Student loans are either private or government
If government , there are income based repayment plans where the balance can be forgiven after 10 years of QUALIFIED payments . Navient and Fedloan are some of the biggest . Atypical that the servicing is sold and the ownership of the loan is NOT sold- the federal government owns the loan
if private loan , interest rate can be lower but there is normally no income based repayment loan, you owe the entire loan balance . These loans can be bought and sold by the servicer and the investor
