Although here is Oklahoma, it is possible to have the agent who is representing the seller of the home, "the Listing Agent", represent you also, but my personal preference is for the buyer to have an agent who will represent you fully. Of course, any other realtor can help you, for any listing, but a Realtor who has the credentials of an ABR, (Accredited Buyers Representative) would be my suggestion to you.
So look for these initials at the end of their name and I am sure they will be happy to assist you.
