Promissory note vs deed of trust vs mortgage?
Three documents, three jobs: one creates the debt, the other two tie that debt to the house.

The short answer
A promissory note is the promise to pay. It creates the debt and sets the payment terms. A deed of trust and a mortgage are security instruments. They do not create the debt; they attach it to the property so the lender can foreclose if payments stop. States use one security instrument or the other.
Key takeaways
- •The promissory note is the debt; the deed of trust or mortgage is the collateral paperwork that secures it.
- •A deed of trust involves a neutral trustee who holds a power of sale; a mortgage is a direct agreement between borrower and lender.
- •Which security instrument you sign depends on the state the property sits in, not on the seller's preference.
- •The security instrument gets recorded at the county; the promissory note usually does not.
- •In owner financing, the seller holds the note, so the terms inside it are negotiated with that seller and are not standard.
What is the short answer?
The promissory note is the loan. The deed of trust or mortgage is the leash that ties the loan to the house. A promissory note is a written promise to repay a sum of money. It names the borrower and the lender, the payment amount, the interest rate, the payment due date, the length of the loan, and what happens if a payment is late. If you sign only a promissory note, you owe the money, but the lender has no automatic claim on the property. A deed of trust or a mortgage fixes that. It is recorded in county land records and creates a lien. If payments stop, the lien is what lets the lender force a sale. A mortgage is an agreement between a borrower and a lender. A deed of trust adds a neutral trustee who holds a power of sale on the lender's behalf. In seller-financed deals, the seller plays the lender's role. How owner financing works walks through the full sequence.
- •Promissory note: creates the debt, sets rate and payment, signed by the buyer.
- •Mortgage: security instrument between borrower and lender, recorded as a lien.
- •Deed of trust: security instrument adding a trustee who holds a power of sale.
- •The note is usually held, not recorded. The security instrument is recorded.
- •Lose the lien and the lender has an IOU, not a claim on the house.
How does it work in practice?
In practice you sign the note and the security instrument at the same closing, and a title company or closing attorney records the security instrument the same week. The deed moves into your name at that closing. You are the owner from day one. The seller is now a lienholder, the same way a bank would be. You make payments to the seller or to a third-party servicer. Property taxes and insurance may be escrowed or may be your direct responsibility, depending on what the documents say. When the note is paid off, the lien is released and recorded as released. Owner financing is a common path for buyers who cannot document income the way a bank wants, including people searching owner-financed homes with no credit check or buying a home with bad credit. Note that a seller who finances may fall under the CFPB loan originator rule, which affects who can set terms and how.
- •Sign the note and the security instrument together at closing.
- •Record the security instrument at the county; keep a copy of the note.
- •Confirm in writing who collects payments and where proof of payment lives.
- •Confirm who pays property taxes and who carries hazard insurance.
- •Confirm how the lien release gets recorded when the note is paid.
What are the common mistakes?
The most common mistake is signing a promissory note without recording a security instrument, so nothing in the public record shows the deal exists. That hurts both sides. The buyer has no recorded proof of the arrangement. The seller has no enforceable lien. Another frequent error is a note and a security instrument that contradict each other on payment amount, maturity date, or late-fee terms; courts read both, and conflicts cause fights. Buyers also skip a title search and inherit liens they never saw. Some assume a land contract or a rent-to-own homes agreement is the same as a note and deed of trust. It is not. Under a land contract or lease-option, the deed typically stays with the seller until later. A third mistake is ignoring the ability-to-repay rules in Regulation Z, which can apply to seller-financed loans and shape how a note must be underwritten and structured.
- •Signing a note with no recorded security instrument.
- •Note terms and security instrument terms that do not match.
- •Skipping the title search and the closing attorney or title company.
- •Assuming a land contract gives you the same position as a recorded deed.
- •Not knowing whether the note has a balloon payment and when it comes due.
What varies by state or by seller?
The security instrument itself varies by state. Some states use deeds of trust almost exclusively. Some use mortgages. A few use both, and some use other instruments entirely. That choice drives foreclosure procedure: deed-of-trust states often allow a non-judicial foreclosure through the trustee's power of sale, while mortgage states more often require a court process. Timelines, notice requirements, reinstatement rights, and whether a lender can pursue a deficiency after a sale all differ by state. Some states also regulate how many seller-financed loans a person can make in a year before licensing rules apply. Separately, everything inside the promissory note is set by the individual seller and is negotiable: the interest rate, the down payment, the length of the loan, whether there is a balloon, whether prepayment is allowed, and how late payments are handled. Nothing in owner financing is standard or offered across the board. Each seller writes their own terms.
- •Deed-of-trust states versus mortgage states, and a few that use both.
- •Judicial versus non-judicial foreclosure, and how long each takes.
- •Whether a deficiency judgment is allowed after a foreclosure sale.
- •State licensing thresholds for sellers who finance more than occasionally.
- •Rate, down payment, term, balloon, and prepayment: all set by the seller, all negotiable.
Common questions
- •Do I actually own the home if the seller holds the note?: Yes, if the deed transfers to you at closing and the seller records a deed of trust or mortgage as a lien. You hold title. The seller holds a secured debt against the property, the same position a bank holds. This is different from a land contract or lease-option, where the deed typically stays with the seller until a later date.
- •Does the promissory note get recorded at the county?: Usually not. The note is a private contract between the borrower and the lender, and it is normally held rather than filed. The deed of trust or mortgage is what gets recorded, because recording is what puts the public on notice of the lien. Keep an original or certified copy of your note somewhere safe.
- •What happens to the deed of trust when I pay the loan off?: The lender releases the lien and that release is recorded at the county, which clears the security instrument off the title. In a deed-of-trust state the trustee typically signs a reconveyance. Ask before closing who is responsible for recording the release and how you will receive proof it was recorded.
- •Can a seller use a mortgage in a state that normally uses deeds of trust?: Sometimes, but it is uncommon and it can change how foreclosure works. Local practice exists for a reason, and lenders, title companies, and courts in that state are set up for the instrument the state typically uses. A closing attorney or title company licensed in that state should decide which instrument the deal uses.
- •Who should prepare the note and the security instrument?: A closing attorney or title company licensed in the state where the property sits. Template documents pulled off the internet frequently conflict with state rules on notice, foreclosure, and disclosure. Seller-financed loans can also fall under federal rules such as the CFPB loan originator rule and Regulation Z ability-to-repay requirements, which affect how the note must be written.
