USAA offers a "Career Starter Loan" to cadets/mids in ROTC or SA's. You can find more information
here.
The low interest rates for SA cadets/mids is what draws many cadets in. Its easy to think "oh i'll put this in a fund that averages a 10% return and make profit!! This is a great way to start my career" Others will buy a 2021 Jeep or Mustang with the loan.
Many advise against it because of the UNNECESSARY risk that is involved. Here is a
great article I found that advises against it.
However, some people can make a profit off of it IF they invest smartly and conservative. Here is
an article on how it could be used smartly. (This article is outdated and mentions CD ladders which are essentially non-existent anymore. Keep that in mind)
Taking out the loan should depend on if you need it. If you want to take it out to invest, that's on you. But do a lot of research before hand and make sure you have plan for what you are going to do with that money. It's possible to make a profit but its also possible to lose all that money. There's a common saying of "its impossible to build wealth when you are in debt". If you take out that loan, you will be in debt. Would you rather be in debt by choice or debt free? That answer will depend on the person.
