As far as the LLC - I would strongly suggest you speak with an attorney that does private lending work regularly to ensure that the loan docs will be valid and enforceable. 

So I'm wondering how are these people able to get on the Airbnb platforms to list their properties with the strict paperwork requirement. 

Any suggestions?

We as a firm have investors working with us who have rental properties all over the US big and small.Finding a real estate-focused tax professional and one who can help with advisory and grow with you would be my suggestion to focus your efforts on finding.

I would suggest that you focus on building your team.

I'm wondering if I purchase the uncle's single wide trailer, rehab it, move him back in, if there is some sort of government assistance I could receive. 

If you have any suggestion or advice please feel free to share them with me. 

As our rental income is building up in the bank account now, we are wondering how to finance the next one.

This is wonderfully helpful, thank you! 

I'm wondering if there are any lenders that would still allow 1 year tax returns.
