This is an excellent question and anyone attempting to answer it in 600 or so characters, wlll not do a very good job.  I just spent four days at an NCLC [National Consumer Law Center] conference.  This issue as extensively addressed and I am perhaps as confused as ever on the subject.   The best thing you can do is to purchase the Truth in Lending Manual they sell there.  It is several hundred pages long but it goes into extensive detail about this subject as it is very, very complicated.  When you get into the subject of ARMs that are intexed to the LIBOR rate it becomes an almost unfathomable proposition.
