What’s a discount agent?
Let’s first start with the word “discount” in the question. There isn’t a discount when a company offers a lower cost. This is misinformation usually put out by the companies that charge a much higher cost. Let’s be very clear:
There are no set fees, or commissions, in Real Estate!
As for different companies doing the same job, that depends on the individual agent. I’ve worked with different agents from the same company. Most did a great job, and some not so great. This is why it’s very important to interview several agents. You want to compare their marketing plans (click – compare brokers). Remember to get the verbal agreements in writing, and then add them into the Agreement.
There is a CBS news report “Hi-Tech Real Estate Moves In” that I recommend viewing prior to interviewing different agents.
