Creative finance paperwork

[Jourdan Mercer]

I'm a new investor trying to get my first property using creative financing.  I would like to get my first property or multiple properties using seller financing, sub to, or a hybrid of both.  I'm trying to do my homework and make sure I do it the right way.  Is there certain paperwork I need and what is the best way to handle a sub to title transfer to lessen the likelihood of triggering the due on sale clause?

I'm also looking for a real estate investment attorney to bring my paperwork to when I get my deals and to look over my contracts.  Any investor attorneys in massachusetts from worcester to the cape looking for a new real estate investor to work with?
