If you thought Facebook Inc. founder Mark Zuckerberg is lucky for becoming a billionaire before the age of 30, then you may be extra envious to find out about the recent refi rate he received on his home.

Yes, Zuckerberg, a member of the oft criticized and envied 1%, just refinanced his $5.95 million mortgage on a Palo Alto, Calif., home at an envious 1.05% interest rate. Of course, he used a 30-year adjustable-rate loan, so Zuckerberg may have to deal with interest rate spikes if the Federal Reserve ever gets around to lifting rates again, which seems unlikely to happen anytime in the near future.

In reality, when you break it down, the Facebook founder is borrowering money for virutually nothing in today's low-interest rate policy environment.
