In fact, I'd argue that it is actually the most challenging form of "real estate investing" out there (and I've done it all.. wholesaling, house flipping, ground up development, office, medical, short term rentals, long term rentals)My 2 cents is that you mentor your son to become a rock star realtor.

They're among my favorite tenants, and there are not enough semi-furnished units at the ready near medical facilities.

My client and I just closed on a similar transaction in Queens, where the listing agent/broker was the owner of the franchise, and she was cease and deceased by her clients' attorney for unprofessionalism.

If you are going to be Short Term Renting then make sure the local ordinances and laws support your approach other wise you may find yourself on the nasty end of a cease and desist letter.

However, due to medical reasons, my family and I had to relocate out of town for an extended period last year.

100% of my travel medical professionals have brought their own vehicles.

The organization brings in realtors, attorneys, medical professionals, and logistics people to tell you what resources each particular country has.   

I am SURE you did a background check, you make sure they graduated from a good  medical university, and that they have plenty experience doing brain tumor operations right?

I travel for work in the medical field.

Might be easier to prove you are working a full time second gig and invest in something medical that is in your wheelhouse.
