Is it true if I rent it out on Airbnb for at least 2 days before the 100 days are over, I should already be grandfathered in?

I would give her two weeks to move everything out and hand over the keys to an empty apartment.

The other day I started the thread Why do people Buy Property in California? 

In case I have to sell or I quit running STRs I wouldn't want to be under water out the gate.

Welcome to the community, Evan!

This is the way to start in my opinion!

Otherwise, get a HELOC to access the equity to buy a home in AZ.

Nice to meet you! 

Quote from @Kody Smith: without getting too deep into my finances, what my strategy is...1. take loans to buy properties (leverage)2. fix/flip for day to day cash flow income3. use some of the fix/flip income to buy consistent cash flow through:- business acquisition, - commercial properties (MF and store fronts),I have no intention of doing ALL of the management myself, I will hire management as needed (medium term goal)my expected core role is money provider, evaluating the numbers, making decisions, and connecting with investors, wholesalers, lenders, contractors, and property owners.while I am just on step 2 of the journey, I am looking toward step 3 to stabilize, and not worry about if house prices drop mid project or not (or not worry as much) So to be fair this is more about obtaining and growing a real estate business not simply buying rentals for cashflow.

Been looking to expand resources from just wholesellers.
