People who become wealthy wholesaling real estate are business geniuses. Fortunately, they're also generous, and willing to share their secrets with others. It seems that real estate entrepreneurship and philanthropy go well hand-in-hand. In fact, I just recently heard an interview on public radio that sparked my interest. Bruce Marks, a business mogul from New York, has started an entire nonprofit giant. His success is based on the idea that generosity can pay enormous dividends.
