I posted on this topic numerous times, I would use a 1065, in almost every case I want the 1040 to be from flowthroughs. I might even give a spouse or child .0001% just to get it off of the 1040. High 1040's have a higher rate of audit, and an auditor will make you prove expenses aren't personal. Having it as a 1065 makes it easier down the road to add partners or transfer percentages each year to children. If any legal issues occur you only have to supply the 1065 to a tenant for example and not the whole 1040 which even though protected, shows all your other income or assets. When your loving couple gets divorced, its much easier to trace the distributions. Since the amount of accounting you would have to do is the same whether on an E or 1065, the only extra prep cost is the actual filing out of the form.
