How to Close Seller Finance

I'm looking at a seller-financed deal and am trying to determine how to get the property under contract for an inspection period and, subsequently, how to close. Specifically:

• - Should I use the state RE commission contract to get under contract or is there a more effective way to get under contract? Can I connect seller and I with title company to have the title company attorneys write up the documentation to ensure accuracy and enforceability? 
• - When closing, will title company instantiate all documents or will I need to get someone else involved? 

Does anyone have experience with this? Any guidance is appreciated.
