Hi "M" !
OK, let me try to make this answer as simple as I can!
I am tempted to address some of the other comments on this blog by other agents, but I will try to stay on topic, and respond to YOUR question.
First of all, you are not locked into using the listing agent - for that home, or for viewing any other homes. You can, however, work with that agent as a "disclosed dual agent" for that particular home, and continue working with him or her as a "buyer's" agent for other properties down the road. That designation will change depending on whether you are viewing company properites or homes listed with other companies. Selecting an agent is kind of like a blind date ( !! ) - if you know that agent is qualified and experienced, and you feel comfortable with him or her, then by all means work with them, develop a relationship, and the outcome will be a positive one for you. If you meet the agent you made an appointment with, AND feel that comfort level, by all means allow him or her to be your agent. In NJ, we have very clear descriptions of what our fiduciary responsibilities are - as a "disclosed dual agent", we cannot put the rights of one party over the rights of the other party. Keep in mind that a "disclosed dual agent " is not just the agent who listed the home, but ANY agent who works for that company. I would certainly NEVER ascribe to the earlier comment posted here to NEVER use a listing (dual) agent..............nor would I ascribe to the statement that I have heard from some buyers who say they ONLY want to work with a listing agent (they think they get a "better deal" that way). By the way, in NJ, any agent you work with SHOULD be giving you a "Consumer Information Statement", put out by the State of NJ, which explains all of the above terms and rights you have as a consumer!
To sum it up - you are not locked in to using that agent, but as a courtesy, moving forward, if you are interested in that particular home, by all means continue to use that agent for that home. She (or he) will be spending time with you, hopefully giving you useful information, so it would be a nice gesture to follow through on that home. As far as whether there is "procuring cause", that would be determined if the agent took it to arbitration in the future should you buy the home through another agent. Don't concern yourself with that aspect..............just find an agent who you feel comfortable with, and develop a sound working relationship. Do not, however, be afraid to work with the listing agent.
Let me address one more thing. My company, along with most of the other companies in my area offer full, written seller's disclosures on all homes. This means you will get to see just what the owner knows about their home - age of appliances, furnace, air conditioning, age of home, any prior termite infestation, water issues etc. I disagree with the gentleman that started you might not get true information from a listing agent..............hogwash!! Today we disclose whatever we know about a home, and ask the owner to do the same! My real estate license would be in jeopardy if I didn't do that, and NO commission is worth that!!
Good luck in your home search - and if you don't already live here - WELCOME to NEW JERSEY !!
