The following was published by the National Association of Realtors.  It shows the differences in the origional plan, and if you've been in your home for five years, and want to move up, there may never be a better time than now.  Here is an outline of the data:

I hope this helps clear up the information and if you have any questions, just give me a call.  Cherie
