As an added bonus, there's no state income tax in FL. You'll live like royalty on $200k in Miami, and/or save a ton. I invested over $100k on that income over my first year of living frugally in central NYC (even with 3 international trips, NYC COL and the nation's highest income taxes), so you should be able to match or beat that. Including relocation, small index fund appreciation and a small signing bonus, I am $140k richer than I was 12 months ago even while living within 15 min of my office in Midtown.
TL;DR: financially, this shouldn't even be a question. If you lack the discipline to perform well in your job while enjoying the Miami lifestyle, then that's another matter.
