In short
A co-signer is someone who agrees to be equally responsible for a loan repayment. For an SBA loan, they are signing on with you, not just guaranteeing your debt.
If your personal credit or income alone isn't strong enough, a lender might require a co-signer. This person becomes a co-borrower, meaning they have the same legal obligation to repay the loan as you do. Ensure they understand the full implications before involving them.
