Any RE agents taking advantage of reciprocity?

[Melissa Kirchhoff]

I'm curious if any agents take advantage of reciprocity for investing or such? IL has it with FL and an agent in my office is doing the snow bird type thing and she spoke with another that does similar and said it's amazing, when it's slow in winter in IL, it's lucrative out there in FL. I started thinking this might be interesting to explore, or maybe use from an investor stand point.

Anyone do this and can anyone offer any insight on it from and agent POV or investor POV? Worthwhile or not?
