As another mentioned, school rankings are vital when flipping and you can't do anything about that now, but for future, pay close attention to this BEFORE you buy next time, same goes for crime ratings, population growth, and job growth numbers.

I'd also add that depending on the location and population it may qualify for USDA.

From a job growth, population growth and long term hold stand point, Charlotte and RDU areas are both good investments.  

If all goes well, the third unit will rent for 1100-1200 / month- no problem (high population area, so shouldnt have a problem renting it).

About 53% of the small population in Storm Lake are home owners.

You’ll want to choose your markets based on many factors including affordability, jobs, job growth, population growth, cash flow, etc.Continued success!

Population and jobs are very solid. 

And in order to have appreciation there must be net population growth.

This would give you some insight to population increase and supply/demand changes!
