Next step after a few SFHs

[Jonathan Roveto]

Hi everyone! I've been purchasing and renting out a few SFHs in my area (4 at the moment). I'm thinking that I may get a couple of more, but I also want to know what the next step tends to be for other people out there. Do people tend to keep buying up SFHs? Invest more in multiplex  properties? Try to move up to small apartment complex? I see at least a few complex in my area that can't be more than 8 or 12 units. How profitable are such units, and at what point can a single person start getting into that kind of game (or is this something people tend to go in on as a group)? I would love to hear what you all have to say!
