license required?

[Danielle Hammond]

I am very new to all of this. I am only looking at a few duplexes / triplexes to purchase... renovate and rent out, with goals of turning it into much more. Once my money and equity is straight I want to start flipping. I am wondering if I should start looking into licenses or certificates... Can I legally start a rental without some sort of license??? I know all states are different, I am in Michigan. Any advice please :) :)
