It looks like I'm late to the party on this but thought I'd reply anyway. Everything everyone has said is true, both good and bad. I've been here since 2000 and am 49 years old now, live in Northwest Austin (near 183/Spicewood if anyone wants to come visit).
I will add this : I'm not sure if there is anywhere I'd rather live, so we are staying here for a while, despite not enjoying the town as much as we did when we were younger.
And for your daughter moving here, I think that's the point - she will LOVE it here since she is younger and will be new to the town, and won't be able to complain like us old folks about how it's "not like it used to be".
Some of this may have already been said but :
For sure live closer to work as possible. Not sure when she'll be able to save up the $500k to buy a starter home, so renting will be a reality for a while. But also look for the intangibles, like an apartment near green-space if possible. There is a lot of outdoor activity here, which is quite different from Jackson (where I lived for most of my life until here).
East side is the new "cool" area, lot's of new stuff there.
Central Austin around 45th/Lamar is another decent area. Also the "Mueller" development off old Airport road is a newer area w/ cool stuff.
Northwest where I live is typically where families move. But there is also the Domain on the North side of town that some young adults enjoy.
I always preferred dive bars and pubs when I was younger, but most of the new stuff going is nicer and more $$$. You have to look hard to find low-$ bars here now, but I know most girls (like my wife and daughter) prefer the "nicer" places to hang out.
Feel free to PM me, if that's still a thing.
Good luck to your daughter!
