Getting Started in REI

[Deja Foster]

I was on the 90-day challenge webinar yesterday. It really inspired me to get started. I am not financially destitute, but my cash flow is tight. I just got approved to drive for Uber and Lyft so I plan on using driving for dollars and MLS to accumulate some leads. I ideally would like to house hack as I currently live in a 4-plex and think it would be helpful for me on my REI journey.
 

While I could definitely scour this robust site for details on the questions I am about to ask. I wanted to see if there are optimal credit scores (its fair right now) and cash positions (only about $800 saved up) for financing a deal. I know there are different ways to finance a deal per the real estate for beginners book, but how do you vet those deals? I am also trying to gain a better understanding of the content I should focus on to get my first deal done in the next 90 days.
