Under contract, now what?!

[Mark Redmann]

I got a house under contract on Saturday 6/14. I placed a craigslist ad and now have someone interested. what do I do from here? what contract should I use? its located in Pennsylvania. I have a contract that I downloaded from here but its for texas. Also how do I deal with the earnest money deposit? Does my whole assignment fee get deposited into escrow? ALSO it was listed by a realtor so the realtor office had me make out the check to the realtor escrow account. is that who I have the buyer make out his check to? should it be in the amount of the assignment fee? Thanks for all your help!!!!
