Yes, but why would you? You can hire a Buyer's Agent. A Buyer's Agent will be representing you and not the seller(s). Often, the Buyer's Agent will be paid by the seller.
The reason you want to consider using a Buyer;s Agent is the Seller's or Listing Agent was hired to represent the seller(s). Thus, it's his or her responsibility to sell the house for as much as possible. They will negotiate a deal that's in the best interest of the seller and not yours.
The Buyer's Agent, on the other hand, will prepare comparisons to recently sold properties that are like or nearly like the one you want to purchase. They will help you determine the appropriate range that the value of the house should be in, and help you negotiate a "fair deal."
