We recently moved locations for the 3rd time in 6 months. We have schema markup on our site for several citations. How much will it hurt rankings if we update the address location for the third time?

NEIL: I know it isn't always in your control, but it does hurt a bit each time. You don't want to add additional addresses because it will confuse people when they search as they may show up to your old location. I would just bite the bullet... no quick solution to get around it.

Another Take: You certainly can, but think from a user perspective. You definitely don't want to be promoting an address that you no longer operate at! Taking the small, impermanent SEO hit makes more sense.
