Bankers Systems does have a stand-alone program that produces both ARM disclosures and HELOC disclosures. All you have to do is choose your index, make sure it's updated, and answer their questions. It will produce what you need. I think they are going to discontinue this product because they are slowly integrating it into their loan documentation systems. It is DOS based but easy to use.
