Frequently Asked Questions

SBA (Small Business Administration) loans often have variable interest rates tied to the prime rate, though fixed-rate options are available. They generally offer lower rates than conventional business loans.
In most cases, the interest paid on a business loan is fully tax-deductible as a business expense, which lowers the effective cost of the loan.
Some commercial loans require smaller monthly payments for a set period, followed by a large "balloon" payment to pay off the remaining principal at the end of the term.
