Committing to an Agent

[Josh Jacobsen]

My wife and I are starting to look at buying another house. I have 10-15 contacts who are agents, and my wife is feeling pressure to use the agent her parents use. I'm in the camp that says whoever provides me with the best service is going to get my business. Is there some sort of unwritten ethical code to choosing an agent? When an agent shows you a house, are they then expected to represent you at every house you choose to see?
