We are fortunate to live in the Austin area since relatively speaking it is consider to be quite safe compared to other similar sized cities/metro areas. It is best to connect with a local Realtor and establish a working relationship. We have many choices in almost any price range across the metro. I find most people first establish an area they would like to live in based on schools, commute & lifestyle. With a little communication and trust I or another Realtor could take great care of you & your family's move. I am available for a phone interview if you'd like.
