It concerns me that you would consider combining your Student Loans together with other private loans. And are your Student Loans--Federal Student Loans?

If your Student Loans are in fact Federal Student Loans, combining private loans and the Student Loans together would cause you to lose all of your Federal Benefits that are attached to your Federal Student Loans. This includes your unlimited “In School” Deferment, your Federal subsidies, and your 36 months of Forbearance and Deferment if you ever need a temporary timeout on your monthly payments.

Also, your Federal Student Loan interest is tax deductible, which is another benefit that you would lose if you were to lump the two debt amounts together.

If you are concerned about improving your credit score I would suggest looking into the FFELP Consolidation Loan Program. Improving your credit score is one of the many benefits of this program, while at the same time allowing you to retain all your Federal Student Loan Benefits. For more information on combining your Federal Student Loan debt with other debt, please see the source below.

Good luck, I hope this helps!
