What Is a Promissory Note in a Business Sale?
A promissory note in a pest control business sale is a legally binding agreement in which the buyer promises to pay the seller a specified amount over time, with interest. It's the formal legal document underlying what's informally called a 'seller note' or 'seller carry.' The note specifies the principal amount, interest rate, payment schedule, maturity date, and — critically — the remedies available to the seller if the buyer defaults.
Typical Terms in Pest Control Seller Notes
Pest control seller notes typically run 3–7 years with monthly payments. Interest rates range from 4%–8%. The note is subordinate to any SBA loan — meaning if the buyer defaults and there's an SBA loan in place, the bank collects before you do. Some seller notes include a balloon payment at maturity. Others amortize fully. The specific terms are negotiable and should be documented clearly in the purchase agreement before LOI acceptance.
- Principal: typically 10–25% of purchase price
- Interest rate: 4–8% annually (5–7% most common)
- Term: 3–7 years
- Payments: usually monthly
- Subordination: typically subordinate to SBA/bank debt
- Collateral: often secured by the business assets you just sold
Securing Your Seller Note
A seller note should be secured by collateral — ideally the business assets being sold. The security agreement gives you the right to reclaim assets if the buyer defaults. In practice, collecting on a defaulted seller note is difficult: the business may have been stripped of value by the time you're able to act, and your subordinate position behind the bank means you may recover little. The best protection against default is proper buyer qualification upfront — verified financial capacity, industry experience, and SBA pre-approval before accepting any note.

Tax Treatment of Seller Note Payments
Seller note payments you receive have two components: principal (return of your deferred sale proceeds) and interest. The interest is taxed as ordinary income — not capital gains. If you elected installment sale treatment, the principal payments are taxed as capital gains in the year received, at the applicable rate. Without the installment sale election, the full gain is recognized in the year of sale even if you haven't received all the cash.
When to Decline a Seller Note
Seller notes should be declined when: the buyer has insufficient experience or financial reserves to weather operational challenges, the SBA lender's underwriting suggests the deal barely passes the minimum DSCR, the note represents more than 20% of total proceeds (your downside risk is too large), or you need all-cash at close for personal financial reasons (retirement, estate, medical). If the buyer can't close without your note and you have alternative buyers willing to pay all-cash, the note should be negotiated out of the deal, not accepted.
