Get your right realtor

Recently my sister is planning to buy a home, she has been dealing with some real estate agents, but, what the badly services she experienced from those unprofessional agents. They just couldn't provide the useful help for my sister. How i wish my sister can find a realtor like those from GMAC Real Estate, the service they provided has average 94% proven satisfaction in the real estate industry. I think if the realtors in my area really want to success their business in real estate industry, they definitely have to learn from the realtors from GMAC Real Estate.
