Michael, it depends upon a lot of factors.For people involved with REI, it depends upon what you want to do with the business as there are different tax rules based on type of entity.For holding rentals, I generally recommend an LLC if you are setting up an entity at all.For flipping and development, I generally recommend an S corp.For wholesaling, my recommendation would depend more upon your specific business.
