Hi Josue.
Former Bronx Chick here! :)
I just got my Florida license last month. And the others are correct, there is a lot of costs associated with it. Sure you could get it and put it on inactive. But the license really isn't doing you any good sitting inactive for a year. I would bit the bullet, get my New York license and practice while still there during this next year.
Keep in mind each state has different laws and practices. So what may be OK in NYC may not fly in Florida. So don't go into it with the mindset of "oh I'll just take it again in Florida". You WILL have to take the Florida course and exam regardless if you are NY licensed or not.
Get your NY license, get some practice under your belt, then when you relocate to Florida, you'll have some experience going in. I would also recommend going with a broker who has a national presence so when you do get to Florida, you can stay (if you choose) with the company.
And one more thing. The BRONX is a hot market now??? WOW. I moved away almost 20 years ago and would have never thought of the Bronx as a hot market for real estate. And I grew up near Parkchester/Soundview areas. Go figure. Maybe it's time to take a trip back home to see.
What ever you decide, good luck to you!
