What Happens to the Sellers After the Non Judicial Trustee’s Sale- IF they remain in their home?

Nope... he has partners/investors.Based on your post, the best way you can make a "business" out of this avenue that you've chosen is to establish this as a business.You will want to formally set up a business with an EIN (LLC, S-CORP, talk to a CPA about what is best for you and your partner).Then set up business bank accounts for that business.Then set up a PO BOX where all of your mail will go for that business.Now a hard money lender or a DSCR lender is going to take you more seriously when you try to borrow money for value add deals.

Since that's in there, is it Their responsibility to know that they have to give a formal 30 day?

My goal is to move the current rentals and all future acquisitions out of my personal name and into formal LLCs for asset protection and anonymity. 

Filing the UD is what formalizes the beginning of an actual eviction. 

I would ask when it will be discussed formally.  

Also, Roberts Rules of Order are critical...you can typically be less formal with smaller HOA's, but you need to understand the intent and fundamentals of RR to maintain order; properly conduct meetings; and properly document meeting minutes.

There will be a public hearing next week followed by the formal vote by the city council on the changes...""

Again, make sure you are comfortable with the risk/ reward on it and the numbers would work.One solution is to put it under contract with an addendum that the seller must receive a “formal decision” thru city of Tampa with corrected “property use” with property appraiser prior to closing.

Nicole congratulations on building a portfolioThere really is no formal training required for you as a landlord, but plenty of books and podcasts, or even look for classes offered to property managers.
