Buyer using realtor

[Chris Harper]

Hello BP,

I negotiated a purchase price with a buyer on a property I have under contract. The buyer is finishing the process with a realtor. The realtor asked me to sign a contract prepared by him using a PA realtor association contract which lists me as a consultant paid by the seller. How would I assure I get paid at closing if I don't use my assignment contract? Would it be beneficial to have me paid by the buyer at closing as a consultant instead?
