These loans are guaranteed by the Small Business Administration and because of this, they offer some of the lowest rates on the market as well as long repayment terms and the ability to borrow up to $5 million. Repayment ranges from 7 to 25 years, based on how you plan to use the money. SBA loans are best for strong-credit borrowers who have been operating for at least 2 years and who are willing to work on the long application process to expand their business or refinance debt.
