Can I set up my account with my property manager in my LLC name so that all income and expenses go through the partnership even if the LLC doesn't own the rental? 

Do your research, set clear goals, and decide on a strategy that works for you.

Example of overcharges included* $300 for cleaning windows and cabinets after entire house was professionally cleaned* $80 to replace HVAC filter after entire HVAC system was replaced* $700 for a small list of punch items - 2 door stops, raking backyard, removing satellite dish in backyard and trimming bushesAfter terminating relationship, owner decided to send a termination charge for $450 (contract does stipulate it) - even though the company has not done squat and never placed a tenant and already charged so called 'set up' fee of $300..

Have a weird layout property where the front door is on the 2nd floor and there is a set of wooden stairs to get up there.

@Stuart UdisYou forgot to have the Wyoming LLC owned by a Delaware holding company that has the asset then put into a land trust.Then seek 100% financing because you are broke from spending $10,000 setting up this corporate structure to protect the zero assets you have.

Perfect, sounds like the commercial side will be all set. 

Perhaps setting up a private FB group and inviting those in.  

Otherwise, just buy a home with no HOA (if you want the option to do MTR and STR and not risk them setting rental rules) with as many bedrooms as makes sense for the numbers.

They have claimed their thermostat changes temperature (ex. they set it at 72 before bed and wake up and it's 65 degrees in the morning.) 

Yes, that is exactly what they are promising, very hands on, and helping you set up everything from soup to nuts.
