The loan number is merely an internal accounting and tracking tool, it does not play a factor in the determination.
If your new note satisfies and replaces the existing note then you have refinanced the note. Since these loans are not designed to be paid with long term financing they are not temporary loans and would now be reported as home purchases.
If the new note is a renewal of the original note, in other words if the original note is still your legal obligation and the new note is a modification or amendment to that note then you have a renewal which would not be reportable.
Now with that said, I too do not think it is proper to have to report these type loans, however I don't see where they meet the temporary loan classification or any other exempt classification.
