As an agent here in McAllen, I can provide you with the information that you need. Let me know what your requirements are and I can send you a list of apartment buildings that match your needs.
We do have some gated communities that seem pretty secure. We also have some that work primarily for people in the medical field and are near the hospitals.
I would be happy to help you in any way I can.
As far as safety, I can recommend that you call the McAllen Police Department non emergency number and as for the person in charge of crime statistics.
