Is real estate wholesaling still profitable?

[Clarence Dixon]

So last year I started giving real estate wholesaling a go but because of personal issues I ran out of money and had to attend to other things. Ive got my situation back together and im ready to give it another go but ive heard people saying that its tough to make a profit because marketing is so expensive in most cities. Is anyone out there in a mid size to large market making profit soley from real estate wholesaling?
