Purchasing real estate is a complex and major transaction with many details to be handled. In the majority of cases the seller will be represented by an agent. 

A buyer's representative is responsible for protecting the buyer's best interests. Research by the NATIONAL ASSOCIATION OF REALTORS® has shown that when a buyer's representative is used, the prospective buyer found a home one week faster and examined three more properties than consumers who did not use a buyer's representative. 

A buyer's representative will: 

 …    Evaluate the specific needs and wants of the buyer and locate properties that fit those specifications. 
 …    Assist the buyer in determining the amount that they can afford (pre-qualify), and show properties in that price range and locale. 
…     Assist in viewing properties -- accompany the buyer on the showings, or preview the properties on behalf of the  buyer to insure that the identified specifications are met. 
…     Research the selected properties to identify any problems or issues to help the buyer make an informed decision  prior to making an offer to purchase the property. 
…     Advise the buyer on structuring an appropriate offer to purchase the selected property. 
…     Present the offer to the seller's agent and the seller on the buyer's behalf. 
…     Negotiate on behalf of the buyer to help obtain the identified property -- keeping the buyer's best interests in  mind. 
…     Assist in securing appropriate financing for the selected property. 
…     Provide a list of potential qualified vendors (e.g. movers, attorneys, carpenters, etc.) if these services are  needed. 
…     Most importantly, fully-represent the buyer throughout the real estate transaction.
