How do I transfer the deed at the end of a contract for deed?

[Moises R.]

Hello, I sold a home on a contract for deed. The buyer is going to be paying off the balance early, with cash. I also have no mortgage on the property. 

My question is how do I actually transfer the deed to the buyer? Do I need to do another closing at a title company (I closed at a title company when I sold it to him)?

Is this something I can do without an attorney or title company?

I would really appreciate any advice.
