That would depend entirely on who's fiber is installed in your building and where you're located. If it's Fios or Comcast in a major metro market, you could probably get a residential or business line for as low as a few hundred. If it's a major transit provider like Zayo or Level 3 or if you're not in a major market; expect to pay a few thousand dollars.
