If you are really set on Philly (be certain) and have PA residency, Temple is the answer whether we're talking about JD or LLM. If we're really just talking about Philly, I don't think you could even justify GULC Tax over Temple.
Miami is really the best tax llm program?? huh.. surprising! I know Villanova has a great program, and the tax professors here are great! I took into to tax here and did well. My professor was hilarious! Temple would be a great bet b/c i'm sure it is the cheapest out of all of them... Not sure if they have a cheaper price if your instate.. I know the llm in trial advocacy has a set price whether instate or out of state. If you want to stay and Philly (and who wouldn't?....Oh except for all the eagles players that just left us this week!) haha go to Temple or Nova...
