Selling a house without an agent - process?

[David Robertson]

I've got a flip that we are near completion and I have a buyer lined up to purchase the property.

What is the process?

What do I need to do as the seller?
What do they need to do as the buyer?
What closing costs should I be responsible for as the seller?
What closing costs should they be responsible for as the buyer?
What paperwork needs to be filled out? Who is responsible for the paperwork?

Thanks.
