Open the promissory note. This document records the borrower's promise to repay the loan. It states terms such as the amount owed, interest rate, and payment requirements. Place the note beside the mortgage or deed of trust. The note addresses the debt and repayment. The security instrument connects the obligation to property securing it. Reading one does not replace reading the other. The documents work together, but their functions are different. Match the exam question to the document's job instead of treating all loan paperwork as one instrument. Quick check: are the promise to repay and the pledge of property the same function? No. The note documents repayment; the security instrument provides the property security.
