Advice on where/how to start in Real Estate Investing - Step 1

[Kaylyn Schroka]

What recommendations does anyone have on where to start/learn about real estate investments, specifically in single-family and multi-family rental homes?

I live in Michigan, and don't have any experience in real estate outside of currently renting a home for myself. Not sure if I should take classes, get a Real Estate License, get a realtor, etc. Would love to hear experiences or advice anyone may have.
