Guarantor
A party who promises to pay a debt if the primary borrower fails to — providing a backup source of repayment without being the original obligor.
A guarantor is a person or entity that agrees to repay a debt if the primary borrower does not. The guarantor's promise is typically set out in a separate guaranty agreement that accompanies the promissory note. Unlike a co-maker, who is a primary obligor liable from the start, a guarantor's obligation is usually secondary — it kicks in only after the borrower defaults. A guaranty is a common credit enhancement on owner-financed and commercial real estate notes, and its strength directly affects what a note is worth.
Types of guaranty
- Guaranty of payment — the holder can demand payment from the guarantor as soon as the borrower defaults, without first suing the borrower or foreclosing. This is the stronger form for a note holder.
- Guaranty of collection — the holder must first attempt to collect from the borrower (often including exhausting the collateral) before turning to the guarantor.
- Limited vs. unlimited guaranty — a limited guaranty caps the guarantor's exposure (a dollar amount or percentage); an unlimited guaranty covers the entire debt plus costs.
- Personal guaranty — common when the borrower is an entity (such as an LLC); an individual principal personally backs the loan, putting personal assets at risk.
Why a guaranty matters when you sell a note
A solid guaranty adds a second source of repayment, which lowers the risk a note buyer assumes. When a borrowing entity has thin assets, a personal guaranty from a creditworthy principal can be the difference between a thin offer and a strong one. During due diligence, a note buyer reviews the guaranty's terms (payment vs. collection, limited vs. unlimited), confirms it was properly signed, and assesses the guarantor's financial strength. A note backed by a wealthy, fully enforceable guarantor commands a higher price; a guaranty that is narrow, expired, or unsigned adds little value.
Guarantor vs. surety
The terms are close. A surety is generally primarily liable alongside the borrower — the creditor can pursue the surety immediately — whereas a classic guarantor is secondarily liable, stepping in after the borrower defaults. The exact wording of the agreement and state law control which applies.
Example
An investor's LLC buys a small commercial property with seller financing and signs a $400,000 note. Because the LLC is newly formed, the seller requires the investor to sign an unlimited personal guaranty of payment. Two years later the seller sells the note. The buyer sees that, on top of the property collateral, a financially strong individual personally guarantees the full debt — so the buyer offers a smaller discount than it would for an entity-only note.
