There's a really big advantage in working with a buyer's agent; you get a better deal and smoother transaction without doing all the work! There are also elements to a proper transactional process that you may not be aware of. A good agent will protect your interests. You likely already know that the seller pays the commissions on MRIS listed properties, so you have nothing to lose and everything to gain by allowing a professional to guide you through this major transaction.
