Am I leaving too early?

Just wanted some advice. I’m a recent grad, graduated with ok grades from a T-60 law school and just passed the FL Bar. I’m currently at an ID firm and just got an offer from a boutique real estate firm, which is exactly what I want to do and hope to try to take that skill into big law. I’ve only been at the ID Firm for maybe a month and a half. Would I be wrong to leave the ID firm? It’s not really what I want to do and ID lawyers are all over Florida and I feel like it wouldn’t do me much good if I want to try to get into big law.
