Found a house, under contract, now what???

[Saidah Johnson]

Hello, Bigger Pockets family, 

I am in the process of buying my first investment property; now that I am in it, I realize that I have no idea what I am doing! There are so many forms, so many numbers, and so much stuff that I don't know. 

My question is, what are some of the things you wish you knew when buying your first rental property?
