THE SHORT ANSWER
A seller note turns part of the price into a credit exposure. Specify the debtor, principal, interest, payment schedule, maturity and security, then reconcile the note with senior debt and the purchase agreement. Rates and terms are negotiated. A filing, guarantee or higher nominal price does not assure collection.
Write the payment mechanics explicitly
Identify the legal borrower, principal, interest convention, first payment date, amortization period, maturity and any balloon. State whether interest accrues during a deferral, how rounding works and how prepayment is treated. A quoted monthly payment is incomplete without these inputs.
Ask for an amortization schedule and compare it with the purchase agreement’s stated deferred consideration. Keep any earnout separate: its payment depends on a defined outcome, whereas a note is a debt obligation subject to its terms. Do not describe an earnout as a guaranteed note payment or assume a later loan will refinance a balloon. Verify the complete structure before relying on it.
Connect the note to security and priority
Ask counsel to identify the collateral owner, collateral description, existing liens, required security agreement, appropriate perfection method and priority arrangements. The model UCC attachment rules illustrate that collateral rights and documentation matter; they are distinct from filing alone.
(UCC section 9-203: attachment and enforceability)Illinois section 9-310 provides a filing rule with exceptions. Some collateral can require a different method, and the governing jurisdiction must be determined.
(Illinois UCC section 9-310: filing and exceptions)A personal guarantee creates potential recourse under its terms, not guaranteed liquidity. Determine what the guarantor owns, competing obligations and the limits of recovery. Real estate security needs its own legal analysis.
Resolve senior-lender restrictions before signing
Obtain written lender review of payment, subordination, enforcement and setoff provisions. Under current SBA SOP 50 10 8.1, qualifying seller debt counted toward injection is subject to the limited-source aggregate cap and full standby for the 7(a) loan term, not a generic 24-month payment holiday.
(SBA SOP 50 10 8.1, Appendix 15: changes of ownership)Have the lender distinguish that qualifying injection note from other proposed seller debt and identify every applicable condition. Do not assume every seller note has identical treatment. An intercreditor agreement can affect collection even when the borrower remains obligated. Reconcile any seller employment, retained equity or contingent payment with the actual SBA transaction category.
Define reporting and problem-handling
| Term | Question to resolve |
|---|---|
| Reporting | Which records, delivery dates and access rights? |
| Covenants | Which defined tests apply and how are breaches measured? |
| Default | What notices, cure rules and remedies are permitted? |
| Setoff | Can claims against the seller reduce note payments? |
| Prepayment | What amount settles principal, accrued interest and fees? |
Model collection delays and downside operating results before accepting the note. Keep enforceability, priority and payment capacity as separate questions. Use the seller financing overview to consider tax and cash requirements, and maintain the final executed documents with the payment schedule. No current market interest-rate range, buyer-pool multiplier or standard cure period is assumed.
Owner questions
Does a UCC-1 alone create a complete secured loan?
No. Collateral rights, security documents, applicable perfection requirements and priority all need review.
Is every SBA seller note payable after 24 months?
No. Current qualifying injection debt requires full-term standby, and other seller debt needs lender-specific review.
Must a seller note include a balloon?
No. Payment structure is negotiated and must fit actual liquidity and lender conditions.
