How does this impact AZ Real Estate and other states that will get new residents from this disaster?

Even legal immigrants are not reliable numbers because they will/may be short-term residents and also do not have the same benefits or detriments of US citizens.

And how might they impact the investors in states experiencing substantial growth? 

Quote from @Michael Smythe: @Jerry NoguerasRecommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

Being highly analytical—perhaps to my own detriment—I recognize the need for guidance and support from a mentor to help me take the next step and actually pull the trigger on my first property. 

As a community I think we should focus on helping people who have had their housing situation negatively impacted recover as quickly as possible.

Lots of books have had a huge impact on my mindset and fueled my passion for growth.

I encourage you to define your financial goals, as real estate presents numerous possibilities.Building a strong foundation of knowledge and connections can significantly impact your success in real estate investing.

Because that is when the impacts are most felt of everything one has to do with the now pile of ashes. 90 days to do nothing forces people to engage with staying.
