State capitals, major universities, major health care complexes, logistical hubs like inland ports (though these are subject to economic ups and downs, they are so expensive and time-consuming to build that they are not abandoned and they are hard to compete with in the short-term.)Hope this helps.

Which neighborhoods are better for Midterm rentals (demographic is corporate or traveling healthcare)? 

There is a national convention for the health care assoc I belong to the same time as this one. 

Most Millenials I know 1/2 are smart, tech savvy and making money [good tech jobs or healthcare etc], the other half not so much. its like that every generation.

If you are an engineering major, or healthcare or other in demand career field I would suggest taking full advantage of that.

I work a full-time job in the healthcare industry and my interest towards real estate investments in Charlotte stems from how beautiful of a city it is and my thought that in the coming 5-10 years, it is posed to experience aggressive expansion.

Would like advice on markets to focus on - my key hypothesis is to focus on markets with decent employment rates, growing population and presence of contemporary industries such as tech, healthcare, finance, etc and not relying on manufacturing/agriculture.

You can find some terrific tenants in the healthcare industry, as well as respectable "working class" professionals. 

@Mike Nas I like medical and dental and vision (anything healthcare).

I think about éxiting healthcare every minute of my life as hospital work can be atrocious regardless of the high pay.
