They have 6 figure jobs and just want to collect rental income and move on from their job ASAP. 

You can collect a finders fee. 

However you've collected your fee since its easy to direct buyers how to buy the homes in markets where there's no barriers and hundreds are available at any given time, and the buyer feels like they accomplished something despite sitting on real estate that will never generate real gains. 

I recently evicted a tenant for non-payment and non-confirming the lease rules, and would like to file collections against her.

You need to make sure that how the money is collected is 100% collected prior to them putting a single door in the door.  

We’ll also collect rent and pay expenses via our LLC and its new respective bank account(s).  

Some of these boards have members that are total BS and some have members who are really impressive.

Realistically it's going to be difficult for you to actually collect the remaining rent amount if the tenant refuses.

If you do a risk assessment of the area, property and likelihood that you can collect rents easily, then you should be good.I have about 25000 saved up and I'm living at home for free how much of that should I spend on a property or save. 

It's impressive that you turned a bank-owned property into a thriving Airbnb.
