There may be an obstacle if you have no intention of becoming a US Citizen.U.S.

A little about me, I'm 34, a full time first responder (with no intentions of leaving the job early) and I currently own 2 SFH's in Ohio and WV.

And with no intention of being a wet blanket...In my experience, most US citizens invest in US properties, even when living in Japan. 

I would ask a lender the requirements, and my understanding is that a lot of it comes down to intent.

I had no intention to ever use it outside of my own business.

@Mike Hendrickson USDA isn't going to make you refinance out of the loan, depending on your reason for moving out some underwriters will question your intent when you go to get your financing on the new home.

Their good intentions cost them a lot of time, money, energy, and stress.

I had no intention of lowering the rent.

I have a 5 year Lowe's warranties on my appliances in a nice 3 bed/21/2 bath duplex unit in a very nice neighborhood. Last Wednesday  evening my tenant said the dryer was overheating. I told him it was under warranty ...

Try looking into zillow/Redfin and see what your potential rents you can get near the neighborhood by filtering the bedrooms/bathrooms of the intentional property that you are planning to buy.
