My current focus - what is the process once a family member/individual has passed and lets just say in a perfect world probate has been filed and the respective family is now thinking about selling the property.

If you go gung-ho, follow substitute trustee (S-TR or equivalent) filings in your county. 

If it is more than one investor and pooling funds and deals then that is a completely different animal where you would file for a SEC exemption through a form D then ahve to file with each state the investors are in and have a subscription agreement and other docs drafted. 

For a list that small you may get lucky and no one will notice but in general you can easily run into frequent litigators that are just waiting to get called and file suit.

What would I need to update / re-file? 

So now i need to file a dispossessory action to evict them under unlawful Detainer.

Hello, My name is Mike Johannes and I am the Business Development Manger at Mosaic Property Management, a full-service PM company based out of Gilbert, AZ.

If you get audited, this will be good to have on file.3) That's tricky, the dash 4 grouping election is based on facts and circumstances.

Just make sure you file your taxes correctly.

Hello @Ricky Hernandez,Though I'm not familiar with what is customary in AZ, I'd recommend a home inspector over a contractor/handyman.
