I live in that area, and while there is traffic on Six Forks Road, Bayleaf Church Road connects other roads within the Carlyle subdivision, and heads into Falls Lake. It is mostly traveled by residents.
Carlyle is a beautiful subdivision, prices have stayed relatively stable over the past several years. If you are not already working with another agent, I would be happy to provide you with additional information and assist you in what ever way I can.
