Wholesaler Funded Property Purchase

[Ikenna Okoye]

Hello everyone, I've been reading about the importance of having cash, or enticing offers when negotiation with sellers for purchasing property. I'm curious though, if you as a Wholesaler spend money to market, to pay contractors to give rehab estimates, are you expected to already have a buyer, your own cash, or prof of funds from a lender when you agree to purchase a property? What would a buyer expect, something like an earnest deposit?
