I had about $55 remaining in my NASA FCU account, which I had never gotten around to closing. Most of that money was put in my account when I put up a fight over the change in the appraisal fee at settlement. I got a mysterious letter a few weeks ago that said I had closed my account. I called NASA to find out what happened. They said there is a $5 inactivity fee every month. My account was drained to $0, and then they closed it. Unfortunately, I get all of my statements electronically, and I haven’t bothered to log in any time within the past year, so I had no idea. This is definitely something you need to be aware of when you open an account. There may also be a minimum, above which, they don’t charge inactivity fees.
