I would walk thru the purchase process in Norway and see if you can do a quick resale and also make sure it is legal or you can’t be sued for tying up the property from the owners selling.  

I'm not a huge fan of the 3 way split - if the current owner is going to retain the properties, but you are going to rehab and manage them, and then you have another person fronting the money to fix them up.  

I’m wondering how I should go about starting this whole process?

It cost more and takes more time for housekeeping to clean when there are extra people.I can't see that my bookings have increased whatsoever and as a traveler that booked a house through VRBO/Evolve last year, I found the booking process to be a little cumbersome. 

I know it is a ton of information to process and I have been going over this 5 times a day in my head.

Let them know you are starting an eviction for everyone on the lease and then start the process. 

. $50k per year you may be eligible.Have you went through the pre-approval process?

Have a process on what you are going to do with these leads. 

The tenant and house have been a huge headache for the owner.

In my many years of experience, if a GC would even consider negotiating, that would be a huge RED FLAG.
