Does anyone have any experience with the Student Loan Repayment Program?

It requires effort by the Soldier, if that is what you mean by "headache".
Where Soldiers fail and run into the headache:
1. The Soldier is responsible for making monthly payments on their own student loans, the SLRP pays out annually, but will not pay out that year if the loan is in default that year.
2. The Soldier is responsible for updating or confirming the lender information for payment no less than 90 days prior to scheduled annual payment. (Student loans get sold, just like mortgages and car loans).

SLRP does not "pay off the loan", it pays as much as 15% of the original loan total, once a year for every year of the contract.

The biggest issue to be aware of using student loan repayment is that the money will still be taxed as income. That means that your $40,000 student loan repayment well actually total around $30,000 in cash payments to you
