What key factors make a rental investment property a homerun?

[Corey Mills]

I am new to the investing world and trying to understand in full the verbage and key factors in being successful when it comes to investing in real estate. I have a decent savings, my credit score is over a 700 with only debt being a car loan, yet I feel loss and uncertain if i can make this happen successfully due to my lack of knowledge from being new. I am really interested in mutilfamily maybe a house hack to start. How to I calculate if there is a cash flow, if it is a good deal or not? I appreciate any information that is given. I really want to build wealth and let my money work for me.
