ITT: Mostly poor advice from people who do not know anything about the legal market in Florida. Seriously.
I had major personal and professional ties to Florida. I worked and lived there for six years before law school. Worked in a local firm 1L summer. Was above median at GULC going into OCI and didn't even get callbacks at some of the big Florida firms. I got two offers for 2L SA positions, at regional firms.
Mostly because they simply were not hiring. This is due to the terrible, terrible prospects in FL BigLaw. Firms hire like 40 total SAs each year, maybe less now. Big Miami firms like Hogan and Weil are cutting back their offices in Miami. Akerman has not had a summer program for offices outside of Miami in like three years. Holland & Knight is overexposed and hardly hiring anyone. Greenberg was processing like 30% of BoAs foreclosures in the state for fixed prices, like $4,500 per case. Regional firms like Broad and Cassel, Gunster, and GrayRobinson mostly do work like bankruptcy, foreclosure, and family law. Business litigation focuses on construction contracts. There are some firms that do wealth planning if you think you would be into that. The legal market in Florida is very dependent on the Real Estate market, and that has not recovered in FL, yet.
The bottom line truth is, without ties to FL or serious grades from a T14, you won't get Florida from a school outside of FL. I can't speak to Vanderbilt in Florida because I have no idea about that situation. I can say that of the 50 lawyers I know in big and regional firms located in Florida, none of them went to Vandy. I will tell you that people with latin honors from T14 schools have trouble getting into FL firms. If you go to UF and get top 10 grades, you will have the ability to work anywhere in Florida. Law firms and the state government love UF. I got beat out by people at UF for positions at GT and HK because they had great grades at UF. Also, think about knowing spanish because mostly all the Miami firms will strongly prefer it. A majority of business people in S.Fla. consider spanish their primary language.
The best advice anyone can give you is this: go to the best school possible given your financial situation, do the math on what makes sense for your family, and do the absolute best that you can in law school. Take in all your options because you may think you love Florida now, but you have not lived there. I lived in the area that you claim to love and will tell you that living there is different than visiting for a few days, weeks, months, etc. There is hardly any culture or entertainment, a fair amount of shitty people (like anywhere), and you have to drive everywhere (traffic blows and drivers are phenomenally bad at driving). Who knows, maybe you go to UVA and get a job with a firm in DC and end up loving it there...
