Contributions to my Roth IRA with profit from flips?If unemployed

[Chris Melear]

I'm currently unemployed and have an open Roth IRA. I have just rehabbed and flipped my first deal. I wanted to know if Im able to make contributions (monthly when I was employed) to the IRA since I'll eventually be paying taxes on the profit. Also, how would I need to pay taxes on my profit in order to since I dont plan to open a company for myself. I only plan to rehab 3 to 4 a year.
