Frequently Asked Questions
What is an acceleration clause in a promissory note?
An acceleration clause allows the lender to demand immediate repayment of the entire outstanding principal balance plus accrued interest if the borrower fails to make a required payment within the cure period.
What is the difference between a secured and unsecured promissory note?
An unsecured promissory note relies solely on the borrower's promise to pay and creditworthiness. A secured note is backed by specific collateral (such as real estate, machinery, or stock) which the lender can seize upon default.
What is the IRS Applicable Federal Rate (AFR)?
The AFR is the minimum interest rate the IRS requires private lenders to charge on family or private loans. If you charge less than the AFR, the IRS may treat the forgone interest as a taxable gift or imputed taxable income.
Can promissory notes be prepaid without penalty?
Standard notes generally allow borrowers to prepay principal early without penalty, which reduces total interest paid. Some commercial notes may specify prepayment penalties.
