He is in a huge market and rents to longer term stays, like traveling nurses. 

I was a nurse for 21 years.

The population has been growing here year over year over the last decade, it is home to The Ohio State University which has over 50,000 students that live here along with those that visit, and it also holds a diverse range of young professionals and traveling nurses to fill the demand of the multiple business corporations and hospitals stationed here.

Neither of my parents were so fortunate, and my Dad's memory care assisted living home ran close to 5k a month, and my Mom's nursing home closer to 6k.

We get traveling nurses, the occasional business person, and transplants who are moving to Denver and want a short-term solution while they search for a long-term house.

Similar things apply for visiting doctors, nurses, healthcare executives and other folks who show up to do business in/around Houston's medical center. 

I offer my tenants the flexibility on their stay as some don't have a set departure date... nurses on contract sometimes go for extensions... or a professional relocating may not know where they want to buy or have an official closing date and we all know how a closing can get pushed.

Thanks for reminding us that one of the best things about working in real estate is the can-do spirit of the practitioners, vendors and investors. 

If you are near the hospital (Baystate) you will always get a few nurses interested in your property, which is comforting to know.

I've mostly had contractors with the Railroad or the Air Force Base, and know others have has success with travel nurses (typically 3 month contracts).
