I want to buy a apartment complex, but don't know where to start.

[Earnest Mallard]

I live in Tucson AZ, and interested in buying a apartment complex or multi family home. I don't have much money and do not know where to start to look for money to purchase one. I have owned two homes but they were homes my family and i lived in. I'm trying to figure out where to apply for a loan as well as how much I should try to apply for since I've never done this before. I'm a retired veteran and wonder are there programs out there that will assist veterans when it comes to borrowing money to purchase real estate for profit. Thanks for any and all advice.
