My next step after first house purchase

[Steven Bays]

I purchased my first house which is a duplex and I love it but I am hungry for more. Without a mentor here in cincinnati, I feel that quads up to apartments is something I would really like. I assume and read numerous posts that I need to build up cash flow but am I limited to flipping? I am interested in seeing how much money I need to keep moving forward. How have some of you got your start. Should I get a second job to get more money?
