Short answer: Seller financing means the seller accepts a promissory note for part of the purchase price. It can reduce cash at closing and align incentives, but terms, collateral, payment priority, default rights, standby requirements, and interaction with senior financing must be negotiated carefully.

Model the Full Capital Stack

Combine senior debt, buyer equity, seller note, fees, working capital, and reserves. Calculate payment timing and debt coverage under base and downside cases.

Key Note Terms

  • Principal, interest, amortization, maturity, and balloon
  • Payment timing and prepayment rights
  • Collateral, guarantees, and subordination
  • Default, cure, offset, and acceleration provisions

Alignment Is Not Verification

A seller note can signal confidence and create post-close cooperation, but it does not prove earnings or remove the need for diligence. An overleveraged deal can fail even when the seller carries paper.

Coordinate with the Senior Lender

Institutional or SBA-backed financing may impose rules on seller-note payments, standby, security, or subordination. Confirm eligibility before treating the note as committed funding.

Frequently Asked Questions

How much seller financing is normal?

There is no universal amount. It depends on the deal, lender, buyer equity, seller objectives, and risk allocation.

Is seller financing the same as an earnout?

No. A seller note is generally a debt obligation; an earnout is contingent on defined future performance or events.

Can seller financing improve approval odds?

It may help the capital structure, but lenders apply their own underwriting and eligibility rules.
