Cosmo - I personally don't know Phoenix well, but if I had to do this in another city I would look at income levels, crime levels, and population growth (if you can) by zip code and/or area within a DMA as a starting point.

So I wonder if I can sell my home in Idaho, purchase the new one under my personal name, then how many months or years must pass before I can setup an LLC as the owner of my primary residence, or if you think that will be a good idea? 

Remember that for most owners, their business is very personal to them.

Although the journey has been worth it, I've sacrificed quite a bit from a personal lifestyle perspective, relationships, etc.

Where buyers/tenants can view dozens of properties in a day to screen out less desirables then schedule with a real agent to see the home in person!

The answer to this question is really a personal one. 

Was that person me or another person as that sounds like something I have been telling people? 

@Enrique Toledo  If the seller is firm at 10% down, you can always get a personal loan for that 10%. 

.: My question is… Do people promote buying rentals due to some sort of  personal benefit/conflict of interest?

It should be from someone who uses that person.
