Broker Commission Disclosure: Broker commissions are not set by law and are fully negotiable.
How working with a buyer's agent works: I work for you, not the seller. Before I show you anything, New York brokerage rules ask us to put that in writing: an agreement and a disclosure that say I work for you and negotiate on your behalf. The agreement is non-exclusive: you can work with other agents, it runs for a short fixed term we agree on, and you can end it with a note. You may attend open houses independently without an agreement. Read how it works
