Wholesaling basics

[Kainoa Jones]

Hey BP community,

Washington state here and I am new to wholesale. I have a good handle on the overall process from resources on this site. Hopefully someone can help fill in some of the finer details. 

-When you find a house to put under contract, where do you find a purchase and sale agreement? Is a real estate attorney needed or are there other options? Also where do you find an assignment agreement?

-How does Earnest Deposit work? It's an agreed upon amount by the seller and wholesaler but where is that money typically deposited? 

-When the buyer has agreed to purchasing, all the paperwork is handed over to the closing agent. Do the buyers usually provide a closing agent or is this someone the wholesaler must find? 

Apologies for all of the questions. I am pretty excited to get started. I just wanted to start on the right foot. Thanks greatly for your time and assistance!
