I'm curious about this too.. There is an older thread in this forum where folks chimed in last year with their estimates of how many more loans they would need to report with the inclusion of HELOCs. It sounded like quite a few for most folks, so it would be interesting to hear if that's how things are looking so far this year.
My opinion, take it for what its worth. Opinions expressed are my own and not those of my employer and are not legal advice.
