This might be old news to some, but about two years ago the changed their membership requirements. Prior to Feb 2017, you had to be either still active/reserves or retired to start a new membership. I had wanted to get a car loan from them prior to that and been told they were looking to expand. I had no reason to check again until today and found the above info out. They've got some extremely competitive rates on certificates of deposit at the moment.
I'm starting to migrate some of my banking and insurance away from USAA. Checking paying .01% and Savings paying .15% has been pushing me move to credit unions and certificates for most of my emergency fund and other "cash" savings. I've been using Teacher's Credit Union locally (which, despite the name, doesn't require you to be a teacher) but NFCU is beating them on short term certificates.
