I am wholesaling here in detroit and have been for the past 5 years i have not wholesaled pre foreclosure homes but wholesaling as a whole is pretty good here just have to know the areas to invest, i wish you much success my friend.
It's difficult but not impossible. The issue is that most people owe much more than what the home is worth. You can find a pre-closure in one of the "hot" markets but they're so competitive right now. But if you market directly to home owners you could get lucky. Just depends on where you want to spend you time and marketing $
