When they move out they'll rent the SFH for at least $3500.

Another option is to split the cost based on the number of occupants in each unit but this also means you'll need to adjust the charges as tenants move in/out, so it requires more work and I wouldn't recommend it.

It seems flippers that do HML start out with about this on their smaller deals, no?

Local REIA groups and meetups (check Meetup.com or BiggerPockets) are excellent for connecting with both new and experienced investors.I’d be happy to grab coffee and chat about the market or share insights.

 @Sheri Fluellen, I completely undersand and I hope it works out for you.

I've also consulted with a lawyer but wanted to check if anyone else has ideas about how best to go about this. 

If so, does anyone know of a lawyer, who can sort this out with a quick phone call to Airbnb?  

Anyone can live anywhere they want if they have the money, and sometimes houses are bought and then rented out without much background checking on the people moving in.

Because instead of collecting one rent check per month, you’re collecting multiple payments from different tenants.

I'm not going to through out names, but there are companies that only take $500 at closing from an agent.
