You are not going to have a great location for low-mod housing unless you build it.Pick areas that are clean, that don't have a bad reputation (check police calls).Selecting properties one at a time, IMO, really is about location and functionality more than style or amenities, you want a safe, affordable and sound structure.

So for the Arizona LLC, if you are making management decisions, phone calls, models, etc. out of your home in CA, CA may take the stance that you are doing business in CA. https://www.ftb.ca.gov/businesses/bus_structures/LLcompany.shtmlhttps://www.ftb.ca.gov/businesses/New_Rules_for_Doing_Business_in_California.shtml

Expertise, quality of service, and the business model offered relative to your goals will be much more important factors.Selecting the right provider and right plan type will very much depend on your situation and goals.

Buying property with the intent to use it for the vacation rental business model is a totally different kind of investment. 

We can find people to draw floor plans and do 3d models based on the measurements and pictures that you take (people are overseas, so they are inexpensive.

Larger institutions may give you better terms, but can be a pain to work with.Once you develop that relationship with a local bank and they understand your business model, you can almost guarantee your financing.Just remember, EVERYTHING is negotiable.
