If you're wanting to become a very junior 7ERA I'd advice at staying in ATL. Also, this all depends on what exactly pulls you to Austin or even FL since you mentioned potentially commuting FL to NYC. You won't have the seniority to manipulate your schedule to make it commuter friendly. Idk where in ATL you live now, but id encourage you to explore the surrounding areas if you haven't. If you're willing to drive 1hr-1.5 hrs to work, the south side around PTC and the northwest side around the lakes and mountains are very different.
You can also pull out a calculator and show your GF what a last minute day turn GS would pay at 7ERA rate lol.
