Why not contact a Realtor ?
In my opinion the best way to find a property to rent or buy is to contact a professional licensed Realtor.
That's what we do in our profession.. help buyers and sellers and renters to find a property . Once you meet a professional agent, he or she will answer your questions and find you a place base on your needs.
I am not sure about the Caucasian/retired remarks. You just need to mention that you are not driving and need a place within walking distance to transportation and shopping.
Best of luck!!
