My main question is, should I invest in my company's plan? I'm quasi about tying up some of my income for low returns when for example I can put that portion to better use in real estate investment or better stocks.

I also am planning on a career change in the next month, what if my new job doesn't have a plan, where do I put the $ in my current 401k?

What if I decide to go in business for my self, what happens to the current 401K?

Thanks for all your help!
