It would be best to speak to a seasoned cpa to address your tax concerns. 

I can't address your questions in detail.

@Kevin McKittrick how was LL going to address this?  

You have 1 property 1 address and 6 units. 

Keep in mind these are different products for different markets: Hosts is the former YourPorter product and bought out to address an entry level < 10-20 listing portfolio , Guesty for Pros is the big brother with more advanced direct booking website and advanced features for larger portfolios.

I would like to know if the Alabama LLC must be created as a subsidiary of my WY LLC since the business address/registered agent is in WY or I have to use an AL registered agent to create the AL LLC that is going to own and manage the property.

He said to give him my email address and phone number which I did.3 or 4 days went by.

Double check the names, address, loan amount, other contact information, etc A few important documents include: The closing disclosure, The deed of trust, The note, and The warranty deed.

Quote from @Christopher Rodriguez: I can't address everything in your post, but I can advise you to talk to other agents.

If you do own both units, well then you can always address any lease violations with your other tenant as well.
