The reason I would advise against doing this is if you consolidate your Federal Student Loans with your non student loan debt you will lost all of your Federal benefits you have on your Student Loans; for example, Forbearance, unlimited in school Deferment time, and your Federal Subsidies.

Have you taken out any new Federal Student Loans since you did your last Student Loan Consolidation? If you have you have in fact reconsolidate your Federal Student Loans by adding the new loans into your existing consolidation. The new rate you would receive would be based on a Weighted Average of your existing consolidation rate along with the rates on your new loans.
