I can't offer any better advice than what the other members here have already offered. I hope it all goes well with whatever decision you make.

I like Bigtoe reply. Remember most things are Negotiable in Real Estate...start negotiating! If that fails start your own team? Good luck with your decision.

I realize this is a little old, and that you decided to stay put (the right decision) but I wanted to post my viewpoint as someone who is a team leader.

Being a part of a team can be very valuable, and I think its one of the best ways for a new agent to get started nowadays. You get more personalized training, a name and track record you can go out and sell right away, access to leads that you can work, etc. However, I don't think this setup you've described here would be beneficial to anyone...except the team leader. You keep 25% of your commissions?!?! What?!?! I mean...I don't even keep 25% of my team member's commissions! Thats just nuts.

What I do think you should do is find a new broker. Your broker is so important, especially when you're newer. You need someone you can lean on and who will have your back. Sounds like you're doing great...any broker would be happy to have you.

I know its scary looking at having a lull in business, I have been there many times (I too have never liked to prospect and have built a more referral type business). What you have to remember is your fortunes can turn around so quickly in this business, like they did for you here...

Good luck!
