You are doing the right thing by taking some time to figure out who is the best realtor for marketing your property. Here are a couple of ideas for finding a realtor. As mentioned before , go to friends and family in the area and see if they know any realtor(s) that they would recommend. Second, drive in your neighborhood and see if one agent seems to have the majority of listings, specifically those with the sign under contract or pending. You are not just looking for an agent to put your home on the market, you are looking for an agent to get your house sold. Third, do what you are doing now. Explore some of the real estate websites like trulia, zillow, active rain and see which realtors are prominent there. Once you have two and preferably three realtors to choose from, have them do a marketing and price presentation for you. Ask how they came up with the price, how they are going to market the property, who are the target markets for your house, etc. This should be in writing so you have something to hold them accountable for. Finally base your decision on who you think will do the best job marketing your property and who seems the most realistic on pricing your house. Many sellers make the mistake of deciding on the agent by who "gives" them the highest market evaluation on their house. If the agent's market evaluation makes sense that's fine. However, if one agent thinks the house is worth $50000 more than either of the other agents that could mean the agent is not familiar with pricing in the area. Price is crucial in this market. Overpricing your house will make it nearly impossible to sell no matter what marketing is done.
Ken, I would welcome the opportunity to be one of the agents you interview. I grew up in nearby Piscataway and know Somerset very well. Feel free to contact me to discuss this further.
