I think it depends on what you're looking for in terms of lifestyle! Do you want a yard to mow and neighborhood parks? Or more urban living?
Many North Texas neighborhoods are the same in terms of shopping and commute time. You really need to check out taxes, property values, and the specific amenities you seek.
For instance, the White Rock Lake area has some fabulous homes and easy access to the park and Dallas Arboretum. But over in Mansfield, they have all new city libraries with lots of kids activities, a new city waterpark and newer homes.
One good source to ask for recommendations from people living in many North Texas communities is www.vibrantnation.com. This is a social recommendation site for women in their 50's and beyond. These are well-traveled, well-connected women who love sharing their favorites from neighborhoods and restaurants to realtors, attorneys and vacation spots!
