I don't live in Austin but I have been there many times.yeh there are Nepalese but compare to Dallas and Houston there are  lesser.The place is best place in Texas. There are hills, lakes , parks when I visited first time I felt like I'm in Nepal. Its way better than Dallas or Houston.The land is not that flat so driving  uphills, slopes really makes  feel like drivin in Nepal. I strongly reccommed u to live in Austin. About costing its not that expensive same like Dallas  . Transporation wherever u live in Texas u gotta have car.
