If it is closer to 10% that nearly doubles your estimated cash flow.I know next to nothing about section-8 renters so I would really want to study up on that before jumping in.Maybe the most important question is what do you think you could get the property for?

That was my purpose of buying here, besides being where I live.I am glad to hear you think it's not too ambitious, but I will double check my numbers to make sure I'm not being unrealistic.

It sounds like this guy is trying to make some money by providing information that you can freely access here on Bigger Pockets.If you have no cash for down payment and credit is not perfect then yes, wholesaling may be a great solution.Always, always double check with the folks here when paying any sort of money out-of-pocket for tutoring, coaches, classes, courses, etc.

It's the rare deal or situation where an assignment or double close would work for me.
