Do PLUS loans have a grace period?

PLUS loans do not act like other federally backed loans in many instances.  For example you have to apply for them based on credit (whereas a denial for a federal loan is almost unheard of unless you go over the aggregate amount).

Another big difference is in the grace period.  PLUS loans do not have a grace period.  They will enter repayment as soon as the loan is fully disbursed and after the borrower is no longer enrolled as at least a half time student.

But there is a solution.  You can apply for a Post-Enrollment Deferment.  This acts like a grace period and lasts for six months after the borrower or student the loan was taken out for graduates, withdraws, or stops attending at least half time.

For a Graduate Student this should be requested near repayment, typically 60 days.  For a Parent PLUS loan when you are requesting your Parent PLUS In-School Deferment you can request your Post Enrollment at the same time.
