Property tax question on foreclosure resolution

Got a summary today for 3701 W Kilbourn Ave which posted a 50% loss after 3 years. That in itself isn't all that surprising with GF, but in their loss details they sent, somehow they paid $40K of property taxes on a $75k property. Property tax history in Zillow shows about $2k a year. Anyone have an idea how this makes sense?
