Wholesaler and foreclosures

[Joe Farrance]

Hello

Today I looked at a foreclosure property for a potential investor as I was talking to the agent he suggested that this might not be legal? 

He mentioned that he couldn’t legally sign a purchase agreement with me if I’m not the actual buyer? 

My question is this 

So how do I get paid from a investor if the purchase agreement is done without my signature? What protects me of having the investor go around me?

Thank you

Joe
