I’m not sure what your state requires under landlord/tenant on a “separate “ account, but it really is cleaner to keep them separate, but if you reconcile each month and show those funds there, it should be ok.

Hello all, we are so excited to close on our first StR/ MTR that will be a complete gut job. The property is a 3/2, in a great family friendly area and very close to a commuter college. It’s in very bad condition righ...

If you find a cleaner to manage it life is easy but it's also difficult to maintain because you lose them to others that can provide more consistent work.  

I've never had a temperature complaint because our system puts out so much cold air that most people (including myself, who loves AC) are freezing at 72 degrees, because the thermostat is upstairs so the system will come close to running non-stop at 72.

If you can hire a trustworthy cleaner to switch the sheets and do a quick clean then it's worth it, especially because you can charge a cleaning fee.

I tell her she should get a contract, which my mother tells me she can go to Walmart and get a contract and that will settle that, and my relative left his entire home furnished, so imo that makes more sense to air bnb but I’m not expert  I’m wondering are there anything to look out for or avoid a migraine with?

If they're unwilling or unable to do so, take that task on yourself.Assuming you can clear the air, let them continue doing what they've done well for you in the past - property management.

If not, then ask that the boxes go in the middle of the room, so that the inspector has access to the walls (also if there is an active leak, the last thing you want is a bunch of cardboard boxes against the wall impeding air flow).An inspector will not move anything for the inspection and they will miss things because nothing is 100% no matter who does it. 

If it does require something in person, maybe your cleaner can be paid to do it?

A great cleaner is the key.
