I would suggest Flower Mound itself, Grapevine, Trophy Club, Colleyville. Aubrey would be great for your wife but for you it would be at least 45 minutes. I'll be happy to send you a sampling of listings so you can map them and see what you can get for your price range. Feel free to email me directly with your wants and needs and I'll put something together for you.
I am thinking that South Lake is the communcity. I jsut don't know whihc subdivisions to stay away from and whihc ones to gravitate towards. Grapevine looks nice, but the lots all appear to be on the smaller side.
