Jade:  There are hundreds of real estate agents available.  Sellers and buyers usually choose one based on "word of mouth." recommendations from friends.  A "sketchy" reputation will tremendously harm an agent's reputation.  Conversely, a solid reputation beats thousands of dollars in direct advertising.  

I'm facing serious cognitive dissonance regarding this story.  I have great respect for Mr. Nelson's expertise and integrity.  On the "flip side", the allegations in this story are quite serious.  I'm unwilling to "throw Mr. Nelson under the bus" as some other posters are doing.  At the same time, I have no basis to simply dismiss Mrs. Collins' accusations as totally unfounded.  

I don't know how this case will be resolved, but feel the only fair course is to let it "play out" through the judicial system.
