First time member, long time lurker from Pittsburgh, PA

I am a 29 yr old living in the Pittsburgh area. I am interested in building a rental portfolio in creative ways since I just finished school and do not have a large bankroll to finance cash purchases (yet).

I have flipped two single-family houses with a partner in the past. I used those proceeds to get through school with no student loans. I am under contract on a duplex (2,1;2,1) that will be my residence for the time being. The rental income will cover the mortgage, I will be paying the taxes and building a working-capital account for the property (instead of paying rent).

I am intrigued by the BRRRR method and am looking hard into finding a way to get started there.
