Exclusive buyer’s brokers work only with buyers and don’t take listings. They’re obliged to help you find the best deals and lowest price. Unfortunately, agency standards have changes so much in the past ten years that real estate agents themselves are likely to be confused about their obligations to buyers and sellers, even though in most places they are supposed to give you a disclosure form explaining your relationship. Bottom line: You don’t truly have an advocate in your corner unless you both sign a contract saying so.
