I have sold up in that subdivision and my client loves it. If you are concerned about the crime rate in that area and you have axhausted all these websites, call the Melissa Police Dept. They will tell you if you ask. Plus, you can ask them any other questions about the area.
The further north you go from the DFW metroplex the newer it is. You have that "down home feeling" and yet sophisticated in areas. I would be glad to help you with this if you will email me. Please let me know if you have found another agent to represent you.
