Assignable Realtor Purchase and Sale Agreement

[Consuela Adams]

Advice please? So I found a off market lead and the seller only wants me to talk to his agent from now on and he also wants to only use a GAR (Realtor) contract, that his realtor will prepare. This is the purchase and sale agreement that agents use when the house is on the market. I've never used this purchase and sale agreement before, what can I have them add to the agreement to make sure my contract is assignable? He also wants the EMD to be 2,500🙄 and sent to the real estate attorney in 3 days😳. He did agree to close with my attorney of choice though. Should I even pursue this? 😒 who's paying the agent? will she get 6%? 🤔 what should I look out for on Realtor purchase and sale agreements?

Thanks for any advice
