What expectations should I set for a good realtor?

[Lisa H.]

What are your expectations for a good Realtor?  I thought I found a good one but he ended up blowing me off. For whatever reason it doesn't matter, I'm off trying to find someone else--back to square 1.  But what would make a good realtor for an investor?  I don't know if my expectations are too high or too low.  For anyone who has an already established team, what would you say makes a good realtor....or contractor....or lender?
