Preparing for my house hack (questions)

[Marshall Barta]

So since August I've been looking into house hacking and talking to one of my friends who does rentals. I moved into my gf's family's home in October so I could work and save up money. My goal is sometime in May, and I'm projected to have $15-20K by then. I still have a lot to learn but I figured the sooner I jump in, the better. I'd like to purchase a quad-plex but to my understanding, I should take a good deal when I see one whether that's a duplex or triplex even. I'm currently trying to figure out the best way to calculate cash on cash return, as I have some time to find opportunities and would love to cash flow positive off the bat. I just feel like there's a lot to account for and I want to make sure I don't blindside myself. I'd be grateful for any advice you guys would like to share, thank you!
