I operated in Baltimore city for less than a year.

where do you operate? 

There are also additional costs of operating and maintaining an LLC, like separate bank accounts, annual report filings, tax filings, etc.2.

This is totally contrary to the way most wholesalers can operate.5.

A car forum that I'm a part of, and I know the owner of the forum, told me that the dedicated app required constant work and updates as phones and operating systems changed. 

-The mention of syndication being less risky than HML...I'd suggest it is more risk, possibly much much more since you don't know whether you are good or bad at vetting the operator right now.

To have a successful STR I HIGHLY recommend listening to this episode of a podcast: https://podcasts.apple.com/us/podcast/on-the-market/id161508...Once you listen to this, and any highly involved STR operator will agree, you will find a lot of the fundamentals are lacking in Kissimmee or you have to have deep pockets to hit those.I won't spoil the episode, but if you listen to it (and anyone out there that does) feel free to DM me afterward and I'd be happy to talk details tailored to your situation on if you're on the right path or maybe I can help.

Does anyone represent a wholesale lender or is a broker that knows of a lender who finances commercial (multifamily) properties that operate as AIRBNBs?

Most will have large scale marketing engines where they spend thousands or tens of thousands a month, and operate or license time in call centers.

Would that lower our tax liability from other income we receive or no because this is purely RE and not an operating business?
