Question on possible wholesale deals

[Darius M.]

So I received a call today from someone that said they had several homes for sale. After calling him back, they told me that they have access to several unlisted properties in the city and suburbs for very good prices. This person doesn't own these homes, but they are a middle person that would get paid by the seller at the closing. He didn't want to tell me who his contacts were but my question is how will I get paid if I were to bring an end buyer to a deal like this?
