That's the other thought, that I buy in other locations, thinking Maryland where I have three other rental. 

I will, however, be changing locations from the Baltimore, MD are to a beach in North or South Carolina.  

I'm sure you can do something similar:LIVING IN THE TROPICS: When accepting this agreement, the tenants confirm that they understand that the home is in a tropical and hot weather location and that occasional wildlife and insects not ordinarily seen in other climates may be on property.

I'm located in Georgetown or Hutto.

Also the area that the property is located, how much holding costs you have if its vacant, how much deferred maintenance there is on the home and many other variables will factor into when to sell the property.

Where is this located?

Unlike, Norman (Oklahoma University is located here), Winter Garden (University of Central Florida is located here), and Boerne is a military area.

It's located in a desirable / up and coming neighborhood (Hixson, TN), has good tenants, and seems well taken care of (will be verifying that with inspections shortly though).

PM rates can vary for a lot of reasons including location, # of units, and level of rental income.

One thing that really helps out is that Zillow has a tool that allows you to draw a circle around a given location.
