Assuming running a dual hose inverter portable AC isn't against the lease agreement it would probably pay for itself based on the power usage. Pretty neat hack regardless.

Why? A dual-hose portable is more efficient than a single-hose, but a PTAC should (in theory) be more efficient (and possibly quieter) on account of having the heat-emitting side of the cooling loop outside of the living space, which is closer to the ideal split system - though I suppose that advantage could be undermined by the unit's age and condition.
Portable ACs are generally less efficient than regular window ACs and PTAC units since the compressor is inside the room.
Yes, except for dual hose inverter ones.
There are also portable split systems like Midea Portasplit.
