A real estate broker is someone that oversees the transactions that occur during a real estate purchase. The types of transactions that brokers oversee include those relating to both residential and commerical properties. An experienced and professional broker will know his or her local area including the local schools and community functions. He or she will also have an extensive knowledge about real estate laws. Even though a broker is not a necessity, anytime a transaction takes place between a seller and buyer, it is beneficial for the transactions to be overseen by a broker. In many cases, the same broker can represent both parties involved. First-time home and real estate buyers should always obtain services from a broker as this helps facilitate any transactions that take place, and this assures a buyer that all purchasing procedures are being properly followed.
