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?

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

However, I am seeing more interest in MTR's and have a colleague that does well buying condos and renting out to traveling medical workers and foreign exchange students.  

I found a house that I like to purchase in a great neighborhood and the exterior looks great for a 1922 stick built house.

Quote from @Mike Grudzien: Two thoughts:1) stay in your STR for a day or two and you'll discover things it needs or that would be nice to add2) use several touch-points to communicate with Travelers/Guests.

How is the condition of the roof, mechanicals, walls, foundation and exterior?

Usually, they take care of exterior maintenance and upkeep plus you have amenities that you can advertise to your tenants.

Why they need to inspect the interior when the exterior is pristine remains a mystery, but we don’t make the rules.

MTR attracts a lot of traveling medical professionals and WFH individuals who need a quiet space during the day, which may not be compatible with families living in the attached LTR.

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.
