Who pays for opening escrow/title searches ?

[Rod Jones]

Hello Bigger Pockets,

My name is Real Estate Rod (lol) and I am very new to wholesaling. I would love is someone can help me out with the following:

1. Do I open escrow/ do a title search after I get contract with seller or after I get contract with my end-buyer?

2. Who pays for opening escrow/title search; Seller, Wholesaler, End-buyer?
