Do you need to put Purchase and Sale into Escrow immediately?

[Justin Lau]

Hello,

New to wholesaling, just got this Purchase and Sale Agreement signed the other day and was worried about other wholesalers or buyers trying to go behind my back and doing a deal with the seller. 

If I have the P&S signed with the owner will that prevent other wholesalers or buyers to make a deal without me? Or do I have to officially put the P&S into escrow with title company?
