What Is Promissory Note?
When you get a mortgage, you sign two key documents: the promissory note (the promise to pay) and the deed of trust (the lien on the property). The note defines the deal: principal amount, rate, term, monthly payment, acceleration clause (what happens if you default), balloon payment (if any), and prepayment penalty (if any). The deed of trust says: if you don't pay, the lender can foreclose and sell the property. The note is the obligation; the deed is the security. Seller-carryback and creative financing deals use notes too—the seller holds the note and can sell it to an investor. Read your note. It's the contract that governs your payment obligation.
A promissory note is a written promise to repay a debt. It sets out the amount borrowed, interest rate, payment schedule, and the borrower's obligation to pay. It's the "IOU" that creates the personal obligation; the deed of trust secures it with the property.
At a Glance
- What it is: Written promise to repay a debt
- Contains: Amount, rate, term, payment schedule, default provisions
- Paired with: Deed of trust (secures the note with the property)
- Transferable: Lenders and seller-carryback holders can sell the note
- Governs: Your obligation to pay; acceleration and balloon terms
How It Works
Note vs deed of trust
The promissory note is the debt instrument. It says: "I promise to pay $X at Y% interest over Z years." The deed of trust is the security instrument. It says: "If I don't pay, the lender can sell the property to satisfy the debt." You need both. The note creates the obligation; the deed gives the lender a way to enforce it.
What's in the note
- Principal: Amount borrowed
- Interest rate: Fixed or variable
- Term: 15, 20, 30 years, or custom
- Payment schedule: Monthly amount, due date
- Default provisions: What constitutes default (non-payment, breach of covenants)
- Acceleration clause: Lender can demand full balance upon default
- Balloon payment: If applicable, when the full balance is due
- Prepayment penalty: If applicable, fee for early payoff
- Late fees: Amount and when they apply
Note holders and servicing
The note can be sold. When your lender sells your loan to Freddie Mac, Freddie owns the note. The servicer (who collects payments) may be the same or different. You still owe the same amount to the same terms. The note follows the loan; the holder can change.
Seller-held notes
In seller-carryback and purchase-money mortgage deals, the seller holds the note. They receive your payments. They can sell the note to an investor—you'd then pay the new holder. The note terms don't change; only the payee does.
Real-World Example
Denise buys a fourplex in Oklahoma City with seller-carryback. Purchase price: $220,000. She puts $50,000 down. The seller carries a promissory note for $170,000 at 6% for 20 years. Payment: $1,218/month. Balloon payment at year 7: she must refinance or pay off the ~$145,000 balance. The note includes an acceleration clause: if she misses two payments, the full balance is due. No prepayment penalty—she can pay early. The deed of trust secures the note with a lien on the property. Denise makes her payments to the seller. In year 5, the seller sells the note to a local investor. Denise gets a letter: "Send future payments to XYZ Investments." The note terms are unchanged; she just has a new payee.
Pros & Cons
- Clear, written record of the debt obligation
- Governs payment terms, default, and remedies
- Transferable—enables secondary market and seller-carryback liquidity
- Paired with deed of trust for secured lending
- Binding contract—you're obligated to the terms
- Acceleration and balloon can create sudden payoff requirements
- Note sale means a new payee—less flexibility than dealing with original lender/seller
Watch Out
Read before you sign: The promissory note is the core contract. Understand the acceleration clause, balloon payment, and prepayment penalty. Don't assume—verify.
Balloon date: If your note has a balloon payment, calendar it. You must refinance or pay off by that date. Missing it can trigger default and acceleration.
Note sale and modification: If the note is sold, the new holder may have different policies on modifications, forbearance, or payoff. The terms don't change, but the relationship might. Get everything in writing.
Lost note: If the lender or note holder loses the original note, it can complicate foreclosure and payoff. They may need to execute a "lost note affidavit." Rare, but it happens. Keep a copy of your note.
The Takeaway
The promissory note is your written promise to repay. It defines the amount, rate, term, and what happens if you default. Paired with the deed of trust, it's the foundation of every mortgage and seller-carryback deal. Read it, understand the acceleration and balloon provisions, and keep a copy. It's the contract that binds you.
