I use a Nevada Series LLC and place each property into a separate Serie, but it's a bit heavy. You need a separate bank account for each one, and separate accounting. Also you don't have AZ Series LLCs I believe, so you would need to maintain the LLC in NV and then qualify it to do business in AZ, which is also extra work.
You may want to separate your rentals from any flip activities, as the rental income needs to end up on your schedule E whereas the flip income ends up on schedule C and you need to pay self employment taxes on that.
If the flip income is enough to bother, you would setup the flip entity as an S corp, take about 30 to 50% (depending on how aggressive your CPA is) of the profits as W2 income (where you pay employment taxes) and the rest as a distribution on which you would not have to pay employment taxes (you will still pay income taxes on both).
Yes you can take money out with owner's draws (from the passive income entities), that's no problem, but I think there is a rule that you should not do it on a regular schedule (like every week or two) or it may be requalified as a salary. You'd need to confirm that with a CPA.
Obviously the entity would pay the properties' bills directly from its account, before you take any draws (not sure if that was one of your questions).
Oh and something else: if you re looking for loans for rentals (as opposed to short term money for flipping), Colony's new single asset loan can be taken in your personal name, without an entity (and no income required, which is what I think you're looking for. You do need good credit though).
