSCR below the 1.25x threshold and kill the SBA loan.
A standby seller note requires the seller to receive no payments — no principal, no interest, no fee of any kind — for the duration of the standby period, typically 24 months. In exchange, the lender treats the note as equity rather than debt for DSCR purposes during standby. This can allow the buyer to close with no personal cash down (the seller note counts as the equity injection) while improving year-one DSCR by eliminating the note from the coverage calculation.
After standby ends, the note activates and begins amortizing normally. Your DSCR will drop at that point — and you need to model the year-3 scenario before you agree to standby terms. A deal that clears 1.40x in year one with standby might drop to 1.18x in year three when the seller note activates. If the business hasn't grown, that creates real cash flow pressure.
Sellers generally prefer non-standby notes — they want to start receiving income as soon as possible after the sale. Buyers with SBA financing often need standby. Negotiating this point early prevents last-minute deal complications when the lender's requirements conflict with what the seller agreed to.
Combining With an SBA Loan
Most seller notes in the $1M–$5M deal market exist alongside SBA 7(a) financing. The SBA loan covers 80–90% of the deal; the seller note covers 10–20%. Understanding how these two debt instruments interact is critical before you propose a structure to either the seller or the lender.
The SBA requires that any seller note be fully subordinated to the SBA loan. This means in a default scenario, the SBA lender gets paid first — the seller note holder only receives proceeds if there's anything left after the SBA debt is satisfied. Sellers need to understand and accept this priority before they agree to carry a note. Most experienced sellers and their advisors are familiar with subordination; first-time sellers may need it explained.
From a DSCR perspective, the combined debt service of the SBA loan and an active seller note determines whether the deal clears underwriting. The SBA loan payment is typically the larger of the two — often $150,000–$200,000+ per year on a $1.5M loan at current rates. Adding a $40,000–$50,000 seller note payment on top of that requires the business to generate substantial SDE to maintain adequate coverage.
The cleanest combined structure in practice: SBA at 90%, seller note at 10% on 24-month standby, buyer brings closing costs and working capital from personal funds. This structure maximizes leverage, satisfies SBA equity requirements via the standby note, and gives the business 24 months before the seller note adds to debt service. It requires a motivated seller, an SBA lender who accepts standby as equity, and a business that clears 1.25x on the SBA payment alone during standby.
Model Your Deal
The numbers in a seller note deal are interdependent in ways that aren't obvious from a term sheet. The rate affects the monthly payment. The term affects the annual debt service. The standby period determines when the note hits your DSCR. The SBA loan terms determine the baseline coverage. And the SDE determines whether any of it works.
Running this analysis manually — building out a full amortization schedule, calculating DSCR in each year, stress-testing at a 10% SDE haircut — takes 30–45 minutes per deal. In a pipeline where you're evaluating 10+ deals per month, that's not sustainable.
A purpose-built deal analysis tool runs the full model in under 60 seconds. Input the purchase price, SDE, SBA loan terms, seller note size, rate, term, and standby period — and get back year-by-year DSCR, annual cash flow to the buyer, and a flag on whether the structure passes or fails the 1.25x threshold at every stage of both loans.

How much seller financing is typical?
Seller notes most commonly represent 10–20% of the purchase price in SBA-backed deals, though the right amount depends on the seller's motivation and the lender's requirements. The full breakdown of typical note sizes and when sellers go higher is in the sections above.
What interest rate is normal on a seller note?
Seller note rates typically fall in the 5–8% range and are fully negotiable, unlike SBA loans. The rate benchmarks section above covers what's typical by note size and term — see the full detail below.
What is a standby seller note?
A standby note is a seller note on which no payments are made during a defined period — typically 24 months — allowing SBA lenders to treat it as equity rather than debt in the DSCR calculation. The full explanation of how standby vs. non-standby notes differ is in the sections above.
How does seller financing affect DSCR?
An active seller note increases your total annual debt service, which reduces DSCR — potentially below the 1.25x lender threshold. A standby note avoids this during the standby period. The DSCR implications of each structure are covered in detail in the sections above — see the full breakdown below.
Seller financing is most powerful when the terms — rate, term, standby period, and subordination structure — are negotiated with full knowledge of how they interact with SBA underwriting. Know the benchmarks before you propose a number. Model the DSCR before you agree to terms. And confirm the structure with your lender before you finalize it with the seller.
