Assignable Contract vs Purchase and Sale Agreement

[Nate Ollie]

Hey guys, looking for a little guidance here with something for my first deal: I am in the midst of putting my first house under contract. I went through a realtor to find this one, and I told him today that I wanted him to draft an assignable contract and gave him an offer amount. He responded and said that he didn't do assignment contracts and said he could draft a purchase and sell agreement instead. What I want to know is if I should just provide the agent with an assignment contract that I have and have him present that to the seller, or what other course of action I should take since I want to wholesale this home.
