For buying a home in Boston I called a realtor and he was so unprofessional throughout the deal. His attempts to show up the houses have always pissed me off as he was not understanding our area of interest. I canceled all the deals with him due to his unprofessional-ism. Then i came across Boston top 20 that included long list of realtors according to their rankings. I picked a few and called them one by one. I got home in just a week. The website was a great help.
