Closing procedure for RTO or sub2

Does anyone know the closing procedure for a RTO
and subject to?

Should I have a title company handling a RTO/Sub2
closing or record the documents at the courthouse?

If I want to record the documents, can I do it with
a notary public?

I am planning on doing these type of deals out of
my state and I was wondering if I could record the
documents without going to the courthouse.

Also if there is no title company involve in this kind of
deal, do I simply have the tenan/buyer send the check
to me through mail?

Is there a better and faster way through the internet?
Or is sending a check through mail is the only way?

I am not sure how a RTO/Sub2 closing is really done or
if I ever need a title company to do one.
