This website can give you a lot of info for that, but a few ideas to think of if you are interested in starting right away as a RE investor (recommended!)

These websites are also a great source to gain knowledge about so many things needed to make educated descisions.It's funny you mention Arizona, we might want to connect here on BP to exchange a few thoughts and more specific ideas and perhaps even collaborate.

You can also earn a fee for referring those deals to institutional level investors.

You will still be able to dictate who you rent to based on credit score, criminal background, landlord references, work history etc..

Was referred there by a real estate agent and just trying to do my due diligence. 

Any buyer pre-auction will want exclusivity rather than competing at the auction, so you may be able to negotiate a sale that includes a portion of his profit, which is the reference to a joint venture. 

What I can recommend is reading the free LEED for Homes guidelines on USGBC's website as well as other green home ratings such as Enterprise green communities and Earthcraft.

I will refer a great lawyer to you.

Halo @Freddie Williams , it is totally possible. when you are referring to commercial i take it that you are referring to 5 units or more? 

Chris, I haven’t used First United for a duplex, but do have experience working with them on traditional mortgages and to be honest I’m not surprised they got their info wrong, their knowledge and customer service isn’t the best (and their website isn’t user friendly at all) I would definitely talk to other banks.
