Take-Home Differences By Model
- Among the top 100 firms, traditional model agents average about $99,931 take-home versus ~$65,000 in fee-based firms.
- Fee-based agents pay far less to brokers but generally earn less in gross take-home.

- Know which agent demographic you serve and optimize services for that profile.
- Focus your brokerage on a clear partner type instead of trying to be everything to everyone.
