Is the best source to obtain all documents necessary to complete a subject to transaction a real estate attorney? Are there other sources?

Thank you in advance BP!

In my experience the best way to do your first subject-to transaction is to partner with someone with a lot of experience with these transactions. They should have a package of documents that they use depending on your state. In my experience atty's are very hesitant about sub-to's and are more likely to talk you out of it than to help you do it.

I like cashflow depot.com They are a great resource of people who are doing the deal and membership to the site is only about $100 for there which is very reasonable.

Hope this helps :)

@Michael Otranto,

Wanted to follow-up. Thank you for your reply. I'm doing exactly that now- partnering with a local investor (who I met at REIA) who is experienced w/ those types of deals.

Have set up two different appointments on leads I received which I believe are very-possible sub2 deals, and he agreed after doing his own research.  

@Michael Q. has some sub to docs at one of his websites, free for download. If you can't find them, you can PM him.
