One Set of Documents.
One Industry Standard.
What the ISDA Master Agreement did for derivatives, SFSB model documents do for seller finance. When every deal is papered the same way, every note is easier to underwrite, easier to service, and easier to sell.

The Standard Documents
Attorney-drafted, board-reviewed, and updated as law and practice evolve. Full forms are a member benefit.
Model Promissory Note
The industry-standard seller note. Standardized payment mechanics, interest and default provisions, prepayment terms, and transferability language drafted so the note is liquid — investable and assignable from the day it is signed.
Join to accessModel Personal Guarantee
A standardized, enforceable personal guarantee for seller-financed transactions. Clear recourse terms, waiver provisions, and financial disclosure requirements that protect the note holder without unfair surprise to the guarantor.
Join to accessModel Security Agreement
The standard collateral package for a seller-financed sale: granting language, UCC-1 perfection procedures, after-acquired property provisions, and remedies on default — consistent from deal to deal.
Join to accessModel Asset Purchase Agreement
A complete asset purchase agreement built for transactions where the seller carries a note. Aligns the purchase terms, representations, and closing mechanics with the note, guarantee, and security agreement so nothing conflicts.
Join to accessFor Sellers
A note written on the standard documents is worth more, because buyers of notes can underwrite it quickly and trust what is inside.
For Brokers & Advisors
Stop reinventing the deal file. Standard documents mean faster closings, fewer attorney hours, and fewer surprises in diligence.
For Note Investors
Uniform paper is investable paper. Standardized terms, guarantees, and collateral make seller notes a scalable asset class.
