Although you're asking about pricing your home I don't think that's really the question you should be asking. The main questions you should be asking are about how you and the agent are going to sell the home.
If a good agent with a solid marketing plan comes to the table they might be able to get you more money for your home. While a weaker agent comes to the table and says your home is worth less they might be able to sell your home on just price alone. Both agents can sell your home and the market will determine the price.
Clicking with your agent makes a big difference as well. You want an agent who will communicate with you as the listing progresses. You also want an agent who has strong negotiation skills in addition to marketing skills. If no one sees your home, who's going to buy it? If your agent caves too easy you're going to be swayed right into falling profits.
I'm a big advocate for tech savvy Realtors who flood the market with your listing online. Starting here on Trula should be a good indication that your Realtor is with the tech savvy crowd. They should be able to promote your property online and in traditional media if the area requires it. It depends on the home, and its potential buyers.
The market will determine the marketing plan. A marketing plan based on price is a poorman's plan. A discounted or over priced home will cost you money in the long run. If it is over priced you're going spend your money on mortgage payments and common maintenance as it sits on the market. A home priced too low is a fire sale that will cut your profits right off the top in no time flat.
So, interviewing multiple brokers shouldn't be based solely on who tells you your home is worth the most but how they negotiate their commission with you. How they respond to questions about the area, the housing market, job market, local events, etc.. an agent who knows that X festival is held in the park across the street every July knows their market. The agents who don't know which way north is will have a hard time selling your home to potential buyers. Agents who have been in the business for years and years might be the best resources but they might be behind the times. I'm an agent who has a degree in communication design (digital media). I have grown up around real estate and my veteran agent mother is my mentor along with other competent mentors.
I hope you find the right agent for you. That agent shouldn't be hired soely on the estimated price of you home or thier "fee." Some agents are worth less than the typical 3% and some agents are worth 5,6 or 7%.That agents value to you can only be determined by you since you are hiring them to do the job.
