^ is some good info. If you can't afford to live in the Westlake, Terrytown, areas, I would recommend looking along the Loop 1 side of town instead of the I 35 side. One the neighborhoods are usually nicer, and two the traffic is much better. I 35 is always a mess. If you need an Agent I know of 2. One specializes in North Austin, Pflugerville, Round Rock area, and the other is based in Westlake.
