Cambridge in Johns Creek, Figuring Out Where To Buy, & Should A Seller Clean Air Ducts?

In this segment, we feature Cambridge in Johns Creek in our Neighborhood Spotlight, and I received a couple questions from listeners asking, "We don’t know the exact area in which we want to buy, what’s the best way to figure this out?", and, "My kids have lots of allergies, therefore we don’t have pets. In looking at homes to buy, should we request that a seller clean the air ducts? Are there obvious signs to let us know dirty air ducts could be an issue?"
