My wife is Spanish, but I don't have Spanish citizenship.

I’ve been told by brokers and realtors that it is incredibly unprofitable and unrealistic to purchase properties in the states without dual citizenship.

Eric, CEO of Google, has renounced his American Citizenship for tax purposes.

If Arizona had any brains, what they would've done was say anyone living in the state must carry proof of citizenship at all times.

I hold three citizenships so I truly subscribe to my philosophy of "Live where you want.

So given that, it would be very difficult to find a lender who will loan you the money.Personally I lived in Australia for 10 years but I'm lucky enough to have dual citizenship so I can go back and forth with no problem.

Dude if you were born in this country and or have gained legal citizenship, you have every right to put a purchase contract on anything your heart desires and turn around and sell that contract to anyone your heart desires.    

My intention is to gain a 10000 foot view to start with regards to legalities of ownership (example, Costa Rica allows fee simple ownership, but through a corporation owned by the investor), lending - will the country you wish to invest in have banks willing to fund or is it best to find funding within country of citizenship...

What is your US citizenship status?

Unless the OP is a kiwi, Australian, or Singaporean or knows of some slick loophole, he wouldn’t be able to buy property there anyway (without first being granted citizenship).
