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.
