Dave Ramsey vs my own real estate investing

[Phillip Gonzales]

Good afternoon all so I have been taking Dave Ramsey financial classes over the last couple weeks. If anyone hasn't heard of him please look him up, but anyways my question is his beliefs and what he teaches on is about paying off debt, saving then invest as well as not financing anything and just paying cash. I wonder how many of you started out with an actual emergency fund and or paying off all debt before investing? 

As well, how possible is it to do cash purchases vs loans..FHA conventional etc? I am starting off with my first property soon just trying to gather as much info
