Liberty Estates in Braselton, Massive Swath of Land Sells For Homes, & What is radon gas?

In this segment, we feature Liberty Estates in Braselton in our Neighborhood Spotlight, I found an article about how South of Atlanta, massive swath of land sells for 1,000+ more homes, and answer a listener question asking, "What is radon gas? Is it present in GA? Should I have the home I’m purchasing tested or inspected for radon? If radon is found, what is done to clean it up?"
