Travis Heights is great.
Its a little pricey but there are some surrounding neighborhoods near the So-Co aria that are in the Travis Heights Elementary district and are a little more affordable. Its a wonderful elementary school. You can check out the school and neighborhood on line. It has a huge park with allot of beautiful trails surrounding called big Stacy park, and the community is very tight knitted and friendly. There are all kinds of different people living in this aria. Families. Some collage students. Being near the South Congress aria is great too. There are lots of awesome family events that go on through out the year.
Check it about and talk to your real estate agent about this. Assuming you have one.
There are some nice neighborhoods down Lamar aria. From Manchaca to Barton Springs. I wouldn't suggest going any further east past 35. The price may look good but the school is terrible and crime seems to be increasing by the day out there. I made the mistake by doing this due to a bargain I thought I couldn't pass up and realized quickly I needed to get my family out of there.
Good luck, I really hope this helps.
