RE: I'd like to extend an apology to appraisers, Realtors, lawyers, and doctors
I think that your solution lies in the fact that these professions DO exist.
Lawyers exist so that you can protect yourself FROM lawyers.
Real estate agents exist to speak with the other guy's real estate agent because he has one.
Doctors exist to understand what the other doctor has said in the medical journals and translate it into 'take two of these'.
Maybe a little oversimplified, but in the ballpark.
