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.
