When starting BRRR is it best to buy with cash or finance?

[Kyle Phelps]

I am reading through the BP BRRR strategies book right now. I plan on jumping in head first into real estate investing two months from now. While reading through the book it mentions that buying your first brrr property with cash is ideal. I have always heard that you should invest as little as possible. I dont have a problem buying my first property with cash, I just want to make sure I'm doing the right thing. What are your experiences?
