New to wholesaling

[Sharnise Stokes]

Hello, I am new to real estate  and was looking to start investing by wholesaling. I recently done a 3 day workshop but I still feel like I need help in getting started! So I'm hoping to meet and interact with people on bp to help gear me in the right direction to help do my first deal and many more to come!! 

One of the questions I did have is once you find a deal, the numbers look good and the seller has agreed on the price to which you offer, and once you find a buyer to assign the property to, what all do you have to have in closing a deal? I read something about escrow, what is that?and do you have to have an attorney to close the deal?

-Thanks!
