Considering moving to the south side

I'm interested in moving to Forney, attracted by the affordable new development options, particularly in the Grayhawk and Fox Hollow areas. However, I've come people calling it the new Mesquite, which raising some concerns. Additionally, why does it seem that so many people are leaving the area? Somewhat worries me as a potential red flag. Could you share any insights on these points? Thank you for your time.
