Bookmarked this. Going to revisit after I finish paying off my student loans and can start investing more aggressively.

This is a bit misleading. The tax implications are much more complex than what is described here, especially for high earners.

Great article! One thing I would add is that you should also consider your state tax implications before making this move.
