hey future austinites!
i currently live in austin, ((graduated from UT and worked at the university for 4 years after that)) i love austin!
if you live central it is totally possible to get by without a car here, and even easier if you bike.
it gets HOT. INSANELY HOT in the summer, and summer is march through october. wear sunscreen, carry a water bottle and a sweat-mopping rag
it's possible to find some really affordable places to live- i live solo in a little duplex for $550, on the east side (french place/cherrywood- its nice! about a mile away from UT). of course, things can be even cheaper if you have roommates. i have some friends that rent a nice 3/2 house off of 51st + berkman (central-north-east) for 800 total (<$300 each).
things like sxsw + acl are kind of cool, i guess, but really it means that normal life is shut down while they are going on, driving is impossible, restaurants/bars are packed beyond belief.
neighborhood-wise my tips are: stay central. just say no to riverside and west campus. the area north of 29th/west of guad is totally fine though. hyde park has cute homes but is pretty pricey. north of hyde park is cheaper and pretty ok. the east side is definitely not scary or threatening, except the one intersection of 12th+chicon which is a little sketch.
austin is definitely going through some rapid growth phase- condos and gentrification everywhere. barton springs is a magical oasis but on weekends will be comically overcrowded. traffic is awful. but there are some really amazing and creative people that live here! also: tacos, chips + salsa, margaritas.
