What markets and strategies are you intersted in? 

Welcome, Richard - What property types / strategies are you intersted in? 

Right where interstate 79 and 376 meet so great location.

To avoid the risk management/insurance that comes with tenants' wood fire use:I'm thinking to seal the chimney cap on roof and run a cord putting an electric Infrared heater fireplace in there, so they can still open the glass and get heat and watch TV over the mantle, but can't burn anything or have any flame.

after seeing all the risk management/insurance that comes with tenants wood fire usability, I was wondering the same, or, actually:   I'm thinking to seal the cap on roof and run a cord putting an electric Infrared heater fireplace in there, so they can still open the glass and get heat and watch TV over the mantle, but can't burn anything or have any flame.  

Also get cordless blinds, because cords can be a choking hazard for kids, and they look messy. 

In addition, I am considering changing my furnaces/boilers to have plug-in cords instead of being hard wired so that if there is a power outage in winter that I could power that heating system with a portable power station.

That being the next "big" city along the interstate but you are talking about smaller cities even further south than that.To attract more interest, a higher population and greater economic or job growth are necessary.

Admittedly, pricing will often account for any major items, and I don't believe this is true in Sandy Springs, but there are some areas that an interstate cuts off a small part of the neighborhood, and so labeling the neighborhood as "good" may be true for 90% of that neighborhood, but if you are in the 10% that is on the "wrong side" of the interstate, it can be a totally different market.

It is very intersting to see what markets and why you as experienced investors go for that market.
