I see recommendations to contribute only up to the company's match. I've seen other recommendations that one should contribute as much as possible or even max it out if you can afford it. What are your thoughts on the 401K or even an IRA? Good way to invest or do you prefer other investments? I have a relative that recently bought a rental property but I'm not sure that's really a good investment anymore as quality renters seem much harder to come by now than they were decades ago.
