My recommendation would be to look into hospitals nearby and try to market to them to be an option for traveling nurses also. 

We love traveling (next up: Trump's inauguration in January).- Our first investment: A house in Detroit via InvesteerAmerika (handling resales, property management connections, and setup).

Temporary work travelers etc.

You will need to find someone who would rather go back to Costa Rica again and again, like having a second home there, rather than traveling to different parts of the world.  

Since you plan to travel often, focusing on systems and building a reliable team: agent, lender, property manager, and contractor. 

Yes, it must be the rent prices, but also there seem to be a lot of 1 or 2 people travelers needing a small place for a short time.

Since we're In a college town, a majority of our travel demand revolves around the Texas A&M University and the university's events.

Second question is, if we don't live in the city we will invest in, we understand we will have to be traveling often, but who could be a good person to check in on the construction so we don't have to go every week?

If this is your first venture, your presence at the property will be very important, there is a learning curve, factor in your travel time and other commitments.

I've celebrated by buying a home and traveling haha, congratulations to you to!
