If I'm looking at a house for sale on Redfin or Trulia,  how would I know if that a good deal or not, if I don't have the insight that a PM have, in respect to what expenses might be. 

Fear is a much greater motivator than respect.

Class B and A hoods can and do turn into C or B hoods respectively.
