You may still qualify for a student loan if you are able to add a co-borrower to the loan who has a positive credit rating. Qualifying for private loans is based on credit criteria established by each lender. Credit qualification criteria can vary by the type of loan, by whether the borrower is a student or parent, or by whether the loan is backed by a co-signer.
Some factors that can affect a loan approval include credit rating, length of credit history, verifiable income, and debt to income ratio. If your application is denied, you may reapply with a co-borrower to improve your application.
