I am a XXXX XXXX VA XXXX XXXX veteran. I am cosigned/paying for two separate student loans for my Son whom is attending XXXX  XXXX University in XXXX. I am unable to negotiate a lower interest rate. Nor am I able to make these loans not count so harshly against my credit score. I have done all that I can in dealing with Sallie Mae. I don't know what I don't know and I am really just trying to get the best advice and interest rate possible. Please advise The two loans combined exceed {$47000.00}
