My loan provider emailed me to cheerfully say that my student loans are deferred until May 2015. Except I didn't contact them to ask for that to happen.
Turns out, there's a clearinghouse that provides data to verify college enrollment. I'm in 2 graduate classes this semester, which puts me back in the 'current student' category. They put my loans in deferrment automatically.
It comes with a .5% drop in the interest rate and payments are optional. If I continue regular payments the loan will be gone before the deferrment ends. So, I guess I just got a surprise temporary loan modification. Not too shabby.
