From a tax standpoint, no advantage, but you may actually increase your tax liability on your federal return by converting passive income to active income.
However, transferring the property management from the LLC management to a seperate entity may provide some level of additional protection. in the event that the manager does something stupid and gets sued, it’s better to have the management co (with no assets) sued rather than the entity that owns the property.
it’s a small difference, but I at least wanted to point it out.
