Who will work harder for you, an agent associated with a large franchised company or an independent? Who will be smarter? Who will be more motivated to do a good job for you?
One thing most real estate agents have in common is that they are independent contractors. Even agents with large firms with franchise names are not employees of those firms in most cases. Traditionally a brokerage has provided agent/independent contractors with both administrative and marketing support. Sometimes they provide an office or at least a desk in a large office. Many franchises also provide training. For rookie agents a year or two in a large office is usually a good idea because they can be mentored and supervised. Many agents reach to point where what they have to pay for that support in terms of fees, commission splits and flexibility is just too much and they launch their independent real estate practices.
