Hi John!
I think investing in real estate for the first time for ANYONE or most can definitely bring uncertainty as in whether "am i making the right choice to do this", "what if something goes wrong?", "my first deal might be a terrible one".
While all of those thought can be true, unless you try it, you won't know. right? I completely understand your wife though.
Anyways, I would suggest you to invest in cities you know/lived first. When you come back to the states, is your home in New Bern, NC? Is there any cities you know nearby that's getting more populated or more companies are coming in? if you know any, you can study the area and invest there first. As for meeting the right agent/property manager, I hope that person comes across on this thread for you but find someone that does investing themselves in that area or at least have interest in that area. This would help you leverage their knowledge of that area to help you succeed your "first deal". If that agent doesnt have an experience themselves, maybe meet someone that works under an investor broker as well.(this is not a sales pitch but) my broker has a lot of out of state/country investor clients. So I wanted to pick her brain and learn from her so I joined her firm rather than joining the big people.
Taking your first step is 1 step closer to your goal than taking no steps!
Good luck on your investment journey!
