Promissory note

What does "Promissory note" mean in real estate?

A promissory note in real estate is a written, legally binding promise by a borrower to repay a specific sum of money to a lender under agreed terms. Think of it as the loan’s IOU: it records the principal, interest rate, payment schedule, maturity date and remedies for late or missed payments. While a mortgage or deed of trust secures the loan with the property, the promissory note is the actual “promise to pay” the debt.

Key components

How promissory notes are used in real estate

Promissory notes appear in nearly every type of home loan transaction:

Real-world examples

Why promissory notes matter to homebuyers

The promissory note is one of the most important loan documents you’ll sign because it defines your legal obligation to repay. If a borrower defaults, the lender uses the note as evidence of the debt and the basis to pursue collection or foreclosure through the associated mortgage or deed of trust. Even when the security instrument gets more attention (because it affects the property), the note is the core debt instrument.

Practical tips

In short, a promissory note is the legal promise to repay in virtually every real estate loan. It protects lenders by documenting the debt and protects borrowers by clearly stating the terms they’ve agreed to. Understanding the note helps you know exactly what you owe and what can happen if payments aren’t made.
