I am assuming you are an agent. If you are not - then this answer won't matter much to you.
First - remember at all times that you are a walking checkbook. You will have to pay someone (the owner of the company) to have an office, staff, licenses and all kinds of goodies for us to work smoothly. Now it's up to you to decide what services you need and how much those services are worth. That's your split, 70/30 50/50.... whatever they offer. Some companies have 1,000+ agents and one or two managers... not a good deal if you are new. If you are new - sink some of your commission into education... go check out other company's education. Go to their meetings to see if these agents are really getting the education they need in this swiftly evolving market of short sales and foreclosures. Too many agents listen to the recruiter and sign up without checking things out for themselves... then they've lost valuable income producing months. The key to income is education... pop into Realty Executives 1903 S Jones on thursday morning for Short Sale meetings, and then look for the same if not better at other companies... you need education before you need a team.
