What about buying a property and AirBnbing a room or a portion of the house?

An S-Corp is not a one-size-fits all, this is the gospel kind of a solution. 

Should I set up routing rules so the owners get a direct payout from AirBnB and I get a direct portion of their fee?

You’re adding an asset you can be sued for and removing the stepped up basis in case of death and who knows what happens with the primary home tax exemption In regards to your portion. 

For the analyze deals portion, there are a lot of tools BP offers to help you analyze, try doing 1-3 a day to start for a month in the area you really want to look into.

Be prepared to spend (depending on size) $500-1000 for an inspection report.

Take in consideration the size of the property, etcThank you,Aviv
