    "Lived in current home, located in Cumberland Crossing, for 8 years with husband and daughter. I enjoy that our house is located on a cul-de-sac and my daughter can go out and play without heavy traffic. Also the closeness of our neighbors and how we look out for one another’s home. I am unfortunately finishing up a divorce, so looking for a new home for myself, and my daughter, and my fur baby! Thank you"
